    Is there was an insert we could put in place of our current insert that would allow us to enjoy a fire from both inside the house as well as outside on our deck?
    By Collin C. - NFI Master Hearth Professional on July 29, 2013

    There are some manufactured gas fireplaces that can be configured for an indoor/outdoor see through application. However, we do not offer any wood burning models that are equipped in this way. The primary issue is with the lack of insulation in the wood burning units.

    I have had some customers purchase a see through wood burning unit, then have a custom fireplace cover made for the outside of the unit. The cover would be insulated and made of 304 of 316 stainless steel and would be left in place and locked (for security) when the fireplace is not in use. A sheet metal fabricator would need to produce the cover, based on the measurements of the unit.

    By Vann from Middletown, DE on October 14, 2013
    I have a vent free gas fireplace. How can I change to a vented fireplace? Do I choose a vented insert or replace the entire fireplace (including the mantle and all)?
    By Tyler M. - NFI Certified Specialist on October 15, 2013

    Of course, your vent-free fireplace would need to be completely removed with a new, vented unit put in its place. If you are on an exterior wall, you can simply run a rear vent kit out the back of the fireplace and through your wall, and your mantel may be able to stay in tact.

    By Mark from Culbertson, NE on November 30, 2015
    How do you remove the brick liner and baffle on a Majestic 380IDV fireplace insert so you can take the manifold off?
    By Will M. on December 1, 2015

    This will involve removing the glass to remove the bricks via the retainer clips that hold them in place. After this is done, the baffle should easily be removed. Clarity is provided for removal of the manifold on page 14 of the installation manual.

    By Sharon from ME on June 6, 2015
    My fireplace is too shallow for a fireplace insert. Is it OK to have a mason make room for an insert without taking down the fireplace?
    By eFireplaceStore on June 7, 2015

    It is certainly possible to build the fireplace opening out in order to house a fireplace insert. You will only need to ensure that any combustible foundation or flooring is covered with noncombustible masonry or cement. You will also need to make sure the flue collar on the unit will not fall directly beneath the lintel, as this would cause issues with venting the insert.

    By Julie from Kernville, CA on December 29, 2013
    I'm looking for a wood burning fireplace insert for my river rock/stone fireplace. My fireplace at the front is 36 inches wide, 29 high and 25 inches deep. The back of the fireplace is 26 inches wide and 16 inches high. The middle of the fireplace has a height of 27 inches. My house is 1500 square feet, one story open plan with low temps of 30- 50 degrees in the winter.
    Would an Osburn 1800 fit in the space I have and will it be big enough to heat the whole house? We have no other form of heating.
    By Collin C. - NFI Master Hearth Professional on December 30, 2013

    Per your dimensions, the Osburn 1800 will indeed work for your application. As long as the fireplace is centrally located, the insert would be sufficient in size to heat the entire space. Circulating fans of some sort will assist greatly in evenly distributing the heat.

    By Ken from Birmingham, AL on October 27, 2016
    Do I need to remove my existing fireplace to install an electric insert? Thank you.
    By Will M. on October 28, 2016

    You would not need to remove the existing fireplace to install an electric insert, but you may want to remove the inner refractory to provide more space inside the fireplace opening. A model to consider that appears to work with your dimensions is the Modern Flames ZCR Series Electric Fireplace Insert with Trim - ZCR-3824 as this also offers optional trim to cover the remaining void left between your existing fireplace opening and the outer shell of the insert.

    By Jay from NY on April 19, 2013
    I'm looking for a burner, sand and any other parts I would need to go with my natural gas brick fireplace, logs and pilot light setup. Can I use the Real Fyre burners that you sell?
    By Chris on April 19, 2013

    The Real Fyre burners that we have available on our website are only designed to be used with appropriate Real Fyre log sets. If you could reply with the dimensions of the fireplace pictured, we can recommend several replacement sets that would fit the fireplace.

    By Monica from Harrisburg, PA on January 6, 2014
    We have a gas fireplace insert as part of our fireplace. It is directly vented outside. It is 16 years old and is no longer working. Can we just replace the logs, or do we need to get a complete new gas fireplace insert because it is a direct vent fireplace?
    By Collin C. - NFI Master Hearth Professional on January 7, 2014

    Direct vent fireplaces are constructed with the log and burner system as an integral part of the unit. As such, the entire unit must be removed and replaced with a different system. If a unit is less than 7 or 8 years old, it is usually possible to procure replacement parts to make a repair, but it is likely that parts for your system are no longer available.

    By Mara from AL on February 17, 2016
    I'm looking for a wood burning insert with double doors. Do you have any?
    By Will M. on February 18, 2016

    Unfortunately, we do not offer a wood insert with double doors.

    By CJ from Cape Cod, ME on May 13, 2013
    Can I add a wood burning insert to my fireplace without losing my existing glass doors?

    By Collin C. - NFI Master Hearth Professional on May 13, 2013

    Unfortunately, no. All wood burning inserts require the removal of any existing door enclosure, as the insert will have a sealed door of its own that must be readily accessed. The insert must also be able to readily radiate heat to the room. Your factory door enclosure would likely prevent this to a degree.

    By Shelley from Sherwood Park, Alberta, CAN on February 15, 2015
    Will the G13600-N fireplace insert work if there is a power outage?

    By eFireplaceStore on February 16, 2015

    The Napoleon GI3600 is a standing pilot/millivolt style of appliance and will indeed work in the event of a power outage. The accessory blower is the only component that will not operate.

    By Robert from Mentor, OH on October 20, 2014
    I have a fireplace that is not working for real wood burning so I plan on putting in a gas ventless unit. The inside of the fireplace was painted with regular paint. Would that be a major safety hazard?

    By eFireplaceStore on October 21, 2014

    If regular latex or acrylic paint is used, it would have to be stripped completely before installing a vent free gas log set. The paint would be heated to the point of releasing dangerous fumes into the room.

    By Michael on November 9, 2012
    We have a Napoleon fireplace and have noticed that there is a red light flashing in the base of the unit. What does this mean?
    on November 9, 2012

    Usually, the control board will have an LED light that will flash to indicate some sort of fault with the unit. The number of times the LED flashes, before pausing, will indicate exactly what the issue is. There is a troubleshooting guide with a table in the owner's manual that will help to decode the issue. What model of Napoleon fireplace do you have installed? I will be happy to check into the issue for you further.

    By Martha on November 9, 2012
    We have had a Dare IV fireplace insert for over 30 years with no problem until now. We replaced the fan motor a year ago and need a new fan motor switch but cannot find one. The switch we have will not let us select a speed. It runs on high all the time which makes it noisy when trying to watch TV. Do you know where me may get a fan motor switch?
    on November 9, 2012

    Most fans are designed the same way from brand to brand. The fan switch is usually a rheostat type of control that will turn the fan off and then gradually increase speed as the control is rotated. If this is indeed the way the fan operates, I will need to know the rated amperage of the fan motor to see if we have a rheostat that is compatible. There should be a label on the fan itself that gives voltage, amperage, etc. Please let me know and I will be happy to help.

    By Britt on November 9, 2012
    The opening to my fireplace is 33.5" wide, 22.5" high and it is 24.5" deep. I would like to know which inserts I can use to burn wood that will fit.
    on November 9, 2012

    Please see some of our suggestions below:

    Fireplace Insert 1.

