A Flame Sensing Electrode in a boiler’s heating system is a safety device that verifies if a flame is present in the burner.
It does this by detecting a small electrical current generated by the flame.
If the flame goes out, the electrode signals the boiler to shut off the gas supply, preventing potential safety hazards like carbon monoxide leaks.
