Greetings from South Central Pa. I was placing a temperature gauge on a Quadrafire Isle Royale stove yesterday and realized that because it has a stainless rigid liner coming off of the top of the stove ........that my preferred location was not "doable" ....(magnets do not stick to stainless).....this brought up a question that I've never had answered....and I just took an educated guess......Maybe someone with an Quad Isle Royale can help me here??? I ended up fixing the magnetic temp gauge to the overhanging "flange" on the top right of the stove. It seemed logical. What I mean is that the front of the stove is "crowded" by the large double doors. (my second choice would be above and slightly to one side of a door)... So the joint where the top of the stove meets the front wall (it angles slightly down and overhangs 3/4") seemed like a good choice......Thanks in advance..I know that I will get great guidance here..(as always).
