pilot light

A pilot light is a small gas flame, usually natural gas or liquefied petroleum gas, which serves as an ignition source for a more powerful gas burner. Originally a pilot light was kept permanently alight, but this wastes gas. Now it is more common to light a burner electrically, but gas pilot lights are still used when a high energy ignition source is necessary, as in when lighting a large burner.
The term "pilot light" is also used occasionally for an electrical indicator light that illuminates to show that electrical power is available, or that an electrical device is operating. Such indicators were originally incandescent lamps or neon lamps, but now are usually LEDs.

    Glow worm Capricorn burner pressure?

    Hi a bit of a blast from the past here. Does anyone know the burner pressure this backboiler should be? The pilot light knocks the boiler off every time it fires up making me think that It's burning to high and pulling the pilot away from the thermocouple. Any ideas ?
