FLAME SWITCH

The flame switch is a normally open sensor. When immersed in an active pilot flame, it will close electrical contacts to complete the circuit that allows its corresponding valve(s) to operate.

If the pilots go out – the contacts on the switch will open and shutdown power to the indicator lights and corresponding valves.

On a cold start, it may take 2 or 3 minutes for the flame switch to heat up and allow the indicator lights and solenoid valves to come on.

One flame switch may control one or two indicator lights, thermostats and corresponding burner solenoid valves.