    Fireplace Insert 2.

    Fireplace Insert 3.

    Fireplace Insert 4.

    We have several others, as well:

    Fireplace Inserts.

    Each insert's item page should list the required fireplace dimensions needed for installation.

    By Tom from San Francisco, CA on March 17, 2013
    I need a wood burning insert that is less than 21 inches tall to fit into a prefab Heatilator EC36 fireplace.
    By Collin C. - NFI Master Hearth Professional on March 18, 2013

    My apologizes, but every wood burning insert that we currently offer measures between 21 to 23 inches in height. If your EC36 has a metal smoke shelf at the front that is removable, you may be able to gain more height that way. However, if the 21 inch measurement is from the hearth to the top of the inside of the box, I am afraid that we do not carry a unit that would fit.

    By Kim from Southern Illinois on July 25, 2014
    I am in the process of building a new home and I want a woodburning fireplace. It needs to fit in a corner and would like to have the wall built so that the fireplace fits flush against the wall. Do I need a special "corner" firebox or can I use a regular one? If I need a special "corner" unit, then what kind of unit do I need and do you sell them?
    By eFireplaceStore on July 28, 2014

    A standard wood burning fireplace can be used for a corner installation. You will only need to keep in mind the amount of overall length that is needed for the 45 degree enclosure wall. Some fireplaces are deeper than others, necessitating a larger enclosure. If you will have windows on the walls adjacent to the enclosure, you will need to ensure that they will not be overtaken by the enclosure wall.

    By Lee from Clinton, IL on September 11, 2014
    I have an older Superior model FirePlus38 fire place. I've replaced the refractory panels, screens ,etc. I'd like to replace with a high efficiency wood burning fireplace insert but it looks like all of them are required to be installed in masonry construction. My current fireplace is in a freestanding wood framed chase with drywall around the firebox. Can my existing fireplace be replaced with a sealed combustion heating unit? And if so, what sort of contractor should install it?
    By eFireplaceStore on September 11, 2014

    We do indeed carry a unit that functions like a high efficiency fireplace insert, but can be enclosed into a combustible framed wall. The unit is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace. This unit is essentially a wood stove encased in a special chassis to maintain proper clearances. A licensed general contractor would be able to reframe the opening and install this model, along with the required chimney pipe.

    By Michael from Bridgeport, Texas on June 18, 2014
    I want to replace the firebox attached in the pictures with a fireplace insert that will be much more efficient with my wood. Can it be done and what will it take?
    By eFireplaceStore on June 19, 2014

    Per the manufacturer, the Heatilator EL36 is rated for use only as an open faced wood burner or for use with vented gas logs. It does not have the capacity or proper insulation to house a fireplace insert. As such, the unit would have to be removed and replaced with a high efficiency close clearance fireplace. Our most popular model in this category is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace. The existing framing will likely need to be altered, along with lining the existing chimney to fit the 6 inch flue collar on the new unit.

    By Bruce from Kenmore, Washington on February 18, 2014
    Do any insert manufacturers construct an insert for a pass-through fireplace? I have a fireplace that is open both to the "front" and the "back" (the living and dining rooms are separated by the fireplace/stone work) and is a major feature of the house architecture.
    By Collin C. - NFI Master Hearth Professional on February 18, 2014

    I am not aware of a manufacturer that currently offers an insert for two sided applications. While this request has come up several times before, the manufacturers I have spoken to do not have any current plans to produce such as unit I apologize for the inconvenience.

    By L from Boston, MA on November 19, 2013
    Several years back I purchased a gas fireplace insert. I have tried to light it this year and I am having difficulties. I got it lit once but have failed since. The pilot is lit. What can I do to troubleshoot the issue?

    By Collin C. - NFI Master Hearth Professional on November 19, 2013

    It would seem that the thermocouple is not generating sufficient voltage to hold the valve open or there is significant voltage drop within the thermocouple lead that is causing the problem. With the pilot off and the unit cool, the thermocouple probe should be lightly sanded to remove any soot or combustion by products that have built up. Then, follow the copper lead from the thermocouple probe to the gas valve. The nut that is holding the lead in position should be loosened a couple of turns, then snugged back down. This will seat the lead into the gas valve and eliminate any bad connection that could be occurring. In most cases, this resolves the issue you are experiencing.

    By Ashley from Fairhope, AL on May 28, 2014
    I have an indoor wood burning fireplace/chimney with a prefabricated box that is on an exterior wall of my home that backs up to the patio. Can I remove the existing fireplace box, knock out the bricks on the exterior wall and insert a box that will make the fireplace a see-through design? My goal is to be sitting in my TV room and look through the fireplace to be able to see outside of my home to the patio. I would obviously have to add glass doors. Can you please help?
    By eFireplaceStore on May 29, 2014

    It may indeed be possible to perform such a conversion, but it will depend on the structure of the chimney. We offer see through direct vent fireplaces that offer an outdoor glass panel to properly seal them from the elements. It will require that you remove the existing wood burning chimney piping and replace it with direct vent gas piping. However, your brick chimney likely does not have the support necessary to hold the brickwork in position if such a large hole is made in the structure. You will need to consult a skilled mason to discuss the possibility of supporting the brick so that the veneer does not sag or collapse when the exterior pass through is made.

    By Brendan from Silver Spring, MD on January 1, 2015
    I'm looking for a vented fireplace with a width less than 31 1/2 inches. What would you recommend?
    By eFireplaceStore on January 2, 2015

    One of our most popular smaller vented units is the Napoleon Vittoria Direct Vent Gas Fireplace - 19-in.. The overall framing width of 22 inches is great for installations with limited space.

    By Patricia from Levittown, NY on August 31, 2013
    Do you have wood burning fireplace inserts for see thru fireplaces? I have a see thru Levittown NY fireplace. It is open on two sides - front and back.
    By Tyler M. - NFI Certified Specialist on September 3, 2013

    Unfortunately, no, we do not carry any two-sided woodburning inserts at this time.

    By Medger from Louisville, KY on January 20, 2013
    I am looking for an electric start for my store bought fireplace. I want to replace it from the extreme heat gel.
    By Tyler M. - Fireplace Specialist on January 21, 2013

    Depending on your unit, you may or may not be able to install an electronic ignition. Please reply with the manufacturer and model information of your fireplace/insert, and we will research available options for you.

    By Earl from Groton, CT on January 21, 2013
    How do you determine the make and model of the fireplace if you do not have any paperwork available?

    By Tyler M. - Fireplace Specialist on January 21, 2013

    Depending on your unit, there are a few places the manufacturer information may be located. The first location would be a metal plate that is on the left or right side of the smoke shelf bracket, right at the top of the fireplace front opening. The next place would be just on the inside of the opening, behind the fireplace screens on the left or right side. The last location would be in the void space underneath the fireplace floor. This can be accessed either through the front of the unit's louvers or through a removable floor panel underneath the bottom refractory.

    If you have a gas fireplace or insert, the information may be found on a data plate or sticker located near the pilot assembly.

    By Bob from Columbia, MD on February 16, 2015
    Do any of the ventless natural gas inserts come with a fan to push out more of the heat?
    By eFireplaceStore on February 17, 2015

    The vent free fireplace inserts we carry do have a circulating blower as standard. This helps to make maximum effective use of the heat generated by the appliance.

