What it is

The air vent pipe - heat exchanger is a pipe component used on Potterton Heatmax Combi HE boilers. It forms part of the heat exchanger air vent arrangement, allowing air to be released from the appliance so the heat exchanger and system water circuit can operate without trapped air. It is supplied under part number 5120223.

Signs this part needs replacing

  • Trapped air in the heat exchanger, causing noisy operation or gurgling
  • Repeated air-related lockouts or ignition faults after venting
  • Water weeping or staining around the vent pipe connection
  • Corrosion, scaling or a blocked vent pipe preventing air release
  • Visible damage, cracking or deformation of the pipe

Before you order

  • Confirm the boiler model from the data badge, not just the front casing
  • On a Heatmax Combi 33 HE, check the serial number against FMN 1112 to select the correct version
  • Compare the existing pipe against the part number 5120223 before fitting
  • Check the pipework and connections around the heat exchanger for other causes of air ingress
