We recently purchased a new home. It has one of your gas fireplace inserts, but we are having trouble lighting or turning it on. Can you tell me where the lighting instructions would be online?
By Collin C. - NFI Master Hearth Professional on November 19, 2012
Answer:We are an independent online retailer and sell several brands of gas fireplace inserts. As such, I will require the manufacturer's name and model number of the fireplace in order to provide the proper lighting instructions.
Most units will have a build plate near the gas valve which will have the model information.

What advantage is there between a gas (ventless/propane) fireplace insert versus ventless gas logs? I have a real fireplace with flue tile (damper on top of chimney). Will the insert help cut further loss of heat escaping from the room?
I am presently in the market for a replacement for propane gas logs that I've had for years. I am extremely interested in the electronic remote that allows you to not use the pilot light.
By Collin C. - NFI Master Hearth Professional on November 27, 2012
Answer:A ventless gas fireplace insert will hold an efficiency advantage over gas logs for a couple of reasons. First, the insert is completely sealed. As you mention, this will prevent any heat from the room escaping up the chimney and will ensure all heat produced by the unit will enter the room.
Second, you can equip the insert with a circulating fan, which will help to speed heating of the immediate area. The only downside to the inserts we carry is that they all use a standing pilot as opposed to the ventless logs that have an option for electronic ignition.

Is size based on the depth of an existing fireplace or its width?
By Tyler M. - Fireplace Specialist on January 2, 2013
The size feature on the search menu for these inserts is based on width. For our best recommendation for a gas insert, please reply with your preference between direct vent and vent-free, as well as your full fireplace dimensions (front width, rear width, depth, opening height).
Also, please advise if your existing fireplace is a brick/masonry unit or a manufactured (metal) unit. For more information, please see our Fireplace Insert Buying Guide

Are there any efficiency measures that we can look at to compare models? Should I look at unvented units?
By Tyler M. - Fireplace Specialist on November 6, 2012
Yes, efficiency information is usually documented on each insert's item page, under the "Item Description." Vent-free inserts always provide 99.9% efficiency, as the heat generated by the fuel is not lost through a chimney.

I'm confused as to the different types of vents. I would be installing this into an existing fireplace. Which vent type is best?
By Tyler M. - Fireplace Specialist on January 3, 2013
Answer:If you are looking at installing a full-bodied direct vent insert, you will need an appropriate, compatible vent kit. In most cases, this would be two co-linear (side-by-side) aluminum liners.
By Craig from Southern CA on January 21, 2013
What measurements do I need from my existing fireplace to choose a gas insert? Will it vent through the existing chimney? Will I need to modify the chimney? Anything else you can think of?
By Tyler M. - Fireplace Specialist on January 21, 2013
Answer:If you reply with your fireplace's front (opening) width, the rear width, the depth (front to back) and the the opening height, we can advised on properly-sized inserts. In some cases, you will be able to vent through an existing chimney, depending on its size. Is your existing fireplace a brick/masonry unit or a manufactured (steel) unit? If it is a manufactured fireplace, please reply with the manufacturer and model information.
By Rachel from Staten Island, NY on November 11, 2012
We own an old home and are eager to use gas inserts to utilize the old fireplaces. We know the chimneys have blockage with old broken-in bricks etc and that they haven't been used in many a year. What are the benefits and differences in vent-free and vented gas fireplace inserts?
By Collin C. - NFI Master Hearth Professional on November 12, 2012
Answer:Vented fireplace inserts will have a sealed firebox that will draw combustion air from outdoors, as well as vent its exhaust gases. Most of these units do this by use of a pair of 3-inch flexible aluminum liners and a special termination. The chimney system would need to be cleared and deemed safe to use this type of insert. Vented appliances can be used for an extended period, without affecting the quality of room air. However, these units are not as efficient as a vent free unit.
Ventless fireplace inserts are completely self-contained and would not require the use of a functioning chimney system. These models use air from within the room for combustion and vent all of their heat directly into the room, making them very efficient. However, because these units use room oxygen, they are limited on run time. They can also have a negative affect on air quality over time and will add moisture to the air while operating. If you have large rooms with high ceilings, this will not be as much of an issue.
