What it is
The Ferroli 39846290 is a pressure gauge fitted to Ferroli gas boilers in the Modena HE, Twist PRO and T-ONE HE ranges. It displays the water pressure within the heating system on the boiler's gauge dial, so the system can be checked as correctly filled and pressurised.
Signs this part needs replacing
- The needle is stuck and does not move as system pressure changes.
- The gauge reads noticeably differently from a known-good test gauge.
- The dial face is fogged, discoloured or unreadable.
- The needle sits below zero or off the scale when the system is at normal pressure.
- Water is weeping from the gauge body or its connection.
Before you order
- Confirm your boiler model and GC number against the Fits list above.
- Check the part number on the existing gauge is 39846290.
