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").
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 ELEC-
TRIC 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 technical 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 supply, switching on and off" on page 7).
• After the Fh cycle, the display will show the winter mode screen (fig. 11); do the temperature adjustments: heating
flow and DHW outlet (fig. 14 and fig. 15). Check if the value of the flue parameter, P68 - *** '- Transparent Parame-
ters Table' on page 34 ***, 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 pre-
sent in the supply system ( and cap. 3.1 "Adjustments" on page 32).
• Put the boiler in DHW or heating mode (see cap. 1.3 "Connection to the power supply, switching on and off" on
page 7).
• 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 draw-off present: the faucet symbol flashes on the display and the flame appears when
the burner ignites.
• Do the combustion check as described in par. "Checking the combustion values" on page 32.
