What it is

The Potterton Ignition Electrode, part number 5142399, is a boiler ignition component for Potterton Commercial appliances. It provides the ignition spark at the burner to light the gas during a call for heat. It is listed for use with Potterton Commercial Sirius 2 and Sirius 3 Fs models.

Signs this part needs replacing

  • The boiler fails to ignite and goes to lockout.
  • No spark is visible at the electrode during an ignition attempt.
  • Ignition is intermittent or the boiler makes repeated ignition attempts before firing.
  • The electrode tip shows heavy sooting, corrosion, cracking or physical damage.
  • The spark tracks to earth or arcs away from the burner instead of igniting the gas.

Before you order

  • Confirm the existing electrode is marked 5142399 or matches the Potterton part number.
  • Check the boiler model against the Fits list before ordering.
  • Inspect the electrode lead and connector if the ignition fault is intermittent.
  • Confirm the appliance is a Potterton Commercial boiler.
