    Hi all,
    Apologize in advance as these are probably some amateur questions.

    Picking up a Harman P43 tomorrow to replace my existing Quad Contour. Trying to understand what I need to do to install and if I can use the existing pipe that was in place from the Contour? I will need to add the OAK piping but the current exhaust pipe sits about 6" higher than the exhaust port for the P43 (assuming direct out the wall).

    What are my best options here and am I in DIY territory? Its a used stove so no dealer helping with install. The stove does come with all piping the old owner used - just trying to avoid new holes in the house.

    Thanks

    Because the outlet is higher you can lower the hearth or
    put a new hole in the wall . Exhaust must go up never down
    this allows for natural draft

    Hi Marilyn
    Welcome to the forum. :)

    An EASIER way is to put 2 - 90 Deg pellet vent Pipes together and connect one end to your existing vent pipes, then rotate until the other end is at the proper stove height!! LOL Easy Peasy!

    What will you do with the old Quad Contour?
    I have a Contour myself.
    :)

    See pic example below of a Harman P68 that replaced a Harman Invincible RS which has a lower exhaust flange.

    Although @Don2222 's method will work (and that is what I did for my P43), it is really pretty easy to raise the stove by 6" using landscape blocks on top of the hearth pad. Bonus is that that the stove is higher so getting back behind to clean out the fines box, or work on motors is much easier.

    BTW - my P43 is on 2" blocks and has a couple of elbows for the exhaust to match the height because the first stove installed there had aboth a higher exhaust outlet and had about 1.5' of vertical run.
