Today I contacted PE directly and spoke to a technician regarding stove top temps. I am new to a steel stove and I wanted to verify the temps I have been burning at would not over fire the stove. I did not see any temp ranges in the manual. The tech advised the temp range they recommend are between 300 f to 750 f, and added that 750 f will not hurt the stove in any way. She went on to explain that all the internal parts are stainless steel and if the stove was burned in the 1000 F to 1200 f range the internal parts could potentially warp. These temps are measured on stove top under the trivet. I don't plan on burning it over 750 f, but I think it could climb to 900 easily if left open too long. Just thought I'd pass on the info.
