This is what happens when you burn crappy pellets in a Harman. Appling County to be exact. What you are looking at is sand. this is sand that fell through the air holes in the burnpot. This ruins igniters and slows ignition times. If you are burning these pellets or pellets like these in your Harman, I would suggest buying a spare igniter or two...oh, and add that cost of the igniter to the "deal" you got on the pellets and see if a super premium brand is really that much more expensive.
