Question: My wife and I just purchased a Jotul F600CB. the dealer installed it for us and put a thermometer in the chimney. I broke the stove in as directed following the temperature guidelines, however getting that temp up to 400 is difficult, even with a strong draft. My question is this, is the stove-top temp the same as the temp in the chimney? Answer: The temperature in the center of the chimney pipe is as much as 50% higher than the outside surface temp. So: 400 = 600, etc. In addition, the stove temperature can be very different from the chimney temperature. It may be more important to monitor the stove temperature, and many of our forum users monitor both temperatures. The best place to monitor stove temperature varies with the stove and the setup. Often the user manual will specify the best location for a monitoring thermometer, if it doesn't our forum members can often suggest a good one.
