So I pulled an oooopsie when I cleaned the chimney a few weeks ago. I was so eager to try my new sooteater I forgot to take my Condar Flue thermomter out of the stove pipe. OOOOPS. Made quite the racket when the sooteater spinning at 2000 RPM went by it. Anyways, as soon as it happened I pulled it out. The probe rod had a slight bend to it but no obvious damage. Now surprise surprise, the temp reading is a bit off. When the stove is ice cold the thermometer reads a little lower than it used to. Here is a pic from Condar's site.....when it is at room temp my thermometers needle is at the "F" in FlueGard. Is there any way to adequately test this thing? Putting it in the oven was my first thought but that wont work because the coil is designed to be outside the pipe, so it would read way high. How about sticking the probe rod in a pot of boiling water? It would only verify the low end of the scale though. Any thoughts? It appears that I can loosen the screw and manually turn the face to correct for off temps.