By Greg from USA on November 9, 2012
Hi! I am the manager of a condominium complex with 64 units. We are thinking of converting all of the units to gas fireplace inserts. I have 2 questions for you:
1. Can these be converted to propane, and is there an additional charge to do this?
2. Also, if we purchase 64 units, would there be a discount?
on November 9, 2012
Answer:We sell a variety of gas inserts, and all are available for use with propane. Some units do have an additional charge for a propane conversion kit, while others do not. As for a quantity discount, we may be able to offer some kind of price break for an order of that size. Please reply with a model number and a shipping address and we will let you know what we can do. We look forward to your response.
By Lori on November 9, 2012
I want to install a glass pebble fireplace in my existing hearth. I already have the gas connection, but don’t know where to start looking for the actual gas element. I am finding the glass and the inserts online, but this is a brick fireplace with a gas hookup that I want to modify.
on November 9, 2012
Are you interested in simply a glass burner assembly? These are very similar to a gas log set but instead of a log assembly and grate, they use glass ember fill. These units simply need a gas line to complete installation. Please follow the below link to check out our collection:
Gas Fire Glass Sets
If you'd like to reply with your fireplace dimensions and your preference for control option, we'd be happy to match up the proper size set for you. We look forward to your reply.
By Becky on November 9, 2012
Just bought a condo which has two wood fireplaces. Haven’t had them checked out yet for chimney safety, but know I would like to have natural gas in at least one. I don’t know what the website means with ‘direct vent’, ‘small vent’, vent free’, etc. I know I want a blower on it to take in cooler air from the room and to blow out warm air into the room. What should I look for?
on November 9, 2012
Answer:Are the fireplaces in your condo manufactured (metal) or masonry? Depending on what is currently installed, I may be able to suggest a fireplace insert that can be installed into the current unit or you may have to consider other options.
Direct vent fireplaces have a sealed glass window across the front and draw all combustion air from outdoors. Likewise, they vent to the outdoors with the same size chimney liner.
Vent-free units have no venting system at all. They utilize air from the room for combustion and vent all heat back into the room. They are able to do this by limiting their BTU output and utilizing very sophisticated burner assemblies. Even so, these units are not recommended for smaller spaces, as they can reduce oxygen levels in the room and add unwanted moisture.
B-vent (natural vent) units use the same type of piping as a gas furnace or water heater. They vent exhaust to the outdoors through this 3- to 6-inch piping system and draw air from the room for combustion. These units are not as efficient as the other two categories and are largely for aesthetics.

Do you carry corner units?
on November 9, 2012
While we do not carry any corner gas inserts, we do have some corner model zero clearance manufactured gas fireplaces. Please see the "Gas Fireplace" section of our page here:
Once there, please use the search bar on the left-hand side and select "Corner Fireplace" under the "Fireplace Type" category.
Please let us know if you have any additional questions.
By Andrea on November 9, 2012
My 36-inch, vented gas fireplace is over 10 years old and no longer works. My plumber said it is not a gas problem and thought it may be electrical. Do I need a new fireplace or just an insert?
on November 9, 2012
Answer:If your plumber believes the problem to be electrical, it may be an issue with the gas valve itself. This is often the only component that requires electrical power to operate.
By Isaura on November 9, 2012
I am interested in a natural gas fireplace insert. I do not know much on inserts and would like to know what do I need to be aware of and what are the measurements I need. The opening is about 34"Wx 31"H and the depth is about 25" measured from the bottom, if measured from the top of the opening it is about 15". The width measured from the back is 25". The rear width is about 24.5".
What would be the size and specifications I should be looking for? The room where the fireplace is, is about 24x12 with an 8' opening/hallway that leads to the kitchen which is 20x11.
on November 9, 2012
Most of our inserts will list the minimum dimensions necessary to fit on the item description portion of their page. For example, this model:
This unit requires 30.5" of front width, 19" of rear width, 21.375" of height, and 14.25" of depth. Another model that you may consider would be this unit:
Fireplace Insert 2
Either of these inserts would fit into your opening and provide sufficient heat for your square footage mentioned.
