I guess you're not a PETA member, then? You seem to have a large circle of friends that burn wood. When you say that BK owners you talked to have "stalled" their stoves and had creo smell, does this happen when they run their stoves on a low cat burn with no flame in the box, or when they actually stall the cat and the probe falls out of the active zone? What are the "worse stories" you have heard from people that have other brands of cat stoves? From what I've read here, the BKs are the only cat stoves that are very picky about draft...mostly the Ashford. Yeah, you are going to lay out more money any way you go, new chimney or new stove. If you can use your Class A from outside, you only have to pay for the install, which shouldn't be too bad. Maybe less than the 2.5K+ you'd pay for a good quality stove, minus what you could get for the BK. I think a better chimney (inside the house with less turns) would probably get rid of the smoke to a large degree, and getting your draft measurements might support this theory. You may still have a little odor with the Ashford but people seem to put up with it. BTW, no 45 elbows once you get above the ceiling support box into the Class A.
