What it is
The Ariston 65105894 is a 14 mm venturi used in the fan and combustion air circuit of Ariston CLAS HE R gas boilers. It creates a controlled pressure differential that the boiler uses to monitor air flow through the fan. It forms part of the fan and air pressure sensing arrangement rather than a complete fan assembly.
Signs this part needs replacing
- Boiler locks out or fails to fire, with fan or air pressure related fault codes
- Fan runs but the boiler does not prove air flow and will not ignite
- Whistling or unusual noise from the fan or air intake area
- Visible blockage, debris or damage at the venturi
- Intermittent operation traced to the air pressure circuit
Before you order
- Confirm the boiler model is Ariston CLAS HE R 12 NG or CLAS HE 12R
- Check the GC number against the appliance data badge
- Confirm the existing venturi is 14 mm
- Establish whether the fault lies with the venturi or the wider fan assembly
