I tried my high temp at startup to clean up the firebox, saw 650 temp above the cat on the ir temp gun and got that new stove smell again (pancakes) so I wussed out and backed it down. This was about 10 min past closing the bypass so what's safe max stove temp above the cat?
Yes, what he said! I should read the owner's manual again, but I don't remember seeing a top end temp mentioned.
