    How do I know what size to get? Do I measure the front opening? The back width? The depth? The height?
    By Brennan W. on October 12, 2016

    To determine size, you will need the front width, rear width, depth, and height, as well as whether you will be using natural gas or propane. From there, we can assist you.

    We are looking to install a natural gas insert into the current wood burning fireplace in the living room. The dimensions are 32"H X 37"W X 16"D (but the Depth could be 20" because it is inset 4"). What insert should I purchase and what if any trim kits will I need?
    By eFireplaceStore on September 2, 2014

    Based on the dimensions, you could use one of our best selling models, which is the Empire Innsbrook Large Direct Vent Gas Fireplace Insert - Natural Gas. This model has an excellent track record as a reliable and efficient supplemental heat source. Empire has been in the business of manufacturing direct vent heaters for decades and this model has long been a staple of this product line. The required trim for this model to fit properly in your opening is the Empire Contemporary Black Steel Fireplace Insert Surround - For Large Innsbrook Fireplace Inserts.

    What exactly do I measure to determine the right size gas fireplace for my wood burning fireplace?
    By Will M. on October 21, 2016

    While many gas insert manufacturers only request the front width, rear width, height, and depth, I highly suggest measuring the front height and rear height as well, as most all masonry will have a shallow depth at the top of the opening that slopes towards the back wall. Without factoring this in, customers may receive an insert that will not push all the way into the fireplace opening. This is more of an issue with wood burning inserts, but it is always better to be certain prior to ordering. Also, more detailed minimum hearth requirements are provided in the installation manual for each insert.

    By maria from Missouri on November 16, 2012

    By Collin C. - NFI Master Hearth Professional on November 19, 2012

    We are an independent online retailer and sell several brands of gas fireplace inserts. As such, I will require the manufacturer's name and model number of the fireplace in order to provide the proper lighting instructions.

    Most units will have a build plate near the gas valve which will have the model information.

    Is there significant difference in performance between vented and non-vented gas inserts?
    By Will M. on April 19, 2017

    While there theoretically would be no difference between vented vs. vent free with proper installation and maintenance, ventless systems are subject to requiring additional care due to the oxygen depletion sensor and the fact that any unburned byproducts of combustion will simply burn off into the home and not through the chimney system. If the ODS becomes clogged and/or the gas controls are dirty, you will experience operational issues with both the pilot and burner. Of course, these issues are prevented with proper maintenance and cleaning.

    I will also note that there will be eventual issues with any ventless log set purchased with ceramic fiber logs as this material will eventually break down, requiring replacement of the logs themselves. If you do choose to purchase a ventless log set, I highly recommend selecting a log set with solid refractory ceramic construction as these logs will last a lifetime.

    Unfortunately, Superior is no longer in business and we were not a dealer for them. As such, we do not stock this component. Universal panels are available that can be cut to fit. An example is the Hargrove Replacement Fireplace Refractory Panel - 24 inch X 28 inch. The only other option would be to contact a Superior dealer, now Lennox Hearth Products, to see if they may still have the original part on hand.

    By Stan Collins from Eastman, GA on November 26, 2012
    What advantage is there between a gas (ventless/propane) fireplace insert versus ventless gas logs? I have a real fireplace with flue tile (damper on top of chimney). Will the insert help cut further loss of heat escaping from the room?

    I am presently in the market for a replacement for propane gas logs that I've had for years. I am extremely interested in the electronic remote that allows you to not use the pilot light.
    By Collin C. - NFI Master Hearth Professional on November 27, 2012

    A ventless gas fireplace insert will hold an efficiency advantage over gas logs for a couple of reasons. First, the insert is completely sealed. As you mention, this will prevent any heat from the room escaping up the chimney and will ensure all heat produced by the unit will enter the room.

    Second, you can equip the insert with a circulating fan, which will help to speed heating of the immediate area. The only downside to the inserts we carry is that they all use a standing pilot as opposed to the ventless logs that have an option for electronic ignition.

    By Stephanie from Seattle, WA on October 28, 2016
    Can you clarify the difference between vent vs. vent-free?
    By Brennan W. on October 28, 2016

    The difference between vented and vent free are that a vent free unit operates at a level of efficiency which allows it to draw combustion air and exhaust into the room, but a vented unit will need venting to remove exhaust and draw in air. These units can be installed by a general contractor or plumber.

    By Collin C. - NFI Master Hearth Professional on January 7, 2014

    Gas insert installation differs by area, but it is common for gas plumbers or HVAC technicians to install this sort of unit. The gas insert itself will come with an integral burner and log assembly. As such, existing logs could not be used again.

    Also, please advise if your existing fireplace is a brick/masonry unit or a manufactured (metal) unit. For more information, please see our Fireplace Insert Buying Guide.

    Which gas insert fireplaces support horizontal venting?
    By Tyler M. - NFI Certified Specialist on December 19, 2013

    None of the gas fireplace inserts, which are intended for installation inside an existing fireplace and vent up through an existing noncombustible chimney, can utilize horizontal venting. However, if you are looking for a direct vent fireplace that will be installed in its own enclosure, these models can indeed be horizontally vented and terminated. For more information, please see our Gas Fireplace and Stove Buying Guide. To see our full selection of zero-clearance direct vent fireplaces, please see below:

    By Michael from Marshall, MI on November 5, 2012
    Are there any efficiency measures that we can look at to compare models? Should I look at unvented units?
    By Tyler M. - Fireplace Specialist on November 6, 2012

    Yes, efficiency information is usually documented on each insert's item page, under the "Item Description." Vent-free inserts always provide 99.9% efficiency, as the heat generated by the fuel is not lost through a chimney.

