I recently acquired a 25 pdvc that I am using in an uninsulated garage near the shores of Lake Erie. I am seeking advice on how to keep a consistent burn. The stove starts up nice, then flames up real well for about 5 minutes or so then burns down to just coals for about another minute to 3 before it flames up again. This is making it hard to warm the place up because the air around gets cooler before the next time it ignites. The bottom 3 settings are 6-4-1, and no matter what combination of heat and blower speed I set, I can't get the thing to just have a nice constant fire. Is this how the stoves work? Is it possible to obtain solid flame? Thanks for the help.