    By Thomas Robinson from Bath, NY on November 18, 2012
    Are thermocouples for gas fireplace inserts universal?
    By Collin C. - NFI Master Hearth Professional on November 19, 2012

    Thermocouples are different from unit to unit. While some thermocouples in home improvement stores are marketed as "universal", they will not work for all appliances. Millivoltage for a thermocouple can range from 50 to 250, depending on the appliance. It is important to use a thermocouple that is properly sized to the unit, as damage to the magnets in the gas valve can result otherwise.

    By John from Blacksburg, VA on July 10, 2014
    I have a Superior ventless gas log set that I would like to replace with a pellet fireplace insert. I am looking at the Timberwolf TPI35 (Napoleon NPI35). I will be installing the unit, and cutting out for the vent. Is this a typical installation, and will I have any issues with clearance or placement of the vent?
    By Will M. on July 10, 2014

    As with any insert, you are only allowed to install this in a brick or stone masonry fireplace and chimney. While some wood burning fireplaces are approved for inserts, there are no gas fireplaces that are approved for an insert, and this is especially not the case with vent free appliances.

    By Chris from VA on October 26, 2015
    I am looking for wood burning fireplace inserts with outside air kits. What would you recommend?
    By Will M. on October 27, 2015

    So long as you have the ability to route the flexible ducting, many wood inserts will offer outside air kits. The Drolet Escape 1400 Wood Burning Fireplace Insert w/ Blower Included - DB03120 is one model that offers outside air.

    By Alecia from Cincinnati, OH on November 30, 2013
    I have been living in home for 3 years now. It has a gas fireplace insert. I have had a local gas company come out each year in the past to light the pilot. It does not seem to stay lit or is it normal for it to go out? They mention something about a new ignition. The heat was not effectively heating the room and I am seriously considering converting back to wood burning. What are your thoughts?
    By Collin C. - NFI Master Hearth Professional on December 2, 2013

    It is common for pilot lights to extinguish from time to time, especially if the chimney is prone to downdrafts. Reverting to wood burning is an option, but will not necessarily produce more heat. Utilizing a gas or wood burning insert, which use more controlled combustion techniques to generate heat, may be the best option. If you would like to provide the front width, rear width, height, and depth of your fireplace opening, I will be happy to suggest a few inserts that would work for you.

    By John from Cherokee, AL on January 11, 2015
    Can I add insulation to the outside of this unit to make sure that I do not catch something on fire? My walls inside and out are cypress. I need to make sure it does not get too hot.
    By eFireplaceStore on January 12, 2015

    As long as the back, bottom, top, and sides of the unit are installed maintaining the clearances that are specified in the manual, no additional insulation will need to be used around the fireplace. Adding insulation could actually stifle air flow and cause an overheat situation. The unit will be designed to maintain safe temperatures, as long as the clearances listed in the manual are maintained.

    By Lynda from Frederick, Maryland on October 23, 2013
    I recently purchased a home with a prefab fireplace that sits a foot off of the floor. I want to insert a large Buck woodstove. I'm seeking a second opinion because the company that I called has first said that the insert was too heavy for the prefab, but then has lifted the actual stove on the hearth and partially in the opening. Now the issue is that there is no clearance for him to connect the round flu liner that he made to the rectangular opening in the top of the stove that he has also made a boot for (boot is steel). He is saying he can't get in there to connect it. He is now trying to get me to buy another insert. I need another fireplace man, right? Can I have a Mason remove the bricks which would be covered by the flashing? It is sitting there now, but is it in fact too heavy? (approx weight is more than 300 lbs). It is a family insert about 30 years old, that has hardly been used. I am a single woman and just don't know who or what to trust.
    By Collin C. - NFI Master Hearth Professional on October 23, 2013

    To begin, most prefabs will specify in the owner's manual whether or not they can utilize an insert. Many prefab boxes are indeed too flimsy to support the weight of an insert. Even a relatively lightweight insert can crush the stamped steel floor easily. However, models that are designed to house an insert will have extra bracing that can allow it to deal with the weight.

    It seems to me that your installer did not do all of his homework before going through the trouble of fabricating an insert boot. Removing additional bricks above the fireplace would not help in this case, as the bricks are just a veneer and cannot make the fireplace opening any taller. The metal ceiling of the prefab unit is definitely the issue in this case. Unfortunately, a smaller insert would indeed be the only solution in this place, however some quick measurements taken by your installer could have verified this before he moved forward. The only other option would be to remove the existing prefab and replace it with a larger unit of the same brand that could house the insert. I apologize that I do not have a better solution.

    By NBellie from Phippsburg, MN on October 4, 2014
    Can a ventless fireplace insert be converted into a vented one?
    By eFireplaceStore on October 6, 2014

    Unfortunately, no. Vent free appliances are specifically tested and listed as such. They cannot be safely modified to a vented version, as the chassis of the unit may be compromised.

    By Nancy from Crystal Lake, IL on December 28, 2015
    I have a gas fireplace that doesn't throw out a lot of heat. Is there a metal insert or something that will throw the heat into the room?
    By Will M. on December 29, 2015

    If you have a gas log set installed into a masonry or prefabricated wood burning fireplace, there will be Firebacks for this.

    By Terry from Royalton, Ohio on September 13, 2014
    I have a Majestic M36 model fireplace and would like to install a wood burning insert into the existing box and vent threw existing double wall pipe, that would give me heat to the room that is 26 square foot by 25 square foot with a vaulted ceiling. Is there a insert that you can recommend?
    By eFireplaceStore on September 15, 2014

    Unfortunately, these early Majestic models were not tested and listed for use with a wood burning fireplace insert. Because of this, it is very possible that installation of an insert will subject the combustible framing around the unit to dangerous temperatures. The fireplace floor may also not be able to support the weight of an insert, as insert rated models usually have additional supports and gusseting.

    By Mark from Houston on March 4, 2014
    I have a 36 inch, 10 year old traditional natural gas fireplace. I am interested in increasing the efficiency of my fireplace. Would going to a vented fireplace be better?
    By Chris on March 4, 2014

    Direct vent fireplaces are the most popular type of fireplace. Direct vent units are the most efficient vented appliances on the market. Each unit is closed-combustion--enclosed with glass to seal it off from the room--and the coaxial (pipe-within-a-pipe) runs air in from outside for combustion while venting out the exhaust directly back out of the home. Direct vent fireplaces have a huge advantage over B-Vent and traditional wood burning models when it comes to the venting. Whereas a B-Vent or wood burning fireplace will require vertical venting all the way through your roof and at least three feet above, a direct vent unit offers flexibility and convenience. All direct vent appliances can be terminated horizontally, making it possible to place a unit on an outside wall and run just a few inches of pipe to the outside wall to complete your venting system. As such, almost all of our direct vent fireplaces have horizontal or through-the-wall vent kits that will include all the necessary components and take the stress out of building an expensive and complicated chimney system.

    If venting horizontally isn't an option, you can still build a vertical venting system with direct vent appliances. Direct vent pipe is cheaper than most class A chimney pipe, so it would still likely be more cost-effective to install a vertical venting system for a direct vent fireplace or stove than a wood burning unit.

