Crown Engineering 02040 Oil Burner Electrode 9/16 in 4 in Insulator

Product Description

The CROWN ENGINEERING 02040 is an oil burner electrode designed to provide reliable ignition in residential and light commercial oil-fired heating systems. The electrode features a 9/16 inch outer diameter and a 4 inch insulator length, with a heavy 1/8 inch diameter tip. These dimensions are critical for proper spark gap positioning and consistent ignition performance. Licensed oil burner technicians and HVAC service professionals install this component as a direct replacement when electrodes show wear, carbon buildup, cracking, or misfiring symptoms.

This electrode is used in oil-fired burner assemblies where precise tip geometry and insulator length must match original equipment specifications. It fits applications in forced-air oil furnaces, oil boilers, and oil-fired water heaters where standard electrode configurations are required. Correct electrode placement relative to the nozzle is essential for proper atomized fuel ignition. The heavy tip design is suited for applications where additional durability under repeated spark cycling is needed.

Key Features

• 9/16 inch outer diameter for proper seating in compatible electrode holders
• 4 inch insulator length for accurate positioning within the burner assembly
• Heavy 1/8 inch diameter tip for increased durability under repeated ignition cycling
• Designed for oil burner ignition service in residential and light commercial heating equipment
• Replacement electrode format for routine maintenance or failure-driven service calls

Compatibility

Designed as an OEM-style replacement electrode for oil burner assemblies requiring a 9/16 inch OD, 4 inch insulator, heavy 1/8 inch diameter tip configuration. Verify burner manufacturer specifications and electrode holder dimensions before installation.

Installation Notes

Oil burner electrodes are typically serviced by licensed oil burner technicians or qualified HVAC professionals. Shut off power to the burner and close the fuel supply valve before removing or installing electrodes. Electrode gap and position relative to the nozzle tip must be set according to the burner manufacturer specifications using a proper electrode gauge tool. Avoid handling the porcelain insulator roughly, as cracks or chips will cause misfire or short-circuit conditions.
