We have a custom fireplace that was created in the 1970's. It has a large, arcing opening that is about 60 inches wide by 12 inches high. Is there a way to find an insert that would cover that type of opening?
By Tyler M. - Fireplace Specialist on November 5, 2012

Unfortunately, none of the inserts we sell are designed to fit in fireplaces that wide or that short. You would likely need to get an insert that will fit in the middle of your fireplace and then have something custom-made to cover the rest of your opening.

By Julie from Millbury, OH on September 21, 2013
We have an almost 3000 sq ft home. It is "L" shaped & has a 2nd floor over the area where the fireplace is. We currently heat with propane, but are looking for a more cost effective way to heat. We have a fireplace & use it on cool evenings. I have read that fireplaces are not efficient & allow a lot of cold air in. Would an insert be cost effective & able to heat our home?
By Collin C. - NFI Master Hearth Professional on September 22, 2013

Realistically, it would be difficult for the insert to heat the entire home, however a larger model would definitely be able to effectively heat nearly all of the square footage. This is especially true if the central air fan is used to circulate heat while the unit is burning.

Open faced fireplaces are indeed inefficient and pull a great deal of dilution air from the room while burning. Some are even negatively efficient. If you would like to provide the front width, back width, height, and depth of your fireplace opening, I will be happy to recommend a few inserts that would work.

We have an older wood-burning fireplace insert, and need a new liner. How do you tell what kind or model it is?

By Tyler M. - Fireplace Specialist on November 26, 2012

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.

Does the Napoleon Deluxe EPA Wood Burning fireplace Insert complete Package Deal feature a fireplace insert very much like or exactly alike the Napoleon Timberwolf EP122 EPA fireplace Insert?
By Tyler M. on October 21, 2014

No, the insert included in the Napoleon Package Deal is the Napoleon EPI-1101P model.

The clay liner in my brick chimney measures 6" by 7" inside dimensions. What liner will fit down this and what inserts will work with that liner?
By Collin C. - NFI Master Hearth Professional on January 23, 2014

The wood burning inserts that we offer require a 6 inch diameter liner for proper operation. Because the I.D. of your chimney flue is already 6 inches, it is possible to vent the insert by running a short section of 6 inch liner from the flue collar of the insert, to the bottom of the first clay flue tile. The liner can be secured at the bottom of the clay flue tile by an anchor plate or other means.

If the clay flue is not in good enough shape to be used on its own, a full liner can be used, but would need to be ovalized slightly to fit properly down the chimney.

By Joann from Tracy, CA on August 9, 2014
I want to replace the front glass screen on my fireplace. Do you know if that can be done?
By eFireplaceStore on August 11, 2014

This will depend on the type of screen that you have. Some screens are integral to the glass frame, while others are removable. Is the fireplace a manufactured (metal) unit or a masonry fireplace with a glass enclosure. If it is manufactured, please provide the manufacturer name and model number of the unit at your convenience.

By Elizabeth from PC Beach, FL on February 18, 2016
We have an insert that we've changed to natural gas logs. Because the doors remain open when the gas fireplace is operating, can we tile over the vents on the top and bottom of the opening?
By Will M. on February 18, 2016

A requirement of installing any vented gas log set will be that the wood fireplace is installed per the manufacturer's requirements as a functional wood burning fireplace. As such, the louvers may not be covered with noncombustible finishing materials.

By Kristin from Oklahoma on December 5, 2013
I have a small corner fireplace that measures about 25 inches wide at the back, and 38 inches wide at the front. It is only about 14 inches deep and has a 21 inch high opening. It currently has a low quality gas log set in it that makes a loud hissing noise when running and produces little or no heat.. We would like to be able to put in a wood-burning insert so that we could produce some heat with this thing. Is this possible? If not, is there a gas insert option that could produce heat?
By Collin C. - NFI Master Hearth Professional on December 6, 2013

Unfortunately, the depth and height of the fireplace will rule out the possibility of a wood burning insert. However, a direct vent gas insert is a possibility. This type of insert would greatly increase the efficiency of the fireplace and could make it a true supplemental heat source. By your dimensions, this seems it might be a prefabricated fireplace. If it is, please advise how far back the center line of the flue is from the face of the fireplace. This is important, as the flexible aluminum liners that attach to the insert must be able to route from the insert to the flue in the few inches of space that is available.

By Kelly from CA on January 30, 2014
I would like to change our wood burning fire place at our home on Catalina Island in California to a fireplace that is gas connected to a light switch to turn on and off. How would I go about doing this?
By Tyler M. - NFI Certified Specialist on January 30, 2014

We offer two means of converting your existing woodburning fireplace into a gas unit. First, we offer a variety of vented gas log sets that can be installed; these feature a burner, log set and a pilot kit tailored to your preference of control. We also carry full-bodied direct vent gas inserts that can slide inside your existing fireplace and utilize your noncombustible chimney to run co-linear (side-by-side) aluminum liners for venting. Please advise as to which category is your preference and also reply with your full fireplace dimensions (front width, rear width, opening height and depth--along with chimney flue size and height). We look forward to your response.

By Mike from Silver City, NM on October 12, 2015
What is required to install a wood burning fireplace insert in a non-masonry fireplace?
By Will M. on October 13, 2015

An approved, fully-functional prefabricated wood burning fireplace with corresponding class A chimney, installed per the manufacturer's instructions and approved by the local authority having jurisdiction.

