    How do I attach the inner portion to the fireplace (the 4" one)? Is sealant just enough? Also, what kind of fire stop would I use with this kit?
    1 Answers
    Typically, Napoleon fireplaces will require the inner flex section to be connected to the flue collar with Mill- Pac, but the specifics for venting the system should be included in the product literature for your Napoleon fireplace. If you do not have a Napoleon direct vent system, please note that this liner kit would not be appropriate. With that being said, the Napoleon Direct Vent Firestop - For Use with 4 Inch x 7 Inch Venting Systems is the appropriate firestop for this kit.

    How does this work and does it prevent exhaust from coming back into the house via the air intake?
    1 Answers
    This venting kit is only approved for use with Napoleon direct vent systems that use 4" x 7" coaxial venting. With direct vent fireplaces, the inner pipe of the coaxial system is responsible for exhausting flue gases and the outer pipe is responsible for pulling in combustion air. When installed correctly, this provides a balanced flue system with direct vent hearth systems as the combustion chamber is sealed from the home via a solid pane of tempered or ceramic glass.

    Does this Napoleon flexible rear vent kit include 20 inches or 20 feet of flexible vent pipe?
    1 Answers
    Yes, this Napoleon vent kit includes 20" (inches) of flexible direct vent gas pipe with a 4" inside diameter and a 7" outside diameter. Please note, however, this vent kit is only tested and listed for use with select direct vent fireplaces manufactured by Napoleon.

    from Chetwyn, British Columbia asked:
    September 21, 2012
    I have a CFM Insta-Flame natural gas fireplace that is direct vented to the outside wall with a wall termination cap that is now covered by a roof. It is direct vent, and I would like to split the intake and exhaust so that it can take the intake air from under the roof and exhaust through a flexible pipe to the roof end which is about eight feet away from the wall. Is it possible to use the napoleon flexible pipe too achieve this? If so, what will I need to achieve this?
    1 Answers
    Unfortunately, components are not currently manufactured that would allow you to perform this type of conversion. Because the vent piping is coaxial and the exhaust vent is the inner tube, it would not be feasible. My best suggestion would be to remove the current wall termination and extend the vent pipe slightly, then use a 90 degree elbow to vent vertically through the newly installed roof. This would really be the only option, short of moving the stove completely.
