I recently installed an Osburn Stratford and am looking for some input on burn temp, and for how to keep the glass clean. Since it does not have a temp gauge (like a wood stove flue pipe) I am a little unsure how hot it should be. I have used a laser thermometer to check the temp of the secondary burn tubes, which has been 700+ a few times. This seems pretty hot, but I’m sure the temp that a class A pipe can handle is quite a bit more than a black pipe for a wood stove. As for keeping the glass clean, even with burning well seasoned ash it gets dirty within a few hours of use. Should I burn it even hotter? I will also try keeping the wood farther away from the glass next time.
