I'm not so sure you're viewing it right , Dr Crane. The intake port is
in the back bottom of the stove, but is open to the entire grate area. It isn't particularly "shooting" up the flu. No different than a stove that has a couple screw holes in the frt. Both are exposing air "under" the grate system. When my grates "aren't" clogged, the entire bed of coals burns healthy, across the whole grateing area, not just the middle.
Have a safe trip and Happy Birthday!!
Thanx Lee. 1 more day tho, the 31st. (I was a tax write-off for my father

Good luck with it. "Hopefully" we'll get it.
Update on this morning. went to bed at 11:30, and awoke at 5:30am (for the same reason), and the fire was still blazing. "But" the heat exchanger temp had dropped to 200* meaning the grates were clogged. The draft was still healthy @-.05. I "didn't" do anything to the grates. Wanted to see how much longer it would burn. Went back to bed, and returned at 8am, to a dead coal bed. And Lee, my draft was still -.04. I did disconnect the manometer to see if it was reading correctly, and it returned to 0, so it was still hot and flowing. So, as we all know, it is the restriction of the air to the coals, that's choking it, and not the flow of exhaust killing it. Once I get home tonite, I will try and insulate around the liners, and see if that helps. Have a "relaxing" day, Gents.
