WARNING
Congratulations on your selection.
Your modulating boiler is electronically adjusted and ignited.
• highly ecient;
• sealed chamber.
Unlike traditional boilers, your condensation boiler makes it possible to recover energy by con-
densing the water vapour contained in the ue gas; that is, with equal heat production, it con-
sumes less gas and furthermore, the ue gas contains fewer substances that are harmful to the
environment.
The materials used and the regulation system oer safety, high levels of comfort and energy sav-
ings so you can appreciate the maximum advantages of autonomous heating.
DANGER: Information marked with this symbol must be observed to prevent me-

WARNING
IMPORTANT
The manual must be read carefully in order to use the boiler in a rational and safe manner. It
must be stored with care as it may be necessary to consult it in the future. If the unit is trans-
ferred to another owner, the manual must accompany the boiler.
The rst ignition must be carried out by one of the Authorised Service Centres, which vali-
dates the warranty from the date on which it is performed.
The manufacturer declines all liability for translations of this manual from which incorrect in-
terpretations may result. It cannot be considered responsible for failure to observe the instruc-
tions contained in this manual or the results of performing manoeuvres that have not been
specically described.
DURING INSTALLATION
Installation must be carried out by qualied personnel who shall be responsible for compli-
ance with all applicable national and local laws and standards.
The boiler is used to heat water to a temperature that is lower than the boiling point and must
be connected to a heating system and/or a domestic hot water distribution network that is
compatible with its performance and its power.
The boiler must be supplied with Methane gas (G20) or Butane (G30) or Propane (G31).
The condensate discharge must be connected to the residential condensate discharge duct
and must be possible to inspect it (UNI 11071 and correlated standards).
The boiler must only be used for the purpose for which it was designed, furthermore:
• Itmustnotbeexposedtoatmosphericagents.
• Itmustnotbehandledbychildrenorunqualiedpersons.
• Preventincorrectuseoftheboiler.
• Avoidmanoeuvresonthesealeddevices.
• Avoidcontactwithhotpartsduringoperation.
DURING USE
It is prohibited and dangerous to obstruct, even partially, the air intakes for the ventilation of
the room where the boiler is installed (UNI 11071/08);
Repairs must only be carried out by Authorised Service Centres using original spare parts. There-
fore, in the case of a problem, deactivate the boiler only (see instructions).
If you smell gas:
• Donotturnonelectricswitches,thetelephoneoranyotherobjectthatcouldcreatesparks.
• Immediatelyopenupthedoorsandwindowstocreateanaircurrentthatcleanstheroom.
• Closethegascocks.
• Requesttheinterventionofprofessionallyqualiedpersonnel.

WARNING
Before starting the boiler, it is recommended to have professionally qualied personnel
check that the gas supply system:
• Isperfectlysealed.
• Isdimensionedfortheowratenecessarytotheboiler.
• Isequippedwiththesafetyandcontroldevicesrequiredbycurrentstandards;
• Makesurethattheinstallerhasconnectedthesafetyvalvedischargetoadischargefunnel.
The manufacturer is not responsible for damage caused by the water released when the safe-
ty valve opens if it is not correctly connected to a drain.
• Makesurethattheinstallerconnectedthe condensatesiphon discharge toa specic dis-
charge funnel (UNI 11071 and correlated standards), which must be implemented in order to
avoid the condensate from freezing and ensure its correct evacuation.
Do not touch the unit with wet or moist body parts and/or with bare feet.
If performing structural work or maintenance near the ue gas duct and/or the ue gas
exhaust devices or their accessories, turn o the unit and, when the work is completed, have its
eciency checked by professionally qualied personnel.

Regulation
Adjust the temperature of the domestic hot
water to a value that suits your needs.
Limit the need to mix hot water with cold water.
In this way you will appreciate the characteris-
tics of automatic regulation.
If the water is particularly hard, we recom-
mend regulating the boiler temperature to
below50°C.
In these cases, we recommend installing a wa-
ter softener in the d.h.w. system.
If the maximum ow rate of the domestic hot
water is too high so that a sucient tempera-
ture cannot be reached, request an Authorised
Support Technician to install a ow rate limiter.
Domestic hot water demand
When the boiler has a domestic hot water de-

The number indicating the pressure is dis-
played without a decimal point, and the letter
indicates the unit of measure (bar) (Figure 3.2).
Figure 3.2
OpenthellingcockinFigure3.1locatedun-
der the boiler and check at the same time the
heating circuit pressure on the display. The
pressure must be between 1 bar and 1.5 bar
(e.g. 1.3 bar in Figure 3.2).
When the operation is complete, reclose the
lling cock and bleed any air from the radia-
tors.
3.2 Heating
For rational and economic service, have an am-
bient thermostat installed.
Never turn o the radiator in the room where
the ambient thermostat is installed.
If a radiator (or convector) does not heat, check
if there is air in the system and that its cock is
open.
If the ambient temperature is too high, do
not adjust the radiator cocks but decrease
the heating temperature regulation using the
ambient thermostat or the heating regulation
keys16and17(Figure3.3).

3.3 Antifreeze protection
The antifreeze system, and any additional pro-
tections, protect the boiler from possible dam-
age due to freezing.
This system does not guarantee protection for
the entire hydraulic system.

-16-
USE
USEFUL TIPS
If the external temperature could reach values
below 0°C it is recommended to leave the en-
tire system on, setting the ambient thermostat
to a low temperature.
The antifreeze function is active even if the
boiler is in stand-by (Figure 3.4).
Figure 3.4
If the boiler is turned o, have a qualied tech-
nician empty the boiler (heating and d.h.w.
circuit) and empty the heating system and the
d.h.w. system.
3.4 Periodic maintenance
For ecient and regular boiler operation, it is
recommended to have it serviced and cleaned
at least once a year by technician from an Au-
thorised Service Centre.
During this check, the most important boiler
components will be inspected and cleaned.
This check may be performed within the scope
of a maintenance contract.
3.5 External cleaning
Before performing any cleaning
operation, disconnect the boiler
from the electric mains supply.
To clean, use a cloth soaked in soap and water.
Do not use: Solvents, ammable substances,
abrasive substances.
3.6 Operating anomalies
If the boiler is not operating and a code ap-
pearsontheLCDdisplaythatalternateswith
the letter Er and the message reset (see "Gen-
eral LCD characteristics" on page 8), the

This occurs only when the boiler has a demand
for domestic hot water.

To reset proper boiler operation
contact a technician at the Author-
ised Service Centre
Air bubble noises
Check the pressure of the heating circuit and
ll it if necessary, see section "Filling the heat-
ingcircuit"onpage15.
Low system pressure
Add more water to the heating system.
For the operation, refer to section "Filling the
heatingcircuit"onpage15.
The user is responsible for periodically check-
ing the pressure of the heating system.
If water must be added too often, have the
technical support centre check if there are
leaks in the heating system or the boiler itself.
Water leaks from the safety valve
Check if the lling cock is well closed (see "Fill-
ingtheheatingcircuit"onpage15).
Check from the "INFO" (information) menu
that the heating circuit pressure is not close to
3 bar. In this case it is recommended to drain
a part of the water from the system through
the air relief valves in the radiators in order to
reduce the pressure to a regular value.
In the case of malfunctions other
than those described above, shut
down the boiler as described in
see "Shut-o" on page 14 and
contact the technician from the
Authorised Service Centre.

3.8 Remote anomaly code
If the optional remote is connected to the boil-
er, a code can be shown on the central part of
the display that indicates a boiler anomaly.
The current anomaly is indicated by a numeric
code followed by the letter E.
The table summarises the possible codes that
can be displayed on the remote.
