System water pressure adjustment
The filling pressure with system cold, read on the boi-
ler water gauge (detail 2 - fig. 24), must be approx 1.0
bar. If the system pressure falls below minimum va-
lues, the boiler stops and fault F37 is displayed. Pull
out the filling knob (detail 1 - fig. 24) and turn it coun-
ter-clockwise to return it to the initial value. Always clo-
se it afterwards.
Once the system pressure is restored, the boiler will
activate the 200-second air venting cycle, indicated on
the display by Fh.
To prevent boiler shutdown, it is advisable to periodi-
cally check the pressure on the gauge with system
cold. In case of a pressure below 0.8 bar, it is advisa-
ble to restore it.
