I have a Vermont Casting direct vented gas fireplace free standing. The pilot won't stay on; as soon as I let go of the light button it goes off. Can you help me?

By Tyler M. - Fireplace Specialist on November 5, 2012

Answer:
This issue is often the result of a dirty or partially clogged pilot assembly. In order to clean the pilot, the nut that is threaded to the end of the pilot tube will need to be loosened and disconnected from the pilot assembly.

The nut is approximately two inches down from the end of the pilot tube. The tube can then be cleaned out with compressed air and the nut re-tightened.

I would like to replace a vent free fireplace with a direct vent fireplace. My current framing dimensions are 38" W x 40 3/8" H and 24 1/4" D. The fireplace currently sits in a bump out on the side of the house. Do you have a recommendation of a model that would replace the current one most efficiently (i.e., without a lot of framing changes)? The current surround is granite.
By Collin C. - NFI Master Hearth Professional on November 25, 2013

Answer:
One of the best fits for sizing to your current opening is the Napoleon GD36NTR Direct Vent Gas Fireplace - 36-in., as this model requires a 37 1/4 inch framing width, 38 1/2 inch height, and 14 1/4 inch depth. The unit is also able to be converted to a rear vent configuration, allowing you to install a short horizontal run of vent piping to the outside of the bump out.

I would like to install a direct vent gas fireplace in our master bedroom. The room is 225 sq/ft with a 10' ceilng. I am concerned that the units will put out too much heat. This application would only be used to augment our whole house heating. Is there a unit with a small enough BTU output? What would you suggest?
By eFireplaceStore on October 15, 2014

Answer:
A good option for your installation would be the Napoleon BGD36CFNTR Clean Face Direct Vent Gas Fireplace - 36-in.. This is a low output model that also has the ability to turn down the output to a mere 10,000 BTUs, which is better suited to your room size. Another option is to use a hot air exhaust kit with the unit. This allows you to continue using the unit at full flame height, but exhausts a good amount of heat to the outdoors when the unit is operating, preventing it from heating the room to an uncomfortable level.

For a direct vent gas stove, I have room to install either a rear-vented or top-vented stove. Are there advantages to one over the other regarding efficiency?
By Tyler M. - Fireplace Specialist on January 2, 2013

Answer:
If feasible, it is preferable to go with a top vent model, which you can then run the vent pipe up a short distance (1-2 feet), then elbow out 90-degrees and terminate on an exterior wall.

By Debbie from Santa Cruz, CA on January 7, 2014
I have a small office that is around 350 square feet in California. I am looking for an inexpensive fireplace that will heat but also add ambiance. We currently do not have a heater in the office but we are plumbed for natural gas. What would you recommend as an affordable option? Would I also need some kind of mantel to put it in, or would it be free standing?
By Collin C. - NFI Master Hearth Professional on January 7, 2014

Answer:
One of our most popular options for smaller areas is the Monessen 36 Inch Tribute Clean Face Direct Vent Gas Fireplace - Rear Vent. This contemporary unit is designed for easy installation and can be framed into a wall enclosure or a mantel cabinet. It is designed in both top and rear vent configurations for maximum flexibility.

By Marty D from Bayville, NJ on November 1, 2014
Can you make a recommendation for a direct vent, natural gas fireplace based off of these requirements?

36" max width
top vent
ceramic glass
80% efficient
local code does not allow standing pilot
blower
25k but max input
By eFireplaceStore on November 3, 2014

Answer:
The closest fit for your application will be the Napoleon GD36NTR Direct Vent Gas Fireplace with Electronic Ignition - 36 Inch. This high efficiency direct vent model has all the features you are looking for, although the BTU output is just slightly higher. However, heat output is variable. The unit is shown with an accessory bay front, although there are additional thumbnail photos that show other design options. The accessory blower is the Napoleon Blower Kit with Variable Speed and Thermostatic Control.