    For more information on our gas inserts, please read our Fireplace Insert Buying Guide.

    I'm confused as to the different types of vents. I would be installing this into an existing fireplace. Which vent type is best?
    By Tyler M. - Fireplace Specialist on January 3, 2013

    If you are looking at installing a full-bodied direct vent insert, you will need an appropriate, compatible vent kit. In most cases, this would be two co-linear (side-by-side) aluminum liners.

    By Kathy from Madison, WI on May 16, 2013
    Can I change the front of my insert without buying a whole new insert?
    By Collin C. - NFI Master Hearth Professional on May 16, 2013

    This will depend on the manufacturer and model number of the insert. Some manufacturers offer decorative fronts and surrounds, while others do not.

    By Craig from Southern CA on January 21, 2013
    What measurements do I need from my existing fireplace to choose a gas insert? Will it vent through the existing chimney? Will I need to modify the chimney? Anything else you can think of?
    By Tyler M. - Fireplace Specialist on January 21, 2013

    If you reply with your fireplace's front (opening) width, the rear width, the depth (front to back) and the the opening height, we can advised on properly-sized inserts. In some cases, you will be able to vent through an existing chimney, depending on its size. Is your existing fireplace a brick/masonry unit or a manufactured (steel) unit? If it is a manufactured fireplace, please reply with the manufacturer and model information.

    By Rachel from Staten Island, NY on November 11, 2012
    We own an old home and are eager to use gas inserts to utilize the old fireplaces. We know the chimneys have blockage with old broken-in bricks etc and that they haven't been used in many a year. What are the benefits and differences in vent-free and vented gas fireplace inserts?
    By Collin C. - NFI Master Hearth Professional on November 12, 2012

    Vented fireplace inserts will have a sealed firebox that will draw combustion air from outdoors, as well as vent its exhaust gases. Most of these units do this by use of a pair of 3-inch flexible aluminum liners and a special termination. The chimney system would need to be cleared and deemed safe to use this type of insert. Vented appliances can be used for an extended period, without affecting the quality of room air. However, these units are not as efficient as a vent free unit.

    Ventless fireplace inserts are completely self-contained and would not require the use of a functioning chimney system. These models use air from within the room for combustion and vent all of their heat directly into the room, making them very efficient. However, because these units use room oxygen, they are limited on run time. They can also have a negative affect on air quality over time and will add moisture to the air while operating. If you have large rooms with high ceilings, this will not be as much of an issue.

    Can a propane insert be placed in a cabinet purchased separately? I'm looking at the Napoleon Princess medium cabinet. Also, do you sell the ProCom fireplace inserts?
    By Collin C. - NFI Master Hearth Professional on June 14, 2013

    Manufactured propane fireplace inserts can indeed be installed into a separately purchased wooden cabinet. The Napoleon Princess mantel is designed to work with certain Napoleon fireplaces, however the cabinet can be modified by a cabinet maker to fit other models.

    Unfortunately, we no longer carry the ProCom fireplace inserts, due to a large number of reliability issues we encountered with them.

    By Will M. on October 31, 2016

    Gas inserts are made to accommodate common fireplace opening dimensions, so most will simply choose an insert based on other factors. All of our inserts will work with your dimensions as they exceed the minimum hearth requirements.

    Hi! I am the manager of a condominium complex with 64 units. We are thinking of converting all of the units to gas fireplace inserts. I have 2 questions for you:

    1. Can these be converted to propane, and is there an additional charge to do this?

    2. Also, if we purchase 64 units, would there be a discount?
    on November 9, 2012

    We sell a variety of gas inserts, and all are available for use with propane. Some units do have an additional charge for a propane conversion kit, while others do not. As for a quantity discount, we may be able to offer some kind of price break for an order of that size. Please reply with a model number and a shipping address and we will let you know what we can do. We look forward to your response.

    Can the blower motors be replaced with DC motors 12Volt or Replaced with AC/DC ? I am thinking of the Innsbrook 25 In.
    By Collin C. - NFI Master Hearth Professional on February 3, 2014

    Because the blower motor is able to be separated from the cage, it is definitely possible to accomplish this type of retrofit. Disassembly and reassembly of the blower housing is a bit of a project, but it can be done. The manufacturer does not offer a DC motor, so you would have to procure a motor of the same rated RPM from a electric motor supplier.

    I want to install a glass pebble fireplace in my existing hearth. I already have the gas connection, but don’t know where to start looking for the actual gas element. I am finding the glass and the inserts online, but this is a brick fireplace with a gas hookup that I want to modify.
    on November 9, 2012

    Are you interested in simply a glass burner assembly? These are very similar to a gas log set but instead of a log assembly and grate, they use glass ember fill. These units simply need a gas line to complete installation. Please follow the below link to check out our collection: Gas Fire Glass Sets If you'd like to reply with your fireplace dimensions and your preference for control option, we'd be happy to match up the proper size set for you. We look forward to your reply.

