Asked by Barbara Donahue

The sensor would also turn off when the internal temperature fell below 90 degrees.

Here's what to ask for...

  • Line voltage thermostat,
  • mechanical non-programmable,
  • switch-type SPST,
  • switch action close-on-rise.

"Line voltage" as the fan is probably 120vac. SPST. Single switch, on and off.

It's actually a cooling stat. The switch will close on temp rise as if to turn on a cooling fan on temp rise. Think: it's trying to cool the fireplace. Actually, it's blowing the hot air into the living space. Fire goes out; temp drops below preset (90); fan goes off.

Needs to be installed by an electrician. Easy.
