What it is

The Alpha burner injector 1.024391 is an 8.5 mm gas injector used in Alpha CD35C boilers. It meters the gas supply into the burner, where the gas is mixed with air for combustion. Correct injector sizing is what sets the burner's heat input, so the 8.5 mm bore must match the appliance and gas type.

Signs this part needs replacing

  • Burner flame is weak, lazy or uneven across the burner
  • Yellow or lifting flame instead of a steady blue flame
  • Sooting or blackening around the burner and heat exchanger
  • Boiler fails to ignite, or locks out shortly after ignition
  • Reduced heat output with no other obvious cause

Before you order

  • Confirm your appliance model and GC number against the fitment list above
  • Check the existing injector is stamped or measured at 8.5 mm
  • Confirm the gas type the boiler is set up for, as NG and LPG injectors differ
  • Work on gas-carrying components must be carried out by a Gas Safe registered engineer
