So I have a Condor Probe Thermo... Have it installed on double wall stove pipe. It was pushed in all the way against the magnet that comes with it (about 1/2" away from the pipe). In order to get my Mansfield up to 500 I would have to run the probe temp up to 1000!! So tonight I thought I would pull the probe out a bit so that the gage is now about 1 and 1/2 inches away from the outer wall of the double wall pipe... Now It reads about 300 less..... There still has to be about 4" of probe inside the inner pipe, so I imagine that this is more of a real reading... I think I was getting false readings because it dial was reading heat off of the double wall pipe.. Thoughts? How do you have yours? Is it up against the pipe, or do you have it pulled out a bit? Thanks - Chris