    By Becky on November 9, 2012
    Just bought a condo which has two wood fireplaces. Haven’t had them checked out yet for chimney safety, but know I would like to have natural gas in at least one. I don’t know what the website means with ‘direct vent’, ‘small vent’, vent free’, etc. I know I want a blower on it to take in cooler air from the room and to blow out warm air into the room. What should I look for?
    on November 9, 2012

    Are the fireplaces in your condo manufactured (metal) or masonry? Depending on what is currently installed, I may be able to suggest a fireplace insert that can be installed into the current unit or you may have to consider other options. Direct vent fireplaces have a sealed glass window across the front and draw all combustion air from outdoors. Likewise, they vent to the outdoors with the same size chimney liner. Vent-free units have no venting system at all. They utilize air from the room for combustion and vent all heat back into the room. They are able to do this by limiting their BTU output and utilizing very sophisticated burner assemblies. Even so, these units are not recommended for smaller spaces, as they can reduce oxygen levels in the room and add unwanted moisture. B-vent (natural vent) units use the same type of piping as a gas furnace or water heater. They vent exhaust to the outdoors through this 3- to 6-inch piping system and draw air from the room for combustion. These units are not as efficient as the other two categories and are largely for aesthetics.

    Can I use an Empire DV35IN33L direct, through the wall, vent kit for my house that has vinyl siding?
    By eFireplaceStore on February 9, 2015

    We are interested in purchasing and installing a 24" bio-ethanol insert, but need to find the appropriate firebox to set it in. What would you suggest?
    By eFireplaceStore on January 12, 2015

    Because most ethanol inserts are vent free, a 36 inch firebox could likely be used for your application. A popular model is the Empire Breckenridge VFD36FB0L Deluxe Vent-Free Louvered Gas Firebox - 36". Another is the Majestic Lo-Rider LCUF Clean Face Ventless Firebox with 36" Opening and Herringbone Refractory Firebrick.

    By Andrea on November 9, 2012
    My 36-inch, vented gas fireplace is over 10 years old and no longer works. My plumber said it is not a gas problem and thought it may be electrical. Do I need a new fireplace or just an insert?
    on November 9, 2012

    If your plumber believes the problem to be electrical, it may be an issue with the gas valve itself. This is often the only component that requires electrical power to operate.

    I have a wooden fireplace cabinet with an electric insert. Can I replace the electric insert with a propane gas insert? The dimensions of the cabinet are:
    W 60//'x H 48" x D 14". The insert opening is W 32" x H 25".
    By eFireplaceStore on October 16, 2014

    This is a common request, however it cannot be done. The cabinets are constructed specifically by the manufacturer for the electric inserts they house. As such, the cabinets do not offer the proper clearances needed for gas fireplaces. I apologize for the inconvenience.

    By Jaret from WA on October 16, 2014

    One of our most popular items in this category is the Empire Loft Direct Vent Gas Fireplace Insert with Intermittent Pilot - 27,000 BTU. This model features a modern linear flame and can be used with fire glass, pebbles, or ceramic stones.

    I have a Jotul natural gas stove for heating, that has a manual push button ignition switch. Do they make fireplace inserts with that type of igniter? We bought that type so we wouldn't have to rely on electricity. If so, can you recommend one to heat about 1500 sq feet?
    By Will M. on December 29, 2016

    For a space of this size, you would need an insert with a BTU output of roughly 52,500. As the inserts we offer have a maximum BTU input of 40,000, we would not be able to offer anything capable of effectively heating the space you describe. Additionally, the inserts that offer a BTI input in this range are non-standing pilot electronic ignition systems. While mostly reliant on 120v, these systems also include a battery backup that will provide ignition and operation for up to 6 months. For a millivolt (standing pilot) system like what you currently have, the Empire Large Innsbrook Direct-Vent Clean Face Fireplace Insert with Blower - Millivolt Controls would be my recommendation. This model offers a max BTU output of 30,000, which would heat a space of roughly 857 square feet with standard 8' ceiling height.

    Also, please note that the front width, rear width, depth and height of your fireplace opening will need to be measured and compared to the minimum hearth requirements for each insert we offer to ensure the insert will fit into your opening.

    Fireplace Insert Buying Guide

    By Bob from NJ on December 19, 2014
    Do I need an insert if I am converting a woodburning fireplace to natural gas with just a gas log fixture and if it has a working chimney and flue?
    By eFireplaceStore on December 19, 2014

    An insert does not necessarily have to be used. If the firebox is in good condition, a gas log set can be installed and used with your existing chimney. However, a fireplace insert would be a good addition for heat. Direct vent and vent free inserts heat much more effectively, but if ambiance is the main goal, a vented log set will work well.

    By Joe from WA on September 7, 2017
    How do I proceed with installation?
    By Tyler M. on September 7, 2017

    For gas inserts and log sets, we typically recommend contacting local plumbing and heating/air conditioning companies, most of which staff gas fitters/technicians that can do the installation work.

