Coals keep going out on me. Manual says to keep air intake slot door open. This is above the coals. Might this be my problem? Furnace burns wood beautifully, has no barometric damper but great draft, 8" pipe, damper control on flue pipe, and damper door to ash tray. Burn strictly anthracite. Any tips are appreciated. Thanks.

Most likely, anthracite wants all the air from below. Get it going good and fill it up all the way. It likes it deep.cheechblu wrote:Manual says to keep air intake slot door open. This is above the coals. Might this be my problem?
Wood and bit coal wants air across the top. Anthracite coal wants it ALL from the bottom up. Air going across the top of anthracite doesn't help except when you initially load it up. The xtra air across the top helps to burn off the gases being generated. Once they are burned close the top air and go only with bottom up air.
