:coolhmm:
Double wall not class A. Class A is from your support collar up.
Flue temps are already low leaving the BK. 250F and lower after the stove settles out on turn down. They just want to maintain some stack temp for condensing possibilities. I will get Ice build up at the top of my stack in winter as it runs that cool. The water vapor will ice up at the cap. This is with wood that has an average of 15% MC.
Hope Ive helped and not confused.

Thanks, N. We don't lose a lot of sleep over ice here in NC. As far as draft, like I said,
my Dutchwest drafts fine, but I suppose the flue gasses on the BK might be siginificantly
cooler, but it seems unlikely to me.
So there is a kind of "double wall" that's less insulated than the 8" OD stuff that my
chimney is made from, and that's what they want you to use between collar and stove ?
One more question, how clean does the door glass stay ?
