It hasn't been super cold but cold enough to make a fire. So I burn my little guy with about half a hopper full of pellets. I'm burning OHP brand from Orschelns. Normally I vacuum the ash each day but the one day I only scooped the ash and lit it before bed. Well evidently it smothered out or something because it has nonburned pellets piled up in the burn pot. So I guess my question is does this stove have to be vacuumed each day or is this brand of pellets high ash? I'm worried if I ever have to purn a whole hopper this winter it might burn out again. Appreciate any insight!