By Bob from Cottonwood, AZ on April 7, 2013
I'm interested in installing the Napoleon LHD50 See Thru Fireplace on the wall between my living room and bedroom. I intend to place a TV over each side of the fireplace. Is that something I'll be able to do with this unit? And does this fireplace come with a light package, blower, trim kit for both sides and twigs that I can use as an inside package?
By Collin C. - NFI Master Hearth Professional on April 8, 2013
Answer:While a television can be installed above the fireplace, the manufacturer strongly advises that the television be recessed into a wall enclosure. Even with a mantel between the fireplace and the television, high levels of heat can still reach the television and cause damage.
The unit does indeed come standard with accent lighting that accentuates the glass media in the fireplace. Because of the smooth faced nature of the fireplace, a circulating blower is not an option. The ceramic twig accessory is available as a $45 option for this unit. The unit does not come with trim as standard and will need to be added, should you wish to get the look shown on the website. The available surround colors can be seen under the accessory tab on the unit's item page.
By Dan from Minneapolis, MN on March 5, 2013
We have an existing see-through (living & dining rooms) wood burning fireplace. Can we get a gas insert for it? Will it be visible from both rooms?
By Tyler M. - NFI Certified Specialist on March 5, 2013
We do not carry any multi-sided inserts at this time, though we do have some see-thru zero clearance gas models. If you have a brick/masonry fireplace, you can install one of these inside your existing fireplace if there is enough room for the unit itself and the required venting components. Please see our full selection below:
By Greg from Lake Luzerne, NY on April 29, 2013
Do you have an efficient gas insert(furnace) that is also highly efficient?
By Collin C. - NFI Master Hearth Professional on April 30, 2013
Answer:Both the direct vent and vent free gas inserts we carry are very efficient. The direct vent range from 75 to 85 percent efficient, while the vent free are 99 percent efficient.
By jerry Bartho from Minnesota on February 21, 2013
Is it difficult to insert a gas fireplace into an existing wood insert fireplace? Who runs the gas line?
By Collin C. - NFI Master Hearth Professional on February 22, 2013
Answer:As long as the gas insert is sized properly to the wood-burning fireplace, installation is fairly straightforward. Gas lines for the unit are generally run by a plumber. In some cases, the same plumber can complete the entire installation, if they have prior experience with this type of appliance. Otherwise, a licensed contractor would need to complete the installation.
By Phil from Florida on November 20, 2012
I am renovating a 1910 late-Victorian home that has at least three fireplaces, it may be four. The original cast iron inserts have been removed. I suspect these inserts were originally made to burn coal since bottle gas was not available until the 1930's. The fireboxes appear to have been lined with firebrick.
These fireboxes are relatively small: only 7.5" deep, 28" high, and 21" wide in the front. They taper inward from the front to a back width of just 18". The dimensions vary among the three, depending on the firebricks. Can I remove the firebricks to provide clearance for a cast iron gas insert? What is the smallest dimension gas stove/insert you sell? The chimneys are open so I would like to use direct vent.
By Tyler M. - Fireplace Specialist on November 21, 2012
Unfortunately, you will not be able to install a direct vent insert into these fireboxes. Removing the brick will disallow installation regardless of the increased dimensions, as inserts are designed to be housed within a brick/masonry fireplace.
The only direct vent option we have for your fireplaces would be a freestanding direct vent stove
that can be placed in front of your fireplaces and piped up through your existing chimneys.
By Kip from Stanwood, WA on May 3, 2013
Is it possible to get a natural gas version of the Innsbrook Large Direct vent gas fireplace insert?
By Tyler M. - NFI Certified Specialist on May 6, 2013
By ed hunt from Los Angeles on November 24, 2012
What do you mean by "direct vent" in the context of a small gas fireplace insert? What are the venting requirements? The existing brick chimney is about 8"x 8".