    Our house has a gas line piped into the fireplace. We now are in need of a fireplace insert or logs (or both). We have 2 fireplaces (in 2 locations), that both require inserts. I need some help to understand what to buy and how to have it plumbed correctly.
    By Will M. on December 6, 2016

    As an online retailer, we do not provide any in-home consultations and are only able to give technical advice via phone or email. Additionally, any pipe sizing recommendations or installation of gas pipe should only be provided by a locally licensed plumber or gas fitter. Any hearth-specific retailer will only be able to provide technical guidance after properly sized gas pipe has been installed by a locally-licensed gas fitter or plumber. If this has already been done (I apologize as the original question was unclear), I recommend choosing a fireplace insert based on your hearth opening measurements for each fireplace. If you are able to provide the front width, rear width, depth and height for each opening, I will be able to narrow down the selection and locate an inserts that will suit your needs. If you would like to reach me (Will M.) directly, please dial 1-800-203-1642 ext. 404.

    I'm interested in installing the Napoleon LHD50 See Thru Fireplace on the wall between my living room and bedroom. I intend to place a TV over each side of the fireplace. Is that something I'll be able to do with this unit? And does this fireplace come with a light package, blower, trim kit for both sides and twigs that I can use as an inside package?
    By Collin C. - NFI Master Hearth Professional on April 8, 2013

    While a television can be installed above the fireplace, the manufacturer strongly advises that the television be recessed into a wall enclosure. Even with a mantel between the fireplace and the television, high levels of heat can still reach the television and cause damage.

    The unit does indeed come standard with accent lighting that accentuates the glass media in the fireplace. Because of the smooth faced nature of the fireplace, a circulating blower is not an option. The ceramic twig accessory is available as a $45 option for this unit. The unit does not come with trim as standard and will need to be added, should you wish to get the look shown on the website. The available surround colors can be seen under the accessory tab on the unit's item page.

    By Carl from Campton, NH on June 12, 2016

    The sizes indicated in a unit's title generally refer to the size of the opening. All of our inserts will have minimum fireplace opening dimensions listed.

    By Denise from Sunset Beach, NC on November 4, 2013
    Our fireplace keeps going out. The pilot light goes on, but then suddenly flips off. Is this the insert or gas lines?
    By Collin C. - NFI Master Hearth Professional on November 4, 2013

    It is likely that the issue is attributed to a faulty thermocouple, which is the small metal probe that the pilot flame engulfs. When the thermocouple becomes weak, the valve will not receive enough voltage for the gas plunger to remain open. The thermocouple can be cleaned with a small piece of sandpaper, as combustion byproducts can build up on the probe and lower its efficiency.

    My brick fireplace is 45W x 29H x 21D, and is plumbed for natural gas. What type of insert would provide the greatest heating efficiency and not be unattractive?
    By Collin C. - NFI Master Hearth Professional on December 9, 2013

    For a traditional option, the Innsbrook Large Direct Vent Gas Fireplace Insert - Natural Gas - DV-35IN-33LN would be a good choice. The output rating of this unit will be good to heat 800 square feet of area.

    A more modern option with cleaner lines and additional features is the Napoleon Large Deluxe Insert with Night Light and Radiant Ironwood Log Set - 40,000 BTU. The factory log set on this model can also be swapped for ceramic stones and fire glass. Heating capacity for this unit is approximately 1,000 square feet.

    What is the difference between a vented and a non-vented gas insert?

    By Tyler M. on November 17, 2014

    There are several differences between vented and vent-free gas fireplaces, stoves and inserts. Please read our Gas Fireplace and Stove Buying Guide for detailed information.

    What is the difference between vented and vent free propane gas fireplace inserts?
    By eFireplaceStore on January 11, 2016

    Vented fireplace inserts will generally be sealed with a pane of glass and use a pair of 3 or 4 inch liners that are routed up the chimney. One liner will pull combustion air from the outdoors, while the other will vent exhaust gases. The vented systems do not effect air quality. Vent free units are completely sealed from the chimney and vent all heat into the room. The are carefully built to avoid off gassing of dangerous byproducts into the room, but consideration must be made on room size and location.

    We have an existing see-through (living & dining rooms) wood burning fireplace. Can we get a gas insert for it? Will it be visible from both rooms?

    By Tyler M. - NFI Certified Specialist on March 5, 2013

    We do not carry any multi-sided inserts at this time, though we do have some see-thru zero clearance gas models. If you have a brick/masonry fireplace, you can install one of these inside your existing fireplace if there is enough room for the unit itself and the required venting components. Please see our full selection below:

    I do indeed carry an insert that could fit your opening, which can be found by following the link below:

    Empire Loft Direct Vent Gas Fireplace Insert with Intermittent Pilot - 20,000 BTU

    By Joe from Virginia Beach, VA on February 25, 2015
    We have a high efficiency gas hot air furnace. When the electricity goes off during a storm the furnace shuts down so we have no heat in the house. Can a gas fireplace or gas stove insert could be used for backup heat to keep the house warm? The house is on a concrete slab. We have a brick wood-burning fireplace (which we have not used in years) that could accommodate a fireplace insert. Would the gas fireplace insert or a gas stove need electricity to operate and to generate heat into the living space. Does the fireplace need a blower fan to push heat out into the living space? If electricity is needed, is there a backup battery system available that would kick on the igniter and/or operate the blower fan?
    By eFireplaceStore on February 25, 2015

    A gas fireplace insert can indeed be installed to serve as a back up heat source to maintain high enough temperatures in the home to prevent plumbing failure. Most inserts use either a standing pilot or an electronic ignition system with a backup battery, so a power outage would not effect them. They produce good radiant heat on their own, with the fan helping further. However, the fan must have a 120 volt power source to operate.

