Navien Electrode 30026264A

The Navien 30026264A is an electrode used in the combustion circuit of NCB-CE ERP boilers. It sits in the burner assembly and forms part of the boiler's flame monitoring and ignition circuit. It is a serviceable component, intended for replacement when the electrode tip degrades or the boiler reports a flame-related fault.

• Boiler locks out or fails to establish a flame on start-up
• Repeated ignition attempts followed by a fault code
• Flame detected briefly, then lost during the firing sequence
• Visible damage, heavy sooting or erosion at the electrode tip
• Intermittent lockouts that clear on reset but return

• Confirm your boiler model and serial number against the fitment list above
• Check whether your appliance is the system or combination variant
• Inspect the existing electrode and its lead before ordering, as damage is not always confined to the tip
• Isolate the electrical supply and gas before any work on the combustion circuit
