I'm not understanding. How can you have a gravity fed hopper, and the bottom of it "not" touch the burning coal bed? Does anyone have a picture of this? This is what my old Surdiac looked like in operation.
you can run it as a hand fed without the hopper, or put the hopper in there and fill the hopper by hand. there are a couple steps for hopper height that raises or lowers the bottom of hopper position, I am guessing the higher the bottom of the hopper, the more coal spills out and thus a bigger fire, and vice versa. But as with any stove , do not "overfire it" or the overfired parts will disappear, in time.
