USER
fBefore the installation, it is necessary to read carefully the technical instructions.
fBefore ignition, it is necessary:
•to read carefully the use instructions
•to ll the condensation collecting syphon as described on page 24
fBoiler installation must be performed in compliance with legal provisions (M.D.
12/04/1996 and R dossier) and to UNI 11528 2014 standard or to a relevant
installationstandardof a EECcountry. In anycase,it is necessary toremember to:
•Cleanthoroughlytheheatingsystemwithwaterbeforeconnectingtheboiler
to the system itself. In case of existing systems and/or particularly dirty, use
specic cleaning products having proven eectiveness, in correct quantities
according to producer's indications.
•If the system has a power of up to 350 kW and water used to ll the system
has a total hardness of 35°fr, it is necessary to proceed to its softening in
order to reduce hardness, while if it has a total hardness between 15°fr. and
35°fr., a conditioning treatment is enough, aiming at ensuring that water
features are in compliance with the conditions of the UNI 8065 standard. For
systems with power greater than 350 kW, it is necessary to soften the water
used for lling if its hardness is greater than 15°fr. These water treatments
are necessary also in case of system lling.
•Forsystemsfunctioningatlowtemperatures,watertreatmentmustbecarried

Boiler external commands
Outside the boiler, conveniently positioned in the property (usually by the installer or
by the person in charge of installing the electrical system), there are two devices that
must be used by the user. Their presence and features are prescribed by rules in force:
Omnipolar switch: it is usually positioned near the boiler and must completely isolate
theboiler fromdomesticmains supply. Itmust be usedeachtime the boilerneeds to
be electrically powered, or when power supply of the equipment has to be switched
o, e.g. in case of long inactivity periods (see "Safety mode" on page 9) or in
some alarm cases (see "Alarms - boiler shut-down" on page 33).
Ambient thermostat: it electrically commands to the boiler the activation or the
switching o of the heating system, in order to maintain ambient temperature
(detected by one of its sensors) approximately at a value set by the user. Current
regulations describe its positioning, temperature limits within which the user can
adjust it and the switching on and o periods of the heating system.

Hot water commands
As for hot water production, boiler was designed to be integrated in a system with
domestic hot water storage, usually combined with a solar system and supplied with
specic indicators and commands for domestic water adjustment supplied to users.
Only when a storage temperature probe is directly connected to the boiler, the use of
the keys and determines the temperature at which water in the storage
is heated. If there are no adjustment commands downstream of the boiler unit, this
one regulates water temperature to the user. Otherwise, adjustment of domestic water
temperature in the boiler will aect only the maximum available* temperature and the
"duration" of hot water availability.
(* if external systems, e.g. solar systems, do not supply heat).
More complex systems can manage directly both storage temperature (forcing, if
necessary, heating by the boiler) and temperature to the user. See documentation
supplied with the system or ask the installer or the designer for information.

at factory setting. 55°C.
Typical use
Preliminary operations
fMake sure that the gas cock is open.
fMake sure that the boiler is electrically powered and in OFF mode: only the
writing OFF is displayed.
Boiler activation
fPress key :
•once, in order to use boiler in Summer mode, i.e. use it for hot water production
only. The Summer mode is indicated on the display by the symbol and not
the symbol ;
•press it again in order to use boiler in Winter mode, i.e. use it both for heating
and for hot water production. The Winter mode is indicated on the display by
the symbols and are simultaneously displayed.
•press it again in order to use boiler in Only Heating mode, i.e. disable boiler
preparation(onlytherelevantanti-freezefunctionstaysactive).TheOnlyHeating
mode indicated on the display by the symbol and not the symbol ;
•at each further pressure of the key , boiler cyclically switches to the modes
OFF, Summer , Winter + and Only Heating .
fInWinter + mode, upon request by AmbientThermostat, burner switches
on and the produced heat is transferred, through thermal uid, to the property
heating elements. In case of simultaneous request of hot water, this last request
takes priority for the whole duration of the request itself. Since boiler preparation
requests have a limited duration in time, they usually do not aect room heating.
Temperature setting
Note: a correct setting contributes to create the conditions for energy saving.
Note: if a Low Temperature system Kit or an External Probe Kit is installed, refer to
heating system documentation for its temperature setting.
Note: the heating system temperature described here shall not be confused with
the ambient temperature set on the ambient thermostat.
fHeating setting: pressing keys and , it is possible to set heating
system temperature (the value, during setting, is displayed under the symbol
). In general, during advanced wintertime and/or in case of insucient insulation
of the property (or if the burner stays on for a long time, but ambient temperature
struggles to reach the value set on ambient thermostat), it is advisable to set a
highersystemtemperature.Ontheotherhand,ifambienttemperatureconsiderably
exceeds,duetothermalinertia,thevaluesetonthethermostat,systemtemperature
should be reduced. With the optional external probe kit, system temperature
is automatically set and the use of the keys and is dierent:

fHot water adjustment: pressing keys and , it is possible to set hot
watertemperatureintheboilerunitstorage(thevalueisdisplayedunderthesymbol
). As for hot water temperature, see also "Hot water commands" on page 6.
If hot water production system is missing, leave the domestic hot water
at factory setting. 55°C.
Anti-legionella function
At pre-established intervals, boiler in Summer or Winter mode heats up boiler water
automatically in order to eliminate any bacteria (in particular Legionella°spp.) which
tend to form in presence of still and lukewarm water. The activation, if at all, of function,
frequency and treatment duration can be set by the Technician.
Note: The anti-legionella function is not active when boiler is set to OFF or to Only
Heating mode .
Time and day setting
Note: after 20 seconds without pressing any key, the function is quit without storing.
The time and day setting is particularly important if time-related functions want to be

