I picked up one of these used. It's definately hard to start on corn. It's basically a manual stove it you want to burn corn. The settings that the chart on the side reccomended for burning corn aren't really that good. It keeps going out on those settings. It seemed to burn better when set for cherry pits. The dealer I talked to said this was more of a corn stove then pellet, but I don't see that. Maybe I need better educated on the settings or something. The manual is pretty useless.
Great with pellets. I really like the burn pot. It's about the best design I have seen yet. I burned about 60 lbs of pellets and there was hardly any ash. The corn clinker falls right out without any effort. It has a big ash pan. Overall I like it. I don't know what CFM the heat exchanger fan is but I think it could be more. Wish it did better with corn. The sales pamphlet touts the stove as being designed to burn high ash content fuels so I am eager to get some worthless pellets and try them out. I'd really like to get my hands on some grass or leaf pellets that had been made with one of those small home pellet makers and see how they burn. It would be great if I could make my own pellets from my mowing clippings and leaves.
