I currently have a B vent wood burning insert that leaks a lot of cold air . I want to replace it with a vented gas insert but what keeps cold air from infiltrating the unit from the vent when not in use? I'm going to use it very sparingly, should I just buy a non vented one because I'm more concerned about air infiltration.
By Collin C. - NFI Master Hearth Professional on January 28, 2013

If the current unit is replaced with a direct vent fireplace, the combustion chamber would be sealed and would eliminate any cold air intrusion from the fireplace. Vent free is indeed another option that could also be considered. Do you plan on removing the current unit complete and replacing it or are you looking for a true insert that could be installed into the existing fireplace?

I am installing a gas log insert in my wood burning fire place. Can the controls be mounted inside the glass, or do I have to find a way to put them outside the fireplace walls?
By Collin C. - NFI Master Hearth Professional on September 11, 2013

The control valve itself can be located within the fireplace glass enclosure, as they are designed to deal with the heat. However, if you utilize a remote ready set, the remote receiver will need to be located outside of the glass, as it can be damaged by overheating.

Is there any regulation regarding how close to a window you can place a gas(propane) fireplace? I would want a vented one as I hear too many issues with non vented.
By Collin C. - NFI Master Hearth Professional on December 11, 2013

By national code for direct vent fireplaces, the edge of the vent termination can be no closer than 12 inches to a door or a window. Most terminations are approximately 12 inches across, so the center line of the vent passing through the wall would need to be approximately 18 inches from the edge of the nearest door or window.

We are remodeling our basement and would like to install a fireplace. We don't know much about them but the space is about 900 square feet. What would you suggest?
By Kevin E. on December 2, 2014

For your space and location, I would recommend a unit that is capable of producing around 30,000 BTU. A vent free fireplace would likely be the easiest unit to install. These units require no venting and can be built into just about any wall. Something like our 32" Vail fireplace should serve you well. Vent free units do require a steady supply of make up air and are known to add condensation back to the room, though. An alternative would be a direct vent fireplace. These units do require venting but do not add any condensation to the room nor do they draw any combustion air from the room. Their venting system provides all combustion air and sends all exhaust to the outdoors. Our Empire Studio is a popular example in this size range.

Does an indoor/outdoor fireplace give off heat on the outdoor side?
By Collin C. - NFI Master Hearth Professional on June 10, 2013

An indoor/outdoor fireplace will indeed give off a limited amount of heat on the outdoor side. However, the unit is primarily intended to viewing aesthetics, as the sealed outdoor conversion window limits a great deal of heat from being transmitted by circulation. Only radiant heat will make its way to the immediate area.

By Lauren from New Jersey on November 29, 2013
I am looking for an enclosed direct vent gas unit to replace my current old Superior wood burning unit. The opening size is 38" wide x 31" high. Is it possible to use one that is 36" wide in this space? This seems to be a much more popular size with many more choices.
By Collin C. - NFI Master Hearth Professional on November 29, 2013

It is indeed possible to use a 36 inch unit in your application. This size is indeed one of the most widely produced and most popular sizes. It may be necessary to reduce the framed opening, once the old Superior unit has been removed, but this will depend on how much of an overall size difference the new unit will have.

By Clyde from Gainesville, GA on August 9, 2014
What is the least expensive gas fireplace you have for installation on a screened porch?
By eFireplaceStore on August 11, 2014

Our lowest cost complete system for an outdoor application will be the FMI Alpine Outdoor 36 in. Natural Gas Vent Free Fireplace System. We do have some vented boxes that have a lower initial price, but they require addition of the chimney and gas logs, putting them at a higher overall cost than this vent free product.

By Michelle from Queens, NY on March 1, 2013
Can I have a vented fireplace not on an outside wall, but vented to the outside side of my house , which has vinyl siding? Where I live, can I have a vent free fireplace? Which type gives off more heat?
By Collin C. - NFI Master Hearth Professional on March 1, 2013

A direct vent fireplace can be installed on an inside wall and horizontally vented, however you will need to ensure that you have space in the adjacent area for a venting system to be enclosed in a chase wall.

In regards to the vent free fireplaces, contact your municipal code office to verify that they can be used, as state and local guidelines can differ.