    By Roderick Henderson from Texas on December 1, 2016
    I want to convert my wood burning fireplace to an electric. what options do I have?
    By Brennan W. on December 1, 2016

    You will need to remove the fireplace and replace it with an electric unit. What is the width and height of the opening in your wall?

    By Carla from Bourne, MA on September 3, 2014
    Can a gas fireplace insert be installed in a fireplace that has been capped in the second floor? Can we vent the gas fireplace insert downwards into the basement and out a side wall instead?

    By eFireplaceStore on September 3, 2014

    Unfortunately, no. While some of the larger direct vent fireplaces we offer have the option of a power vented exhaust, the inserts do not have this feature. The chimney would have to be extended with prefabricated vent piping or a vent free insert used instead.

    By Tate from Newaygo, MI on September 13, 2014
    I purchased a Drolet 1400 to put in my marble fireplace and I have a 22 foot chimney in the center of the house with only 3 feet exposed to the outside above roof. My masonry flue liner is 8 X 11 inches. Do I need to insulate the stainless liner or around the insert?
    By eFireplaceStore on September 15, 2014

    You are at the cutoff point between needing to insulate and not needing to insulate. Your chimney is not overly tall and the interior location are points in your favor, but the chimney liner is large enough and your climate is cold enough that insulating would be prudent. Even if the unit does draft without the insulation, it will not operate as efficiently as it could if the liner was wrapped. You will not need to insulate around the unit itself.

    I have removed a wood stove from my home, and will be building an area for fireplace in a new part of the house. I am not sure if it makes more sense to buy a fireplace insert, buy a wood insert or go the pellet route. I love the heat from burning wood but also want something that be efficient. The wood stove that we had was an older model that came with the house, and would heat a good portion of the house.
    By eFireplaceStore on December 16, 2016

    Pellet burning appliances are certain the most efficient type of solid fuel heater on the market, however the do require a good deal of regular maintenance to keep them operating at top efficiency. If weekly cleaning of the appliance is not a realistic match for your application, I recommend looking at a high efficiency wood burning fireplace instead. A popular seller of ours in this category is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace.

    I have a large Austin stone fireplace - gas logs and gas lighter by switch. Is there any way to replace with an insert so I can actually feel heat in the room and quiet the loud hissing of the gas?
    By Collin C. - NFI Master Hearth Professional on May 12, 2014

    It may indeed be an option to replace the current setup with a gas fireplace insert. Use of either a direct vent or vent free insert would greatly improve the overall efficiency.

    By Robert from Orlando, FL on September 20, 2014
    I'm looking for a natural gas fireplace insert, vent less and with a blower, with enough capacity to heat approx. 1000 square feet. I can't find anyone in central Florida that knows anything. My masonry fire box dimensions are approx. 30 1/2" wide; 25" high; and 23" deep (note flue is cracked). Can these devices be run continually in cold weather? What options and details should I be considering?

    By Kevin E. on September 21, 2014

    Per the area given and your location, a unit that is capable of producing about 30,000 BTU would be appropriate. Your fireplace is sized to fit something like our a href="">Empire Innsbrook. While vent free appliances are a great source of efficient heating, it is not a good idea to run them constantly. Extended use of a vent free appliance can lead to excessive moisture build up in the home. Additionally, as these units pull their combustion air from the room, excessive burn times necessitate that a window be opened in the home to allow for recovery of make up air. Additionally, it would be wise to check with your local code enforcement to confirm that vent free appliances are permitted in your area. Some jurisdiction prohibit the installation of these products.

    I'm getting a new house with a ventless fireplace insert. Can we put the fire glass pieces in it without a problem?
    By Will M. on January 5, 2016

    Media like fire glass or stones will be listed for use with the vent free appliance of your choosing and you will only be able to use media of this type if the product literature for the vent free system of your choosing has been tested with glass media. Fire glass burners are configured differently to accept fire glass and using this decorative material in a vent free system that cannot use glass media will likely result in unsafe operation.

    By Simon from NJ on October 28, 2014
    I have a fireplace that is 42 inches wide and 30 inches high with plenty of depth. What product, for a wood burning insert, would best fit my dimensions as well as maximize the glass window?
    By eFireplaceStore on October 28, 2014

    Ideally, the Osburn 2400 High Efficiency EPA Woodburning Insert with Blower would be used. Another option would be the Napoleon EPA Wood Burning Fireplace Insert - EPI-1402, as it also features a relatively large firebox and an efficient hearth stove design.

    By Harry McCord from Newport News, VA on January 12, 2017
    Do you have a fireplace insert that would fit my open sided (right) fireplace. I have natural gas available, although I am burning wood in it currently. I would like to convert it to a natural gas unit. (See pictures below) Dimensions: 34" by 22" deep, by 30" high.
    By Brennan W. on January 12, 2017

    Unfortunately, we have no inserts that can be installed in such a configuration.

    By Matt from Grand Rapids, MI on October 17, 2013
    I have partially removed a zero clearance wood burning fireplace that came with my modular home. Is there a direct vent wood insert that I can put in the current opening and vent out of the side of my house, or use my current metal chimney system? I'm looking for a more economic idea for an alternate heat source. Would a direct vent natural gas insert work, too?
    By Collin C. - NFI Master Hearth Professional on October 17, 2013

    It will likely be best to use a self contained wood burning fireplace to go in place of your current unit. An insert could not be used in the opening, as the remainder of the zero clearance fireplace would not insulate properly.

    By Aisha from Atlanta, GA on September 15, 2013
    I have a double sided fireplace which uses propane. I would like to move it to a corner in the living room. Can the fireplace be converted to fit in the corner, or would I need to purchase a whole new corner unit?
    By Collin C. - NFI Master Hearth Professional on September 16, 2013

    Unfortunately, the unit would not be able to be converted to this application. A single sided fireplace would need to be obtained and framed into a corner enclosure.

    By Steve from San Jose, CA on November 23, 2015
    Will the Empire Innsbrook Medium Direct Vent Gas Fireplace Insert DV33IN33LN be a good selection for a fireplace located in a 375 to 400 square foot room? To control the room temperature, when you use a FRBTC Remote with Thermostat control, does the fireplace (flame) turn on and off or does the blower just reduce speed?
    By Will M. on November 24, 2015

    Please note that the product in question is a fireplace insert, meaning that an existing masonry or prefabricating wood burning fireplace is required to install this appliance. However, this insert has a BTU input of 33,000 with 77% efficiency. To heat the space you have described, you will only need around 14,000 BTUs. Like all millivolt valves, the thermostatic remote would simply turn the burner flame off and on, depending on the temperature and the blower would operate independently.

    By Bill from Hollisgton, MA on September 23, 2013
    How would you install the insert into an existing fireplace? What kind of liner is required?
    By Collin C. - NFI Master Hearth Professional on September 24, 2013

    Wood burning and gas inserts alike will usually use a decorative metal surround to cover any additional space between the insert and the fireplace opening. The insert would simply be pushed into position, then the liner can be dropped down the chimney flue. Lastly, the surround can be attached. Are you considering installation of a gas or wood burning insert? What is the approximate height of your chimney? Please advise at your convenience.

    I need to get the direct vent pipes to connect my Monessen 33CFDV Patriot 33" Rear/Top Direct Vent Fireplace with Millivolt Pilot, CUI-33CFDVNVSB, Propane. Could you tell me what venting I need to order? I prefer twist lock.
    By Will M. on January 5, 2016

    For accuracy, please answer the questions asked on our Chimney Pipe Design & Quote Form and you will receive a comprehensive list of components required for installation.

