Getting ready for my first season of burning.... Have double walled stove pipe, is this thermometer ok? I guess you just drill a small hole in the pipe and then a magnet holds it tight and seals it? http://www.homehardware.ca/en/rec/index.htm/Heating-Ventilation-Cooling-Home-Comfort/Heating/Chimney-Supplies/Miscellaneous/Stove-Pipe-Thermometer-with-Probe/_/N-2pqfZ67l/Ne-67n/Ntk-All_EN/R-I5541069?Ntt=stove+thermometer Was planning on using an IR thermometer for the stove top as well. What sort of temps should I be seeing on the probe and stovetop? Thanks!
