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

How do I measure the fireplace for the correct fit of a wood burning insert?
You will need to measure the front width, rear width, height and depth of your fireplace opening. If you have a masonry fireplace with a taper where it is less deep at the top of the opening than it is at the bottom, you may need to consider the measurements of the insert you are considering. If there is any question about this, please feel free to call me (Will M., NFI Certified Master Hearth Professional) directly at 901-363-8406 or 1-800-203-1642 ext. 404.

I have a mobile home with a fireplace and would like to have a fireplace insert. Can this be done?
You should first contact your local building code officials to see if you can install the unit and ask the requirements they may have on that type of installation and the permit required. After you know, you can install that locally.

I have removed a wood stove from my home, and will be building an area for fireplace in a new part of the house. I am not sure if it makes more sense to buy a fireplace insert, buy a wood insert or go the pellet route. I love the heat from burning wood but also want something that be efficient. The wood stove that we had was an older model that came with the house, and would heat a good portion of the house.
Pellet burning appliances are certain the most efficient type of solid fuel heater on the market, however the do require a good deal of regular maintenance to keep them operating at top efficiency. If weekly cleaning of the appliance is not a realistic match for your application, I recommend looking at a high efficiency wood burning fireplace instead. A popular seller of ours in this category is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace

I have a coal fire place that has not been used before bought my house.How do I convert it to wood burning? I know with electric, I could just put a insert. How much heat does an electric fireplace give off or is mostly for show?
In order to burn wood in this fireplace, it will need to be inspected for safe operation. For this, we recommend using the Chimney Safety Institute's website
to locate a certified chimney sweep in your area.
To answer your question regarding electric hearth systems, they will produce heat but are limited to around 5000 btus. This will heat a space of approximately 143 square feet.

I have an existing double sided fireplace. I would like to get an insert to fit inside, and utilize the chimney for real wood burning, or pellet. Do you have anything that does not require demolishing the hearth to fit in (less than 30" high)?
Unfortunately, we do not offer and are not aware of any inserts that will work with see-through fireplace openings.

from Detroit, MI asked:
November 16, 2016
Is this item gas or electric?
If you are wanting to know whether to choose a gas or electric fireplace insert to install into your masonry or prefabricated wood burning fireplace, there benefits and drawbacks with each option. For electric inserts, the positive aspect will be the low cost of the insert itself and installation. With electric systems, you will not have to pull any permits or hire a licensed or certified, however, the drawback of installing any electric insert is they are limited to around 5,000 Btus which will only heat a space of around 144 square feet. With gas inserts, the heating capacity is much greater. Additionally, the burner, logs and flame will provide a much more realistic appearance. The cost of installation will involve having to pay a licensed plumber to run a gas line to the hearth opening, but this may be roughly the same with the installation of an electric insert if electricity has not been run to the opening and a licensed electrician must be contracted. With gas inserts, the cost of the insert itself may also include additional components that would not be needed with an electric insert. Also, if you are considering a ventless insert, these are not allowed in all jurisdictions.

Do you have inserts for two sided fireplaces?
We will not offer any see-through inserts as products of this type are not currently manufactured. For a see through fireplace, our only recommendation will be to install two ventless inserts, back-to-back.

I have a Majestic Insta Flame natural gas fireplace. Model: DVR36 RP. Serial #: B11B0097092094. BTUH appears to be 18,299. I need a replacement fireplace insert for the upper center panel. Can this be ordered individually or do the inserts come in a set?
Up until a few years ago, we were still able to special order parts for this unit, including the interior panels. However, the manufacturer has now discontinued parts support and I'm afraid that we are no longer able to source a suitable replacement. I am very sorry for the inconvenience.

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

July 1, 2016
What is the difference between vent and ventless insert? Also, which one is better, electric or gas inserts?
There is a wealth of information available here
that should answer any questions regarding vented vs. vent free inserts.
When deciding between electric vs. gas, the primary concern should be heating capacity as electric fireplaces and inserts are limited to 5,000 Btu. Another concern will be the aesthetics of an electric fireplace when compared to gas as only the higher end electric inserts will offer a comparable flame. The advantage of an electric fireplace will be the ease and cost of installation. Aside from potentially having to hire an electrician to provide power if it is not currently located where the fireplace is to be installed, you will not need to hire a licensed plumber or gas fitter to perform the installation.

I'm getting a new house with a ventless fireplace insert. Can we put the fire glass pieces in it without a problem?
Media like fire glass or stones will be listed for use with the vent free appliance of your choosing and you will only be able to use media of this type if the product literature for the vent free system of your choosing has been tested with glass media. Fire glass burners are configured differently to accept fire glass and using this decorative material in a vent free system that cannot use glass media will likely result in unsafe operation.

How do you remove the brick liner and baffle on a Majestic 380IDV fireplace insert so you can take the manifold off?
This will involve removing the glass to remove the bricks via the retainer clips that hold them in place. After this is done, the baffle should easily be removed. Clarity is provided for removal of the manifold on page 14 of the installation manual.

