Crown Engineering 04040 Oil Burner Electrode Heavy Tip

Product Description

The CROWN ENGINEERING 04040 is an oil burner electrode designed for use in residential and light commercial oil-fired combustion systems. The electrode provides the high-voltage spark that ignites the fuel-air mixture at the burner nozzle. It features a 0.5 inch outer diameter ceramic insulator measuring 4 inches in length, with a heavy-style tip measuring 0.125 inches in diameter. Electrodes of this type are installed and replaced by HVAC technicians and oil burner service technicians as part of routine combustion maintenance or troubleshooting of ignition failure.

This electrode is suited for oil burner applications where a heavy-duty tip configuration is required. It fits into the electrode assembly of residential and light commercial oil-fired furnaces, boilers, and water heaters. The 4 inch insulator length accommodates standard electrode bracket spacing found in many common oil burner configurations. Technicians typically replace electrodes in pairs during annual tune-up service or when carbon buildup, cracking, or erosion causes ignition faults.

Key Features

• 0.5 inch outer diameter ceramic insulator body
• 4 inch insulator length for standard bracket spacing
• Heavy-style tip at 0.125 inches diameter for durable spark performance
• Designed for oil burner ignition electrode assemblies
• Compatible with residential and light commercial oil-fired combustion equipment

Compatibility

Designed as an OEM-style replacement electrode for oil burner ignition assemblies in residential and light commercial oil-fired heating equipment.

Installation Notes

Oil burner electrodes are serviced by qualified HVAC or oil burner technicians. Shut off power to the unit at the service switch and allow the burner to cool before accessing the electrode assembly. Electrodes should be gapped and positioned according to the burner manufacturer specifications for the specific nozzle size and head configuration in use. Handle the ceramic insulator carefully during installation to avoid cracking, which will cause ignition failure.
