I did not foil the tray, but plan to when I do low and slow cooks with the fire pot cover in place. I cooked some bone in pork chops last night that turned out great with nice grill marks, but once again didn't think about a photo until I was half done eating. I'll try and do better with the photos.
The first time I did a cook, everything went fine but a shutoff, I got an E-1 error (Exceeded high temp). I had the smoker set at 495º. I talked to Blaz'n Grill and was told to use a temp of 400º. (Yes, I failed to read the instructions that said set at 400º)
So last night I set the smoker at 400º and everything went as normal during shutdown and I still had temps on the grill grates of high 600º to low 700º.
