That will burn up the coals but I may have to do it several times. I figured after 10-12 hrs that would be burned up on its own. It’s kind of a pain to have to take coals several times a day and just put one piece in at a timeSo 200-300ºF. That's important. 200F is low, 300F at 10-12 hrs is not bad. Try tossing in a couple 2x4 cutoffs on your next coal bed with 50% air at the 10hr point to get the stovetop up to 400+º F. Or if you have some good dry pine or fir splits that are about 3" thick that's fine too.
