What it is

The Potterton 986335 is a gasket for the ignition and ionisation unit used on Potterton Commercial boilers. It seals the electrode assembly where it passes into the combustion chamber, protecting the ignition and flame sensing path from leakage and heat damage. The part is listed under electrodes in the Potterton Commercial spares range.

Signs this part needs replacing

  • The gasket is cracked, brittle or hardened and no longer seals against the electrode body
  • Soot staining or heat marking around the electrode mounting point
  • Ionisation or flame sensing faults causing lockouts or nuisance shutdowns
  • Repeated ignition faults traced to the electrode assembly area

Before you order

  • Confirm the appliance model and kW rating against the fit list above
  • Check the part number 986335 matches the number on the existing gasket or the manufacturer's parts listing
  • Inspect the ignition and ionisation electrode itself for damage or wear while access is available
  • Check the electrode mounting face for corrosion or pitting before fitting a new gasket
