3.2 Commissioning
Before lighting the boiler
•Check the tightness of the gas system.
•Check correct expansion vessel precharge.
•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.
•Fill the trap (see cap. 2.7 "Condensate drain connection").
IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED
B
THERE MAY BE RISK OF SUFFOCATION OR POISO-
NING 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 draw-off 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 te-
chnical data table or in any case the tolerance provided for by the regulations.
•Power the boiler electrically, the display shows the software version number of the control unit
and display and then FH and Fh air venting cycle (see cap. 1.3 "Connection to the power sup-
ply, switching on and off" on page 305).
•After the Fh cycle, the display will show the winter mode screen (fig. 11); do the temperature adju-
stments: heating flow and DHW outlet (fig. 14 and fig. 15). Check if the value of the flue para-
meter, P68 - *** '- Transparent Parameters Table' on page 333 ***, is suitable for the length of
flue installed.
•In case of gas change (G20 - G30 - G31 - G230), check if the relevant parameter is suitable for
the type of gas present in the supply system (Table 10 on page 333 and cap. 3.1 "Adjustments"
on page 330).
•Put the boiler in DHW or heating mode (see cap. 1.3 "Connection to the power supply, switching
on and off" on page 305).
•In Heating mode, do a request: the radiator symbol flashes on the display and the flame appears
when the burner ignites.
•DHW mode with hot water tank preparation in progress: the faucet symbol flashes on the display
and the flame appears when the burner ignites (after a few ignitions by the burner, the system
further adapts the optimum ignition point).
•Do the combustion check as described in par. "Checking the combustion values" on page 330.
