The Baxi spark ignition electrode is responsible for making the spark that starts off combustion within the appliance. The flame sensing electrodes are responsible for monitoring whether there is a flame present in the burner. This is an important task that ensures the boiler doesn't keep supplying gas while no flame is present.
