Initial operating procedures
If the boiler is installed inside the apartment, make sure that
all provisions relating to the air inlet and room ventilation (in
compliance with current legislation) are respected.
Check the water pressure on the display regularly and make sure
that the fi gure is between 0.6 and1.5 bar when the system is cold.
If the pressure is just under the minimum value the display will
request a fi lling procedure.
Re-establish the correct pressure by fi lling loop.
If the pressure drops very frequently, there may be a water leak at
some point in the system. If this is the case a plumber should be
contacted.