By John from Bella Vista, AR on October 10, 2014
I have a 1250 square foot house that has a wood burning fireplace that I heat with about 4 months of the year. I would like to change it out to a better model that has doors that seal. The model I have is a Heatilator model HB42A and the fireplace number is AD693290. When I look at your site I have no idea which models would fit in its place without making it difficult on myself. What would you suggest?
By eFireplaceStore on October 10, 2014

An excellent unit for the size of your home is the Superior WCT6820 Signature Series EPA Phase II Circulating Wood-Burning Fireplace. This is a completely sealed, high efficiency EPA model that will heat the area well. The framing height and depth are nearly a perfect match, however the new unit is a bit narrower. We do offer wider models, but the heat output will be much greater than required and will likely cause overheating of the home.

By Stephen from SC on September 21, 2013
I am looking for a catalytic wood burning insert for a firebox that is 39" wide. Can you help me with this?
By Collin C. - NFI Master Hearth Professional on September 23, 2013

All models of wood burning insert that we offer are non-catalytic. While they do not offer the extended burn times of some catalytic stoves, many have the low emission levels achieved by catalytic inserts. If you are interested in non-catalytic model, I will be happy to suggest a few models for your application.

By Martin from Hicksville, NY on February 6, 2015
How do I measure the size of an insert that I need? I have one but I have no clue on what size it is.
By eFireplaceStore on February 9, 2015

The size is based on the front width, rear width, height, and depth of your fireplace opening. Generally, as long as the insert is smaller in all dimensions, it can be used. The only exception is the height. There should be at least 4 inches of height between the top of the insert and the underside of the fireplace opening, in order to allow access for connection of the liner to the unit.

By Robyn from Lima, NY on September 10, 2015
What is the difference between the Napoleon EPI-1101P and the EPI-1402 fireplaces?
By Chris C. on September 10, 2015

There are several main differences between the EPI-1402 and the EPI-1101P. The 1402 features a larger firebox allowing it to achieve longer burn times, higher BTU output, which leads to a greater square footage it is capable to heat. The 1402 can also accommodate a more standard 16" log, whereas the 1101P, having a smaller firebox, can only accommodate a smaller 12" log. While both models are roughly the same depth, the 1402 places more of the insert on the fireplace hearth, which may not be suitable for all installations as this will require a greater distance from the face of the fireplace to any combustible material.

By John from Gaithersburg, MD on February 18, 2016
My insert has both a full front screen and glass doors. Which should I use for night burning? Which will allow the blower to move hot air longer ?
By Will M. on February 19, 2016

For a wood insert, you should keep the doors closed and move the air controls to a lower setting once the fire is established to achieve an extended burn and optimal efficiency. Burning the insert with the screen in place will render the insert inefficient due to the amount of air being drawn into the combustion chamber and the subsequent heat loss up the chimney. Operating a wood insert with an optional screen in place will require fuel to be loaded more frequently to account for the increased air flow, which will also have somewhat of a cooling effect on the firebox. Using the air controls will allow greater efficiency and an extended burn, creating a hotter combustion chamber and a hotter stove will allow the blower to produce heated air for an extended amount of time.

By Paul from Denver, CO on September 26, 2015
I have an arch front fireplace without glass doors. Will that make it difficult to install a wood burning fireplace insert?
By eFireplaceStore on September 28, 2015

Potentially. If the arch is fairly shallow, you may be able to cover it completely with one of the standard shrouds offered with one of our various fireplace inserts. However, it is not uncommon for steeper arches to be more difficult to cover, necessitating the fabrication of a custom backer plate to conceal the entire arch. The backer plate would lay behind the standard shroud and expand the area it covers.

By Nathan from CA on January 29, 2013
I have a fairly tight place to install a wood burning stove. I'd like to install a stove inside my current old pre-fabricated metal insert if possible. Can you help me determine if you sell a stove that would work for me? The height seems to be a problem. I only have about 19.5 inches to fit something in there. Maybe I can have the top section of the metal insert removed or cut to fit an insert inside? Any help or advice you can provide me would be much appreciated.
By Chris on January 29, 2013

Due to the extra heat and weight of a wood burning stove or insert, most prefabricated fireplaces do not support the use of a stove or insert. With a height of only 19.5", we do not have a wood stove or insert that would fit in your existing fireplace

By Alvin from Harrisonburg, VA on December 31, 2013
Do any of your woodburning fireplace inserts come with an ash pan &/or a Heatilator? We would also be interested in one that would have a blower blowing fresh air on the fire as well as having the standard blower blowing the warm air into the room.
By Collin C. - NFI Master Hearth Professional on December 31, 2013

The high efficiency units that we offer come with both a circulating fan that helps with air convection to the room and a secondary air system that uses combustion air to circulate the flame within the fireplace, creating an intense, clean burning fire. However, the inserts are low enough that an ash pan is not a possibility. The inserts will have a cast iron ash lip to help catch ashes that are cleaned from the unit, but all cleaning must be done through the door.

By Glyn from Jacksonville, FL on December 7, 2014
We currently have a propane fireplace. Would it be easy to convert it to a wood burning fireplace?
By eFireplaceStore on December 8, 2014

Conversion to a wood burning unit can be relatively straightforward, but the primary concern is available space for the chimney system. Most prefabricated wood burning models will require a clear space measuring 15 inches by 15 inches in order for the Class A chimney pipe to vent through the roof. I would start by checking to see if that area is available to you.

By Scott from Mooresville, NC on October 4, 2014
I'm looking to put an insert into my fireplace. I have 2600 square feet in the house.

My fireplace measures as such.

Front of the fireplace is 39 inches wide.
The taper in the back is 31 inches wide and 27.5 inches high.
The depth at the bottom is 21 inches and the taper to the top is 19 near the flue.

What would you suggest?
By eFireplaceStore on October 6, 2014

Based on your square footage, I recommend the Osburn 2400 High Efficiency EPA Woodburning Insert with Blower. This large wood burning insert should be able to heat your home at a high burn setting, as long as the fireplace is somewhat central in location. The fireplace opening is large enough to accommodate the unit and as long as you have a 7 inch deep or greater hearth, the front of the unit will fit.

