System water pressure adjustment
The filling pressure with system cold, read on the boiler water gauge, must be approx. 1.0 bar. If the system pressure
falls to values below minimum, the boiler card will activate fault F37 (fig. 15).
fig. 15 - Low system pressure fault
Operate the filling cock (detail 1 - fig. 16) and bring the system pressure to a value above 1.0 bar.
At the bottom of the boiler there is a pressure gauge (detail 2 - fig. 16) to show the pressure even when there is no power
supply.

Once the system pressure is restored, the boiler will activate the 180-second air venting cycle indicated on the
