My manual says you can extend your heat probe using 18-2 thermostat wire, but says maximum length of 100 ft. But then in the note below that it says it shouldn't be extended more than 25 ft and should not be ran into another room in the house. I don't get it, it appears to be contradictory to me. So is it 100 or 25 ft? Whats the point of extending it if not putting it in a different area or room? I was thinking of running it to my 1st floor so the stove would be running to keep that floor at the temp I want it, even though the stove is in the basement. Do you think that would be a problem?