Low domestic water production
fCheck that domestic water temperature is not set to a too low value, in this case
adjust it (see "Temperature setting" on page 6);
fhave the gas valve adjustment checked;
fhave the domestic water coil pipe checked and, if necessary, have it cleaned.
N.B.: In areas where water is particularly "hard", it is advisable to install on
domestic water inlet a suitable device which prevents limescale precipitation;
toofrequentcleaning operationsofthe boilercoil pipearethusnot carriedout.
Boiler inactivity
Eects of inactivity periods can be relevant in particular cases such as in homes used for
few months a year, mostly in cold locations.
The User will have to evaluate whether switch the boiler to the safety mode and
disconnect all supplies or whether leave it set to OFF (powered) to use the anti-
freeze function. In general, the safety mode is preferred.When freezing may occur, it
is advisable to choose between pros and cons of the safety mode and of the stand-by/
anti-freeze mode.
Safety mode
fSwitch o the general switch on the electric supply line of the boiler;
fClose gas cock;
If temperature can go below 0°C, have the following operations carried out by
your technician:
•ll the system, including the boiler unit primary circuit and the relevant coil
pipe, with anti-freeze solution (except when system has already been lled
with this solution), or have it completely emptied. Should pressure have to be
restored (due to possible leakages) in a system already lled with anti-freeze
solution, its concentration might decrease and the anti-freeze protection might
no longer be ensured.
•in any case, have the condensation-collecting siphon emptied after unscrewing
its lower cap.
•have the domestic hot and cold water system emptied, including the domestic
water circuit and the boiler domestic water storage.
Note: The boiler is equipped with a system which protects the main components from
therareblockingcasesduetoinactivityinpresenceofwaterandlimescale.Theanti-
blocking system cannot work during the safety mode due to lack of power supply.
Before switching on the boiler, make sure that the circulating pump is
not blocked due to inactivity: in the middle of the cap there is a hole (should
there be a cap, remove it) that gives access to the rotor shaft; push and turn
it using a suitable tool, usually a "Phillips" screwdriver.
Stand-by and anti-freeze/anti-blocking function
When boiler is left to OFF for the inactivity period, it will be protected from freezing
through functions set in the control equipment which heat the concerned parts when
temperatures go below the minimum values predened in the factory. Anti-freezing
heating is reached through switching on of the burner and of the circulating pump.
Moreover, boiler in stand-by periodically activates main internal components to avoid
the rare blocking cases caused by inactivity in presence of water and limescale. This
happensalsowhenboilerisshutdown(redlighton),butonlyifsystempressureiscorrect.
In order for these systems to be active:
•boiler must receive power and gas supply;
•boiler must be left in OFF mode (writing OFF displayed);
•systemwaterpressuremusberegular(optimal:1÷1.5bar,cold,minimum0.5bar).
If, in case of gas supply interruption or boiler shut-down (red light on), for this or other
reasons, boiler cannot be switched on. In this case, the anti-freeze function is carried
out by activating circulating pump activation.
ATTENTION: anti-freezeprotectioncannotbe activatedincaseof lackofelectric
powersupply.Shouldthisbelikelytohappen,itisadvisabletopouragood-brand
anti-freeze solution in the heating system, following producer's indications.
It is necessary to ask directly the installer information about the
anti-freeze solution poured in the heating system at the moment of
installation.
The boiler, when power supply is restored, will check temperatures detected
by its probes and in case freezing should be suspected, veried through a
particular automatic check cycle, alarm 39 will be triggered. For details see
relevant description in paragraph "Alarms - boiler shut-down" on page 33.
It is recommended to have the domestic hot and cold water system emptied,
including the domestic water circuit and the boiler domestic water storage.
The anti-freeze function does not protect the domestic water cycle outside the
boiler.
"Room Anti-Freeze" function
Note:if youwant touse the"roomanti-freeze"functionavailablein many commercial
chronothermostats or thermostats, it is necessary to leave the boiler in Winter
mode + and NOT in OFF mode.
The "Room Anti-Freeze" function does not ensure protection of the domestic
water circuit outside the boiler, in particular of the areas not reached by the
heating system. It is therefore necessary to have the parts of the domestic hot
and cold water system emptied, including the boiler domestic water storage,
should these be likely to freeze.

Boiler Commissioning Warnings
iBoilercommissioning andservicingmustbecarriedout byqualiedtechnicians.
The conversion of a gas belonging to one family (natural or liquid gas) to one
belonging to a dierent family can be made also after the boiler has been installed, and
must be made by qualied personnel only. The expert will have to check:
a) that the data on the identication plate comply with those of mains power, water
and gas supply lines;
b) that the calibration of the burner is compatible with the boiler power;
c) the correct function of the fume exhaust duct;
d) that combustion, air infeed and fume discharge are carried out correctly based
on the provisions of the prevailing National and Local Standards (M.D. 12/04/96;
StandardsUNI-CIG7129/01and 7131/99;P.D. 412/93and followingamendments);