By Bill Werner from Grand Island, NE on January 2, 2013
I have purchased a new 6000CL fireplace and want to vent directly out the back. I have 14 inches from the back of the unit to the outside wall. I have been told locally that the draw is not as good as using the top.
By Tyler M. - Fireplace Specialist on January 3, 2013

Answer:
Indeed, a top-vent application that has a one or two foot rise before elbowing 90-degrees through a wall is preferable to a rear-vent. However, in most cases a 14" rear-vent run is perfectly acceptable and should work fine, as the normal maximum straight horizontal run is around 20".

By Craig from TN on March 17, 2014
Can I do a basement install with a direct vent LP gas log fireplace?
By Tyler M. - NFI Certified Specialist on March 17, 2014

Answer:
Yes, a direct vent fireplace can indeed be installed in a basement. If you are horizontally terminating the venting system, the horizontal termination cap will need to be at least 12" above grade (perhaps more per your local code or the manufacturer). We have snorkel termination caps available to help achieve this clearance, if needed for your application. Please let us know if there is a specific model that you have questions about and we can provide more specific information.

I want to replace a wood stove that has an 8" vent collar and want to know if I can replace it with a direct vent fireplace (propane). I prefer wood burning so is there a direct vent fireplace insert for wood?
By Collin C. - NFI Master Hearth Professional on February 19, 2014

Answer:
Direct vent fireplace by design are gas burning appliances. The venting system required for them is an aluminum and galvanized steel combination that is not suited for wood burning. Most wood burning appliances do have provisions for a combustion air intake, but it will depend on the model.

By Lee from MI on October 4, 2014
What is the smallest wall natural gas fireplace that you offer?
By eFireplaceStore on October 6, 2014

Answer:
That would be the Napoleon Torch Direct Vent Gas Fireplace - 12-in.. This model is tall and narrow, requiring only a 14 1/2 inch wide framed cavity for installation.

By Angela from Buffalo, NY on March 3, 2013
I currently have a B vent fireplace. Can I replace it with a direct vent? Do I have to replace the pipe through the roof or use what is there?
By Collin C. - NFI Master Hearth Professional on March 4, 2013

Answer:
A B vent type of fireplace certainly can be replaced with a direct vent model. However, the venting system is different. A larger direct vent pipe, usually 7 inches in diameter, must be used. If you have a 9 inch by 9 inch area to contain the pipe, retrofitting to a direct vent fireplace would be fairly easy.

By Tricia from Dallas, Texas on January 3, 2013
We have 2 direct vent fireplaces in our hi-rise condo. We did the break in period burning totally. However , we are still getting a plastic burning smell, especially after about 1 1/2 hours into burning. Why? It smells bad and I feel it is bad for us to smell.
By Collin C. - NFI Master Hearth Professional on January 6, 2013

Answer:
Per your description, it sounds as if a component such as a wiring harness or remote receiver may be installed too close to the firebox inner chassis and is overheating. Is this smell coming from both units or just one. Also, what material was used to finish around the fireplaces? Can you see any smoke or a haze in the air when burning the unit?

By James from Dayton, Ohio on January 24, 2014
We have an existing direct vent fireplace and are looking at replacement options. We do not like the glass front of the direct vent, but also do not want to remove the wall vent and try and match our exterior masonry. Are there options for this type of situation or are we just stuck with trying to match masonry or with a capped off vent?

By Tyler M. - NFI Certified Specialist on January 27, 2014

Answer:
The only possible way to keep your existing horizontal termination vent is indeed to get a replacement direct vent fireplace, which of course will have a solid glass front. However, the vent may need to be replaced regardless, as many direct vent models require a specific type of coaxial (pipe-within-a-pipe) vent system. Please reply with your existing manufacturer and model information and we can advise on if re-using what you have in place may be possible.

I have a majestic 36BDVR model and I am looking for another. However, I'm unable to find it online so far. Do you know if this is a discontinued item?

