a Product use may cause some surfaces to
become extremely hot (the glass, the ex-
ternal surfaces, the handles, the smoke
outlet passage). Any contact between
clothing or body parts and these surfac-
es, including where accidental, may cause
burns or res.
■ Before performing work on parts of the
appliance that may be hot (e.g. top surface
panel, grilles, covers, door, settings devic-
es and control devices), take the necessary
precautions and use suitable protective
devices (glove, redoor opening tool or
other specic devices).
■ Since the glass becomes hot, make sure
that no person other than those experi-
enced in operating the appliance remain
in the area from where the heat emanates.
a Everyone (both children and adults)
should be informed of the risk of coming
into contact with hot surfaces.
■ Babies, young children, animals or anyone
else may experience burns as a result of
accidental contact. If there are any at-risk
subjects in the home, a protective barrier
should be installed. To limit access to the
appliance, install a safety gate to keep ba-
bies, young children and other at-risk sub-
jects out of the room and away from the
hot surfaces.
a This appliance is not for use by persons
(including children) with reduced physi-
cal, sensory, mental capacity or with a lack
of experience and knowledge, unless they
are helped or have been instructed on how
to use the appliance by the person who is
responsible for their safety.
■ Children shall not play with the appliance.
Cleaning and user maintenance shall not
be made by children.
■ Young children should be carefully super-
vised when they are in the same room as
the stove.
a If you expect that small children or vulner-
able adults may come into contact with
this appliance, the following precautions
are recommended:
■ Install a physical barrier such as a decora-
tive rescreen or an adjustable safety gate.
■ Install a switchlock or a wall/remote con-
trol withchild protection lockout feature.
■ Keep remote controls out of reach of chil-
dren.
■ Never leave children alone near a hot
stove, whether operating or cooling down.
■ Teach children to NEVER touch the stove.
■ Consider not using the stove when chil-
dren will be present.
a During the operation and/or cooling
phase, slight creaking noises may be
heard. This is not considered a defect, but
is a consequence of the thermal expansion
of the materials used.
d Do not install the product too close to
neighbors or in valleys that would cause
unhealthy air quality or nuisance condi-
tions.
d It is forbidden any unauthorized modica-
tion of the appliance.
d Do not stand or place objects which are
not heat-resistant within the prescribed
minimum safety distance.
■ This also applies when the appliance is
o. The appliance may be turned on by
somebody else or, where the appliance
is pre-congured, may be automatically
switched on (programmed or via remote
control), at any time.
■ Do not place food, drinks or other contain-
ers with liquids on parts of the appliance
or the surround, except for compartments
specically designated by the manufac-
turer for cooking or warming up food.

provided by the manufacturer and in compliance with all relevant
regulations. In particular, check:
- suitability of the room where the appliance is to be installed as
well as any restrictions
- the existence of any other appliances
- fresh air intake
- ventilation within the area where the appliance is to be installed
- sufficient clean air flow for combustion: air cannot be taken
from potentially polluted areas
- smoke evacuation system comprising a connecting flue pipe,
flue and chimney.
Installation may also include a series of operations to be carried
out correctly by enabled personnel and for which system com-
patibility must be guaranteed:
- connection to the air intake
- connection to the smoke evacuation system
- ventilation
- assembly and installation
- any necessary electrical or plumbing connections
- insulation
- start-up and operating tests, and where necessary calibration
and adjustment
- cladding and trims
- presentation of additional documentation as prescribed by the
regulations
- end user training by the installer on how to use and maintain
the appliance

AGE AND/OR INJURY MAY RESULT.
2 PRODUCT INFORMATION
2.1 PRODUCT DESCRIPTION
This appliance is:
- a heat generator designed to be run with pellets
- to be used solely for the purpose for which it was designed; all
other uses are to be considered improper and therefore dan-
gerous
- equipped with a flue evacuation fan which maintains the com-
bustion chamber in negative pressure.
The use of a fuel which can be easily transported and stored such
as pellets, facilitates the ease of use of this appliance.
Heat diffusion is also ensured by the Multifuoco System forced
ventilation system offering different personalised functions and
the option of ducting.
The control unit allows the user to manage a range of functions
and programmes, while the basic controls can also be managed
using the control panel on the appliance itself.
The pellets are loaded into the hopper manually and the ignition
is electronic.
An electronic control unit controls the pellet dosing into the grate
as well as the flue gas expulsion.
The unit controls the appliance to make sure it operates correctly.
Thanks to a series of safety devices, it signals any faults and, if nec-
essary, initiates the appropriate procedures.

2.3 SAFETY DEVICES
The appliance is equipped with the following safety and check
devices which stop the stove from operating if any faults occur
against over-firing and ensuring heaters is operating properly, in-
cluding ensuring visible emissions are minimized.
If any safety warnings or alarms are activated, please consult the
“ OPERATING INSTRUCTIONS ”.
Pressure switch:
controls the vacuum inside the appliance. The pressure switch is
activated if the correct operating conditions are altered (inappro-
priate use or installation, obstacles or blockages in the flue, lack
of maintenance, adverse weather conditions such as persistent
wind etc.). The pressure switch activates and isolates the supply
voltage to the auger, thus stopping pellet feed to the grate and
then initiates the appliance shut down process.
Fuel hopper thermal cut-out:
this is a thermal device with automatic rearming that serves to
safeguard the pellet hopper against excessive temperatures.
If the temperature of the hopper exceeds the safety threshold, the
device isolates the supply voltage to the auger, pellet feed to the
grate is stopped and the appliance shut-down procedure begins.
Smoke temperature probe:
this is connected to the electronic control unit and constant-
ly monitors the operating temperature. If during this phase the
smoke temperature:
a) exceeds the safety threshold, the electronic control unit isolates
the supply voltage to the auger, thus stopping pellet feed to the
grate and starting the appliance shut down process
b) falls below the minimum operating temperature, the appliance
stops and an acoustic alarm signal is activated.
Furthermore, if during the start-up phase a system malfunction is
detected, an acoustic alarm signal is activated.
Auger safety:
the operation of the auger is constantly monitored by the elec-
tronic control unit. In the event of a malfunction, an acoustic
safety signal is activated. The electronic control unit isolates the
supply voltage to the auger, thus stopping pellet feed to the grate
and starting the appliance shut down process.
Extractor fan safety:
the rotation of the extractor fan is constantly monitored by the
electronic control unit. In the event of a fan malfunction, an
acoustic alarm signal is activated. The electronic control unit iso-
lates the supply voltage to the auger, thus stopping pellet feed to
the grate and starting the appliance shut down process.
Electrical safety:
the appliance is protected by fuses in the event of a power surge.
Electronic control unit:
the electronic control unit signals and controls a series of events
including power and ignition failure.
d The safety devices are there to eliminate the risk of
damage or injury to persons, animals or objects. IT IS
FORBIDDEN to tamper with the safety devices or allow
any intervention to be carried out by non-qualied per-
sonnel.
2.4 CHECK DEVICES
The appliance is equipped with some check devices which are to
be used exclusively by personnel authorised to carry out fine tun-
ing operations during installation and maintenance procedures.
Pressure plug (A) : for measuring the pressure drop inside the
appliance.
DB9 serial port (B) : to carry out checks on the correct operation
of the product and any necessary maintenance operations. A re-
mote appliance-management system (GPRS or Wi-Fi) can be con-
nected to the DB9 serial port.
