2nd year with GCi60. Last year the pellet burning was fine and I only needed to clean it once a week like clockwork. That was on a fan setting bewteen 4 and 5. This year anytime I run the fan above 4 the pellets appear to drop too fast and pile up into the chute. What is causing this? How can I fix this? I have the stove on the premium pellet setting and use a Lignetics premium pellet. This stove doesn't really let me do anything except adjust the quality of the pellet and fan speed that I am aware of. The trim buttons appear to be useless. Also, the soot on the glass is much thicker than usual. I often feel like I have to educate my installer because he doesn't have enough experience with this stove. Help? Suggestions?
