Got a Appalachian insert Cat. SS liner in a masonry chimney inside the house. I just reloaded and now have smoke coming out the blower. Like pouring out the blower when it is on. Any ideas? I have been having to clean the Cat 2x a month this season as it is getting clogged w ash. But when that happens the fire smolders. Now I have a hot fire that burns fine when all shut down, but something is not right
