I had replaced my original gasket with a silicone rope gasket a few years ago. I noticed at the end of last year that, despite turning the door pegs all the way little by little over time in order to get a good seal, there was still some smoke escaping from around the gasket after three years of use. I ordered a new gasket, but before installing it, I had the idea to take the old gasket out a just turn it upside down so that the "clean" side that wasn't in contact with the boiler was now facing out. I readjusted the door pegs, and so far so good...a clean seal. Hopefully it holds up over the winter. I can keep the new gasket for future use. Anyone else ever have success doing this?
