Usually, there are two different types of electrode, Ignition electrodes and flame sensing electrodes.

Ignition electrode makes the spark that starts off combustion within the appliance

Flame sensing electrodes are responsible for checking if 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.