    What is the difference between vent and ventless insert? Also, which one is better, electric or gas inserts?
    By Will M. on July 5, 2016

    There is a wealth of information available here that should answer any questions regarding vented vs. vent free inserts.

    When deciding between electric vs. gas, the primary concern should be heating capacity as electric fireplaces and inserts are limited to 5,000 Btu. Another concern will be the aesthetics of an electric fireplace when compared to gas as only the higher end electric inserts will offer a comparable flame. The advantage of an electric fireplace will be the ease and cost of installation. Aside from potentially having to hire an electrician to provide power if it is not currently located where the fireplace is to be installed, you will not need to hire a licensed plumber or gas fitter to perform the installation.

    By Trent from Fountain Valley, CA on October 18, 2013
    I am renovating my house. I want to install a gas fireplace insert in my living room fireplace with a blower. I am interested in the natural gas Innsbrook Medium Direct Vent model DV-33IN-33LN. My question is concerning the electrical wiring for the blower. Do I need to protect the electrical wiring from heat? Is there specific heat resistant wiring and a junction box that needs to used? Does the junction box house a regular electrical outlet? Where should I place the junction box? My contractor is willing to run the electrical wiring into the fireplace for me, but he has never done it before. Can you advise?
    By Collin C. - NFI Master Hearth Professional on October 18, 2013

    Because the electrical outlet is to be located outside of the insert chassis, within the fireplace, you do not have to use shielded or high temperature jacketed wiring. Standard copper wire can be used, although a metal single gang junction box is recommended. A standard electrical outlet can be used. The box is best located on the rear, right of the fireplace, as you face the opening.

    By Sheila from Paducah, KY on December 16, 2012
    Do you have to run the blower on a wood-burning fireplace insert all the time? I didn't know if they would get too hot if you turn the blower off. Would the blower pull a lot of electricity? Is that listed on the fireplace or is that provided?
    By Collin C. - NFI Master Hearth Professional on December 17, 2012

    For the fireplace inserts that we sell, and most other models that are available, it is not necessary to run the blower. The blower is simply an accessory that can be used to heat a room more rapidly or extend the reach of the insert while it is being burned.

    Most blowers will only draw 1-2 amps while running. This amperage information will be listed on a build plate that is attached to the blower, but is generally not provided with the manufacturer information.

    By Jack from Vncouver, WA on February 22, 2014
    I have what I believe is a model QVI30 gas insert on propane and I'm trying to replace the thermocoupler. Not sure how to disconnect from the valve. Does it loosen clockwise or anticlockwise? Could it be held in place with a locking screw?

    By Collin C. - NFI Master Hearth Professional on February 24, 2014

    While we are not a Quadra-Fire dealer, almost all manufacturers use a 1/4 inch flare nut to secure the thermocouple lead to the valve. Because of the heat and cool cycles, this nut can seize in place, and a flare nut wrench will be needed to avoid stripping the nut. The nut uses standard threading and should be turned counterclockwise to loosen it.

    By Bill from Northport, NY on September 21, 2014
    I'm looking for a fireplace insert to burn wood. What is the difference in manufacturers? How do I know which is the best?
    By eFireplaceStore on September 22, 2014

    The particular brands of insert we carry are all of comparable high quality, save for the US Stove Medium EPA-Certified Wood-Burning Fireplace Insert, which is more of a basic, budget model. The Napoleon series offers some more contemporary models and a great warranty, however Drolet, Osburn, and Flame are all manufactured by SBI and are very well built as well. In these cases, it boils down to looks and capacity of the firebox.

    By Rodner from Abilene, TX on December 30, 2016
    Do you have gas radiating inserts with logs to go in a fireplace that is already wired for gas?

    By Owen on December 30, 2016

    We do. You can find a great selection Here.

    By Alan from Wisconsin on February 23, 2014
    We have just purchased a home built in 1994. It has a Heatilator with two small blowers and glass doors. It makes little heat and I would like to put a different insert in that actually makes heat. There is no masonry firebox. The dealer said we were out of luck and would have to put in a gas fireplace or start over. Is this true? I have no interest in a gas fireplace.
    By Collin C. - NFI Master Hearth Professional on February 24, 2014

    Depending on the model of the Heatilator, it may be listed and sized to accept a slide in wood burning insert. These types of appliances are sealed and feature a more powerful blower assembly for increased heating ability. If you would like to provide the model number of the appliance, I will be happy to check into this option.

    By Richard from Poulsbo, WA on December 7, 2012
    Can you use a grate in a wood-burning fireplace insert?
    By Tyler M. - Fireplace Specialist on December 7, 2012

    This will depend on the manufacturer and model of the insert in question. Some inserts allow for the use of a grate, but it is usually included as part of the insert itself, while most do not include a grate and clearly state not to use one. Please check your owner's manual to see if a grate is permitted.

    By Anthony from Carmel, California on November 4, 2013
    If my fireplace insert has a flue going up and out the existing chimney, can I cover the rest of the space in the existing chimney with sheet metal to make more heat be directed back into the house? Right now it's like a wind tunnel sucking the heat right back out.
    By Collin C. - NFI Master Hearth Professional on November 5, 2013

    If the fireplace insert has a dedicated liner that is smaller than the actual chimney flue, you can indeed cover the space around the liner with sheet metal or pack it with pieces of rolled, unfaced fiberglass insulation. This will help to eliminate the overdrawing of air from the room.

    By Jane Collins from Jupiter, FL on February 11, 2013
    Do ventless fireplaces burn propane?

    By Tyler M. - Fireplace Specialist on February 11, 2013

    Vent-free and ventless gas appliances are made for either natural gas or propane. These are not interchangeable, and since the units cannot be field-converted, care must be taken to ensure the proper fuel type is selected.

    By Mark from Springfield IL on January 18, 2014
    We have a very small fireplace. 19" wide in back, 20 1/2" wide in front, and 9" deep. Would you have anything that would fit something that size?
    By Collin C. - NFI Master Hearth Professional on January 20, 2014

    Unfortunately, we do not offer any fireplace inserts that can accommodate the small dimensions of your fireplace opening. Usually, openings this small where originally constructed as coal burning fireplaces. However, even our replica coal burning baskets are not able to accommodate the shallow depth. I apologize that I do not carry any items for your needs.

    By Ceil from FL on March 22, 2013
    Do any of your inserts come with a way to catch ashes so that removal is easier?
    By Collin C. - NFI Master Hearth Professional on March 25, 2013

    Unfortunately, the fireplace inserts that we offer do not have an option for an ash pan or tray. Ashes must be raked or swept to the front of the unit and removed using a handheld ash pan. This is one disadvantage to an insert over a free standing stove.

    By Ddoug from Oregon on November 15, 2016
    Do you have inserts for two sided fireplaces?

    By Tyler from New Brunswick on September 5, 2013
    I'm wondering what options are out there for a wood burning insert that needs access to the electrical behind the stone. I'm a mason and I'm curious if there are any access panels that look nice and won't stand out.
    By Collin C. - NFI Master Hearth Professional on September 5, 2013

    Our wood burning inserts that are equipped with blowers will usually utilize a junction box that is mounted within the fireplace cavity itself. The electrical cord that is supplied with the insert would then plug into the mounted box, which would be concealed behind the surround flashing.

