What it is
The NGN55-100 A4-1739 is an ignition electrode supplied under the Oil Spares brand and listed for Nu-Way oil-fired boiler applications. It forms part of the burner ignition circuit, where the electrode sits in the combustion air path and provides the spark that lights the oil/air mixture on start-up. It is a service consumable, not an appliance-specific spare for a single boiler model.
Before you order
- Read the existing electrode's markings and compare them against NGN55-100 and A4-1739 before ordering.
- Confirm the burner is a Nu-Way unit and that the electrode is the ignition electrode for that assembly.
- Check the ceramic insulator and electrode stem for cracks, carbon tracking or erosion, and replace as a pair where the burner uses two electrodes.
- Inspect the HT lead, terminal and electrode holder at the same time, as poor connections at these points mimic electrode failure.
