Fill the heating system
To ensure a trouble-free operation of the boiler, read the
accompanying instructions about water quality, before filling
the heating system.
NOTICE
At initial start up, the boiler will start as soon as
the system pressure exceeds 15 psi (1.0 bar).
If the system pressure falls to below 3 psi
(0.2 bar) the boiler will stop and generate a fault
code.
Push and open the control panel cover.
Turn the Space heating water temperature knob (fig. 46,
pos. 8) and DHW temperature knob (fig. 46, pos. 10)
counterclockwise to the "0" position.
Turn the vent key a quarter rotation to undo the boiler
door lock (fig. 47, see detailed picture).
Push the fastener down (fig. 47) and open the boiler
door.
Remove the insulation cover of the pump group (fig. 47).
To purge the boiler, every radiator in the heating system
must have a purge facility. In some situations it may even be
necessary to provide extra purging facilities at certain loca-
tions. The boiler itself has an automatic air vent.
Loosen the cap of the automatic air vent (fig. 48) by
turning one rotation counterclockwise.