By Dottie MacRitchie from Connecticut on November 7, 2012
Which direct vent fireplace has the highest BTU?
By Kevin E. - Fireplace Specialist on November 7, 2012

Answer:
The majority of our direct vent fireplaces average heat output between 30,000 and 40,000 BTU, but this output is directly related to size. Output varies for gas type, as well - either natural gas or propane.


By Verna from Palm Springs, FL on March 22, 2013
I am interested in a direct vent fireplace like the LHD50N from Napoleon. However, I would prefer to run the vent through the existing fireplace/chimney without destroying either one. The top of the existing fireplace is 36". Are there any rear-flue direct vent fireplaces on the market that would allow me to do this? Most that I have seen require close to 4' (from the floor) before a horizontal vent run is made.
By Kevin E. - Fireplace Specialist on March 22, 2013

Answer:
The only options we would have that would be suitable for your application would be something like our Loft Inserts. Of course, these do present a smaller viewing area that something like the LHD50.

By Ed from Murray, KY on June 6, 2014
I am looking for a 36" propane direct vent (top) fireplace in the 30,000 btu range that has a depth of less than 18", has a remote with temperature, a blower all in one package. It would also include a deluxe set of logs with variable flame, back lighting hopefully. What do you have? I am not looking for the highest price fireplace on the market. What I am looking for is a high quality, excellent warranty for a reasonable price. What do you have?

I am going to use it for ambiance most of the time, however if we have an ice storm in winter I can be without electricity for a couple of weeks and the fireplace would be my primary heat source.
By Tyler M. on June 9, 2014

Answer:
We do carry a model that meets all of your needs, with the lone exception that the fireplace depth is 19 7/8" deep; please see the 36" Empire Tahoe Luxury Direct Vent Propane RF Fireplace with Remote Control.

By Lois Tate from Lake Orion, MI on December 30, 2012
I have a direct vent fireplace with no owners manual. I have model no. DVD 32FP30N-1. It is 34" wide by 31" high. Can you help me?
By Tyler M. - Fireplace Specialist on December 31, 2012

Answer:
Yes, you have the Empire Tahoe Deluxe Direct Vent Natural Gas Fireplace. You can see the owner's manual for this unit here: owner's manual

By Amanda from Charlotte, NC on April 29, 2014
We are interested in adding a direct vent fireplace to an exterior wall of our home. We would like to vent it up through a faux chimney, for curb appeal. (It is on the front of our home, so I don't want a vent sticking straight out through the wall.) Is there a minimum height requirement for the chimney, as there is with a standard vented gas log set, or wood burning? Or does the vent just need to clear the top of the chimney, regardless of the height above the roofline?
By Collin C. - NFI Master Hearth Professional on April 29, 2014

Answer:
Direct vent fireplaces require much less vent clearance than standard wood burning or B-vent units. For instance, the vent piping needs only to extend 12 inches beyond a roof that has a pitch of up to 6/12. If you would like to supply the exact roof pitch on the front of your home, I will be happy to advise on the minimum amount of vent pipe that is needed.

By Scott from Philadelphia, PA on October 7, 2014
I am in the initial stages of looking into gas fireplaces. I have questions about "vented, vent-free, and direct venting" fireplaces. Does a direct vent fireplace burn vented logs, and, if so, do they produce the more normal looking flames? I was under the impression that vented logs needed to have a chimney capable of burning real wood logs. Can they be used in a direct vent fireplace?

By eFireplaceStore on October 8, 2014

Answer:
Naturally vented gas logs are the type of vented log set that is installed into an existing masonry fireplace or prefabricated wood burning fireplace. They require a chimney that is in good working order and completely vertical. These log sets typically feature a large realistic flame, but they do not produce much heat and are largely for looks.

Direct vent gas fireplaces will have a sealed combustion chamber, using tempered or ceramic glass. The fireplace will come with a specific log set that must be installed. Like the natural vent logs, a direct vent features a realistic flame pattern, but efficiency is greater and the unit functions as a true supplemental heater. No combustion air is pulled from the room. A coaxial (pipe within a pipe) pulls combustion air from the outdoors and vents exhaust to the outdoors. The venting system can be routed vertically or horizontally.

