Assume lots of you are firing stoves up today if I am here in VA. It may frost tonight. 
Bought a magnetic thermometer that says to put on the pipe, but is that assuming single wall pipe? If so, should the thermo go somewhere on the stove or should I "calibrate" readings based on the selkirk doulble wall's insulating capabilities?
Thanks -
