Morning I’m also looking for help and this is my first post so hope i’m in the place. I have a HARMAN Absolute -43 and each time the stove ignites I get a strong smoke smell in the room until the stove heats up! All pipe seems to be sealed well but I do see a very light bit of ash on the exhaust pipe where it exits the stove, pipe joint is sealed well so don’t feel its leaking there? Hoping some one has had the same issue and can help.
