Hi all, I have a few questions. Pictured below is my setup. Do the joints of this pipe require some type of buttle tape/sealant or just held together with the bracket and screwing together? The bends dont seem to be a tight fit. The pipe simply slides into the stove top with nothing keeping it there other than its own weight. I am able to get fires to burn good and hot but no matter what when I open the door smoke will fill the room. Even with cracking the door for a while and the fire being hot. No difference weather a window is open. Pipe is clean and the chimney extends 4 feet above roof line. No trees near by. Thirdly, I was thinking about swapping this stove for another that my parents have.(Nicer, Newer) Do they make an adapter that i could go from the double wall to single wall down to the new stove? Would make it easier to attach and cheaper. I did read some of the faq's.