By Chris C. on June 18, 2014

We do indeed sell keys with extended length stems, but I will need to know the shape and size of the gas valve stem to advise as to whether or not they will fit. Do you happen to know this information? Please advise.

I am looking for a gas fireplace for my bedroom that is direct vent with accent lighting. Do you have any besides Napoleon?
By Collin C. - NFI Master Hearth Professional on September 23, 2013

A unit that should suit your needs well is the Monessen Belmont 36 Inch Clean Face Direct Vent Signature Command Fireplace - Natural Gas. This unit features a BTU output that would be on par for a bedroom and offers an optional light kit that is floor mounted for a natural look. While the flue collar is top vented, it can be directed rearward for a through the wall application as well. Please let me know if you have any questions.

By Stan from NY on November 5, 2014
Can outside oxygen be routed to a ventless gas fireplace as opposed to using the household oxygen?
By eFireplaceStore on November 5, 2014

This will depend on the appliance. Some vent free fireplaces will have the chassis provisions for an outside air kit to be used, while others do not. If a vent free appliance does not have provisions for outside air, it should not be modified to do so.

I'm looking for a contemporary fireplace, natural gas, with logs. Any recommendations?
By Collin C. - NFI Master Hearth Professional on September 13, 2013

Clean face fireplaces offer a more contemporary look, but still have the traditional log sets available. A popular model we offer is the Napoleon BGD36CFNTR Clean Face Direct Vent Gas Fireplace - 36-inch. The clean perimeter can be likened to a picture frame and gives the face of the unit an uncluttered look. Another popular unit that features a larger opening is the Napoleon HD35 Direct Vent Clean Face High Definition Gas Fireplace. The taller opening and high definition burner put focus on the log set, while keeping the same clean face lines that help the unit blend in with contemporary decor. I will be happy to answer any questions you may have about either model.

By Ella from CA on August 16, 2013
If I am installing a direct vent fireplace on an interior wall, does that mean I need a top vent as opposed to a back vent?
By Tyler M. - NFI Certified Specialist on August 19, 2013

Yes, likely you will need to run the venting vertically over your roof. Please check with the manufacturer for specific venting installation information.

By Brent from Stafford, va on September 1, 2013
Looking for a direct replacement for a BCF-3885 wood burning insert. I would like a gas insert instead. Do you have any that are close in size?
By Collin C. - NFI Master Hearth Professional on September 3, 2013

One model we carry that is an almost perfect match to your current fireplace is the Napoleon BGD36CFNTR Clean Face Direct Vent Gas Fireplace - 36-in.. This model could serve as a good replacement with minimal reframing necessary from removal of the current model. If you require a model will higher heat output, I will be happy to research other models that may work for you.

By Melissa from Phoenix on November 24, 2013
I have the original gas burner/pipe (not sure what its called) and attached tray from the previous home owners. We were then given a grate and vented gas logs from my parents. From the pics below, the fire obviously looks fake. What materials can I put underneath the grate where the gas flows so it looks real? Basically, do you have any suggestions on how to make this fireplace look better without spending too much money?
By Collin C. - NFI Master Hearth Professional on November 25, 2013

The design of your burner pan calls for use of either sand or vermiculite to help diffuse the flame, then glowing embers can be poured across the top of the material to give a more realistic appearance. If you are using liquid propane, the pan should be filled with Real Fyre Vermiculite Granules - LF-15. If you are using natural gas, it should be the Real Fyre Select Sand - CS-10. After either product is used, the system should be finished out with the Real Fyre Ember Glow - EM-1.

What is the difference between Linear and Direct vent fireplaces? I am looking to add one to my new home and would like it to be a back up heat source.
By Will M. on July 10, 2014

"Linear" is a style of fireplace, while "direct vent" is a type of fireplace that has a tempered or ceramic covered covered opening and utilizes a coaxial or co-linear venting system for combustion air. One pipe is the exhaust while one pipe is the intake. It's typically a "pipe within a pipe" or coaxial system. Basically, you can have a direct vent fireplace that has a linear style.

By Scott from Acworth, GA on November 13, 2014
Can I burn wood in a direct vent fireplace insert?
By eFireplaceStore on November 13, 2014

Direct vent gas fireplaces are designed to burn gas only. The design of the firebox and the venting system is not conducive to burning wood.

Do you make Conner vent free natural gas fireplaces?