By Daphne from Paso Robles, CA on January 29, 2013
Which models are approved for mobile or manufactured homes? (Inserts only)

By Douglas from Robertsville, Missouri on July 28, 2014
My fireplace insert on first floor appears to vent into a chimney. I do not believe it uses any kind of liner. On the roof, the chimney has what appears to be three separate columns. I use heat exclusively with the fireplace on the first floor. A propane furnace in the basement vents out the side of the house which is not used hardly at all. This new basement fireplace insert won't be used constantly like the first floor but will be used a few days a week. So, what do I need in addition to the fireplace insert?
By Chris C. on July 28, 2014

It is ideal to utilize a flexible stainless steel chimney liner with a wood burning fireplace insert to ensure that the insert is always drawing appropriately. If the insert flue gases are just dumped into an over sized chimney, you could run in to draw problems.

By Gerry from Pineville, lD on February 23, 2015
I have a Martin BE42 firebox but the company is no longer in business. Can this accept a new insert? The owner's manual says not to use an insert without the written authorization from the company. It also says that no insert or other product not specified for use with this fireplace can be used. Can I use an insert?
By eFireplaceStore on February 24, 2015

The statement in the Martin owner's manual is typical of most manufacturers and is ambiguous at best. No fireplace manufacturer that I know of tests specific brands of inserts with their units and as such, there is no list of compatible inserts to fireplaces. However, most manufacturers advise that as long as the insert can be installed into the fireplace with the refractory liners in place and with a flexible flue liner, the installation can proceed.

By Patricia from VA on February 24, 2015
We are looking for a fireplace insert that can go into an existing masonry fireplace with an exterior wall chimney. Our home is 1450 square feet but it's old and poorly built. The fireplace front opening is 36" W x 28 1/2" H x 22" D. The inside back wall dimensions are 28" W x 28" H. I would like an insert with as big of a viewing area as possible that has a quiet double blower. What fireplaces inserts would you recommend?

By eFireplaceStore on February 24, 2015

My first recommendation will be the Osburn 2200 High Efficiency EPA Bay Window Woodburning Insert with Blower. The unit does feature a high output dual cage fan, with the bay front offering a panoramic view of the flames. Another unit with a wide viewing area and the same fan is the Napoleon EPI3T Wood Burning Traditional Front Insert in Black. This model also features and excellent lifetime warranty.

By Sean McGee from New Iberia, LA on February 20, 2013
Can I buy a FMI TUSCAN S42 42" with natural white stacked refractory brick liner directly from you guys and shipped to my house? If so, how much for box and shipping?
By Collin C. - NFI Master Hearth Professional on February 20, 2013

We do indeed have this unit available and it can be seen on its item page. Shipping to your location would be free of charge. You would only pay the advertised sale price listed on the item page.

By Pat from New Jersey on November 3, 2013
Do any wood burning fireplace inserts have both glass and screens? It seems like they usually just have a glass door only.
By Collin C. - NFI Master Hearth Professional on November 4, 2013

The wood burning fireplaces do indeed use just a sealed ceramic glass door. This is because the inserts are only designed to operate with the door closed. As such, a screen is not necessary for operation.

By Larry from Sterling, VA on July 29, 2014
I am looking to replace a 25 year old insert. When I look at your inserts listings I see inserts listed in a variety of prices. So what is the difference in efficiency, quality, durability, etc?
By Chris C. on July 29, 2014

The primary difference between the pricing is going to be the sizing of the units themselves. There are a few models by Timberwolf and USS that the materials used themselves cause the price to drop to be less as well.

By Brian from Summerville, SC on August 25, 2014
What options are available to replace a prefab fireplace with a wood burning insert? Ours measures 36" with a stone hearth and surround. I would like one that can operate even when the power is out. Would the current 6" double wall pipe be able to be reused as it is in good condition?
By eFireplaceStore on August 26, 2014

Wood burning fireplace inserts require an acceptable prefab or masonry fireplace to be installed into. Depending on the model of prefab you have now, an insert could potentially be installed. However, if the prefab is not rated to use an insert or if it is not large enough to house one, the prefab would need to be removed and a high efficiency fireplace used. High efficiency fireplaces function much like a fireplace insert, but have a metal chassis that surrounds the body of the stove, allowing you to install the unit into a combustible wall. A very popular model that can use 6 inch Class A pipe is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace.

By Carl from NJ on February 13, 2016
How do we measure the old firebox insert to order a new one?
By eFireplaceStore on February 15, 2016

The four primary dimensions we would need to know are the front width, rear width, height, and depth of the opening. Please keep in mind that the overall dimensions of the fireplace itself will be larger. Overall dimensions are often called "framing dimensions". These overall dimensions would also need to be known if you wish to minimize the amount of reframing you may have to do.

By Rena from Frisco, TX on September 13, 2014
I have a small wood fireplace and I am looking for an insert that comes in colors other than black. What would you suggest?
By eFireplaceStore on September 15, 2014

In general, most fireplace inserts are only available in a flat black finish and a few porcelain finishes, but these are usually limited to brown or dark green. A black insert can be coated in a high temperature paint prior to installation, but this would have to be done by the end user.

By John from Augusta on August 13, 2014
I'm remodeling a home and would like to add a wood burning fire source but not sure what would be best for efficiency and cost. I'm open to a wood stove unit, but I'm also curious about these "zero clearance" fireplaces. Can you tell me about them? I have no existing chimney or fireplace, but have an interior wall with space behind to build into if needed and with direct roof access for a vent as needed as well. I'm just not sure about the efficiency of fireplaces, as I've heard that vented fireplaces are not good and wonder how/if the zero clearance fireplaces are better or different. Can you tell me what a zero clearance fireplace is exactly?
By eFireplaceStore on August 13, 2014

Zero clearance fireplace is actually a fairly broad term that refers to a prefabricated fireplace that requires little or no clearance to a combustible wall enclosure. Many of these are open face vented models and as you mention, they are not a great source of heat and are largely for looks. High efficiency fireplaces function much like a sealed combustion stove. They use gasketed doors, an air control lever, insulated firebox, and secondary air technology. All of this combines for a small, but intense fire, creating a real source of heat. Modern free standing stoves work the same way.

