What it is

The main injector nozzle is a Johnson & Starley gas-carrying component that meters gas into the burner on Intejan warm air units. It is listed under pilot burner and gas boiler spares for the Intejan range. The nozzle is a serviceable item and is replaced when the injector becomes blocked, worn or damaged.

Signs this part needs replacing

  • Sooting or a yellow, lazy flame at the burner
  • Weak, uneven or unstable flame at the injector
  • Ignition faults or the burner failing to light
  • Visible debris, corrosion or blockage in the nozzle orifice
  • Repeated lockouts or flame failure after cleaning

Before you order

  • Confirm the appliance model and GC number against the manufacturer's parts list
  • Check whether a main injector or a pilot injector is required for the fault
  • Compare the part number on the existing injector with 1000-0702090
  • Work on gas-carrying components must be carried out by a competent Gas Safe registered engineer
