What it is

The Potterton 5132501 is a pilot injector with an 8.5 mm diameter, listed by the manufacturer as the Injector - Dia 8.5mm (WH46). It sits in the pilot burner assembly of Potterton Commercial gas boilers and meters the gas flow that feeds the pilot flame. It is a service item on the Gold and Sirius ranges.

Signs this part needs replacing

  • The pilot flame fails to light, or lights and then extinguishes
  • A weak or yellow pilot flame instead of a steady blue flame
  • The pilot flame lifts off the burner or burns unevenly
  • Visible debris, blockage or damage at the injector orifice
  • Repeated lockouts traced back to pilot flame failure

Before you order

  • Check the boiler model against the fit list above
  • Note the part number 5132501 marked on the existing injector