By Pamela from Front Royal, VA on January 2, 2014
How do I know if my fireplace can support the weight of a wood insert?
By Collin C. - NFI Master Hearth Professional on January 3, 2014

Each prefab fireplace manufacturer will specifically test and list their units for use with a fireplace insert. If this information is not referenced in the owner's manual, the unit was not tested. Please provide the manufacturer name and model number of your fireplace. I can then check compatibility with a wood burning fireplace insert.

By Eric from Passaic, NJ on August 2, 2015
My fire box(fireplace) is 29 wide x 25 1/2 high x 20 deep and the back is 29 inches wide. It doesn't taper. I want a wood burning insert with a large viewing area. What do you suggest?
By eFireplaceStore on August 3, 2015

When it comes to viewing area, one of our most popular wood burning inserts is the Osburn 2200 High Efficiency EPA Bay Window Woodburning Insert with Blower. The large viewing area that the bay front provides is unmatched by the single pane models. The unit can be vented with any of our 304 stainless steel flex kits, such as the DuraFlex 6 Inch Diameter x 35 Foot Long Kit of 304-Alloy Light Chimney Liner.

By sheila from Pennsylvania on December 16, 2012
What is a fireplace insert liner? We have a wood-burning older insert and saw the question. How do you know if something is wearing out on the insert, other than a blower not running? We also have a triple wall pipe from the insert all the way up our chimney. What is the best way to clean this pipe at the end of the season?
By Collin C. - NFI Master Hearth Professional on December 17, 2012

A fireplace liner can refer to either the concrete panels inside the firebox or a stainless steel liner pipe that is installed into a masonry chimney. Generally, the concrete panels can start to crack and deteriorate over years of use.

It is good to check the panels for any signs of cracking, crumbling, or other deterioration. The chimney should be cleaned with a polyethylene brush, as metal can damage a manufactured chimney. Fiberglass rods with a 3/8-inch thread are fairly standard for this type of requirement.

By Jen from NJ on April 29, 2013
How do I measure my current woodburning fireplace so I can find an insert to update it?
By Tyler M. - NFI Certified Specialist on April 30, 2013

In order to provide recommendations for a woodburning insert, please reply with the following information:

Is the existing fireplace a brick/masonry unit?
What is the front width (left to right), rear width, depth (front to back) and opening height of the fireplace?
What is the size of the existing chimney, both in area inside the flue tile and height from the fireplace floor to the cap?

With this information, we would be happy to offer suggestions for your application.

By James from Dublin, GA on January 9, 2014
I have a metal insert wood burning DESA B36 fireplace with no blower system. What model and size wood burning insert do you have that would work in my space?
By Collin C. - NFI Master Hearth Professional on January 9, 2014

I am assuming your B36 is the "smooth face" model without louvers. It would be possible to replace the current system with the FMI Bungalow - Builder 36 Inch Circulating Wood Burning Fireplace, which is the exact same system, but with a louvered face that would allow you to use a rotary fan for air circulation. This would also allow you to use the same chimney system, cutting down on costs.

By Chris Twigg from Woodland Park, CO on September 5, 2014
I'm looking for a wood burning fireplace insert that is made to fit my pre-fabricated Heatilator EL36 fireplace. Do you have any suggestions?
By eFireplaceStore on September 8, 2014

Unfortunately, the information I was able to find on this model indicates that it is not rated for use with a wood burning fireplace insert or unvented gas logs. The unit is rated for use as an open faced wood burning model or for use with vented gas logs only. The fireplace is likely not robust enough to handle the weight of an insert and the additional heat this is generated.

By John from Connecticut on February 12, 2014
Where can I get help with installation?
By Collin C. - NFI Master Hearth Professional on February 12, 2014

Installation of wood burning inserts falls into a specialized field. The first resource to check is the NFI database, which has a list of specialists that are certified to safely install appliances. The database can be searched by ZIP code here. If there is not a wood burning specialist local, a reputable contractor should be the next step. There are many licensed small job contractors and handymen that would be able to complete this type of job as well.

By Kathy from OR on August 21, 2013
Can I burn just paper in my wood burning fireplace insert?
By Tyler M. - NFI Certified Specialist on August 22, 2013

While newspaper can make for good kindling, we do not recommend only burning paper in a woodburning insert. These are designed to burn only real wood.

By Don from Manchester, VT on September 22, 2014
How heavy is this US Stove unit, and is it shipped in multiple cartons because of the surround and the firebricks?
By eFireplaceStore on September 23, 2014

The U.S. Stove 2200 insert has a total weight of 296 pounds. The unit will come shipped on a single pallet, with the bricks already within the unit, however they require final arrangement. The flashing will be boxed and shipped on the same pallet as the unit.

By Ralph from Avon, CT on July 17, 2013
Do wood burning fireplace inserts come for see thru fireplaces ?
By Tyler M. - NFI Certified Specialist on July 17, 2013

Unfortunately, no, we do not offer any see-through (two-sided) fireplace inserts at this time. We only have these models available in a zero-clearance fireplace.

