sounds like liner accumulation from a season or two unloaded down the pipe and plugged it off......that, or the homeowner lets the ash bin overflow and lets free ash go everywhere....but hell, its not the owners' fault...never is.....its the damn stove, the moronic techie, or the evil satan stove dealer who never told them they had to clean it........"owners' manual?!.....pfft, I never read those things..."
