What it is

The Vaillant flue restrictor (17mm/20mm) is a flue component used to regulate flue gas flow on liquid gas appliances. It is supplied under Vaillant part number 0020231184 and is intended only for liquid gas (LPG) installations. The restrictor is fitted as part of the flue system on compatible Vaillant HOME Regular appliances.

Signs this part needs replacing

  • Flue gas readings fall outside the manufacturer's stated tolerance during commissioning or servicing
  • The restrictor is missing, cracked, distorted or otherwise damaged on inspection
  • Combustion analysis cannot be brought within specification on a liquid gas appliance
  • Flue performance or plume behaviour is inconsistent with the appliance's expected operation

Before you order

  • Confirm the appliance model against the fitment list above
  • Check that the appliance is a liquid gas (LPG) unit, as this restrictor is only for liquid gas appliances
  • Confirm the required restrictor size is 17mm/20mm for the installation
  • Inspect the existing flue assembly to establish whether a restrictor is fitted and what condition it is in
