So I finally installed my Afton Bay. The question I have is I used a silicone called smoke buster or flame buster to seal my venting. I guess this silicone is approved up to 300-350F. The tube says high temperature Silicone but that doesn't seem high enough for me. Should I remove the Silicone and get something different. I did burn in the stove tonight for 3 hours but turned it off overnight because I am uncertain of the silicone temp rating. Also this stove is vented different then I had it before. Now it runs into a T and up 3 feet into a 90 and out the chimney which is 20-25 feet high. Will I need to mess with my draft trim?
