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

what about a T off the stove, angled to a short straight pipe (6") then to a 90 deg elbow through the thimble? Else raise the hearth to run a straight horizontal out.

Thanks for the reply. Will have to see about your first suggestion. I think raising the hearth is out of the question as I think 6" is probably a bit much and would look weird.

They make a adjustable 90. U should be able to twist enough to line up.

I have a similar issue with my new P61a that is in route. I showed the dealer pics and measurements and his plan is to put a T out the back with a 90 to get out my existing hole.

So that will make u at least 8 inches away from wall.
If it were me I would just build a nice platform and finish it out in a nice tile or even drywall to blend in with the wall. But that's just me

I think I may go the same route. T off the stove into a 90 and out. My other dilemma is the stove came with Harmans oak kit but Im not sure I want to mess around with swapping out wall thimbles. Might just use a generic oak that doesnt connect into the exhaust thimble.

The piping just gets a little more convoluted. I changed out brands of stoves (different exhaust heights) and from a corner install to a straight install. I couldn't move the pipe over because of obstructions in the wall, so had to use the same hole. The exhaust does angle upwards and that is a clean out T at the exhaust from the stove. Not pretty, but it has worked well since installation fall of 2015

Raised hearth. 6” is quite low. My freestanding stove is on a 10” tall hearth.

Yea i think i was misunderstanding raising it at first. Build a base for the hearth to sit on is definitely the way to go and should be real easy
