Where and how do you mount a thermometer on the flue, or pipe? Or you just take readings with handheld infrared thermometer? I'm waiting for a stove thermometer to arrive in the mail, along with the moisture tester I ordered a month ago.Having done much oak and much pine lately, I can second @Highbeam : for softwoods (pine at 15-16%) I don't go 30 minutes. For (red, 18%) oak, I do. But I do keep an eye on my flue temp, and (given my tall chimney) "full throttle" means i go full, and slowly dial back keeping the flue below 900-950 F once it gets hotter.