By B J from Fort Smith, AR on December 8, 2013
When I bought my house there was an insert in the fireplace. It was very ugly so I removed it with the intention of just using the fireplace alone. After having it cleaned I was informed that the back wall of the firebox was not stable and that I would always have to use an insert in order to use the fireplace. The rest checked out just fine. Is this safe and is there any type of insert that would be better suited for this situation?
By Collin C. - NFI Master Hearth Professional on December 9, 2013

Using an insert would definitely be the way to proceed, as using wood logs in a fireplace with an unstable firebrick lining could result to crumbling and damage to the surrounding structure. If you would like to provide the dimensions of your fireplace, I will be happy to make a recommendation.

By Julie from TX on November 2, 2015
We are looking for an insert for our fireplace. The opening dimensions are 29" H X 32" W. Can you help us find a stove that would fit?
By Will M. on November 3, 2015

You will need to compare your hearth dimensions to the minimum opening requirements provided on pages 7-8 of this installation manual, but the dimensions you did provide would meet the height and width requirements for the Drolet Escape 1400 Wood Burning Fireplace Insert W Blower Included - DB03120.

By Ron from MO on August 6, 2013
I have a Heatilator SC60 wood burning fireplace. What wood burning insert can I install?
By Tyler M. - NFI Certified Specialist on August 7, 2013

Most of our woodburning inserts are meant for installation inside a masonry/brick fireplace, though some are listed for use within manufactured units. However, you will need to check with Heatilator to see if your particular model is approved to house a woodburning insert. As we are not a Heatilator dealer, you will need to contact one to get this information.

By David Gruber from Blairsville, GA on October 24, 2012
We have a very large fireplace and are considering putting in a wood-burning insert. What is the largest glass door dimension you have for a wood-burning fireplace insert? We are trying to find the largest out there.
By Collin C. - NFI Master Hearth Professional on October 24, 2012

The largest door opening will be on the Osburn 2400 fireplace insert. This model has an opening size that measures 19 1/2 inches wide by 8 1/4 inches tall.

Fireplace inserts typically have a small door size, to ensure high efficiency and a more complete burn of the fuel supply.

By Lynn from New Jersey on October 30, 2013
I have a Marco Model 792776D fireplace. These are not manufactured anymore as far as I can tell. There is a crack in the back panel of the liner. How can I find a suitable replacement liner? Are they fairly easy to replace or do I need to find a service professional to remove the old one and put in the new one? I can buy high-heat mortar to attempt a repair, but are there any guidelines on sizes of cracks that are (or are not) suitable for this approach?
By Collin C. - NFI Master Hearth Professional on October 30, 2013

When cracks develop within the concrete refractory liners, a repair of the liner itself is not feasible. Any repair mortar has a tendency to separate from these panels.

A universal panel such as the Hargrove Replacement Fireplace Refractory Panel - 24 inch X 28 inch can be purchased and cut to fit. A standard tile saw or circular saw with a masonry blade can be used to cut the panel. Replacement of the panel is fairly easy. Usually the side panels are held upright with metal retaining brackets at the top of the panel. The brackets must be removed, allowing the side panels to be pulled from the unit. This in turn will allow the back panel to lean forward and be removed.

I have a 20-yr old insert that is open to the front. I'd like to remodel so that the flames can be seen from two sides. The side that would be open is 16" deep. How shall I go about this?
By eFireplaceStore on June 30, 2014

The existing unit would need to be replaced with a model that allows flame viewing from each side. The type of fireplace that has one long side open and two short sides open for fire viewing is known as a bay style. These bay style units are a bit difficult to find and we no longer offer this configuration.

The peninsula style is still popular, but these models have two long sides open and only one short side. An example is the Empire Tahoe Premium Direct Vent Natural Gas Peninsula Fireplace - 36". I apologize that we do not offer a bay front style any longer.

Which insert would I need to replace the pre-fabricated tile in the refractory? I have a minor crack on the back panel of my Marco Fireplace.
It is a zero clearance built in fireplace fire chamber intended for use with
Marco listed fireplace parts minimum clearance to combustible services
top zero sides 0 floor 0 back 0 chimney one use Marco listed model
number BKR 36.

By eFireplaceStore on October 1, 2014

A fireplace insert is actually a wood burning appliance that is designed to be installed into an existing fireplace to boost efficiency. It sounds like you are describing a refractory panel. Marco is no longer in business, be we do carry universal panels that can be cut to fit and used as a replacement. One such product is the Hargrove Replacement Fireplace Refractory Panel - 24 inch X 28 inch. A tile saw or a circular saw equipped with a masonry blade can be used to cut the panel to size.

I have a wood burning fireplace and I want to put a pellet burning insert in this fireplace. Do you carry pellet burning fireplaces?
By Tyler M. - NFI Certified Specialist on November 4, 2013

Yes, you can see our pellet fireplace inserts here:

Pellet-Burning Fireplace Inserts

By Dave from Huntingdon Valley, PA on November 21, 2014
How do the Napoleon EPA inserts differ? The one that is rated at 70,000 BTUs seems to extend outward whereas the 55,000 BTU model looks flush with the fireplace.
By Chris C. on November 21, 2014

The EPI-1402 is a better unit when compared to the smaller EPI-1101P. The 1402 features a larger 2.25 cubic foot firebox measuring 18" x 18" x 12", compared to the 1101's 1.7 cubic foot firebox measuring only 13.5" x 18" x 12". With the greater sized firebox comes a longer burn time, greater BTU output, as well as a greater space in which the 1402 can heat. The 1402 comes equipped with two blowers, while the 1101 has one blower resulting in a lower CFM rating. The downside to the 1402 is that with it extending so far from the fireplace opening, it requires a greater distance to combustibles from the fireplace opening than the smaller 1101 as it sets flush with the fireplace opening. Lastly, being that the 1402 sets out further from the fireplace opening, you will have an 8" step in which steamers or other stove top accessories can be used.

