    I want to add an intake hole at the bottom rear of my masonry fireplace in the fire chamber. Will this work to stop the unit from sucking intake air from the house?
    1 Answer
    Unfortunately, we do not carry fresh air kits that are made for masonry fireplaces. I apologize for any inconvenience.

    Can I vent a wood burning insert directly into a masonry chimney without additional stove pipe; and, is there a plate to seal it?
    1 Answer
    While some wood insert manufacturers will require a full reline via 6" or 8" UL1777-listed corrugated stainless insulated steel chimney liner, others will indeed allow one length of liner to run from the insert flue and into the existing chimney with a "block off" plate installed at the damper opening. I recommend reading the installation instructions for your insert to confirm this installation will be acceptable.

    I am looking for a replacement vent for a Direct VentHeat and Glow SL36. I believe the product number for the vent is DVK01. I am being told this is discontinued. Can I still get one or is there another one I can use that is comparable? Thank you.
    1 Answer
    Unfortunately, as we are not a Heat & Glo dealer, we do not have a suitable replacement for the vent. We apologize for any inconvenience.

    Do you sell any universal venting kits for wood burning fireplaces?
    1 Answer
    Unfortunately, manufactured wood burning fireplaces use venting that is manufacturer and model specific, so there are no universal options.

    I am installing an Astria Inglenook CLP2 wood burning fireplace. The unit calls for an AK4 outside combustion air kit. The AK4 kit on your website is listed as a "Majestic" AK4 Kit. I want to confirm that this AK4 kit is the same kit that I need for my Astria fireplace?
    1 Answer
    While the part number is the same, there is a slight difference between these kits. The kit you will need is the FMI Complete Outside Air Kit. The kit works with FMI, Vantage Hearth, Superior, and Astria units.

    September 17, 2014
    We recently purchased a home with a gas fireplace. The vent goes up a built out structure on the side of the house that served as a 'chimney' enclosing all three vent pipes. (It used to also have the vent from a gas hot water cylinder and a vent from the old furnace). Now the only vent pipe that remains is for this fireplace. I am wanting to remove this chimney build out and make the wall flat. I was wondering, can the vent for a gas burning fireplace be terminated on the other side of the wall or if it needs to go up and be vented past the roof line, as it currently is?
    1 Answer
    I can visualize and completely understand your installation. It is possible to remove the chimney chase and use a horizontal vent termination for the fireplace, if the fireplace is a direct vent type. If the unit is a B-vent type, it will require the vertical run.

    We just received our insert but forgot to order a venting kit for model # VT32NB-A. Which kit would you suggest for us to get? It's going straight out back and through wall. Can you please give us a link so we can view it on line?
    1 Answer
    We've got two kits that will work well for you (depending on the required horizontal run). If your wall is a bit thicker or if you're installing the fireplace out from the wall a bit, check out our Ground Floor KIt. If less pipe is needed, then our Horizontal Square Termination may be preferred.

    I am building a new house with a planned see through 36" natural gas fireplace. I'm searching for automated electronic controls for lighting gas logs, adjusting the height of the flame and opening and closing the flue. However, I am unable to find this information on your site. Can you help?
    1 Answer
    Because direct vent gas fireplaces are sealed from the room, the vent pipe will always remain open to the outdoors. However, there are selections to be made in regards to the electronic ignition and flame height adjustment. Are you interested in being able to perform these operations from a hand held remote or wall switch, or is manual control on the unit preferable? Please advise at your convenience.

    I need a direct temp vent kit for an Ashley MODEL # AP5660L pellet stove. I am going straight out, not up, and I need a kit and pipe. My home is 2x6 wall construction, please advise on parts to purchase. I was advised to use part Cpf-77406(kit) and part Cpf- 773 D.T.B (pipe). Is this accurate and is this all of the parts I will need to vent the pellet stove?
    1 Answer
    I believe we spoke on the phone a couple of weeks ago regarding your installation. For a direct vent pellet application, the parts you listed are exactly what would be needed for a horizontal application with no rise. As I mentioned on the phone, some of the components are unpainted in this kit, so they would need to be coated with high temperature black paint to match.

    Do you need to put a fresh air kit in a woodburning fireplace or can you build the fireplace without it?
    1 Answer
    Unless you live in a mobile or modular home, a fresh air kit is usually not required with a manufactured woodburning fireplace. For more information, please check with the manufacturer.

    I really need your help. We purchased this (Vantage Hearth Value Line Series 36 Inch Circulating Wood Burning Fireplace with Stamped Louvers) and thought that it came with a fan. For this fireplace, what can we use for the fan?
    1 Answer
    The proper fan for this particular unit is this item: Wood-Burning Fireplace Fan The fan will need to be positioned in the bottom of the fireplace, at the very back of the void space under the firebox floor. There is a removable panel beneath the bottom refractory liner that will allow access to the blower compartment. Please let me know if I can assist you further.

    I want to install an inbuilt slow combustion wood heater in my existing open fireplace. It has an internal wall with chimneys both sides. I was looking to make a hole in the wall behind the heater and transfer some heat into the rear fireplace with fan assisted ducting. Do you have any products for this purpose? The wall thickness is approx. 12 inches.
    1 Answer
    While we have many controlled combustion inserts that can be installed into an existing masonry fireplace, none of these models offer the ability to divert manifold heat into another room. Currently, only free-standing manufactured units that are designed to be framed into an existing wall have this ability. It would be possible however, to modify the insert for these purposes. As long as the amount of room in your fireplace allows, you would be able to fabricate a small metal manifold that could mount to the back of the insert and siphon some airflow from the built in blower to another area. I highly recommend consulting a sheet metal fabricator for this purpose, as this would be a specialty item. You could then attach a flexible duct to the sheet metal manifold and direct the heat into the area behind the insert. Please let me know if you have any questions.
