Hello, Every one! I just bought a King Ashley 5500 from a friend. They didn't have a pipe kit for it, so I had to purchase one, which are about as elusive as wood pellets right now. I had ordered a Supervent and was given a Metalbestos instead, with no idea if the Supervent could be delivered. So, on to the beginning of the issues. The 3" pipe connenctor fits very loosely on the back of the stove. I stopped at several stores that carry the pipe and they suggested that I just use the high temperture caulk to fill the gap . Has anyone else had to use caulk around this pipe on their stove? What temperture does the pipe get to?
