What it is

This is the flue separator gasket, part number 5132515, manufactured by Potterton Commercial. It seals the joint at the flue separator on Potterton Commercial gas boilers, preventing flue gases and condensate from escaping at that connection. The gasket is listed as a boiler spare within the O-rings, washers and gaskets category.

Signs this part needs replacing

  • Visible cracking, hardening or flattening of the gasket material
  • Soot staining or discolouration around the flue separator joint
  • Condensate weeping or water marks at the joint
  • Flue gas readings drifting outside the expected range for the appliance
  • A smell of combustion products local to the boiler casing during operation

Before you order

  • Confirm the boiler model against the fit list above, as the gasket suits specific Potterton Commercial GOLD and Sirius units
  • Check the part number marked on or near the existing gasket, where legible, and match it to 5132515
  • Inspect the flue separator faces for corrosion or damage before fitting, as a poor sealing face will not be corrected by the gasket alone
  • Isolate the gas and electrical supply and allow the appliance to cool before stripping the flue separator joint
