I've been posting here because my Super 27 hasn't been giving off much heat and not much flame on the wood. I knew the wood was dry so I couldn't figure it out. Tonight the smoke backed up into the room and filled the house with smoke. I've read it's likely creosote build up but I'm surprised at this because we haven't used it very much. This is the first year we are using it every day. So I guess a chimney cleaner can fix this problem? It shouldn't be anything wrong with the stove itself?
