On the advice of this forum I purchased a stove top thermometer (Condor ChimGard). Fired up the stove last night. I placed the device on top of the stove (the part that protrudes into the room), the highest temp. reading the I had (after more than 2 hours), was 250 degrees. Far less than what I believe I should be getting. Even though the stove was producing a great amount of heat, had a great coal bed, and seemed to be burning great. What am I doing wrong? Any help would from someone who owns this model would be very greatly appreciated...