Vent free fireplaces use a specially engineered burner system and specific log set to ensure a clean burn. These systems do not require a vent of any kind, but they are limited to an output of 40k BTUs. Their very specific log placement lends a less realistic look, as the flames do not directly contact the logs. Vent free appliances create a great deal of supplemental heat, but they do not work well for all applications. People with sensitive noses will likely detect the odor of the burned gas and vent free sets can be an irritant to people with allergies or lung ailments. Vent free appliances also require air from the room for combustion and release moisture back into the room. As such, they work best in larger rooms with high ceilings.

I need a replacement part for the front part of the refractory hearth for FMI Model # GL4100/P. It is the horseshoe shaped part that goes in the front. I also need the blower kit for this model. Do you stock these parts?
By Chris on April 15, 2013

Answer:
After checking with FMI, I was informed that the refractory hearth panel is no longer available through them. He did inform me that the correct blower assembly is indeed still available. The part number for the appropriate blower is VCBK3E.

By Marc from Pennsylvania on September 26, 2013
I just hooked up a VCD36" vented gas fireplace. The pilot lights, but the burners do not. The unit was exposed to dust. Could it just be too dirty? The gas flow is good and other units work.
By Collin C. - NFI Master Hearth Professional on September 27, 2013

Answer:
It is possible that the pilot assembly may be dirty and preventing millivoltage from allowing the gas valve to open. I recommend blowing out the pilot assembly with compressed air. If that does not work, I am happy to call you to perform further troubleshooting.

By Ramona from San Antonio, Texas on November 3, 2012
Is there a direct vent fireplace that can burn wood as well?
By Tyler M. - Fireplace Specialist on November 5, 2012

Answer:
No. All direct vent fireplaces can only be used to burn natural gas or propane.

By Julie from Levittown, PA on November 11, 2013
I have a 36 inch vent free fireplace that I would like to replace with a direct vent fireplace. What do you suggest?
By Tyler M. - NFI Certified Specialist on November 11, 2013

Answer:
As you can see on this category page, there are numerous options for a 36" direct vent fireplace. The best way to offer a suggestion would be to figure what your available dimensions will be after your vent-free unit is removed. This way, we can use your framing space to determine which models may be a good fit for a replacement.

What is the difference between CDV, DVD, and BVD fireplaces?
By Collin C. - NFI Master Hearth Professional on October 14, 2013

Answer:
The BVD series is a unit manufactured by Empire Comfort Systems and is a B-vent model of fireplace. This means that it draws air from the room for combustion and vents exhaust through a aluminum B-vent pipe. These units are largely decorative and offer little supplemental heat.

The DVD series is also an Empire unit and is their basic direct vent design. This model draws air from the outdoors from combustion and is sealed from the room with a pane of tempered glass. The unit can be vented vertically or horizontally and is designed to give supplemental heat.

The CDV series is manufactured by Majestic/Monessen and is similar in build and output to the DVD that is made by Empire. It is also a direct vent unit and offers options to customize its appearance.

By Pam from Barre, VT on September 9, 2014
We would like to buy and have installed a direct vent fireplace to replace a Riannai RHFE 1004 FA heater. The heater was also direct vent, but would a gas fireplace fit where the heater hitched up?
By eFireplaceStore on September 9, 2014

Answer:
This Rinnai heater uses a unique venting system that allows the flue collar to be located in any number of positions before passing it through the wall. There is not a reason why you cannot use a direct vent fireplace in the same spot as the heater, however the location of the vent piping will likely be different. At the very least, the hole in the wall will need to be enlarged, as this heater uses a vent pipe that is much smaller than a comparable direct vent fireplace.

