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.

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.

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?

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.
