    This is my first install on a wood stove, and need some advice for pipe/parts needed.
    It is an older Comforter stove wiith an oval hole in the back (measures roughly 8.25" x 7").
    Here are some pictures below.
    I'm installing myself. The roof is an 8/12 pitch. I'm looking for a list of materials/pipe/pieces I need to properly install the stove. Prefer to go with double walled as it's inside a dwelling.
    I'm new to wood stove installation, so a quick list of guidelines would be really helpful.
    Much thanks for your help in advance.

    The most important thing here will be to honor the required clearances to combustibles of 36" in all directions unless there is an NFPA shield. It sounds like the stove will require an 8" round pipe. Is that what you have flashed for?

    Don't know if it matters to you, but in Oregon it is unlawful to install/operate that old wood stove. Your homeowner's insurance carrier may not look too kindly on it, either.

    It is flashed for 6" pipe. I plan on putting a shield/barrier behind the stove an inch or 2 from the wall.
    As I understand it, there are tapered oval to round connectors that I can get to go to 6" pipe. True?
    I went to the local wood stove shop and they gave me the following list of pieces I'll need to make it work.
    Would appreciate any extra input. Want to have this installed as safely as possible (within my budget). Thanks!

    Oval to round adapter
    6" T
    4 3ft sections of double walled pipe (possibly 1 telescoping)
    Ceiling support box
    Class A pipe in 4ft sections
    Cap
    Storm Collar
    Roof Support Brace

    Now where should I be looking to get the best deals? Someone suggested I look out of town, in the Columbia Gorge, that it is cheaper out there.

    It is not advised to downsize stove pipe. This may work for you. If not you may notice smoke spillage when loading the stove. Even with a properly sized and installed wall shield, the closest the stove can be to the wall is 12".

    Comforter used a 7" pipe - the crimped end of 24ga fits inside the oval on the rear of the stove.

    That said, a tall 6" should probably work very well - as I remember, it may have been allowed to use 6" when used in a certain way (coal, because the front door stayed closed and it was loaded through the top).

    With that kind of a height, it should draft to beat the band.

    7" double wall is also available. It costs less than 8".
