Bought 10 bags in the fall to try them and they seemed to burn nicely in my Quadrafire Castile. Went and got 2 tons delivered and am getting huge clinkers that look like chunks of lava and a lot of heavy ash in the burn pot. I have to empty the burn pot 3 times a day to keep it burning properly. Other than the clinkers and the ash build up they burn hot with a vigorous bright flame. Is there anything I can do to help cut down on the clinkers? Last year I used EasyBlaze premium and they burned very well with hardly any ash buildup in the burn pot. The dealer I got them from was having a hard time getting the EasyBlaze this winter so I switched to Energex.
