USING THE BOILER.

Before ignition make sure the heating system is filled with water
and that the manometer (8) indicates a pressure of 1 - 1.2 bar.

relative temperature is shown on the display via the indicator
(19). Moreover, the temperature level that can be selected is
shown on the indicator (22).
• Winter (
): in this mode the boiler works both for producing
domestic hot water and for central heating. The DHW tem-

relative temperature is shown on the display via the indicator

shown on the indicator (15).
From this moment the boiler functions automatically. With no
demand for heat (central heating or domestic hot water pro-
duction) the boiler goes to "standby" function, equivalent to
the boiler being powered without presence of flame. Each time
the burner ignites, the relative flame present symbol is displayed
(11) with relative output scale.
