For starters- -5f with -30f+ windchill tonight. The front room is 65.3f which is too cold for me. The Timberline would have had this room 10 deg. warmer last year. The BKK is 500f stove top, and the CAT is 1600,-fan is maxed. and flue is at 610f. 'Stat is at 3+. What am I doing wrong? If I lower the fan I'll max out the cat., but the stove top doesn't get up tp temp.(600f. +) I have never had the stove above 630f., without maxing out the CAT. I have checked the door gasket, tough to pull a dollar through at the top/ latch side( pretty tight all other areas.) The by-pass clamped the dollar(s), and let me rip them apart. It's tight enough. What am I overlooking? or do I need to start shopping for a more radiant stove with an 8 exhaust.? BTW- Happy New Year to everyone!!
