What it is

The Ferroli 39849800 is an air separator fitted on the flow pipe of the appliance. It removes entrained air from the heating circuit water as it leaves the boiler. It is used across the Ferroli Modena HE and T-ONE 30C HE appliance families.

Signs this part needs replacing

  • Persistent gurgling or rushing water noise from the boiler
  • Repeated airlocks in the heating circuit after bleeding radiators
  • Radiators heating unevenly or cold spots at the top
  • Water weeping or staining around the flow pipe connection
  • Circulation problems that return shortly after venting the system

Before you order

  • Confirm your appliance model against the fit list above
  • Check the variant, as NG and LPG versions are listed separately
