Gas Fireplace Switch Wiring

All the switch is doing is making or breaking a connection it is not wired up to standard 110 volts.

Gas fireplace switch wiring.

A generic low voltage switch from a electronics store or ripped out of a toy would probably do it for example a 12v spst. The thermopile in your fireplace puts out millivolts nothing near the 120v the light switch was designed for. If this is the case there will be no power to run the smart switch unless it is battery powered. Slide the provided spade connectors onto the stripped ends of the wires in the gas fireplace control panel.

Slide the spade connectors onto the spade terminals on the back of the switch in the control panel or connect them directly to the pigtail wires if installed. It s probably just a matter of finding a switch with a low enough on resistance. If the fireplace is a 120v control then in most cases you will need a neutral. When attempting to automate a fireplace with a smart switch you have a problem because a lot of switches require a neutral wire to be connected so they have constant power for the zwave radios to send and receive signals.

On the gas fireplaces i have installed the on off switch was a millivolt contact. It shows the parts of the circuit as streamlined shapes and also the power and signal links in between the devices.
