Description

The 31762-005 Fuel Gun Assembly is a precision-engineered combustion component specifically designed for Wayne EHASR series oil burners. This assembly acts as the “core” of the burner’s firing system, housing the nozzle adapter and providing the path for high-pressure fuel and ignition.

Technical Specifications

• Part Number: 31762-005.

• Compatibility: Exclusively for Wayne Model EHASR (typically used in high-static pressure applications like pressure washers and space heaters).

• Components Included: * High-pressure oil line (static tube).

  • Nozzle adapter/base.

  • Electrode support hardware.

• Material: Heavy-duty brass and steel construction to withstand high heat and vibration.

Key Features

• Ready-to-Install: Pre-assembled to factory specifications, reducing downtime during complex repairs.

• Precision Alignment: Ensures the nozzle and electrodes are perfectly centered within the air tube for an optimal flame pattern.

• High-Pressure Rating: Engineered to handle standard residential and commercial oil pump pressures (100–150+ PSI).

Primary Function

• Fuel Delivery: Transports pressurized oil from the pump to the spray nozzle.

• Ignition Housing: Provides the mounting point for the electrodes, ensuring the spark is positioned correctly in the fuel spray.

• Flame Shaping: Holds the nozzle in the exact “Z-dimension” required to interact with the burner’s air diffuser for a clean, efficient burn.
