What it is

The gas inlet pipe is a complete assembly that carries gas from the boiler's inlet connection to the gas valve on Potterton Commercial Sirius appliances. It is supplied by Potterton Commercial as a complete gas inlet pipe, part number 5142431. The pipe forms part of the boiler's gas train and must be sound and correctly sealed for safe appliance operation.

Signs this part needs replacing

  • A smell of gas or a joint that fails a leak detection test around the inlet pipe
  • Visible corrosion, pitting or cracking along the pipe body
  • Distorted or damaged pipework at the union or valve connection points
  • Joints that cannot be made gas-tight after reassembly
  • Boiler failing to hold gas pressure during commissioning or service checks

Before you order

  • Confirm the appliance model and variant from the boiler data badge against the fit list above
  • Compare the existing pipe with the item offered to confirm the assembly matches, including the connection ends
  • Check the condition of the associated seals, olives and unions, as these may also need attention
  • Confirm whether the installation is the commercial Sirius variant, as domestic Potterton models use different gas train components
