The Ashley 22AF is an older model not produced since 2004 but, parts are still available from U.S.Stove http://www.usstove.com
. The grates are the same as the 1537-1557 Hotblast's from USSC and from the posts of other owners of this style of grate, they are not the best made but, can be modified to perform well. It will probably do a satisfactory job but beware of it's limitations. The advertised output is 31,000 - 87,000 BTU's. If the price is right, I'd grab it and use it in a garage or small house. You'll be able to burn bituminous coal and wood in the unit and anthracite with a little more patience. This stove would be a good starter if you don't have to pay too much for it. Don't forget to install a barometric draft regulator into the stovepipe between the furnace and the chimney. You'll be able to control the draft through the stove for a more consistent long burning fire.
