What it is

The Dual Orifice Injector is a fuel delivery component manufactured by EOGB for use in EOGB Honeywell and Satronic boiler appliances. It meters and atomises the fuel supply at the burner, with two orifices governing the flow characteristics required by the appliance. It is a serviceable item and is replaced as a complete unit.

Signs this part needs replacing

  • Sooting or black smoke at the flue, indicating poor atomisation or an altered fuel pattern
  • Unstable or pulsating flame at the burner
  • Repeated burner lockouts that persist after nozzle and filter checks
  • A visible restriction, blockage or damage at the injector orifice
  • Rising fuel consumption without a corresponding change in load or settings

Before you order

  • Confirm the appliance model matches the EOGB Honeywell - Satronic fitment listed above
  • Compare the markings on the injector being removed with the replacement to confirm the orifice configuration is correct
  • Check the injector holder and fuel line for damage or contamination before fitting
  • Confirm whether the appliance requires the injector to be set or adjusted after installation
