I agree with the draft and wood too wet as the culprit. For a 6" to draft well for an Encore is asking a lot. I had one on a 23' (above stove top) and I could not get it to draft that well with that big a stove. Downdraft stoves are draft needy. Also if he's getting centers >20% that's still too wet. He also has two 90's on that pipe which doesn't help with draft. Just my thoughts though.
