How a thermostat-controlled gas fireplace works

When you connect a gas fireplace to a thermostat, it starts communicating with the gas valve via low-voltage signals.

Here are the detailed working steps –

  • The thermostat senses the temperature of your room.
  • If the temperature drops below the set point, it sends a signal.
  • When igniting the fireplace, the gas valves open
  • After reaching the desired temperature, the valve closes, and the flame shuts off.

It is an automatic cycle that provides steady comfort without requiring consistent manual input.

Understanding Millivolt systems

Many gas fireplaces, especially older ones, use millivolt systems. They make their own electricity using a standing pilot flame.
