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

Answer:
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.

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

Answer:
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

Answer:
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

Answer:
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

Answer:
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.

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

Answer:
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 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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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 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

Answer:
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

Answer:
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

Answer:
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.

By Katy from Edmonton, Alberta on June 29, 2014
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

Answer:
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.

By PJ from Westchester, NY on September 30, 2014
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

Answer:
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.

Pellet-Burning Fireplace Inserts

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

Answer:
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 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

Answer:
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 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

Answer:
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

Answer:
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

Answer:
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

Answer:
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

Answer:
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.

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

Answer:
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.

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

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

Answer:
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.
