Of course its 21 degrees here and I never replaced the gasket.  Just how long does the stove have to sit idle before firing it up.  The package says 12-24 hours and it is rutledge if I remember right.  Its a hampton HI300 so it has a groove to hold it in place...  Its about 4 or 5 years old.  Thats about the life span I got out of the gasket on my old insert....sound about right to you guys?