By Tom from Eugene, OR on July 4, 2015
My home is about 1400 square feet and I currently have a brick fireplace with a line chimney and an older "Country insert". My fireplace size is 23" H x 20" D x 40" W with a front hearth that is 72" W x 24" D. Would the Napoleon Timberwolf fireplace insert be a good match for this size of house? Also, would it fit into these fireplace dimensions?
By Will M. on July 6, 2015

For a masonry fireplace and corresponding terracotta lined masonry chimney with the provided dimensions, the Timberwolf EPI22 would be an excellent choice. We will always recommend verifying the additional clearance information for any masonry insert and Napoleon provides this information on page 9 of the installation manual.

By Bryan from Columbus, OH on September 30, 2014
I have a masonry firebox that I would like to keep and install an insert into. I had to remove the chimney down to the damper due to structural issues. I do not want to tear out the brick fascia, mantle, or firebox. My mason recommended that I buy an insert and replace the chimney with a triple wall pipe and a wood chase. Do you offer an insert that will slide into a traditional brick firebox and utilize a triple wall flue in a wood framed chase?
By eFireplaceStore on October 1, 2014

This type of scenario is actually relatively common and the wood burning inserts we carry can be adapted without an issue. A short length of flex liner would need to be routed up through the damper and into an anchor plate atop the brick firebox. Double or triple walled chimney can then be attached to the anchor plate and supported within a wooden chase.

By Gilda from NY on October 9, 2015
In the event of an electric outage, could a wood fireplace insert work without a blower? If so, what should I expect from the performance of the unit without a functioning blower?
By Brennan W. on October 9, 2015

The blower is simply meant to help push the heat around the room. Your insert would still operate well in the event of a power outage. The only difference would be that it may radiate more slowly then it would with the blower operational.

By Marte from Justin,TX on November 21, 2014
We have a 9 year old wood burning fireplace that is beginning to wear out. Do you sell the replacement panels for my insert?
By Chris C. on November 21, 2014

We do indeed carry the Hargrove Universal Refractory panels as a set of 2 panels that can be cut to size. We also offer a smaller single Hargrove panel as seen here.

By Faye from GA on February 14, 2014
We have gas logs in a manufactured home, with a damper which is closed when not using gas. Propane is costly, so I want to install a wood burning insert. What do I need to convert, to insure safety and not catch my home on fire? It has a cap on the outside above the roof.
By Collin C. - NFI Master Hearth Professional on February 14, 2014

To begin this potential conversion, you will need to know if your current fireplace is a manufactured model or a masonry structure. If it is a manufactured version, the brand name and model number of the unit will allow us to check for insert compatibility and sizing. If it is a masonry version, you will need to know the front width, rear width, depth, and height of the opening. The dimensions of the chimney flue will also be needed.

By Bob from Kansas City, MO on November 21, 2014
I have an insert that was installed by the previous owner about 11 years ago. The fan is working but it moves little air. What can I do to make it work better? Also, how do I determine what make and model my insert is?
By Chris C. on November 21, 2014

The blower assembly looks to be directly below the door on the insert. Over time, ash, dust, hair, as well as other items may have been pulled into the blower assembly restricting air flow, and possibly clogging the fins on the rotary blowers reducing the amount of air flow. Cleaning out these contaminants may help to increase the air circulation. To determine the model of the unit installed, you may have to pull the insert from the fireplace, or at a minimum remove the surround flashing as there may be a data plate attached directly to the body of the insert, or secured by a short length of cable to the insert as well.

By Linda from Charleston, SC on November 3, 2014
I want to install a wood burning fireplace in a 1940's house on a wall where none exist. Do you have an insert that will work with basically new construction?

By eFireplaceStore on November 4, 2014

Wood inserts will require some sort of masonry enclosure or prefabricated fireplace to be in place before installation can take place, as they are not insulated for use in a wooden enclosure. However, we do offer several high efficiency closed combustion fireplaces that work like an insert and can be built into a framed opening. One such product that is a popular seller is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace.

By Wayne from Bandon, OR on May 4, 2013
Are there any pellet fireplace inserts that will also burn natural wood??
By Tyler M. - NFI Certified Specialist on May 6, 2013

No, all pellet inserts are only suitable with wood pellets, not wood logs, and all woodburning inserts are only suitable for logs, not wood pellets.

By Dan from Sheridan, IL on January 25, 2013
I have a Heatillator a42c. What insert can I use?
By Collin C. - NFI Master Hearth Professional on January 25, 2013

This unit is able to use any listed wood burning fireplace insert, with the addition of a chimney liner. I was unable to provide the actual firebox dimensions for this unit. If you will provide the front width, rear width, depth, and height of the firebox opening, I will be happy to suggest the appropriate insert(s) for your needs.

By jeff from St. Louis, MO on February 25, 2013
I am looking to have a wood or gas insert installed. I would also like to redo the brick and replace the mantel. I am thinking of covering the brick with some sort of stone veneer.

My question is this: we are remodeling our kitchen and first floor so we are looking for ways to keep our budget under control. Would it be possible to do this in stages, like install the insert first and stone veneer next year or visa versa?
By Collin C. - NFI Master Hearth Professional on February 26, 2013

It would certainly be possible to install the insert first, then finish the surround at a later time. Depending on how large of a unit you are planning on installing, you may be able to remove the current fireplace and replace it with a similar sided model, which could be temporarily trimmed out.

You could then remove or cover the brick veneer at a later time. I do not recommend trying to do the stone veneer first, as it will make the installation of the new unit very difficult.

