Great site, glad I found it. New to a Vermont Castings Catalytic wood stove. I've noticed that there are gaps (light shines through) between the collar and the oval to round transition. I would like recommendatons on high temp seal. Also interested in the how to apply.. Come in from the top, remove collar or attack from bottom? Any help/advice greatly appreciated.
