The Sime usually has two types of electrodes: ignition electrodes and flame sensing electrodes. The ignition electrode is responsible for creating the spark that starts off combustion 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.
