Been loving the pellet stove so far! I know it's almost over but she's been a lifesaver in this shoulder season. House stays nice and toasty! My question is... what is the optimum flame height? Mine varies between 3 inches high all the way to touching the tubes. I think I have her dialed in to right around 6" or so. Is that where I want to be? I've searched this forum and Google and can't seem to find a straight answer. I do that, then I see pictures on Harman's site of their stoves running with a bigger flame. What say you, pellet heads?
