The filling pressure read on the boiler water gauge (detail 2 - fig. 15) with system cold must be approx 1.0 bar. If the
system pressure falls below minimum values, the boiler stops and fault F37 is displayed. Pull out the filling knob (detail
1 - fig. 15) and turn it counterclockwise to return it to the initial value. Always turn it off it afterwards.
Once the system pressure is restored, the boiler will activate the 300-second air venting cycle indicated on the display
by Fh.
To prevent boiler shutdown, it is advisable to periodically check the pressure on the gauge with system cold. In case of
a pressure below 0.8 bar, it is advisable to restore it.