By Cold from Eastern PA on June 10, 2014
We currently live in a condo that has a Martin SA36 fireplace hosting an old propane gas-log set. What, if any, options do we have for converting to a wood or wood pellet insert or fireplace that would produce meaningful heat in a 1700 sq. ft living area?
By eFireplaceStore on June 11, 2014

Per the tech I regularly work with at Vermont Castings Group, which absorbed the remainder of Martin after bankruptcy, the Martin SA36 was never tested or listed for use with a solid fuel insert of any kind. The unit was only tested and listed in an open faced guise with solid wood logs and decorative gas log sets. It is possible that installation of either a wood or pellet insert would not cause a problem, but because I have no way of knowing whether or not the fireplace would insulate properly, I cannot recommend it. Your best option is likely to remove the current unit and install a high efficiency wood fireplace. Another possibility is to discontinue use of the fireplace and install a free standing wood stove or pellet stove elsewhere in the home.

By George Meyer from New York on November 23, 2012
We have a "metal box" fireplace in our 10-year old house. Is there a wood burning insert you could recommend? I was told two different things by two retailers.
By Collin C. - NFI Master Hearth Professional on November 26, 2012

The use of a wood burning insert within a manufactured fireplace can indeed be a fuzzy subject. In order to be able to use the insert, both the manufacturer of the insert and the manufactured fireplace must specifically state that they can be used in the corresponding type of unit.

Do you know the manufacturer name and model number of your existing fireplace? There is usually a build plate that is affixed to the unit, either in the bottom compartment beneath the floor or on either wall, just inside the opening near the top.

By Leo from Medford, OR on January 20, 2015
I am looking at installing a 2200I wood insert where I currently have a Warnock Hersey Superior Model BC-36-2 solid wood burning fireplace. After removing the Superior fireplace I am left with an opening large enough to install the 2200I insert but the opening has combustible walls. What are the clearances required for behind and to the sides of the insert to a combustible wall?
By eFireplaceStore on January 20, 2015

Unfortunately, a wood burning insert is unable to be installed into any opening with combustible walls, even if the combustibles are shielded. The manufacturer will only allow installation into an existing masonry chimney or a listed prefabricated box. Your best option will be to install an unit such as the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace. This unit functions much like a wood stove, but can be built into a wood framed opening.

By Chris from Maysville, Kentucky on February 27, 2014
Im looking for a zero clearance insert with very high efficiency. This will be all new construction and will have all combustible products (false stone) butting up to it. We will probably have tile in front of it on the floor. I have looked at the Stratford and the Monaco but was wanting some input.
By Collin C. - NFI Master Hearth Professional on February 27, 2014

The Stratford and Monaco are sister units that both have the same 77% efficiency rating, which meets the EPA Tier II requirements. These models can effectively heat 2,500 square feet and feature a pair of built in 100 CFM circulating fans. These also have the option for installation of a supplemental heat circulation system, which can be tied into the plenum of your forced air furnace.

By Dave from Wake Forest, NC on August 30, 2015
I don't have a chimney, just a vent for a propane burning fireplace. What do I need to replace my propane burning fireplace with a wood burning unit that is good for heating a large room?

By eFireplaceStore on August 31, 2015

In order to utilize a closed combustion (heater rated) wood burning fireplace, you will need to ensure you have the overhead space for a double walled Class A chimney. At their smallest, the chimneys have an 8 inch outer diameter and require a 2 inch clearance to combustibles.

By Debbie from Locust, NC on October 25, 2013
What is the proper way to measure our fireplace (especially depth measurement) to be sure we have all the proper measurements to know if the insert will fit?
By Kevin E. - NFI Certified Specialist on October 27, 2013

Measuring for an insert is rather easy. You'll want to take a front width, rear width, depth and height measurement. For the width measurements, simply measure left to right at the very back of the fireplace and just inside the fireplace opening. For the depth, measure straight back from the fireplace front lip to the rear wall, right in the center of the fireplace opening. The height measurement would also be taken at the center and just inside the fireplace opening.

By Vic from Paris, TX on January 11, 2014
I am researching wood burning fireplace inserts for my Mom and she wants a cooking surface. Most of the inserts I see have little or no cooking surface available. Her idea is that when the power goes out, she wants to be warm and have a place to heat up the soup! She had an old Sweet Home stove in her old house and it had a surface big enough for a large kettle. Are there any stoves with such surfaces available now?
By Collin C. - NFI Master Hearth Professional on January 13, 2014

It is indeed true that most wood burning inserts do not have an area large enough to cook upon. The average depth of the top plate is only 4 inches. However, we do offer the Napoleon EPA Wood Burning Fireplace Insert - EPI-1402. Because this model is designed as more of a hearth stove, it offers an 8 inch surface on which to place a kettle or steamer.

By Nina from Wisconsin Dells, WI on August 6, 2014
I am building a metal arched building. I would like to install a wood burning fireplace in the building. I was wondering if you have ever worked with an arched steel building installation. If not, I am thinking that the best way to install the fireplace is to have the box on the inside of the structure and have the vent outside of the building as much as possible. Can you suggest something that will work?
By Chris C. on August 6, 2014

The installation of a wood burning fireplace within an arched metal building could be fairly simple with the exception of the penetration of the chimney pipe at the roof line. Depending on slope of the roof, a standard metal roof flashing may not accommodate the slope allowing water to seep through. Installing the fireplace on an exterior wall would be the easiest route to take, however the chimney pipe would need to be housed in some sort of an insulated enclosure to ensure that the flue gases remained hot enough to draft properly. If the too great of a length of the chimney is exposed to the elements, you could experience poor draft, and creosote build up.

By Ernest from FL on November 21, 2014
Would my FMI fireplace insert, model 3600, which was manufactured in 1992 be EPA Phase 11 certified?
By eFireplaceStore on November 24, 2014

Unfortunately, no. This model was manufactured before EPA testing on wood burning fireplaces came to prominence. This decorative model of hearth appliance does not offer the efficiency or emissions controls necessary to meet the EPA guidelines.