    Do you have an efficient gas insert(furnace) that is also highly efficient?
    By Collin C. - NFI Master Hearth Professional on April 30, 2013

    Both the direct vent and vent free gas inserts we carry are very efficient. The direct vent range from 75 to 85 percent efficient, while the vent free are 99 percent efficient.

    Is it difficult to insert a gas fireplace into an existing wood insert fireplace? Who runs the gas line?
    By Collin C. - NFI Master Hearth Professional on February 22, 2013

    As long as the gas insert is sized properly to the wood-burning fireplace, installation is fairly straightforward. Gas lines for the unit are generally run by a plumber. In some cases, the same plumber can complete the entire installation, if they have prior experience with this type of appliance. Otherwise, a licensed contractor would need to complete the installation.

    By Phil from Florida on November 20, 2012
    I am renovating a 1910 late-Victorian home that has at least three fireplaces, it may be four. The original cast iron inserts have been removed. I suspect these inserts were originally made to burn coal since bottle gas was not available until the 1930's. The fireboxes appear to have been lined with firebrick.

    These fireboxes are relatively small: only 7.5" deep, 28" high, and 21" wide in the front. They taper inward from the front to a back width of just 18". The dimensions vary among the three, depending on the firebricks. Can I remove the firebricks to provide clearance for a cast iron gas insert? What is the smallest dimension gas stove/insert you sell? The chimneys are open so I would like to use direct vent.
    By Tyler M. - Fireplace Specialist on November 21, 2012

    Unfortunately, you will not be able to install a direct vent insert into these fireboxes. Removing the brick will disallow installation regardless of the increased dimensions, as inserts are designed to be housed within a brick/masonry fireplace.

    The only direct vent option we have for your fireplaces would be a freestanding direct vent stove that can be placed in front of your fireplaces and piped up through your existing chimneys.

    By Marcia from Washington, DC on November 6, 2014
    I currently have a wood-burning stove insert in my fireplace which I often burn 24-7 during the coldest parts of the winter. It has a direct vent flue as well as a blower fan. It works great but I am tired of the mess of dealing with firewood. Would a gas insert be a good substitute?
    By Chris C. on November 7, 2014

    A direct vent gas insert, such as the Empire Innsbrook would be an excellent source of heat rated at 35,000 BTU. This rating does not come close to many wood burning inserts, but the convenience factor can outweigh the loss in heat as compared to a wood burning insert. Being that the unit is direct vent as well as listed as a heater, it can be run for extended periods of time without concern.

    By Megan from Gresham, Oregon on December 11, 2016
    I have a current unit 22 " tall and 26" across. Can you email me a list of inserts that would easily fit (with a price list)?
    By Will M. on December 12, 2016

    If this is a true fireplace insert, meaning that it is installed into an existing wood burning fireplace (prefabricated or masonry), we will need to know the existing hearth dimensions with the insert removed to provide a full list of what will fit inside your opening. Without this, the make and model number of the existing insert may be a starting point to look into models with the same or smaller minimum hearth opening requirements.

    By Trace from Kansas City, KS on June 4, 2014
    We have a basement fireplace that we have been told the flue is no longer useable so we were thinking about putting in a gas insert since it is already piped for gas. The opening measured at the base is 22 1/2 D, 33 1/2 W, & 23 3/4 H. Which insert do you think would work best and does it require the flue to be lined? We have checked into lining the flue and it's rather costly and would prefer not to do so.
    By eFireplaceStore on June 4, 2014

    The gas fireplace inserts that we carry rely on a pair of aluminum flue liners to be installed. Both liners are 3 inches in diameter and can be easily installed in an existing chimney, regardless of the condition. It does not require that you repair the main chimney liner.

    A popular model that will fit your opening is the Empire Innsbrook Medium Direct Vent Gas Fireplace Insert - Natural Gas - DV-33IN-33LN. I will be happy to assist in putting together a quote for the unit and venting, if you would like to proceed.

    By Peter from Long Island, NY on November 2, 2014
    What do I need to take out of the gas fireplace that I have now to put in a pellet stove? Is it a major construction job to do this?
    By eFireplaceStore on November 4, 2014

    This will depend on the size of the opening and the material used in construction. You may be better off to use a pellet stove insert that can be framed into a combustible opening. There can indeed be a decent amount of labor involved with removing the existing fireplace. It primarily depends on how the unit was finished and what facing was used. Ceramic tile can be removed easily, but marble slabs or brick can be more work.

