What it is
The Alpha automatic air vent, part number 1.019735, is a boiler component that automatically releases trapped air from the heating circuit. It is used on the Alpha Cd50S (LPG) appliance. Removing air from the system helps prevent noise, poor circulation and localised overheating during normal operation.
Signs this part needs replacing
- Water weeping or dripping from the vent body or cap
- Visible scale, corrosion or staining around the vent
- Radiators or the boiler needing frequent bleeding
- Gurgling or air noise in the system that continues after bleeding
- System pressure dropping with no obvious leak elsewhere
Before you order
- Confirm the appliance model matches the fitment listed above.
- Check the part number on the existing vent against 1.019735.
- Confirm the installation is the LPG variant of the Cd50S.
- Isolate the appliance and depressurise the system before removal.
