There are two different types of electrodes, ignition electrodes and flame sensing electrodes.

The ignition electrode makes the spark that starts off combustion within the appliance and the flame sensing electrodes are responsible for ensuring there is a flame present in the burner.

This is an important task and if the flame is not detected the boiler knows to re-attempt ignition.
