I'm new to pellet grilling, but this seems to be way to much ash for a 2 hour grilling session. The ash was up to the igniter rod. The grill was started on the smoke setting, then bumped to 275 for 5 mins and then to high. The tri tip was "seared" on each side for 4 mins, and then the grill was turned down to 275. The tri tip was flipped throughout the cooking time. This is in a new Traeger Jr with their digital control and bbq delight apple pellets were used. This grill was also shutdown with the 10 min shutdown cycle that keeps the fire pot fan on. Any thoughts or input?
