What it is
The Ravenheat 5015015 is an automatic air vent (air purge valve) for Ravenheat gas boilers. It continuously releases trapped air from the heating circuit, helping to prevent airlocks, noise and poor circulation. The valve is a Caleffi 502 FAT type unit.
Signs this part needs replacing
- Water weeping or dripping from the vent body or cap
- Persistent gurgling or air noise in the system after bleeding
- Boiler overheating or locking out due to trapped air
- Scale or corrosion visible around the vent
- Vent fails to discharge air when the system is bled
Before you order
- Confirm your boiler model and GC number against the fitment list
- Check the existing valve is marked 5015015
- Isolate the appliance and depressurise the system before removal
- Check whether the vent is fitted with an isolation valve
