I recently had a hearthstone manchester installed and the thermometer was on the stove top in the middle. Seems like a bad place for it since the stove top has air between that and the actual stove top. Can anyone tell me where the best place to put it is? The stove top will read 225 for example and the side of the stove reads 375. I want to make sure I'm not burning at low temps. Any help is appreciated
