I've burnt "clean burn" in my Breckwell 24I for about ten years that I'd get at my local Scott McClendon Hardware with no problems. Now they're nothing but a real PITA. Fire goes out, pellets won't feed, and auger jams. I now burning "Blazer Premium I get from Lowes with no problems what so ever (I've made NO other changes). Anyone have any idea what the big difference might be? The stove is 14 years old and has been serviced each fall before burning season starts.
