What it is
The Ariston 65116392 is an automatic air vent used in Ariston ONE series gas boilers. It continuously releases trapped air from the heating circuit, helping to prevent airlocks, circulation noise and localised overheating. It is a serviceable component fitted within the appliance's hydraulic assembly.
Signs this part needs replacing
- Persistent gurgling or rushing water noise from the boiler or pipework
- Air continually collecting at high points in the system or in radiators
- Repeated pressure loss or the boiler requiring frequent topping up
- Water weeping or dripping from the vent body
- Boiler locking out or cycling shortly after start-up with air-related fault codes
Before you order
- Confirm your appliance model against the fit list above, as the same model name can appear in more than one variant
- Check the GC number on the appliance data badge against your model's listing
- Compare the existing vent's body, connection and orientation with the part before ordering
- If the system has been drained, plan to vent and re-pressurise the circuit after fitting