By Collin C. - NFI Master Hearth Professional on February 10, 2014

While any of our vent free units can be positioned on an inside corner at a 45 degree angle, we do not currently offer a vent free setup that is designed to be built into an outside corner. A direct vent model that we offer in this configuration is the Majestic 36 Inch Designer Left Corner Direct Vent Gas Fireplace with Signature Command Controls - Natural Gas.

By Bernadette on November 9, 2012
Is it possible to convert the old fireplace in my 1889 house to gas and keep the old look and style?
on November 9, 2012

This will depend entirely on the size and condition of the existing fireplace and its associated chimney. There are many specialty log systems and gas coal baskets that are intended for smaller fireplaces that previously burned wood or coal. What is the opening size of your fireplace and is the chimney in good working condition? Please advise.

By Michael on November 9, 2012
I'm looking for a direct vent gas fireplace, something low height and wide that can be down-vented (power vented). Have you any?
on November 9, 2012

We do have a couple of linear direct vent units that can be power vented. Please see them below: Direct Vent Fireplace 1 Direct Vent Fireplace 2 Here is the power vent terminal for these units, and the appropriate adaptors: Power Vent Terminal Adaptor LHD45 adaptor: Power Vent Terminal Adaptor LHD50 adaptor Power Vent Terminal Please let us know if you have any additional questions.

By Clyde on November 9, 2012
We have a wood burning fireplace in our home. We are planning to remodel the family room. One of the things wrong with the room is that the fireplace is not in the center of the wall and it is not eye-appealing. The face of this fire place measures: 40" w x 38.5" h. The inside measures: 29" w x 19" h. I would like to put in a smaller natural gas insert into this space. The chimney is fireplace sis vent pipe. Is this feasible to put a smaller fireplace into this opening?
on November 9, 2012

You would indeed be able to install a natural gas insert into your existing fireplace, given that it is rated for use with an insert. Of course, installing an insert into this unit would not correct the off-center concern that you are experiencing with your current fireplace. Are you interested in a direct vent insert or a vent-free model? Please follow the below link to view a direct vent model that would work in your application. Direct Vent Fireplace Of course, if you opt for direct vent, new venting would need to be installed along with the insert. Please let us know if you have any additional questions.

By Dan from Reading, PA on March 4, 2013
I am looking to replace an old vent free corner mounted LP operated fireplace. The opening on the existing surround (cementaceous board with a brick face) is 34 inches wide by 28 inches high. The mantel should have adequate space for a 32 inch model. I could not find remote operated information on most of the product descriptions, but would like to have that option. The primary purpose of this fireplace is occasional usage and power outage backup heating capability. Could you please direct me to fireplaces that fit this description ?
By Kevin E. - Fireplace Specialist on March 5, 2013

We do indeed have a unit that should work well for you. Our Monessen DIS33 fits both your dimensional criteria and your desire for a remote.

By Antoinette on November 9, 2012
What is the difference between natural vent and direct vent? We want to vent it out through a PVC pipe instead of a chimney. I am interested in using a gas fireplace to heat a 1900 sq ft. basement. I would like it to be efficient and pretty. We have natural gas. We want to also have a thermostat and fan. Can you also explain the benefits and concerns of pilots vs. electric start or some other starter? Wall controls are also helpful. Can you let me know what else I would need?
on November 9, 2012

We get this question often, and you can see it explained in complete detail in our Gas Fireplace/Stove Buying Guide: Gas Fireplace/Stove Buying Guide. Unfortunately, with both types, PVC pipe cannot be used. Natural vent units require Type B gas vent pipe, whereas direct vent units require coaxial pipe (pipe-within-a-pipe). The application you have calls for a large, upscale unit to provide this kind of heating. Given that you need heat, you will need to go with a direct vent unit, as natural vent/B-vent fireplaces are very inefficient. Please see a few recommendations below: Direct Vent Unit. Direct Vent Unit. Direct Vent Unit. The first and third units on that list will provide the most heat. All three units have electronic ignitions with a battery back-up. The advantage of this is there will be no standing pilot, and therefore no unused gas expenditure. The only items required for installation that are not included will be the venting pipe, which are all available on each item page in the "Venting Components" tab.