By Kim on November 9, 2012
Does a LHD45N Napoleon direct vent gas fireplace need its own electrical circuit? I have the electrician here and he would like to know.
on November 9, 2012

Answer:
Yes, the Napoleon LHD45 will require electricity to operate, as it uses it for ignition. There is a battery back-up, however, so you will be able to use this fireplace in the event of a power outage. Please let us know if you have any additional questions.

By Kevin on November 9, 2012
I'm looking to replace an old Majestic fireplace that was capable of burning both wood and gas; this thing is probably 20 years old. We still have the old venting pipe from this system and it's approximately 10-12 inches wide . If I were to install a direct vent system to improve efficiency, would this old pipe still be used? Or the new one run inside it? Or an entirely new exhaust installed? I'm just trying to get an idea of what my best plan of action is here. I fully intend to have a professional install the new unit, however, and this consideration may change the location of the new unit and effect the cost of materials.
on November 9, 2012

Answer:
Most likely, you will need to remove the existing chimney system and replace it with the smaller direct vent piping that will be needed instead. While there are some conversion kits that can adapt an existing wood burning chimney for direct vent purposes, there are no kits that are designed to work with Majestic products. The option does exist to leave the Class A chimney in position and line the chimney with the direct vent pipe; however the existing chimney system must be perfectly straight and the termination at the top of the chimney will need to be modified with a site built storm collar to cover the extra space between the direct vent pipe and the Class A chimney pipe. Please let me know if you have any questions about the installation or if I can assist in any other way.

on November 9, 2012

Answer:
We would be happy to send you a quote for these items. Please reply with a shipping address and we will send you a quote as quickly as possible. Also, please advise on any optional accessories you may be interested in, such as a blower, brick liner for the interior of the fireplace, remote control (basic on/off or thermostatic), and anything else you that may interest you.

Hi! My husband and I are looking into a direct vent propane gas fireplace. We don't want to have build on to our home. Are most of these fireplaces with the mantles enclosed totally (except for the vent obviously) within the mantle cabinet?
By Tyler M. - NFI Certified Specialist on August 27, 2013

Answer:
While some of the fireplaces in this category are completely housed within the mantel cabinet, others are utilizing a "flush mount" mantel surround, with the fireplace itself being partially recessed into the wall and the remaining depth being enclosed. Most of our Napoleon direct vent fireplaces have full mantel cabinets available to house the entire unit. For example, the combination below could be used together:

Napoleon BGD36NTR Direct Vent Gas Fireplace - 36-in.

That link is for the fireplace only, the mantel cabinet is this item:

Napoleon Bonaparte Medium Flat Cabinet Series Wooden Mantel

Can I install a direct vent insert into my old fireplace even though my house uses oil, not gas, for heat?
By eFireplaceStore on November 4, 2014

Answer:
A direct vent insert could be installed in your fireplace, assuming it meets the guidelines needed to house one. However, you would need to provide a dedicated fuel source for it, such as an LP cylinder.

By Scott from Newport, RI on March 30, 2013
I'm looking for a direct vent gas fireplace insert with top vent, with 3 or 4 inch exhaust. The fireplace opening is 34" wide in front, 21" wide in rear, 33" height, 15" deep. I'm also interested in a traditional look and glass doors. Which units will work?
By Kevin E. - Fireplace Specialist on April 1, 2013

Answer:
Your dimensions are near perfect for our Medium Innsbrook. Being direct vent, this unit will featured a sealed glass front and dual 3" vents on top. Please note that these units must be installed in a true masonry fireplace.

Direct vent gas fireplaces are very popular because they can be vented without a masonry chimney. Instead of requiring custom-built structures, these gas appliances use special double-wall pipe and can be vented horizontally through a wall or vertically through a roof. This allows them to be very flexible in terms of placement and much easier to install than traditional wood fireplaces. You'll also find that most direct vent fireplaces feature a high efficiency rating, thanks to glass doors that radiate heat while preventing warm room air from being lost up the flue.
