What it is

The GASKET - SIDE PANEL is a sealing gasket manufactured by Potterton for use on Potterton Commercial Sirius 2 and Sirius 3 FS series boilers. It seals the joint at the side panel, preventing flue gas or heat leakage from the casing and maintaining correct combustion and airflow conditions around the appliance. The part is identified by Potterton part number 5142333.

Signs this part needs replacing

  • Visible damage, splitting, hardening or flattening of the gasket material
  • Staining, soot marking or heat discolouration around the side panel joint
  • Side panel not seating correctly or rattling because the seal has degraded
  • Evidence of leakage at the panel joint during servicing or a flue gas analysis check

Before you order

  • Confirm the appliance model is a Potterton Commercial Sirius 2 or Sirius 3 FS unit
  • Check the existing gasket against part number 5142333 before ordering
  • Inspect the panel and fixing points for distortion that may also need attention
  • Replace the gasket whenever the side panel is removed for service work, if the existing seal is compressed or damaged
