What it is

The Vaillant R2/R3 round outlet fan is a combustion and exhaust component used on Vaillant gas boilers. It sits in the flue gas path and moves products of combustion through the heat exchanger and out to atmosphere, while drawing the air the burner needs. It is supplied by Vaillant under part number 0020020008 as a single unit.

Signs this part needs replacing

  • The boiler locks out or fails to fire, with a fan or flue-related fault code shown on the display.
  • The fan becomes noisy in use, with rumbling, scraping or bearing whine audible from the casing.
  • The fan runs intermittently or not at all when the boiler is called for heat, so the sequence stalls before ignition.
  • Soot deposits, discoloured flue readings or repeated flame-failure faults point to reduced combustion air flow.
  • Visible damage to the fan housing, outlet spigot or impeller on inspection.

Before you order

  • Check the boiler's data badge and serial number, then match the part number 0020020008 against the appliance documentation.
  • Confirm the existing fan carries the same R2/R3 round outlet pattern, as the housing and outlet shape vary between fan assemblies.
  • Inspect the fan mounting gasket or seal and replace it if it is compressed, torn or hardened, so the flue path stays airtight.

Not sure which part?

Tell the parts assistant what it's going into — the appliance make and model, or the GC number off the data badge — and it will check this part is on the fit list.
