So I checked the temp of my ss liner through the old Superior fireplace name plate two feet above the insert. I pointed the Infrared laser in there and the liner read 140 for a temp the insert stove top was over 600. One I think its cool because not every insert owner can check the flue temp. Two For the stove being so hot wouldnt you think the flue temp would be hotter? Whats your opinion of this. Could I burn the insert hotter?
