    Customer Questions & Answers
    By Alex C. from Philadelphia on January 1, 2013
    Will this work with other brands or just with Napoleon? I want to install a Monessen fireplace, rear vent, which also uses a 4" x 7", but need a flexible vent pipe as I am not 100% sure of the exact length when ordering.
    By Tyler M. - Fireplace Specialist on January 2, 2013

    Answer:
    Indeed, this vent kit is only tested and listed for use with select Napoleon direct vent fireplaces. However, there is a flexible vent kit available for Monessen direct vent fireplaces with a 4" inner diameter and a 7" outer diameter: Monessen Up and Out Flex Vent Starter Kit. This kit has 40" of flex pipe, which can be cut down to the length you need.

    How does this work and does it prevent exhaust from coming back into the house via the air intake?
    By Will M. on September 27, 2016

    Answer:
    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.

    By Brian Taylor from Chetwyn, British Columbia on 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?
    By Collin C. - NFI Master Hearth Professional on September 21, 2012

    Answer:
    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.

    Does this Napoleon flexible rear vent kit include 20 inches or 20 feet of flexible vent pipe?
    By Tyler M. on May 4, 2015

    Answer:
    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.
