I must have missed this thread before
....I have to do the same thing with my old circulator stove, there's no secondary (above coal bed) air control but it's not that big a deal because even though the loading door is barely ajar to burn volatiles better it is still latched so it can't come open on it's own. I use a Baro damper as well and it helps keep hot air in the firebox longer helping to burn off volatiles. Another thing I do is burn a roaring (but not overfiring) wood fire (baro capped) with good hard wood so there's no creosote and it blasts the soot out pretty good. I get flakes of soot all over on the snow afterward but they don't hurt anything. I only brush out the chimney once per season and it doesn't really even need it then.

Can you just modify the one you have? Does it have the spark arrestor screen or just holes?
