Pilot Assemblies
The pilot assembly is one of the most important safety components in a gas fireplace. It holds the pilot flame and, in most systems, a thermocouple or thermopile that signals your gas valve it's safe to release gas to the main burner. When a pilot assembly fails, your fireplace typically won't light at all.
Signs You Need a New Pilot Assembly
- Pilot light won't stay lit — often points to a failing thermocouple or thermopile within the assembly.
- Fireplace won't ignite — the pilot may not be receiving or holding gas properly.
- Visible rust or damage — corrosion on the assembly can affect the flame and safety sensor.
- Weak or yellow pilot flame — a healthy pilot flame should burn a strong, steady blue.
What to Consider When Buying a Pilot Assembly
- Match your valve brand & model — pilot assemblies are typically designed for a specific valve manufacturer and model.
- Natural gas vs. propane — pilot orifices are sized differently for each fuel type.
- Millivolt vs. electronic ignition systems — confirm which ignition system your fireplace uses before ordering.
- Professional installation recommended — pilot assemblies connect directly to your gas valve and safety controls.
