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 277).
• 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 - table "11" on page 306, 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 "11" on page 306 and cap. 3.1 "Adjust-
ments" on page 302).
• Put the boiler in DHW or heating mode (see cap. 1.3 "Connection to the power supply,
switching on and off" on page 277).
• In Heating mode make a request. The radiator symbol flashes on the display and the flame
appears when the burner has ignited.
