Any chance you think some of the issue could be the ratio of the system heat riser vs horizontal burn tunnel and feed? In the pic they look pretty close 1:1 vs the 2+:1 recommended in the book and on this forum.

Actually, what I meant to say above was that I thought I had discovered the opposite, that the burn tunnel CSA was a lot larger than the 6 inch pipe CSA. I really DID need a break!
