What it is

The Ferroli 39801160 is an automatic air vent with a 1/2 inch connection, used on Ferroli gas boilers. It continuously releases trapped air from the heating circuit, protecting the pump, heat exchanger and radiators from air locks and corrosion. The vent supersedes manufacturer code 3980116/0.

Signs this part needs replacing

  • Water weeping or dripping from the vent body or cap
  • Visible limescale or corrosion staining around the vent
  • Boiler losing pressure repeatedly with no other visible leak
  • Gurgling or air noise in the heating circuit that does not clear
  • Radiators needing frequent bleeding despite no recent drain-down

Before you order

  • Check your boiler model against the fitment list above
  • Confirm the existing vent has a 1/2 inch threaded connection
  • Isolate the appliance and drain down before removing the old vent
  • Check the vent location on the pump or manifold so the replacement sits correctly