By Collin C. - NFI Master Hearth Professional on November 26, 2012
Answer:Direct vent fireplace inserts utilize outside air for combustion, as well as venting their exhaust gases to the outdoors. This is accomplished by the use of a pair of 3 or 4 inch diameter aluminum liners. These will be routed up the chimney, side by side, and attach to a termination cap that will cover the top of your masonry chimney.
Because one liner carries air and the other vents exhaust, the front of the unit is sealed with a solid pane of glass and has no interaction with the air in the room. Because of their efficiency and venting design, these are the most popular style of insert we sell.
By Doug from San Jose, CA on December 10, 2012
I have a majestic mr42a with chimney, and I am looking for a gas insert with blowers. The dimensions of the glass opening are 42" x 21.5". What are my options?
By Collin C. - NFI Master Hearth Professional on December 10, 2012
A couple of the best options for this type of manufactured fireplace are the Innsbrook Small Direct Vent Gas Fireplace Insert
or the Napoleon GDIZC Direct Vent Gas Fireplace Insert
. Both units are small enough for installation into this manufactured fireplace, while leaving room for you to attach and route the flexible venting up the chimney.
Both inserts also offer trim to finish all four sides, assuming there is a rise between the hearth/floor in front of the MR42A and the interior of the unit itself.
By Hina from NJ on March 12, 2013
I want to convert my wood burning fireplace in to gas. What sort of gas insert do I need? Is there anything I need to be aware of when selecting an insert?
By Tyler M. - NFI Certified Specialist on March 12, 2013
The biggest consideration you have is the feasibility of fitting a full-bodied insert inside your existing fireplace versus the option of simply installing a gas log set inside (burner and logs). First, please confirm in your manual that the model has been approved for a gas insert to be installed within it. Next, get the full dimensions of your fireplace (opening width, opening height, rear width) as well as the diameter of the flue collar opening and its location relative to the front face of the fireplace. For more information, please see our Fireplace Insert Buying Guide
By John from Reno, NV on January 26, 2013
We received a Coleman model 36ECMII as a gift. It has glass bi-fold doors, can you please tell me if this will take fire wood or is it gas only?
By Collin C. - NFI Master Hearth Professional on January 28, 2013
Answer:The 36ECMII was a long running fireplace model that was designed to be used for wood burning primarily. However, it does have provisions for installation of a gas line. As such, a gas log lighter or set of gas logs can also be used. The unit must be vented using Class A FMI brand pipe. Either the 8DM or 8HT series of piping can be used. I will be happy to assist with any venting needs you may have.
By Max from Livermore, CO 80536 on January 17, 2013
I am considering installing a fireplace firebox to use with a propane gas log set and possibly a blower. I understand "ventless" are not legal in our area. Would I need just a vented insert or what. What diameter is the exhaust pipe? I plan to custom build in a framework around the unit.
By Tyler M. - Fireplace Specialist on January 17, 2013
As it appears, you do not have an existing fireplace in which to install an insert, so you would have two options. The first would be to purchase a manufactured, zero-clearance woodburning fireplace with the appropriate class A chimney pipe, then install a propane vented gas log set. The other would be to buy a zero-clearance direct vent gas fireplace, which would consist of the firebox, the burner and the gas log set, plus the appropriate vent kit. Some direct vent fireplaces can be vented horizontally straight out from the rear of the fireplaces, while others require a vertical rise but then can be turned horizontally and terminated on an exterior wall. Both of these options would have provisions to add a blower for added heat circulation. If you are looking for a dependable secondary heat sources, we recommend going with a direct vent fireplace. Please see our full selection below:

By Sandi from Mason City, Iowa on January 18, 2013
I have a corner fireplace, 2 sided, front and side view, wood burning, with a natural gas lighter. I would like to change it to a gas fireplace, I need the glass sides and the burners. Do you have any ideas? I currently have the screens, but want the glass.
By Collin C. - NFI Master Hearth Professional on January 18, 2013
Answer:I will be happy to look into the availability of glass doors and gas logs for your fireplace. Please provide the manufacturer name and model of the fireplace so I may research this further. There will likely be a build plate on the smoke shelf of the unit or in the void space beneath the fireplace floor that will have this information.
