So, the Jotul 12's have a threaded plug in the back, which can be removed to expose the refractory cat chamber. They say to spin a 1/4" drill bit thru the refractory by hand, and then insert your probe in the hole. No mention of a probe that threads into the plug hole, or even of cementing the probe in place. Seems strange to me to have a probe hanging from nothing but the strength of some delicate 3/4" thick refractory board, especially for those of us using remote probes with wires than can be accidentally tugged, thus likely damaging the refractory. Any words of wisdom, here?