I'm looking for direct vent corner fireplace to also be used as TV stand using propane. Any suggestions?
By Collin C. - NFI Master Hearth Professional on May 12, 2014

We offer several models of direct vent fireplaces that can be built into a corner, using a prefabricated or site built mantel enclosure. To verify, are you looking for a mantel such as the Empire EMBC2S Corner Wooden Mantel Cabinet with Base, which would allow you to place a television on top of the cabinet? Please advise at your convenience.

How does one clean the brass or gold plating on the front of the fireplace? I am afraid to use anything too harsh.

I am looking for a B-Vent, Natural Gas unit. The measurements of my area are 40.5" W x 38.75" H x 26" D. I am looking for one with or without a blower.
By Collin C. - NFI Master Hearth Professional on December 2, 2013

A model that we offer that is very close to your framing width and height limitations is the Keystone Deluxe B-Vent Louvered Gas Fireplace - 36". The unit has a louvered face, allowing the ability to add a blower to circulate heat, if you wish to do so.

By Chris on November 9, 2012
We have a propane vent-free fireplace by Kingsman. The fireplace was already in the house when we bought it new, so we were the first to use it. From day one it has made a hissing sound when the burner and flames are on. We had someone come out to look at it and he said that is “normal!" It was not the pilot light, nor the burner, not the flex hose or the air coming into the house from the gas line. I have seen other people’s fireplaces and have NEVER heard a hissing. Could you possibly tell me what it might be? Could the brand we have be “cheap”, not well made? We are also considering purchasing a new insert, but have no idea which manufacturer is best. Any guidance would help - websites or someplace we could go for further research would be helpful.
on November 9, 2012

I apologize for the issues you are having with your fireplace. Kingsman usually makes good quality products and I have heard little negative feedback about them. Hissing is usually caused by high gas pressure or a kink in the supply line, but it sounds like you have already had the unit thoroughly checked over. The Monessen and Napoleon lines that we carry are both good quality lines that offer a considerable bang for the buck. Being vent free, I am assuming that this unit would be intended primarily for heat.

By Gerry from Calgary, Alberta on April 5, 2013
I have an LHD50 Napoleon FP, I would like to purchase a fan assemble to direct warm air in the cavity in and around the FP. I have lots of void space behind and on the sides and would like to pull air from the room and push it thought this space to warm up and discharge back into the room. Could you recommend a kit to use? The LHD has plug in for a fan on the control module, can I use this to control? If I can, will I be able to get a variable speed?

Thanks in advance for your help.

By Collin C. - NFI Master Hearth Professional on April 8, 2013

Per the manufacturer, the LHD50 does not have provisions for a circulating blower to be used. The control module does indeed have an A/C adapter on the control module, but this is intended for use if the fireplace is equipped with a power vent, which aids in drafting issues.

It may indeed be possible to pull heated air from the cavity surrounding the fireplace by installing a custom plenum and fan, but this would need to be something fabricated by a contractor on site.

By Don from Lake Oswego, Oregon on June 2, 2014
We are building a home and want a linear gas direct vent fireplace in our bedroom but do not need it for heating purposes but mainly for the ambiance. Do you have a recommendation that would fit our needs?
By eFireplaceStore on June 2, 2014

For your application, a unit such as the Napoleon LHD45 Linear Series Gas Fireplace will be an excellent choice. This fireplace offers the clean look of a linear chassis and good flame presentation, but also has the ability to be equipped with a hot air exhaust kit, which vents a good portion of the accumulated heat to the outdoors, preventing it from overheating the room. If the appearance of this unit suits your needs, I will be happy to discuss its aspects further. Please advise at your convenience.

By Kristina from Arkansas on December 26, 2012
Can you place a flat screen TV above a vent free fireplace?
By Tyler M. - Fireplace Specialist on December 27, 2012

There is no clear answer on this; it depends on the fireplace model (BTU output) and how your television is installed (recessed, wall mount, etc.). The majority of heat from a vent-free fireplace comes out right at the top of the opening, going upward. As such, vent-free fireplaces are equipped with hoods to help deflect this heat.

Further, some units have the option to add a blower, which will help push some of that heat out into the room. Fireplace manufacturers do not test or list their models for use underneath any television, due to the sheer volume of flat screen/plasma/LED models on the market.

Our best recommendation is to put the television as far above the fireplace opening as possible and to recess it into the wall (if possible), and check for an extended hood option on the vent-free fireplace for additional help in deflecting the heat.

