Opened the door on my new insert last night, and discovered a coal must have jumped out on the the gasket and put a good burn in it. It is a bit frayed, but it is still sealing at this point. Is there anything I can do to repair a small tear in my gasket??? I dont mind buying a new one,,but the stove is only a few months old. Thanx in advance,,,this forum is fantastic. Happy Burning....Joey