November 23, 2015
Will the Empire Innsbrook Medium Direct Vent Gas Fireplace Insert DV33IN33LN be a good selection for a fireplace located in a 375 to 400 square foot room? To control the room temperature, when you use a FRBTC Remote with Thermostat control, does the fireplace (flame) turn on and off or does the blower just reduce speed?
Please note that the product in question is a fireplace insert, meaning that an existing masonry or prefabricating wood burning fireplace is required to install this appliance. However, this insert has a BTU input of 33,000 with 77% efficiency. To heat the space you have described, you will only need around 14,000 BTUs. Like all millivolt valves, the thermostatic remote would simply turn the burner flame off and on, depending on the temperature and the blower would operate independently.

If you install a wood burning insert, can you safely mount a TV above it or will the heat damage the TV?
So long as the television is installed per the mantel clearances outlined in the installation manual for the insert you have chosen, the television should be safe, however, I highly recommend installing a mantel at the required height and then installing the television above the mantel.

from ME asked:
June 6, 2015
My fireplace is too shallow for a fireplace insert. Is it OK to have a mason make room for an insert without taking down the fireplace?
It is certainly possible to build the fireplace opening out in order to house a fireplace insert. You will only need to ensure that any combustible foundation or flooring is covered with noncombustible masonry or cement. You will also need to make sure the flue collar on the unit will not fall directly beneath the lintel, as this would cause issues with venting the insert.

from IL asked:
April 29, 2015
In selecting a direct vent insert to convert our gas-ignited, wood-burning, masonry fireplace to gas-only, do we need to select the largest insert that will fit? Can we select a size or two smaller, assuming we are willing to install the right facing to cover the gap between the insert and the original firebox?
So long as you select a facing that will cover the area between the insert and the masonry opening, there should be no problem with sizing down on an insert.

February 27, 2015
We're interested in a fireplace insert. We have a 1968 house which has an old Superior Heatform Model A fireplace. Is it possible to replace this fireplace with an insert? The original fireplace has a brick chimney. Would we have to completely remove this old fireplace? Also, would we have to remove the chimney and replace it?
I have come across many of these heat exchange type firebox "sleeves" and in almost all cases, the brick firebox behind them was not finished to accept an insert. However, the only way to know for certain is to first remove the existing unit and inspect the interior of the firebox to ensure it was lined with firebrick and the chimney has a metal liner or clay flue in good working order.

from Columbia, MD asked:
February 16, 2015
Do any of the ventless natural gas inserts come with a fan to push out more of the heat?
The vent free fireplace inserts we carry do have a circulating blower as standard. This helps to make maximum effective use of the heat generated by the appliance.

Will the G13600-N fireplace insert work if there is a power outage?
The Napoleon GI3600 is a standing pilot/millivolt style of appliance and will indeed work in the event of a power outage. The accessory blower is the only component that will not operate.

I am doing some construction on a home with a large back porch where we will be installing a wood burning fireplace. It is a covered porch and the fireplace will not be subjected to water. Do I need a stainless steel fireplace insert or a regular steel insert?
By code, a stainless firebox should be installed in any outdoor application that will expose the unit directly to outdoor air. Even if covered, the humidity in the air will quickly corrode a standard sheet metal firebox, requiring it to be replaced within 5 to 8 years on average.

from Cherokee, AL asked:
January 11, 2015
Can I add insulation to the outside of this unit to make sure that I do not catch something on fire? My walls inside and out are cypress. I need to make sure it does not get too hot.
As long as the back, bottom, top, and sides of the unit are installed maintaining the clearances that are specified in the manual, no additional insulation will need to be used around the fireplace. Adding insulation could actually stifle air flow and cause an overheat situation. The unit will be designed to maintain safe temperatures, as long as the clearances listed in the manual are maintained.

from Hampshire, IL asked:
December 31, 2014
Can a fireback be used in a fireplace insert?
It is not recommended to do so. The high heat generated in a fireplace insert can warp and damage the casting, as a fireplace insert will not have the dilution air pulled in that an open fireplace will.

from Fountain, CO asked:
November 15, 2014
Can I replace my gas insert with a pellet burning one?
As long as your fireplace has the dimensions to house a pellet insert, installation of one should not be a problem. Pellet inserts use a different venting system than gas models. As such, the existing venting will need to be removed and a stainless liner installed for the pellet insert.

from Hollisgton, MA asked:
September 23, 2013
How would you install the insert into an existing fireplace? What kind of liner is required?
Wood burning and gas inserts alike will usually use a decorative metal surround to cover any additional space between the insert and the fireplace opening. The insert would simply be pushed into position, then the liner can be dropped down the chimney flue. Lastly, the surround can be attached.

Can I add a wood burning insert to my fireplace without losing my existing glass doors?
Unfortunately, no. All wood burning inserts require the removal of any existing door enclosure, as the insert will have a sealed door of its own that must be readily accessed. The insert must also be able to readily radiate heat to the room. Your factory door enclosure would likely prevent this to a degree.

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

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