Hey everyone, I'm into season 5 with my Chinook 30.1 and have had great results with the stove so far. While giving the stove a good clean out before starting to burn this year I noticed that the cat was slightly out of it's gasket. I was able to push it back into place with no problem and I haven't noticed any negative effects from it.
It doesn't seem right to me that the Cat is that loose in it's gasket. Am I better off pulling it out and replacing the gasket or is this normal?
They can walk out a bit. If you can push it back in and it stays there I would call that a completed repair.
