accompanying instructions about water quality, before filling
the heating system.
z Push and open the control panel cover.
z Turn the Space heating water temperature knob (fig. 46,
pos. 8) and DHW temperature knob (fig. 46, pos. 10)
counterclockwise to the "0" position.
z Turn the vent key a quarter rotation to undo the boiler
door lock (fig. 47, see detailed picture).
z Push the fastener down (fig. 47) and open the boiler
door.
z 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.
z Loosen the cap of the automatic air vent (fig. 48) by
turning one rotation counterclockwise.