    By Ken from Kansas City, Kansas on February 23, 2014
    I am interested in purchasing the Timberwolf EPI22, but I need to make sure the flashing will cover an area of 29"H x 42"W. Is this possible?
    By Collin C. - NFI Master Hearth Professional on February 24, 2014

    The included flashing for this unit will indeed cover an area of up to 32 inches in height and 44 inches in width.

    I have a Superior direct vent fireplace in my bedroom. The pilot is the type with a gas knob and a red striker button. It has never worked properly and consistently since it was put in in 1994. Do I need to have the tile and mantle removed to put in a new fireplace, or can the logs, burner platform etc (the guts) be removed and a new fireplace fit in?
    By Collin C. - NFI Master Hearth Professional on December 31, 2012

    Unfortunately, most direct vent fireplaces are not manufactured so that the internal engine (burner, valve, electronics) can be replaced while utilizing the same chassis. Each fireplace is made as a complete system and must be replaced with an entirely new unit.

    Some newer models are upgradeable, but this is a recent development and was not the case for Superior fireplaces. I would recommend having the unit removed, then taking measurements of the wooden frame the unit was built into. Once you have these framing dimensions, you can closely match a replacement unit that will keep you from having to completely redo the opening.

    By Wes from Lakewood, CA on July 16, 2013
    We are buying a home with a gas burning fireplace that has a chimney. Can we convert it into a wood burning, natural fireplace?
    By Tyler M. - NFI Certified Specialist on July 17, 2013

    No, you would need to replace the entire fireplace and chimney in order to burn wood. You can see our full selection of zero-clearance woodburning fireplaces below:

    By J.W. from IL on April 29, 2015
    In selecting a direct vent insert to convert our gas-ignited, wood-burning, masonry fireplace to gas-only, do we need to select the largest insert that will fit? Can we select a size or two smaller, assuming we are willing to install the right facing to cover the gap between the insert and the original firebox?

    By Brennan W. on April 29, 2015

    So long as you select a facing that will cover the area between the insert and the masonry opening, there should be no problem with sizing down on an insert.

    By Leanne from Calgary, Alberta on November 22, 2012
    Do you sell any fireplace inserts that can common vent through the chimney that my furnace vents to? We have an existing ornamental masonry "fireplace," in the basement which is not a real fireplace. It has only ever had a flickering light bulb in it, but is made of brick with a nice arch in it. It backs onto the furnace room, with easy access to the gas line and furnace chimney, so we are hoping to find something that will work with that chimney if the insert is approved to vent that way.

    The other option is the ventless insert, which makes me a little nervous because of oxygen consumption in the basement.
    By Collin C. - NFI Master Hearth Professional on November 23, 2012

    We do carry several gas fireplace inserts that can share the same chimney as other appliances. However, both flues of the gas appliances would need to have a liner running the entire length of the chimney. If both appliances were vented into the same chimney without a liner, back drafting and turbulence in the chimney can result and cause undesired operation of the insert.

    By Susan from South Bend, Indiana on January 4, 2014
    We have a woodburning fireplace currently and the dimensions are as follows: Front width 36", front opening height 24", depth from front to back 18", and back width is 23". We are looking for a ventless, gas insert with a blower. My main purpose for this conversion is to be able to use this gas insert when we lose electrical power. Will we be able to use the fireplace during a power outage, and will it supply adequate heat? Will the blower work off a battery or does it only work on electric? If the blower does not work in a power outage, will the insert give off enough heat to heat a small room? Do we have to run electricity to the blower? Which model do you recommend based on my information?
    By Collin C. - NFI Master Hearth Professional on January 6, 2014

    A popular and well built model that we carry is the Medium Innsbrook Vent-Free Gas Fireplace Insert with Built- In Thermostat. This unit would be able to heat approximately 700 square feet on its own, with the blower increasing thermal efficiency enough to extend the reach to 850 square feet when operating.

    This unit uses a millivolt gas valve, meaning that it produces its own electricity and could work in a power outage. Unfortunately, the blower requires a 120 volt power source to operate and cannot run on a backup battery.

    By Steve from Sacramento, CA on November 8, 2012
    Typically, how do you clean the glass on a gas fireplace? How do you get to the inside?
    By Collin C. - NFI Master Hearth Professional on November 9, 2012

    In most cases, direct vent and some sealed B-vent fireplaces will have metal clasps or screw clasps that will hold the glass in place. Depending on your unit, the clasps may be on the top, bottom, or upper and lower sides. Usually, top and bottom types will only have 2 clasps, which will allow the glass to tilt up or down when opened. Side clasp models typically have 4 clasps that will all need to be opened to allow you to pull the glass straight off when opened.

    By Bobby from Zebulon, NC on December 17, 2012
    We have a Dare IV fireplace insert. It runs on high all the time, which makes it noisy when trying to watch TV. Do you know where we may get a fan motor switch? The insert has two fans, both having the following information: 115 v 50/60 Hz A 1.16/1.02.
    By Collin C. - NFI Master Hearth Professional on December 18, 2012

    We offer a universal blower temperature switch that could be used with your existing blower assemblies. The Hearth Products Controls BSK Blower Sensor Kit is designed to modulate the operation of your fans based on the temperature of the firebox.

    By J from Racine, WI on October 30, 2013
    I'm looking for a gas fireplace insert with a back vent. Does this exist?

    By Collin C. - NFI Master Hearth Professional on October 30, 2013

    Unfortunately, the gas fireplace inserts we carry are top vent only. This is almost always the case, as a rear vent will take additional space within the masonry fireplace and make installation more difficult.

    By Joe from Ventura, CA on November 21, 2013
    I have a 27 1/2" H x 36" W fireplace with a natural gas flame pipe in it. No matter what I burn in it, barring a roaring fire, no useful heat is generated. Is there an insert that would help heat a 27' X 15' room with any degree of efficiency? The fireplace is at the end of the 27' dimension.
    By Chris on November 21, 2013

    A fireplace insert would be a great way to significantly increase the efficiency of your existing fireplace. Are you looking to use a wood burning insert, or a gas insert? This will greatly narrow the search results and recommendations.

    By Randy from Idaho Falls on September 6, 2013
    I purchased a 42 inch Alpine Tahoe premium insert and have it almost set up. However, I noticed that there are only 110V lines running through the controls. I want to hook up a thermostat which is usually lower voltage. What do I need on this unit to hook up a thermostat?
    By Collin C. - NFI Master Hearth Professional on September 6, 2013

    Depending on the control system your Tahoe uses, a specific 110 volt thermostat may be needed. Other models utilize a low voltage transformer. Please advise as to the exact model number of the fireplace and I will be happy to check into this further. The model number can be found on the build tag in the bottom of the unit.

