This Potterton special electrode is a spare part for Main HE, Performa SL and Suprima Boilers. An ignition (spark) electrode causes the spark that begins combustion within the burner while flame sensing electrodes are responsible for checking if there is a flame present in the burner to make sure that the Boiler doesn't keep supplying gas without a flame.
Please always refer to the manufacturer's instructions for the correct application. All parts should be fitted by a qualified gas-safe certificate plumber.
