Hey folks. From reading forums here, I have learned that a thermometer on (or probed into) the stove pipe is preferred for an accurate reading of flu temps. However, my stove sits on a hearth and is vented up my chimney making this a difficult proposition. I would have to get behind the stove and look up the chimney to view the thermometer. I just ordered a Condar stove top thermometer, but wonder at how much of a disadvantage I will be. Are there standard temp calculation adjustments I should make to the stove top temps to get a better idea of flu temps? Thanks in advance for your help!
