Gas fireplace thermostat control

[Jerry Simon]

This Heatilator fireplace was labeled by the seller as broken, so I didn't try to light it. That said, what's with the thermostat to the side of the fireplace (& it ain't for the furnace)

Hmmm, never seen them place the fireplace thermostat that close before, though it would certainly cut down on reaching the set temp Most in my area just use the light switch only and turn it off when they're done, but one's that had the thermostat had them across the room (though I rarely see them). Certainly don't want to actually try to heat with it too much unless you just like giving money to the gas company. Have seen some with wireless remote control thermostats where they could just sit it near them and maintain the temp they wanted.

That thermostat is not the type approved for use with this fireplace. It is a horrible location for any thermostat. Note the decora wall switch above it. This type of single pole switch is commonly used for the low voltage systems on standing pilot systems, IPI ignitions, and line voltage for DSI systems.

Have a qualified hearth pro inspect the fireplace and verify which switch operates the fireplace. Most built in gas fireplaces mfd. since 1995 are heater rated meaning they can legally operate by a thermostat. Vented gas logs cannot.
