What it is

The BURNER - COMPLETE (FS90) is a complete burner assembly manufactured by Potterton Commercial, supplied under part number 5142411. It is the combustion component that delivers and ignites the gas/air mixture within the appliance. This assembly is specified for Potterton Commercial Sirius 2 and Sirius 3 boilers using the FS90 burner designation.

Signs this part needs replacing

  • Repeated flame failure lockouts or failure to establish a flame at ignition
  • Visible heat damage, distortion or corrosion on the burner head or body
  • Persistent sooting or uneven flame pattern across the burner
  • Combustion readings that cannot be brought within tolerance by adjustment alone
  • Gas leakage or deterioration at the burner assembly joints

Before you order

  • Confirm the appliance model and that the existing burner is the FS90 designation
  • Check the part number on the existing burner against 5142411 where it is still legible
  • Verify the boiler range, as the FS90 unit is used on both Sirius 2 and Sirius 3 variants
  • Work on gas-carrying components must be carried out by a competent, registered engineer
