What it is

The sealed chamber assembly is a Potterton Commercial component used on Gold and Sirius gas boilers. It forms the sealed combustion chamber that separates the burner and flue path from the surrounding room air in these room-sealed appliances. It is supplied under Potterton Commercial part number 5118362.

Signs this part needs replacing

  • Visible cracking, distortion or heat damage to the chamber body
  • Deteriorated or perished sealing faces, allowing the chamber to lose its seal
  • Corrosion or staining around the chamber joints or fixings
  • Flue gas leakage or combustion readings that cannot be corrected by servicing alone

Before you order

  • Confirm the boiler model matches one of the appliances listed in the Fits section
  • Check the existing chamber against Potterton Commercial part number 5118362
  • Inspect the chamber seating, seals and fixings before fitting, as these may also need attention
  • Verify the appliance is isolated and safe to work on before dismantling the combustion chamber
