Ok I have a new gasket, a new combusiton blower, and. im still getting a slow backup in my burn pot. Ive cleaned the hell out of it. Ive had it for 2 years and it has the baffle plates, it seems like the baffle plates block any ash from going behind ihe inside wall so.I have never had ti clean the trap doors on the wall. Should I remove the baffle plates for better air flow?
