I just replaced the door gasket on my Clydesdale after the old one started falling out. Used Rutland 1/2 inch gasket. The old gasket didn't pass the dollar bill test and the new one doesn't either. Should I try it on a warm stove or do I need to regasket the old horse? Thoughts on firing it up and seeing how it goes? I didn't stretch the gasket out very much on the instal, so I'm a bit disappointed.
