3.2 Commissioning
Before lighting the boiler
• Check the tightness of the gas system.
• Check correct prefilling of the expansion vessel.
• Fill the hydraulic system and make sure that all air contained in the boiler and the system has been vented.
• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
• Make sure there are no flammable liquids or materials near the boiler.
• Check correct connection of the electrical system and efficiency of the grounding system.
• Make sure the gas valve is adjusted for the gas to be used (see *** '- THROTTLE position and parameter setting'
on page 174 *** and fig. 31 on page 174 of cap. 3.1 "Adjustments").
• Fill the trap (see cap. 2.7 "Condensate drain connection").
B
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED THERE MAY BE RISK OF SUFFOCATION OR
POISONING DUE TO GAS OR FUMES ESCAPING; DANGER OF FIRE OR EXPLOSION. ALSO, THERE
MAY BE A RISK OF ELECTRIC SHOCK OR FLOODING THE ROOM.
First boiler ignition
• Make sure there is no drawing of hot water and room thermostat requests.
• Turn on the gas and check that the gas supply pressure ahead of the unit complies with the technical data table or
in any case the tolerance provided for by the regulations.
• Electrically power the boiler; the display will show the software version number and then Fh and FH air venting cycle
(see cap. 1.3 "Connection to the power supply, switching on and off" on page 157).
• At the end of the FH cycle, the winter mode screen (fig. 8) will appear on the display; make the temperature adjust-
ments: heating delivery and DHW outlet (fig. 12 and fig. 13).
• Check if the flue parameter value (""Sc" - Combustion Control Parameters Menu" on page 181) is suitable for the
length of flue installed.
• In case of gas change (G20 - G30 - G31), check if the relevant parameter is suitable for the type of gas present in
the supply system (""Sc" - Combustion Control Parameters Menu" on page 181 and cap. 3.1 "Adjustments" on
page 173).
• Set the boiler to DHW or heating mode (see cap. 1.3 "Connection to the power supply, switching on and off" on
page 157).
• In Heating mode, carry out a demand: the display shows the radiator symbol and the actual heating system tempe-
rature; when the flashing flame symbol appears, the burner is lit and the system is performing the calibration. Wait
for the end of calibration, indicated by the steady flame symbol.
• DHW mode with hot water drawing: the display shows the faucet symbol and the actual DHW temperature; when
the flashing flame symbol appears, the burner is lit and the system is performing the calibration; wait for the end of
the calibration, indicated by the steady flame symbol.
• Carry out the fuel check as described in par. "Checking the combustion values" on page 174.
