What it is

The Ariston 999110 is a noiseless fan kit supplied by Ariston for the Microgenus 23 MFFI boiler family. The fan draws combustion air into the burner and pushes flue gases out through the flue system, so it sits at the centre of safe combustion and reliable ignition on these appliances.

Signs this part needs replacing

  • Bearing whine, rumbling or grinding from the fan area during or after firing
  • Fan failing to spin up on a demand for heat, sometimes with the boiler locking out
  • Intermittent ignition failure or flame loss linked to poor combustion air flow
  • Overheat or flue-related lockouts that clear and then return
  • Visible damage, cracking or heavy soiling on the impeller or fan housing

Before you order

  • Check the boiler data badge to confirm the model is a Microgenus 23 MFFI Edition 1
  • Confirm the gas type of the installation, as both LPG and NG variants are listed for this part
  • Inspect the existing fan housing, gaskets and flue connections for damage before fitting
  • Verify the part number 999110 against the manufacturer's parts list for your appliance
