2.8 Filling the heating system and eliminating air
C
A
NOTE: llthesystemviathellingtap(A) making sure the boiler is electrically
powered.
NOTE:eachtimetheboilerispoweredup,theautomaticventingcycleiscar-
ried out.
NOTE: the presence of a water alarm (A40,A41orA42) does not allow the
venting cycle to be carried out.
Fill the heating system as follows:
- openthellingtap(A) turning it counterclockwise
- then access the Info menu ( “4.3 INF O menu ”,itemI018),tocheck
that the pressure value reaches 1-1.5 bar
.1
5
.
NOTE: ifthemainspressureislessthan1bar,keepthellingtap(A) open
during the venting cycle. Close it when the cycle has ended.
To start the venting cycle:
- switcho󰀨theelectricalsupplyforafewseconds
- connectthepoweragain,leavingtheboilerOFF
- check that the gas tap is closed.
At the endofthecycle,ifthecircuitpressurehasdropped,openthellingtap
(A) again to bring the pressure back up to the recommended value (1-1.5 bar).
The boiler is ready after the vent cycle.
- Remove any air in the domestic system (radiators, zone manifolds, etc.)
using the bleed valves.
- Once again check that the system pressure is correct (ideally 1-1.5 bar) and
restore the levels if necessary.
- Ifairisnoticedwhenoperating,repeattheventcycle.
- Oncetheoperationsarenished,openthegastapandignitetheboiler.
At this point it is possible to carry out any heat request.
2.9 Draining the heating system
Beforedraining,settheboilertoOFFandshuto󰀨theelectricalsupplysetting
thesystem’smainswitchto“o󰀨” .
- Close the heating system’s taps (if present ).
