Still running the stove to take the chill off at night. Ran out of pellets and the only ones i could find were Inferno's from Lowes. Bought two bags, burned less than half of one and the stove and doors were covered in black. The rest of the bag got vacuumed out and the other bag is going back Monday. Luckily i found some Athens pellets today to get me through. Six bags should take me through the Maine summer. Fall starts in two weeks.
