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

The Ignition electrode makes the spark that starts the flame within the burner.

The flame sensing electrodes are responsible for checking if there is a flame present in the burner.

This is an important safety device that makes sure the boiler isn’t still supplying gas without a flame.
