Hello - I have a 10-CPM stove that is now burning Stove Chow pellets (used Maine Wood pellets last year). These pellets are not burning efficiently and are starting to quickly accumulate to the top of the burn pot (fan speed 5/5 and above), is there anything I can do to make them burn faster? Last week I used a remaining bag of Maine Wood pellets and experienced no problems even with fan speed of 7/8. My current stove setting is 1-4-1. Any help would be appreciated. Thanks!