By Lynn from Minneapolis, MN on September 13, 2014
What type of gas fireplaces are approved in Minnesota? Would they allow direct vent fireplaces?
By Tyler M. on September 15, 2014

We are not aware of any restrictions against direct vent gas fireplaces in Minnesota, but there are indeed some areas that prohibit the installation of vent-free gas appliances. We recommend contacting your local building code enforcement office for more information.

Can a Majestic SC36 with gas insert be used for wood burning by removing the gas unit?
By Tyler M. - Fireplace Specialist on November 28, 2012

Yes, the SC36 is a wood-burning fireplace that is designed to burn wood. As such, if all gas components are removed, you can indeed burn wood in the unit, provided the Class A chimney system is in good shape.

By Barb dion from Milwaukee on October 22, 2012
I am looking at an old home with an artificial fireplace. I would love to make this gas-fueled because it's a perfect place for it. Would this be possible? Could I use the existing space?
By Kevin E. - Fireplace Specialist on October 23, 2012

Is your intent to completely remove the existing fireplace? If so, then yes. It would be absolutely possible to frame in a new fireplace in place of the old unit and run the necessary vent pipe for this new appliance. If you're planning for a direct vent fireplace, venting could be as simple as terminating horizontally right through the exterior wall.

By John from Hopatcong, NJ on October 2, 2013
I like the look of a linear gas fireplace like the Napolean LHD50, and plan to install a unit like this in a new construction house. I have a direct vent already in my plans. My concern is not having a blower unit which really helps with the heat. Do you have any suggestions?
By Tyler M. - NFI Certified Specialist on October 2, 2013

The Napoleon LHD50 direct vent fireplace does not feature a blower, but it has a BTU rating of 30,000, which is a good amount of heat (suitable to heat approximately 800 square feet). We do have another large linear direct vent fireplace that can be equipped with an optional blower--the Majestic 60" Echelon unit. That model is actually a bit smaller than the LHD50, with a viewing area width of 47 7/8", but it has a more powerful burner--up to 45,000 BTUs for natural gas (40,000 for propane), and it can be equipped with an optional blower.

By Bob from Natcyez, MS on March 6, 2014
I have a 42" FMI Zero Clearance vented firebox. The unit was installed in December 2013. Black soot or carbon formed on the logs almost immediately. Is this common?
By Kevin E. - NFI Certified Specialist on March 6, 2014

Have you installed a vented gas log set into this firebox? If so, is your fuel supply natural gas or propane? The sooting may be caused by flame impingement or maladjustment of the air shutters on the burner assembly. Flame impingement can be resolved by re-positioning the logs to prevent contact with the flames.

By Connie from Texas on January 22, 2013
I would like to have a propane vent free fireplace insert with an electric start instead of a pilot light. Is there such a thing? Do you carry them?
By Tyler M. - Fireplace Specialist on January 23, 2013

While finding a propane, vent-free unit with an electronic ignition is rare, we do offer this model:

Napoleon WHVF31 Plasmafire Wall-Mounted Vent-Free Gas Fireplace

This is a wall-mounted unit, and if you need an insert--a unit that slides inside an existing brick/masonry fireplace--we do not have anything with an electronic ignition, all of ours have a standing pilot light/millivolt ignition.

What is the difference between a CDV and a DVB direct vent fireplace and what are the advantages of one over the other?
By Collin C. - NFI Master Hearth Professional on May 15, 2014

Both units use the same fireplace chassis, but the DVB series feature a slightly larger main burner and orifice for increased BTU output. The DVB is also more efficient, allowing it to heat a larger area. If you are primarily concerned with supplying supplemental heat to an area or are looking for a larger flame, the DVB series will be the better choice. If the appearance of a fire is more important than heating capacity, the CDV will be a fine appliance to use.

By Gerry from San Francisco, CA on September 14, 2014
I have a see-thru model and there are time that I would like to close off the fan vent on one side. Do you have a way to do this?
By eFireplaceStore on September 15, 2014

While some see through fireplaces can be partially closed with doors on one side, they cannot be completely sealed. The units require at least some air flow to enter on both sides at all times. Closing one side completely could compromise draft characteristics of the unit and lead to issues with smoke roll out.
