What it is

The Ferroli 39835610 is a natural gas (NG) injector used in the gas train of selected Ferroli condensing boilers. It meters the gas flow into the burner, so its bore and seating must be correct for the appliance and gas type. It is listed by Ferroli for the Fertech and Optimax HE PLUS ranges shown below.

Signs this part needs replacing

  • Combustion readings drifting outside the appliance's specified CO2 or CO range with no other cause found
  • Unstable or fluctuating flame, or the burner failing to light cleanly
  • Visible blockage, debris or corrosion at the injector orifice
  • Damage or scoring to the injector seating or body on inspection
  • Gas rate that cannot be set to the data badge figure after servicing

Before you order

  • Confirm the appliance model and GC number against the manufacturer's parts list, as injectors differ by model and gas type
  • Check the boiler is set for natural gas, not LPG, before fitting an NG injector
  • Verify the existing injector marking matches the part number required for the appliance
  • Work on the gas train must be carried out by a competent Gas Safe registered engineer, with combustion analysis after fitting