    By Davi from BC, Canada on June 8, 2014
    I have a "Zero Clearance" Metal fireplace in my house (built in 1970's) that sucks the heat out of my house. I have been told that these types of fireplaces are not designed for the type of heat generated by modern inserts. It has been suggested that the metal insert is attached to wood framing and a stucco exterior. I have attached some photos and rough dimensions of the fireplace. The fireplace is located upstairs (~1200 sq ft, ~2400 sq ft in whole house upstairs and down). What is the best option for getting some more efficient wood heat coming out of here? Do I need to modify the firebox (ie. remove metal box, add firebrick panels, etc) before I put in a chimney liner and insert? I am located in Canada, with average minimum temperatures around -10 C (14 F).
    By eFireplaceStore on June 9, 2014

    Most prefabricated fireplaces are indeed not able to handle the heat that is generated by a closed combustion fireplace insert. Also as suggested, they are usually enclosed and anchored to adjacent 2x4 or 2x6 wood framing. The raised hearth floor and deeply recessed installation of the current unit would also make installation of an insert difficult. Your best option will likely be the complete removal of the current unit and chimney. You can then retrofit a high efficiency model in place of what is there now. Before we proceed further, is it an option for you to resize the fireplace opening to fit a different model or are you fairly set on the opening size? Please advise at your convenience.

    By Steve from Breward, FL on January 19, 2015
    I am doing some construction on a home with a large back porch where we will be installing a wood burning fireplace. It is a covered porch and the fireplace will not be subjected to water. Do I need a stainless steel fireplace insert or a regular steel insert?
    By eFireplaceStore on January 20, 2015

    By code, a stainless firebox should be installed in any outdoor application that will expose the unit directly to outdoor air. Even if covered, the humidity in the air will quickly corrode a standard sheet metal firebox, requiring it to be replaced within 5 to 8 years on average.

    How do you measure a fireplace to purchase a replacement? I have what looks exactly like your FMI Bungalow Builder Circulating Woodburning Fireplace. Do I measure it diagonally -- like a TV -- or just across the bottom?
    By Collin C. - NFI Master Hearth Professional on April 29, 2014

    Sizing for fireplaces is taken by measuring straight across the opening of the unit. However, it can be difficult to determine just how large the existing fireplace is, as most of the chassis is hidden within the wall. If there is a build tag or sticker anywhere on the unit, it should give a manufacturer name and model number, which will allow me to research full dimensions of the unit. This plate is typically just inside the fireplace opening, across the metal smoke shelf at the top of the opening, or in the bottom of the unit.

    What portion of the dimensions of a fireplace does "shop by size" refer to?
    By eFireplaceStore on December 5, 2016

    The "shop by size" feature is in reference to the width of the fireplace insert itself.

    By Doug from Woodville, TX on February 27, 2015
    We're interested in a fireplace insert. We have a 1968 house which has an old Superior Heatform Model A fireplace. Is it possible to replace this fireplace with an insert? The original fireplace has a brick chimney. Would we have to completely remove this old fireplace? Also, would we have to remove the chimney and replace it?
    By eFireplaceStore on February 27, 2015

    I have come across many of these heat exchange type firebox "sleeves" and in almost all cases, the brick firebox behind them was not finished to accept an insert. However, the only way to know for certain is to first remove the existing unit and inspect the interior of the firebox to ensure it was lined with firebrick and the chimney has a metal liner or clay flue in good working order.

    By Norman from Washington , DC on December 13, 2016
    I have a coal fire place that has not been used before bought my house.How do I convert it to wood burning? I know with electric, I could just put a insert. How much heat does an electric fireplace give off or is mostly for show?
    By Will M. on December 13, 2016

    In order to burn wood in this fireplace, it will need to be inspected for safe operation. For this, we recommend using the Chimney Safety Institute's website to locate a certified chimney sweep in your area.

    To answer your question regarding electric hearth systems, they will produce heat but are limited to around 5000 btus. This will heat a space of approximately 143 square feet.

    I have a wood burning insert which we added a gas log set to except the gas log produces little to no heat as everything goes right up the metal chimney. I thought you didn't recommend putting a vented gas insert into a wood burning insert but I'm not sure as to why. We currently have a 9 inch ID metal pipe going up to the cap. Couldn't you put a gas insert into the wood insert and run the dual 3 inch lines up the 9 inch metal chimney?
    By eFireplaceStore on September 16, 2014

    As long as the fireplace in question is large enough and has been listed for use with a gas insert, you certainly could install one. The most common problem is finding an insert that is short enough to fit a prefabricated wood burning fireplace. Another common issue is finding an insert that has the 3 inch inlet and exhaust collars that line up with the exhaust collar on the fireplace. In many cases, one collar is too far forward or too far back, preventing you from routing one of the 3 inch liners properly.

    I have a Majestic Insta Flame natural gas fireplace. Model: DVR36 RP. Serial #: B11B0097092094. BTUH appears to be 18,299. I need a replacement fireplace insert for the upper center panel. Can this be ordered individually or do the inserts come in a set?

    Why does the glass in the door of our woodburning fireplace insert turn black and smoke over? We are burning seasoned wood and I recently vacuumed the catalytic business.
    By Will M. on December 1, 2015

    It could be that the wood is "too seasoned" (rotted) or that there is a leaking gasket in the door. If this is a wood insert, replacing the gasket or adjusting the door will be the best option and the literature for your insert will provide these instructions. If the wood is rotted, the cordwood should be stacked off the ground and covered with a tarp. Splitting the wood will reveal if it is rotted, but rotted wood will also smoke and show sooting on the glass rather quickly. You can wet newspaper and dip the wetted portion into the ash from your last fire to clean the glass quite effectively. After this, burning wood that is confirmed to be seasoned and not rotted or wet should not soot the glass. If this happens, a door adjustment or gasket replacement is in order. Also, investing in a Moisture Meter is always a good idea.

    Can I replace my gas insert with a pellet burning one?
    By eFireplaceStore on November 17, 2014

    As long as your fireplace has the dimensions to house a pellet insert, installation of one should not be a problem. Pellet inserts use a different venting system than gas models. As such, the existing venting will need to be removed and a stainless liner installed for the pellet insert.

    Is this item gas or electric?

    I have a wood fireplace that I would like to put an electric insert into. The opening is 37" W x 27" H. What size of electric insert do I need to fill that? Also, would it need a surround?
    By Chris C. on October 15, 2015

    I would suggest the Dimplex DFI2310 Deluxe 23" Electric Fireplace Insert to be paired with the Dimplex DFI23TRIMX Expandable Trim Kit for DFI2309 and DFI2310 to cover the spacing left from the insert to the existing fireplace facing.

    I have a tempco TBF 36 3 fireplace. Can I use an insert?
    By Collin C. - NFI Master Hearth Professional on November 27, 2013

    After reviewing the original literature for this unit, there is no mention made of using a fireplace insert. When this is the case, by default, an insert should not be installed into a manufactured fireplace that is not specifically listed for use with one.

    By Kelly from Moore, SC on December 27, 2013
    What size exhaust pipe do you use with a 42" wood burning fireplace insert?
    By Collin C. - NFI Master Hearth Professional on December 27, 2013

    The size of the Class A pipe used with a 42 inch manufactured fireplace will depend on the exact manufacturer and model number. It is fairly standard for an 8 inch chimney system to be used, although I have seen systems as large as 12 inches as well. If you are able to provide the manufacturer information, I will be happy to check into what may work with the unit.

    What are the four top-rated brands for producing heat? What is the recommended BTU for quality heat?
    By Tyler M. - Fireplace Specialist on December 19, 2012

    Our top brands include Napoleon (wood and gas), Monessen (wood and gas), Majestic (wood and gas), FMI (wood and gas), Empire (gas), and Vantage Hearth (wood and gas). A general rule of thumb for BTUs and heating area is 35 BTUs per square foot, or 35,000 BTUs for 1,000 square feet. Much will depend on the layout of the home, its insulation, etc.

