Well, I dumped all the Kirkland pellets. vacuumed it out, (inside and out), (burn pot, chamber, hopper and as much of the auger as I could), put a partial load of Smokehouse in it from Sam's. Got it fired up, and waiting for the auger to purge of all the Kirkland. FWIW there was very little dust, and this is the first time I have done this to it.
Have it set to 425, currently sitting at 226 after about 12 min run time (after light off not total). Will report back once I see if it can reach my temps with Smokehouse. If so, I will remember to use those for cold weather work
