Richard, thanks for the reply. With your input the manual is making more sense. I think it is best that I stick to the coal the stove was designed for while I am getting to know my them. Finding a truck load of the stuff has been a trip. The sources listed in the yellow pages under 'coal' do not answer their phones, most do not have answering machines, the ones with answering machines do not return calls and when you do get someone they make it all very hard or no longer do coal. I think I have found a source in a guy with a truck across the street from a coal yard, but the only size coal he delivers is a mix of pea through nut. I think this mix is smaller sized then the manual recommends. I am just happy to have found a source, but am I just getting myself in trouble getting the smaller sized mix?