By tanya from Northern California on November 15, 2012
We have a fireplace insert that is probably really old and has no blower. It sucks at putting out heat, and eats up so much wood to even get kind of warm. We are just renting the place but we don't want to freeze to death this winter.

I want there to be more heat output but not have to go through so much wood. I was wondering if it were possible to put like a glass ceramic door on it to help let some of the heat out? Because the only other thing I can think of to get the heat flowing into the house is to get a screen and just leave the door open - but that is going to burn through wood even faster. Help!
By Collin C. - NFI Master Hearth Professional on November 16, 2012

Older wood burning inserts can be plagued with inefficiency issues, depending on how they have been installed.

Have you removed the metal shroud from the unit to see how it is vented into the chimney? If the unit is installed with the wrong size liner or no liner at all, they can use an exorbitant amount of fuel in a short period of time. I would definitely check the type of connection that is in place, as this may be the problem.

By Paul from Arlington, Texas on December 31, 2012
I have a see-through fireplace and I am considering options for getting better heat output. Is an insert an option? The size of my fireplace is 40" wide, 33" deep, and 27" high. At present, I have accordion glass doors with a screen on each side. Do you recommend wood or gas? What are the trade-offs?
By Tyler M. - Fireplace Specialist on January 2, 2013

We do not carry any multi-sided fireplace inserts. However, you may be interested in a ventless see-thru log set which will provide good supplemental heat. Please reply and let us know what kind of fuel you would use for a gas log set (natural gas or propane), as well has how you want to control the unit (on/off remote, variable flame remote, wall switch or manual.) We will be happy to offer some recommendations.

By Tim from Twining, MI on October 5, 2015
We bought a Napoleon Timberwolf EP 122 insert and just recently used it for the second time. The blower comes on but does not blow out. Do you know what could be causing the problem?
By Will M. on October 6, 2015

The blower simply pulls air around the chassis of the stove and "pushes" this air from the small opening above the top of the door. A common misconception is that the blower will actually "blow" air and this is not correct. Typically, the air is pushed from this small opening at about 1 mph after being pulled into the blower at around 5 mph.

By Anita from USA on November 9, 2012
I have a wood burning fireplace in my house. It is a "kit" unit with ceramic panel inserts. Through years of use the rear panel has started to delaminate and fall apart. I am looking for replacement panels. Do you have any suggestions?
By Staff on November 9, 2012

We have a couple of options for your situation. First, if you have the model and manufacturer of your unit, we can check availability for a replacement panel for your unit. If you cannot get that information, we do have some universal replacement refractory panels for wood-burning fireplaces.

Please see the following links:

(One 24"h x 28"w Panel) Universal Fireplace Refractory Panels 1

(Two 24" h x 40"w Panels)Universal Fireplace Refractory Panels 2

These panels are about 3/4" thick and can be cut down to the size you need with a masonry blade.

Please let us know if you have any additional questions.

By Mike from USA on November 9, 2012
I currently have a 42" SC60 Heatilator Fireplace installed with a specified fireplace frame. Can the Osburn 2400 be inserted in this enclosure (after removing retaliator) or MUST it be inserted into a masonry fireplace? If it can be inserted into the existing framed enclosure, can the 6" flue be adapted to current 8" (10.5" OD) double-walled chimney pipe?
By Staff on November 9, 2012

The Osburn 2400 must be installed into a masonry opening and cannot be used in any other way. Your only other option would be to install a zero-clearance, high efficiency fireplace. These are a double walled type of appliance that function much like a wood stove. One of our most popular sellers can be seen here: Fireplace.

In regards to the second part of your question, this unit uses a 6" chimney system. I cannot recommend converting it to a larger chimney, due to the high efficiency nature of the fireplace. Larger chimneys will often cause these units to perform poorly and create excessive amounts of soot and creosote.

By Brian from hackettstown nj on January 8, 2013
I have a Marco 792776d fireplace. The fireplace really gives off no heat while burning. I was wondering, is there an insert that would work with this fireplace?
By Collin C. - NFI Master Hearth Professional on January 8, 2013

It is certainly possible to install a wood burning insert in some manufactured boxes, but I simply cannot say for sure with your model of Marco. I was unable to find a manual for this unit, so I am unable to verify. I do not recommend it without the manufacturer saying so, as the box can overheat or be damaged otherwise. Do you have any original literature for the box? If so, it should cover the use of inserts.

By Arlander from Plymouth, NC on January 27, 2013
How do I clean the inside of a fireplace insert?
By Collin C. - NFI Master Hearth Professional on January 28, 2013

Because fireplace inserts do not have a conventional ash pan, they must be cleaned by using an ash rake or shovel to pull ashes to the door opening. The ashes can then be scooped into an ash bucket or removed with an approved ash vacuum. The chimney liner should be brushed from the top down and the baffles removed in the insert prior to this process. This will ensure that all material is removed and can be swept from the firebox.

By Keystone Chimney from Levittown, PA on November 26, 2015
Do you sell a zero clearance wood stove insert?
By eFireplaceStore on November 27, 2015

Unfortunately, the wood stove inserts we sell are not zero clearance. These models can only be installed into an existing masonry or prefabricated fireplace that is rated for such an insert. A model of fireplace that we offer that has similarities to a wood burning fireplace insert is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace. This model utilizes a closed combustion high efficiency burn chamber, like the current generation of fireplace inserts. The unit is essentially a stove built into a chassis that allows it to be framed into a combustible wall.

By Sarah from OH on July 25, 2013
Which inserts have ash pans?
By Collin C. - NFI Master Hearth Professional on July 25, 2013

Unfortunately, none of the wood burning inserts we carry have pans. Some models do exist that have pans, but the manufacturers we carry opted to keep the unit as short as possible. This eliminated ash pans from being incorporated into the designs.
