I have a M55-FS installed and burning for 2 months and a couple questions for fellow owners. Do you burn on the setting for Regular pellets or Premium? I burned Dragons and Barefoots on both settings and at all feed and air trim settings (learning curve/tinkering). When burning Dragons on all settings the agitator pushes ash off the burn pot, however on Barefoots set at Regular pellets, heat level 3,feed rate 1, air trim 5 the agitator pushes red coals/ pellets off the pot, I can see them glowing in the ash pan, exhaust gas/smoke visible none. On Premium setting, same settings, the agitator pushes black/grey ash of the burn pot, exhaust smoke is visible. On premium the pot naturally fills up more between agitator times and seem to smolder a bit more (ie. the visible smoke). How does this compare with you? Agitator noise is agitating No control over convection air annoying. Dragons hot & clean. Barefoots HOT & little more ash.....real HOT!
