Hello all, I cleaned my stove and chimney this weekend getting ready for the season. Upon removal of the cat for cleaning, the gasket disintegrated. From what I'm reading this is normal. I found some at Condar's website, but the shipping costs more than the gaskets. I figured I'd get some extra to have for the future. 4 gaskets were over $13 to ship, at 4 pounds. How the heck do 4 gaskets weight 4 pounds? Is there another source for these or am I just being cheap? The closest dealer is 60 miles away.
