We have a recently installed Jotul 3CB. The folks who put it in were not the greatest and to get the double walled (Selkirk) pipe to fit to the box pass through the roof, they ended up installing the pipe upside down. We expected some smells when we "broke" in the stove, but it still smells some and makes us wonder if it might be the fault of the pipe being installed the wrong way. any advice would be very welcome. thank you!
