What it is

The Potterton flow manifold FS105 - 160KW, part number 5132203, is a hydraulic component used in Potterton Commercial Sirius FS boilers. It forms part of the boiler's water circuit, directing flow through the appliance's heat exchanger and heating system. It is listed within the diverter valve group of Potterton Commercial spares.

Signs this part needs replacing

  • Water weeping or visible leakage from the manifold body or its joint faces
  • Loss of system pressure that cannot be traced to any other part of the circuit
  • Reduced or uneven heat output from the boiler despite correct settings
  • Overheating, noise or flow-related faults reported by the boiler controls
  • Scale, corrosion or debris build-up restricting flow through the manifold

Before you order

  • Confirm the boiler model against the fit list, as the manifold serves the FS 90-105 and FS 130-160 ranges
  • Check the part number 5132203 and the FS105 - 160KW marking on the existing component
  • Isolate the electrical supply and shut off the water and gas before any work begins
  • Inspect the surrounding pipework and seals so that any associated parts can be replaced at the same time
