    Direct Vent Fireplaces

    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.

    Do I have to buy a barrier screen?
    1 Answer
    Commencing on January 1, 2015, new legislation went into effect that requires all glass fronted hearth appliances that exceed a 172 degree glass surface temperature to have a safety barrier screen as a standard feature. Many manufacturers redesigned their appliances ahead of this date to include a barrier screen as standard, while others made the screen a required add on. To stay in compliance while still giving our customers a choice, we do not require the purchase of a separate barrier screen in cases where the manufacturer does not make it a standard feature. However, the screen will always be presented as a purchase option and is highly recommended. An example of a unit with the screen listed as a configuration option is the Empire Tahoe Deluxe. As you will see, the screen is listed under the first configuration step for this unit. It is important to note that almost all hearth appliances allow removal of the screen after purchase, if the customer so desires.

    We have a new Cape (single story, unfinished walk up attic, with a 10/12 roof pitch). We would like to install a see through gas fireplace on the first floor that would have a floor to ceiling wall and we would be able to walk around either end of the fireplace (it will not be attached to an outside wall). I like the idea of a direct vent fireplace, but have a few questions. 1) What is the size of the vent required? 2) Does the vent need to run vertical, or can it have bends in it? 3) Can it be vented through an eave soffit or does it need to be vented through the roof? 4) If vented through the roof, what height does the top of the vent need to be? 5) Can installation be completed by a DIY-er, or should it be left to a professional?
    1 Answer
    1-Most units take either a 4"/7" or a 5"/8" vent pipe. 2-It can have bends in it to avoid rafters, studs and to get to an ideal locate for roof penetration as well. The amount of horizontal run does depend greatly on the unit and the amount of vertical it is run as well. 3- It can vent either way or vent on the horizontal on the side wall of the home. I can help you design the best venting option for the unit and your needs for you. 4- This varies on the unit as well. In general it can be between 12" and 24" 5- That really depends on the Home Owners skill set. A lot of the framing and finishing of the unit can be done by a DIYer with good wood working and hand tool skills. The gas connect though should be handled by a profession gas tech or plumber (again depending on the DIYers skill set)

    can you use fire glass in a direct vent fireplace?
    1 Answer
    Direct Vent units have specific media rated for their use, so you will have to find a model that offers glass media for its burner.

    What would make my vented gas fireplace smoke up my siding?
    1 Answer
    Having a dirty flame could cause sooting to appear on your siding. This would be the case if your burner flame currently has any black tipping and would be rectified with a proper cleaning, which typically involves removing the front glass and any logs and media to vacuum the burner pan. Of course, this may also be the result of a vinyl siding shield not being used. If this is the case, the vinyl siding will be damaged from excessive heat.

    The attached photo contain the measurements of my current wood fireplace. I would like to install a gas insert. What size do I need to purchase?
    1 Answer
    Were you looking for a direct vent insert or something vent free? Also, did you want to operate the system with a remote? Also, would you like a system featuring a standing or non-standing pilot flame (electronic ignition)? If you would like a remote, would you also like to be able to control the burner flame height? Are you using natural gas or liquid propane? To include the venting, we will need to know the total height of the chimney, measured from the hearth floor (this would only apply to direct vent inserts). Please view our selection of gas inserts here and please re-attach your hearth measurements when replying to this email. If you need further assistance with this, you may reach me (Will M.) directly at 1-800-203-1642 ext. 404.

    I'm looking for a low-priced, propane, approximately 36 inches wide, fireplace with a blower. Do you have any recommendations?
    1 Answer
    I would first suggest the Empire Tahoe Deluxe Direct Vent Propane Fireplace - 36", as it is within the builder line of products by Empire. This unit does allow for a heat circulating blower to be installed as an accessory, seen here. Additionally, Superior offers their line of Merit Series fireplaces, such as the DRT2035, which also has a blower accessory available for it.