    By Richard from Lake Ariel, PA on October 26, 2013
    We have a ventless gas log propane insert now. For the last year it has been producing a sooty film on the walls. There is also an odor (not of a gas leak) that is noticeable when you come in from outside. We need it for heat, not just decoration. Do you think we need a new one, or should we try a vented wall unit?

    By Collin C. - NFI Master Hearth Professional on October 28, 2013

    If the ventless insert has not been serviced recently, I highly recommend having the unit evaluated by a service technician. Vent free gas logs and inserts rely on the air within the room for combustion. As such, they can draw in dust and dirt from the room over time, which will cause clogging of the air shutter. This can lead to release of odors, poor flame pattern, and staining of walls.

    Do you sell a wood burning fireplace insert with two doors that open fully?
    By eFireplaceStore on October 2, 2014

    Unfortunately, no. The units we carry use a single door. Most manufacturers have largely steered away from the double door models. This is due to the modern EPA units being smaller and the fact that double doors offer more opportunity for smoke leakage.

    I am a home designer and I have an application where i would like to put a 36" wide x 12" - 18" deep, see-thru gas f/p between a master bedroom and a jetted tub. I need to be no more than 4" from an outside wall and the overall framing from face of outside wall to end of framing is 44". can you help me?
    By eFireplaceStore on May 22, 2014

    I believe the Empire Tahoe Premium Direct Vent Natural Gas See-Thru Fireplace - 36" will be the best choice for your application, but before we proceed further, I would like to clarify a bit of information about the installation. In regards to the facing of the outside wall, are you referring to the inside facing, as in the drywall surface? Please advise at your convenience. Also, most of the see through models we offer are 24 inches in width or very close to it. Will the extra width be allowable for this application?

    If you install a wood burning insert, can you safely mount a TV above it or will the heat damage the TV?
    By Will M. on November 9, 2015

    So long as the television is installed per the mantel clearances outlined in the installation manual for the insert you have chosen, the television should be safe, however, I highly recommend installing a mantel at the required height and then installing the television above the mantel.

    I have an existing double sided fireplace. I would like to get an insert to fit inside, and utilize the chimney for real wood burning, or pellet. Do you have anything that does not require demolishing the hearth to fit in (less than 30" high)?

    By Damien from Savannah, GA on November 8, 2014
    Can your models of direct vent gas fireplace inserts fit an existing fireplace opening? My opening is 26-1/4" tall, 25-1/8 wide at the top of the opening, 26" wide at the bottom of the opening, 16-1/2 inches deep at the top, 19" deep at the bottom, and 24" wide at the back.
    By eFireplaceStore on November 10, 2014

    Because of the small size of your fireplace opening, you will need to utilize one of our smallest fireplace inserts. This unit is the Napoleon GDIZC Direct Vent Gas Fireplace Insert. This model is specifically designed to fit small masonry and prefabricated fireplaces, while still providing a substantial BTU output for the size.

    By Scott Borton from Aurora, IL on February 27, 2013
    I have an existing wood burning fireplace and I would like to install a ventless gas insert. My existing opening measures 36" wide at front, 23" in back, the existing height is 20 1/4" and the depth is 24". Do you have an insert that would fit these dimensions?
    By Tyler M. - Fireplace Specialist on February 27, 2013

    I have an older, 4 foot firebox insert and the damper is not closing completely on one side. Do you have any idea what could be causing this problem?
    By eFireplaceStore on December 8, 2014

    There is potential for buildup of hardened creosote or corrosion of the damper throat to hold the damper plate open. I recommend having the damper and chimney inspected by a chimney sweep to confirm the issue and rectify it.

    By Mark Farrell from Pasadena, MD on November 4, 2012
    I recently purchased a home with a fireplace that says Majestic. I see MBUC 36 and a V 762283.

    This unit has a blower motor under the firebox with a rod that pulls out and in and left or right. I presume this is a vent of some sort for circulating? It looks to me that you unscrew the left and right walls at top middle and then lift bottom of firebox to get to the bottom?
    By Collin C. - NFI Master Hearth Professional on November 5, 2012

    The control rod you mention is likely meant to open and close the outside air inlet for combustion. If there is an air inlet on the exterior of the home near the fireplace, this is definitely the case.

    You should indeed be able to access the blower area by removing the floor panel. Many units have an access panel in the floor that prevents you from having to remove the entire panel, but the manual for this unit does not specify.

    By Kim from Hampshire, IL on December 31, 2014
    Can a fireback be used in a fireplace insert?
    By eFireplaceStore on December 31, 2014

    It is not recommended to do so. The high heat generated in a fireplace insert can warp and damage the casting, as a fireplace insert will not have the dilution air pulled in that an open fireplace will.

    By Juanita from El Paso, TX on July 13, 2017
    What is the difference between an insert and a fireplace?
    By eFireplaceStore on July 13, 2017

    An insert or fireplace insert refers to a type of appliance that is designed to be installed into an existing masonry fireplace opening. As you may know, an open masonry fireplace insulates well against heat transfer to adjacent walls, but it not efficient at heating a home. A fireplace insert can be a wood or gas appliance, but both will be much more efficient at heating your space. Inserts do not have a heavily insulated outer jacket and rely on the masonry fireplace walls for proper insulation and safety. Inserts utilize a metal flashing or surround to cover the remaining space between the insert and the edges of the fireplace opening. They also rely on flexible flue liners for proper venting up the chimney flue. A prefabricated fireplace is a fully self-contained appliance that is built with the intention of installation into a combustible wall opening. As such, the appliance can be enclosed within a combustible mantel or dimensional lumber framing. Operation is similar to an insert, but the additional outer air layer and metal jacket is what ensures safe operation within a combustible wall. These types of appliances also use rigid vent pipe. For additional elaboration on fireplace inserts, please visit our fireplace insert guide.

    Why Buy a Fireplace Insert?

    Although you may enjoy your old fashioned fireplace, these are very inefficient for heating a room, instead heating the bricks and outside air. Considering the time it takes to build and maintain the fire, you may want to look for a more user-friendly option. The answer to your problem is a fireplace insert! At, we offer many options to fit your needs and home decor. Purchase one of our fireplace inserts to enjoy a lovely fire without the hassle and contamination caused by a traditional masonry fireplace.

    Insert Essentials and Styles:

    Regardless of style and fuel type, all fireplace inserts are essentially the same: a fireproof metal box that contains the heat. Electrically powered fireplaces are perhaps the most convenient, requiring no venting or special expertise to install. You can enjoy the simulated flames with or without heat to create a nice, relaxing atmosphere. Another style that is gaining popularity is the gas insert. Although these require professional installation and sometimes an external vent, they are the most cost-effective fireplaces for heating a room. Some can even be wired to the thermostat in a zone-heated home, helping to keep your gas bill lower!

    Perhaps the most popular style is the wood burning fireplace. This insert is for those who love the sensory delights of handling the firewood, coaxing the flames with kindling, and the sound and smell of a campfire. You will need to keep your chimney free from debris and dispose of the ashes, but it's no more work than maintaining your traditional masonry fireplace and chimney.