    By Barbara from Woodland, CA on December 17, 2016

    I have an old coal fireplace that I'm looking to covert to gas without dismantling the current set-up and fret. I have a trapezoidal shape with 17.5" W in the front, 13" W in the back, and 8.5" D. I'd like a small gas log insert, but a coal insert would be good too. What are my options for small vent free inserts?
    By Collin C. - NFI Master Hearth Professional on December 16, 2013

    The only vent free burner system that we offer that would fit your application is the Rasmussen Vent-Free Natural Gas Burner with Realistic Coals - 13" - C9A-SE-N. It is made for use with an existing coal basket, so this is the ideal setup to use it in. While I understand you are looking for vent free, we also have a couple of vented setups you may consider as well. They are the Hargrove Faux Coal Vented Burner with Remote Ready Rotary Controls - Natural Gas - FC14-R-NA and the Hargrove Faux Wood Vented Burner with Remote Ready Rotary Controls - Natural Gas - FL14-R-NA. Like the vent free burner, both systems are designed for use with an existing coal basket.

    By Bob from Waco, TX on January 13, 2015
    Can a propane line be run from an open patio through the attic of the house and into the existing chimney to fuel a propane fire place insert. I have an all electric home and wood burning fireplace I would like to convert it to propane. Would this be safe and legal?
    By eFireplaceStore on January 13, 2015

    Because the chimney would be used to house the venting system of the insert, I do not recommend running the propane supply line within the chimney. Heat buildup could eventually cause an issue and potentially damage the line. If the fireplace is on an interior wall, the adjacent wall to the unit would have to be opened up to run the gas line.

    By Fred Schenker from Gettysburg, PA on December 17, 2016

    Are there types of Natural gas burning areas other than log sets, stones, crystals and fireballs for the gas insert into an old wood burning fireplace?
    I thought I have seen some contemporary gas fireplaces that use concrete balls or other types of fixtures for viewing burning flames. I attach stones, balls and straight flame with clever wood charred background.

    By Ryan from China Grove, NC on November 14, 2014
    I am looking to purchase vent free gas logs but I need an insert to fit my fireplace. It is a small tapered fireplace (see the dimensions) and it is difficult to find one that would work. What would you suggest?
    By eFireplaceStore on November 17, 2014

    The depth of your fireplace does limit your selections, but the Empire Small Innsbrook Vent-Free Gas Fireplace Insert with Millivolt Controls would be an excellent choice. The depth is shallow enough and when used with the 6 x 6 surround, the additional width and height of the fireplace opening will be covered. The unit is complete with a set of highly detailed ceramic logs and glowing ember material.

    By Clayton from Florence, AL on February 13, 2017
    I have a WHGC32F-DC mantle and I need a firebox insert that fits this mantle. Which one works? Thank you.
    By Will M. on February 13, 2017

    Please note that your question was submitted in response to our fireplace insert category and fireplace inserts are designed specifically to be installed into an existing prefabricated wood burning or masonry fireplace, however, the mantel you have described was designed for use with the Majestic/Monessen BDV400 product line and, without specifications for the mantel, we would not be able to locate a compatible fireplace or firebox, as the BDV400 has been discontinued.

    By George M from GA on October 25, 2016
    Do you have any gas inserts for arched fireplaces? Our fireplace is a stone arched fireplace (41"X 26").
    By Will M. on October 25, 2016

    We will not offer any inserts specifically made for fireplaces featuring a curved arch design. I recommend simply locating an insert that fits and then fabricating a shroud to cover this arch, should one of the optional surrounds not cover this space.

    By Owen on December 26, 2016

    I would need the dimensions of the opening to help narrow down for you the unit(s) that would best suit your needs.

    As far as local installers in your area, I do not know of any personally. However I could direct you to a list of local Certified installers/techs in your area.

    By Michael from Lakeland, FL on December 15, 2014
    My Empire Innsbrook large direct vent gas fireplace insert (CUI-DV35IN33LP) makes an annoying hum when the fan blows. The noise is present at all times and varies in intensity depending on the fan speed set. It is most quiet at middle fan speeds. The noise in louder and more obnoxious while the blower is operating after the flame goes out and the unit is cooling down. Do you have any suggestions to help quiet the noise?
    By eFireplaceStore on December 16, 2014

    Because of its high resistance to heat, it is best to use small pieces of felt between the blower housing and the chassis of the unit. The hum is most likely being transmitted through the unit by metal on metal contact and the felt can serve as a buffer to quiet the noise.

    Is there a gas fireplace insert for a conventional wood burning fireplace that vents straight into a chimney without separate pipes that go up the chimney?
    By Tyler M. - NFI Certified Specialist on January 13, 2014

    All the gas fireplace inserts we carry either require dedicated venting through an existing noncombustible chimney (direct vent and natural vent inserts), or no venting whatsoever (vent-free inserts). As such, to have no vent kit required, your only option would be to get a vent-free insert for installation inside your woodburning fireplace.

    By ed hunt from Los Angeles on November 24, 2012
    What do you mean by "direct vent" in the context of a small gas fireplace insert? What are the venting requirements? The existing brick chimney is about 8"x 8".
    By Collin C. - NFI Master Hearth Professional on November 26, 2012

    Direct vent fireplace inserts utilize outside air for combustion, as well as venting their exhaust gases to the outdoors. This is accomplished by the use of a pair of 3 or 4 inch diameter aluminum liners. These will be routed up the chimney, side by side, and attach to a termination cap that will cover the top of your masonry chimney.

