What it is

The Potterton 5142158 is a burner assembly rated at 525 kW, supplied as BURNER ASSEMBLY 525KW. It is the combustion component for the Potterton Commercial Sirius FS 525 gas boiler, where it introduces and mixes the gas supply with combustion air and presents the flame to the heat exchanger.

  • Combustion readings that cannot be brought into specification by normal setting up
  • Visible heat damage, cracking or corrosion on the burner body or head

Before you order

  • Confirm the appliance is a Potterton Commercial Sirius FS 525

  • Verify the boiler's gas rating and installation type before fitting
  • Work on the gas circuit and combustion settings must be carried out by a competent Gas Safe registered engineer
