I would be super concerned with the fit of the ash pan door. If necessary put a sheet of wax paper across the opening and then put a bead of high temp silicon on the mating surfaces of the door. Close door against the wax paper until the silicon cures. Should insure an airtight fit. The air intake slide also should be tight.
I already anticipated using stove coal in this stove and I bought 540lbs of it to start. I inspected the grate even harder and I found 2 little fractures in the grate, so I don't want to damage it any further if I need to make a casting. No one sells anything for this stove and has zero information on it. As far as I can tell it's the only model stove of its kind from that manufacture, left. The wax paper and silicone is a good idea, the ashpan cover fits really well as is though but I'm going to do the silicone to make sure. I bought the new grate for my WM and its not moving for the winter so this one gets all the attention. I put a lot of effort into restoring this cannon heater and I don't want stop at the grate
. Each section was sealed with cording and cord gasket was added to the door as well. This is the most air tight it's ever been I'm sure.
