Nuway Electrode L/R Con/Div P26034N

The Nuway P26034N is an ignition electrode supplied for Nu-Way oil-fired boiler and burner assemblies, referenced as electrode L/R con/div A4-550. It forms part of the burner ignition circuit, where the electrode tip sits in the combustion air path and sparks across to the opposing electrode or earth to light the oil/air mixture. It is listed within the manufacturer's oil spares range.

• The burner fails to light, with no spark at the electrode tip
• Repeated lockouts on start-up that clear only after several attempts
• Visible erosion, pitting or heavy carbon build-up on the electrode tip
• Cracks, crazing or discolouration in the ceramic insulator
• Spark tracking or arcing to earth rather than across the electrode gap

• Check the appliance data plate and confirm the burner model and build reference
• Confirm the electrode orientation and configuration required for your burner
• Cross-check the A4-550 reference against the manufacturer's parts list for your appliance
• Inspect the existing electrode and its mounting position before removal to confirm the fit