    Because one liner carries air and the other vents exhaust, the front of the unit is sealed with a solid pane of glass and has no interaction with the air in the room. Because of their efficiency and venting design, these are the most popular style of insert we sell.

    By Dan from Seattle, WA on January 1, 2017
    I want a natural gas-burning insert that would utilize my existing wood fireplace and chimney. I want one with an intake vent for the combustion gases. I don't want one that pulls the combustion gases from the room. What is the standard nomenclature for this type of venting system? Do they require punching a hole through the external wall of my house? (And even the existing firebox?)
    By Will M. on January 2, 2017

    While there is no standard nomenclature for the various brands of flexible venting used with direct vent inserts as this will vary depending on the manufacturer of the insert itself, direct vent fireplace inserts utilize co-linear (side by side, typically 3" in diameter) flexible aluminum chimney liner which is typically sold in kits, including the liner, top plate, cap and any clamps needed. As you have described, one 3" liner is responsible for exhausting flue gases and one liner is responsible for the exhaust. As both liners must exhaust vertically through an existing stainless air-cooled chimney for prefabricated wood burning, or clay lined flue with masonry, you cannot cut a hole through the existing firebox for the exhaust or intake air. Additionally, direct vent insert manufacturers require the existing wood burning system to remain mostly intact and this would render the fireplace and chimney no longer functional for wood burning. To locate models that will work for your installation, please provide the make and model number of your fireplace, in addition to the overall chimney height, measured from the hearth floor inside the fireplace opening.

    By Teri-Lynn from RI on March 20, 2016
    I have an old wood burning stove that is not sealed well and is very inefficient.
    It has a stove pipe that goes outside. Can I put in a propane insert?
    By Will M. on March 21, 2016

    A much better option may be to install a Direct Vent Stove in it's place. Black direct vent pipe may be run to the existing ceiling support box with the remaining chimney relined with flexible aluminum liner.

    By Doug from Chicago, IL on December 13, 2016
    Do they make L shaped inserts for a front and left side opening for a gas vented fireplace?
    By Will M. on December 13, 2016

    Fireplace inserts are only offered for standard, single-sided fireplace openings.

    By Hina from NJ on March 12, 2013
    I want to convert my wood burning fireplace in to gas. What sort of gas insert do I need? Is there anything I need to be aware of when selecting an insert?
    By Tyler M. - NFI Certified Specialist on March 12, 2013

    The biggest consideration you have is the feasibility of fitting a full-bodied insert inside your existing fireplace versus the option of simply installing a gas log set inside (burner and logs). First, please confirm in your manual that the model has been approved for a gas insert to be installed within it. Next, get the full dimensions of your fireplace (opening width, opening height, rear width) as well as the diameter of the flue collar opening and its location relative to the front face of the fireplace. For more information, please see our Fireplace Insert Buying Guide.

    We received a Coleman model 36ECMII as a gift. It has glass bi-fold doors, can you please tell me if this will take fire wood or is it gas only?
    By Collin C. - NFI Master Hearth Professional on January 28, 2013

    The 36ECMII was a long running fireplace model that was designed to be used for wood burning primarily. However, it does have provisions for installation of a gas line. As such, a gas log lighter or set of gas logs can also be used. The unit must be vented using Class A FMI brand pipe. Either the 8DM or 8HT series of piping can be used. I will be happy to assist with any venting needs you may have.

    By Max from Livermore, CO 80536 on January 17, 2013
    I am considering installing a fireplace firebox to use with a propane gas log set and possibly a blower. I understand "ventless" are not legal in our area. Would I need just a vented insert or what. What diameter is the exhaust pipe? I plan to custom build in a framework around the unit.
    By Tyler M. - Fireplace Specialist on January 17, 2013

    As it appears, you do not have an existing fireplace in which to install an insert, so you would have two options. The first would be to purchase a manufactured, zero-clearance woodburning fireplace with the appropriate class A chimney pipe, then install a propane vented gas log set. The other would be to buy a zero-clearance direct vent gas fireplace, which would consist of the firebox, the burner and the gas log set, plus the appropriate vent kit. Some direct vent fireplaces can be vented horizontally straight out from the rear of the fireplaces, while others require a vertical rise but then can be turned horizontally and terminated on an exterior wall. Both of these options would have provisions to add a blower for added heat circulation. If you are looking for a dependable secondary heat sources, we recommend going with a direct vent fireplace. Please see our full selection below:

    Direct Vent Fireplaces

    Please let us know if you have any questions about any of the units, the venting or the blower option(s).

    By Stephnie from Westminster, Maryland on September 24, 2014
    We have a zero clearance fireplace with gas log inserts at the moment. The chimney is a framed (not masonry) chimney. Is it possible to put a direct vent propane gas fireplace insert into this space? I am also wondering if our local building codes allow for a direct vent fireplace.
    By eFireplaceStore on September 24, 2014

    Restrictions against direct vent fireplaces are very few, as these units are quite efficient and have no effect on indoor air quality. However, it is prudent to contact your local code office to verify.

    You can certainly remove the existing wood burning model and install a direct vent unit in its place. Depending on your application, you may be able to route the direct vent pipe through the existing chimney or route it horizontally through the outside wall.