    I am in the process of designing a 3 condo complex and am interested in featuring gas fireplaces. The one exterior wall on which I would place them is at the front of the house. I am curious what is the lowest possible exterior profile, in other words, I don't wish to see too much piping at front of house. How small can we go?
    1 Answer
    Many of the direct vent fireplaces by Empire can utilize the Duravent Direct Vent Pro venting, which offers a horizontal round termination cap measuring 11" x 11" seen here. Once installed, this would be the only component of the venting system exposed to the exterior.

    I am looking to install a natural gas fireplace in my basement. I would need to vent it up to the ceiling (about 5 ft) then horizontally through the joist cavity (about 6 ft). That cavity would be covered with drywall for the last 4 ft. First, is this even possible in a direct vent application, and if so which brand fireplaces would better for this sort of application?
    1 Answer
    Creating an enclosure with drywall in the fashion you describe would simply reduce your clearances with a situation that is already not ideal for terminating a direct vent fireplace as drywall is considered combustible. Typically, direct venting will have anywhere from a 6 5/8"-8" outer wall with 1" of clearance to the bottom and sides and 3" of clearance at the top, meaning that you would have up to 12 5/8" of height that would need to be maintained to ensure clearances for the horizontal run between the floor joists. Additionally, horizontal runs of direct vent pipe will typically require 1/4" of rise per horizontal foot, meaning that you will need an additional 1.5" of vertical clearance with the horizontal run, so choosing a fireplace that uses 8" outer diameter venting will be out of the question as floor joists are typically 12" and your horizontal run would require 14 1/8" of clearance. Even with the smaller 6 5/8" outer diameter venting, this would require 12 1/8" of clearance height, so the termination you describe will not be possible, unless the floor joists are taller or the horizontal run to the outdoors will be between the first floor and a crawlspace with a cement floor.

    I have a gas ventless gas fireplace and I'm not happy with it. I like the direct vent fireplace but my house is all brick and I was told that I couldn't install a direct vent system through brick. Is this true?
    1 Answer
    You may absolutely install direct venting through brick. Someone may have been mistaken and confused the requirement for the exhaust vent for a direct vent insert (for existing wood burning fireplaces) to terminate at the top of a masonry chimney, but direct vent fireplaces (that you frame in) allow many configurations for venting.

    We have a Superior direct vent gas fireplace. The vent outside has a tilted vent cover that allows birds to make nests between the cover and the box as well as the pipe that connects to the box. Is there other vent boxes that would prevent this birds from getting into the box?
    1 Answer
    We would need to know the model number of the fireplace in order to see if alternate caps are available, but I would recommend securing installing screen mesh to prevent this from happening. This material can be sourced at a local hardware store. This product may also work, so long as the dimensions of your cap are suitable.

    from Holyoke, MA asked:

    We have a direct vent gas fireplace where the vent protrudes from an outside "dog-house". When the fireplace is not being used, cold air comes in all around it. Why is this happening?
    1 Answer
    It is highly likely that the fireplace "dog house" was not air tight when the fireplace was installed. It may be necessary to remove the siding and seal any cracks that may be allowing cold air to infiltrate the home with fireblocking adhesive and foil tape. With modern construction, the rest of the home is likely to be tightly wrapped and the same guidelines would have needed to be followed when the fireplace was installed. Homes are pressurized and there is a constant exchange of air taking place. If the remainder of the home is tightly sealed while the "dog house" is not, air will be pulled into the home from any gaps in the construction in this area.

    What is a recommended minimum BTU output for a room that measures approximately 22x24 with the allowance for a stairwell? The room is the lower level of a split foyer home with the front being half below ground and the rear at walk out level, all with a standard 8 foot tall ceiling in place. Will the recommended BTU output be the same with or without a fan?
    1 Answer
    A minimum BTU rating for your space would be in the 17,000 BTU range. The addition of a blower would not affect this rating.

    Can I do a basement install with a direct vent LP gas log fireplace?
    1 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.
