What it is

This is a spacer for the heat exchanger, supplied under part number 721017001 and manufactured by Potterton. It is listed as a five element shim and is used on Potterton Titanium gas boiler models. The part sits within the heat exchanger assembly to hold the element spacing and sealing faces correctly.

Signs this part needs replacing

  • Weeping or staining at the heat exchanger joint where the spacer sits
  • Visible distortion, brittleness or flattening of the existing spacer
  • Repeated water loss traced to the heat exchanger assembly
  • The spacer is found misaligned or disturbed when the heat exchanger is stripped

Before you order

  • Confirm the boiler model and, where applicable, the serial number prefix shown on the data badge
  • Check the existing spacer against part number 721017001 before fitting
  • Verify the heat exchanger element count and layout on the appliance being worked on
  • Inspect the sealing faces and associated gaskets, as these are separate items and are not supplied with this part
