PRELIMINARY CHECKS
Before commissioning the Boiler and carrying out the functional tests, check that:
–
the system has been filled and the hydraulic circuit pressure, in a cold state, is correct
–
the flue gases are correctly discharged and there are correctly dimensioned vents
–
electrical connections and earth connection are correctly carried out
–
check that the type of gas is the right one, that the fuel supply line has been correctly built and that the fuel is available
–
hydraulic and fuel circuit taps are open
–
check that the condensate drain of the Boiler is not clogged
–
check that the rotors of the circulation pumps are not blocked.
COMMISSIONING
To start the Boiler after performing the preliminary checks it is necessary to:
–
set the regulation thermostats on the control panel to the correct temperatures
–
check that the release button of the safety thermostat inside the control panel is reset
–
correctly adjust the control panel devices according to the installed model
–
position the system “main” switch and the control panel “main” switch to “ON”
–
operate on the ambient thermostat or chronothermostat and activate a heat request
The Boiler will perform the ignition phase and will operate until the adjusted temperatures will be reached.

IMPORTANT
In case of
LOCK-OUT STOP
of the burner, refer to its technical manual.
CHECKS AFTER COMMISSIONING
Once the start-up has been performed, check that the appliance stops and then restarts:
–
by modifying the Boiler thermostat calibration
–
by operating on the control panel main switch
–
by operating on the ambient thermostat or chronothermostat.
Once that the stopping and starting test has been performed, proceed with the following operations:
–
check the tightness of the door gasket and repeat the adjustment in case of leakages
–
check the correct operation of pumps
–
check the Boiler stop by positioning the system main switch to “
OFF
”
–
check the safety thermostat triggering.
If all the conditions are met, start the Boiler, bring it to its full operation and collect the combustion data.
NOTE
The flame inspection window is equipped with a hose connector which can be used both as a pressure test connection and for
cooling the flame inspection window.
m
IMPORTANT
The burners can operate for a time
NOT longer than 24 hours
, after which it is necessary to stop and restart the burner.
