1.4 SYSTEM HYDRAULIC PRESSURE ADJUSTMENT

The filling pressure with system cold, read on the boiler
pressure gauge, must be approx. 1.0 - 1.5 bar. If the system
pressure goes below minimum values, the boiler stops and
fault F37 is displayed. Turn the filling knob (see fig. 4) counter-
clockwise to bring it back to the initial value. Always close it
afterwards. Once the system pressure is restored, the boiler
will activate the air venting cycle indicated on the display by
Fh. To prevent boiler blocking, 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.
