    from Lake Villa, IL asked:

    Since there's no damper or shut off valve is there anything or anyway to keep the outside unconditioned air from coming into the fireplace/house when there is no fire?
    1 Answer
    If this kit is installed with certain Superior fireplaces that have functional outside air control, then you would be able to fully close the outside air. With other barometric models, the outside air connection is covered with a flap that would only open to allow air into the combustion chamber if needed. In either case, no air would be allowed to enter the combustion chamber.

    What does this provide air to and what is its advantage or necessity? 
    1 Answer
    An outside air kit would only have to be purchased when required by local codes. The benefit of installing outside air is to draw fresh air from the outdoors instead of relying entirely on oxygen from the living space for combustion.

    from Indianapolis, ID asked:
    December 21, 2014
    Does the outside air intake use the same void around the firebox that the blower uses?
    1 Answer
    It does not. There is an steel tube that travels between the inner and outer chassis of the fireplace which funnels air to the firebox directly and prevents any mixing of outside air with indoor air.

    from New York City asked:
    November 24, 2013
    If the exterior wall is 5 feet from the fireplace can I still install the air kit?
    1 Answer
    Yes, however the outside air kit ducting would have to be extended for your purposes, as the standard duct length would not be sufficient. Aluminum dryer ducting is able to be used to extend the air kit if needed.

    from Minneapolis asked:
    January 13, 2013
    Can this unit be installed outside?
    1 Answer
    This item is designed to draw outside air in through an exterior wall and supply it to your appliance. The flex venting will pass through the wall to the appliance. Only the termination would be located outside.
