This Glow-worm electrode is designed for Flexicom, Ultimate, and British Gas boilers. An ignition (spark) electrode causes the spark that begins combustion within the burner. In contrast, flame sensing electrodes are responsible for checking if a flame is present in the burner to ensure 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 plumber.
