It depends on your definition of high temp? I smoke at about 230 or so not much higher then that. You can keep the high temp stuff with Le and his Uds. The next thing is I use chunks and chips in my chip pan so they don't caught fire. I have left my smoker for a few minutes and it got to 300 and the chips never caught fire so I don't know exactly wht your problem is. Do you have a chip pan?
