After a week now with my new (used) stove, I'm finding that I get considerably less burn time from a bag of pellets than numbers I've read about this stove. I'm getting around 18-20 hours per bag on Heat Output 1 compared to 35 to 46 hours claimed. Is my consumption typical for this stove? I think I have the damper adjusted properly. The stove has no trouble burning continuously on 1; no burn out or build up with premium pellets. I suspect that the previous owner may have increased the auger feed trim. All three trim pots are set the same and not at full left rotation. I'm guessing they're either all still set to the factory default settings or the previous own cranked them all up, not knowing what he was doing. Does anybody know which of the three trim pots is the auger trim on the older, silver faced control boards? The manual only shows the newer control board with the trim pots labeled. Thanks!
