Convert 3 to 4 inch vent for liner through chimney Harman p68

[Thewajd]

Just a quick question that I probably know the answer to but want verification. I’m moving my stove from a through wall set up to a fireplace chimney. I’m going to do 4 inch SS insulated liner through brick and clay flue. My question is what’s an appropriate adapting pieces to conver the 3 to 4 inch vent?

Edit : I figured out the solution with more research, guess it took asking the question out loud to get the answer

Did you pick a 3 to 4 adapter? That is what my guy did on my P43 basement stove. Then the rest is all 4 inch after that. He put
it right at the stove attached to a stove vent adapter that they make for my Harman. You can't really see it as it's behind down low.

The kit I bought had a clean out T that went from 3 to 4. Hopefully it works as intended and it has good reviews

Actually, that may be what I have too. I do know there is a tee there. I will check when I do my cleaning which is coming up.

Edit - checked - He used an adapter. It is 3 to 4 and about 4 inches long. After that is a 4" cleanout tee.
