Forinstallation,itisadvisabletocontactspecialisedpersonnel.
The boiler must only be used for the application foreseen by
themanufacturer. The manufacturer shall not be liable for any
damage to persons, animals or property due to errors in instal-
lation,calibration,maintenanceorduetoimproperuse.
The safety and automatic adjustment devices must not be
modied,duringthesystemlifecycle,bythemanufactureror
supplier.
This appliance produces hot water, therefore it must be con-
nected to a heating system and/or a domestic hot water mains,
compatiblewithitsperformanceandoutput.
In case of water leakage, close the water supply and contact
theTechnicalAssistanceServiceimmediately.
In case of absence for long periods time, close the gas supply

Boiler use requires to strictly observe some basic safety rules:
Do not use the appliance in any manner other than its intended
purpose.
It is dangerous to touch the appliance with wet or damp body
partsand/orinbarefeet.

For better use, remember that:
- a periodic external cleaning with soapy water not only improves
its aesthetic aspect but also preserves panelling from corrosion,
extending its life cycle;
- if the wall-mounted boiler is enclosed in pendant furniture, leave
at least 5 cm for ventilation and maintenance;
- installation of an ambient thermostat will favour a greater comfort,
a more rational use of the heat and energy saving; the boiler can
also be connected to a programming clock in order to manage
ignitionandswitchingoffduringthedayorweek.
2A IGNITION
First ignition must be carried out by personnel from the Technical
AssistanceService.Atthesametime,ifitisnecessarytoputthe
appliance in service again, carefully follow the described opera-
tions.
To start-up the boiler it is necessary to carry out the following op-
erations:
- power the boiler

- turn the mode selector (1-g.1a)tothedesiredposition:
Summer mode: turning the selector to the symbol summer
(g.2a) the traditional function of only domestic hot water is acti-
vated.Ifthereisadomestichotwaterrequestthe digital display
shows the hot water system temperature, the icon to indicate the

Winter mode: by turning the mode selector within the area mar-
ked(g.2b),theboilerprovidesdomestichotwaterandheating.
If there is a heat request, the boiler switches on and the digital
monitor indicates the heating water temperature, the icon to in-
dicateheatingandtheameicon(g.3a).Ifthereisadomestic
hot water request, the boiler switches on and the digital display
shows the hot water system temperature, the icon to indicate the

Pre-heating(faster hot water):rotate the domestichot water
temperatureadjustment knob (2- g. 1a)to the symbol
(fig.5a), to activatethe pre-heating function.Thisfunction

temperature of the heating water or the domestic hot water,
accordingtothecurrentrequest.Duringburnerignitionfollow-
ing a pre-heating request, the monitor indicates the symbol

Environment Automatic Adjustment System Function (S.A.R.A.)
g. 7a
By setting the heating water temperature selector to the area marked
byAUTO-temperaturevaluefrom55to65°C-theS.A.R.A.self-
adjusting system is activated: the boiler varies the delivery tempera-
tureaccordingtotheclosingsignaloftheambientthermostat.When
the temperature set with the heating water temperature selector is
reached,a20minutescountbegins.Ifduringthisperiodtheambi-
ent thermostat still requests heat, the value of the set temperature
automaticallyincreasesby5°C.
Whenthenewvalueisreached,other20minutescountbegins.
If during this period the ambient thermostat still requests heat, the
valueofthesettemperatureautomaticallyincreasesby5°C.
This new temperature value is the result of the temperature set manu-
ally with the heating water temperature selector and the increase of
+10°CoftheS.A.R.Afunction.
After the second cycle the temperature value should be kept at the
setvalue+10°Cuntiltherequestoftheambientthermostatismet.
