I have a winterwarm small that I have installed flush. I bought a thermometer for it to place on the door because that's the only place I can put on on it but i haven't received it yet . So my question is, is there a way I can gauge the door temp vs the actual stovetop temp? I fired it up over the weekend and of course the top got hot before the door did and so I just want to make sure I don't overfire it this winter because it's hotter on top than the door. Maybe there's not enough of a difference in the two to worry about it but I wanted to check with you guys.
