Third season on pellet stove.Basket is full of unburnt pellets and ash catcher has pellets and hot embers.Toatly disassembled and cleaned it all. Chinmly is drafting efficiency. Useing pro pellets that have been very good to me over the past.its a vogelzsng by 5790 running it on setting one it uses1.8 bags a day very consistent from year to year. After I cleaned it same result. Have air inlet open so that pellets are at the smallest flame possible at slowest part of the cycle.Could I have a bad pallet of pellets? I'm at a loss been fighting it for weeks.