    By Roberts Properties from San Luis Obispo, CA on January 9, 2017
    I am looking for a gas insert for an existing fireplace, to replace the old floor furnace as a heat source for an old Victorian house. It just needs to be basic black design, efficient and thermostat controls, with a blower so that tenants can use it easily.
    By Will M. on January 10, 2017

    For clarity, please confirm you will be removing the floor furnace and just want to add another supplemental heat source in the home. I would assume you will be framing out an opening in a different location to vent whichever fireplace you eventually purchase through the roof or through a wall. If the flame aesthetic and overall appearance is not important when compared to heating efficiency, I would recommend a product like the Empire DV25SG Direct Vent Gas Wall Furnace - Natural Gas - DV-25-SGNAT with the optional blower installed. If you are wanting a fireplace to frame out and finish as you please, please confirm. We will need to know the square footage and ceiling height of the space you would like to heat in order to make recommendations.

    By Nancy from Iowa on January 12, 2014
    I currently have a see-through wood burning fireplace. Can it be replaced with a see-through gas fireplace or a see-through gas insert?
    By Tyler M. - NFI Certified Specialist on January 13, 2014

    If you have a manufactured fireplace, then it can certainly be removed and replaced with a see-through gas model. This would likely necessitate a complete replacement of your existing chimney as well. If you have a brick/masonry unit, we do not carry any full-bodied see-thru inserts, but we do have several gas log set options.

    I have an existing wood fireplace measuring 35" wide, 27" high, and 18 1/2" deep. The back of the firebox measures 26 1/2 inches. I am at, I believe, high altitude: 3600 ft. Which insert should I order?
    By Will M. on October 20, 2016

    This altitude is not high enough to cause any concern, but the Empire Large Innsbrook Direct Vent Gas Fireplace Insert with Intermittent Pilot - DV35IN73LN/P or Empire DXT30IN91N Innsbrook Traditional Medium Luxury Direct Vent Fireplace would be good choices that would work with the dimensions you've provided.

    What is the proper way to measure for a replacement liner? I have a homemade fireplace and the brick liner has cracks in it. I would like to install a new liner but I'm not sure how to properly measure the interior of the fireplace.
    By eFireplaceStore on November 17, 2015

    Because the unit is a non-listed unit, you will indeed have to take detailed measurements. You will need to measure the depth at the top and bottom of each side, as well as the height at the front and back of each side. The back panel will need to be measured for the height and the width at top and bottom.

    By Bill from Boston, ma on November 12, 2013
    How do you determine which fireplace insert (propane) is most appropriate? What are the decision criteria?
    By Collin C. - NFI Master Hearth Professional on November 12, 2013

    You will first need to determine the front width, rear width, depth, and height of the existing fireplace the insert will be installed into. The flue size of the existing fireplace must be measured as well. Next, you will need to determine the amount of square footage that you would like to heat. Once this criteria has been established, we can look for an insert that will meet your needs most closely.

    Which natural gas insert models could continue to operate if the electrical power goes out?

    You would want to go with one of our millivolt units, that has a standing pilot and can operate without electricity.

    How do I size an insert? There is only one dimension that is asked for.
    By Kevin E. - NFI Certified Specialist on September 28, 2013

    Our site organizes our insert options by width measurement. However, to properly fit an insert for you, we would need the front width, rear width, depth and height of your fireplace.

    We have a gas fireplace, but have never installed fake logs or even used it. We would like one with a blower to use for heating our home. Is that possible with a gas line to have an insert? We have a chimney. Size front width across 35-1/2" with 19-3/4" with at back of box, depth is 15-3/4".

    We will be happy to help. If you could, please provide the height of the opening and clarify whether you will be using natural gas or propane.

    I have a wood burning fireplace with a 10" flue. It is also set up to use propane, however I have been burning wood in it. I would like to switch to natural gas (to give myself the ability to turn it on and off when I want to). Can I use the burner and logs from my propane set-up with natural gas or does the burner need to be modified in some way?
    By Brennan W. on December 5, 2016

    You would indeed need to convert the unit over to natural gas using a kit that swaps orifice. If you could, please provide the manufacturer and model number of your set and I will be happy to look into the availability of a conversion kit.

    I have a corner fireplace, 2 sided, front and side view, wood burning, with a natural gas lighter. I would like to change it to a gas fireplace, I need the glass sides and the burners. Do you have any ideas? I currently have the screens, but want the glass.

    I will be happy to look into the availability of glass doors and gas logs for your fireplace. Please provide the manufacturer name and model of the fireplace so I may research this further. There will likely be a build plate on the smoke shelf of the unit or in the void space beneath the fireplace floor that will have this information.

    Modern natural gas or propane fireplace inserts come in two primary forms. Most inserts are "vented" models, which simply means they require access to outside air via a chimney, flue, or dedicated vent in order to carry away the vapors produced in combustion. Among these models are some of's bestsellers, including the Napoleon GI3600 Natural Vent Gas Fireplace Insert. Like most gas fireplace inserts, these models feature clear gas fronts for easy viewing, fans to circulate the heat, and of course vents to carry away the odors and exhaust. When looking for a vented gas fireplace insert, be sure to note how much ventilation the insert will require, and match that to your existing chimney or flue. Otherwise, arrange for a dedicated vent to be built for your new gas fireplace.
