any attempt to remove parts or to perform maintenance on the appliance can expose the
user to the risk of electric shocks. The stove contains parts which must be serviced by the
Authorised Service Centre.
- The stove is a heating appliance; its parts reach high temperatures and therefore touching
them without suitable precautions can cause severe scalds and burns. Pay special attention to
children.
- When moving the appliance, contact the Authorised Service Centre for removal and new
installation.
- Do not place your ngers or objects in the air vents.
There is a high speed fan inside the appliance which could cause severe personal injuries. Pay
special attention to children.
- Do not remain exposed directly to the hot air ow for too long.
Direct and prolonged exposure to hot air can be harmful to health.
Pay special attention in rooms with children, elderly or sick people.
- Should the stove malfunction, stop the appliance immediately, switch it off and contact
the Authorised Service Centre.
Continuingtousetheapplianceintheseconditionscancauseresorelectrocutions.
- If the supplementary air vent is not used (only for ducted models), check that the fan speed is
at zero (deactivated).
WARNINGS!
- When installing the stove, keep children away from the workplace.
Unexpected accidents could occur.
- Do not block or cover the stove body in any way or obstruct the vents on top.
Obstructingtheseventscancauseres.
- Do not use the stove in environments containing precision instruments or works of art.
The quality of these objects could undergo deterioration.
- Do not expose animals or plants to the appliance's direct air ow.

Positioning
The stove is supplied with an electric cable to be
connected to a 230V 50Hz socket, preferably
with a circuit breaker switch. Voltage variations
beyond 10% can endanger operation of the
stove (an appropriate residual current device
must be provided if not already existing).
The electric system must be according to
standards; especially check the efciency of
the earthing circuit. The cross-section of the
power line must be adequate for the power of
the appliance.
The stove must be level.
Verifytheweightbearingcapacityoftheoor.
The positioning of the stove inside the home
is fundamental in order to uniformly heat the
environment. Before deciding where to place
the stove, take into account that:
• Combustion air cannot be obtained from
a garage or a space without ventilation or
air exchange, but from an open or outdoor
space;
• The stove should preferably be installed in
a large room in the middle of the home to
assure the maximum circulation of heat;
• The stove must be connected to an earthed
socket (if the supplied cable is not long
enough to reach the closest socket, use a
suitable extension cord).
Safety distances for re protection
The stove must be installed while meeting the
following safety conditions:
• Minimum distance of 40 cm on sides and back
frommediumammablematerials.
•Easilyammablematerialsmustnotbeplaced
less than 80 cm from the front of the stove.
•Ifthestoveisinstalledonaammableoor,
a sheet of heat insulating material must
be placed between the stove and the oor
protruding at least 20 cm on the sides and 40
cm at the front.
• Flammable material or material which can
endanger proper operation must not be
placed on the stove or closer to it than the
safety distances.
• It is recommended to keep all objects made
of combustible or ammable materials
such as beams, wooden furniture, curtains,
ammable liquids etc. outside of the stove
irradiation area and, in any case, at least 1 m
from the heating block. (Fig. 8)
• If the exhaust pipe is in contact with a wooden
wall or other ammable material, it must
be insulated with ceramic bre or or other
material having the same features.

Positioning
Minimum aeration for combustion air inlet
Certain measures and prescriptions must
be respected to correctly and safely position
the air inlet (Fig. 9.) They are distances to be
respected to keep combustion air from being
subtracted by another source: for example,
opening a window can suck in outdoor air
makingitinsufcientforthestove.
Make sure that the negative pressure measured
between the installation room and outside is >
4 Pa.

Quality features of the pellets
The pellets, as foreseen by current Italian
legislation governing commodity features
of fuels must be produced exclusively with
untreated wood sawdust without other added
materials.
It is absolutely forbidden to use any solid or
liquid fuel other than pellets to feed the .it.
For best operation of the .it, it is recommended
tousepelletsthequalityofwhichiscertiedby
an authorised body.
The use of poor quality pellets can cause
.it malfunctioning and shall terminate the
warranty.
If the .it remains off for long periods of time,
the tank must be emptied from any residual
fuel.

Operation of the appliance must be veried
with an ignition test in compliance with the
manufacturer installation instructions.
In any case, the functionality of the following
parts must be checked:
-connectiontouegasexhaustsystem;
- external vents;
- electric and hydraulic connections.
• Before lighting the stove, carefully read the
use and maintenance manual.
• Remove all equipment inserted in the tank
when packaged and make sure it is clear of
any foreign bodies.
• Check that the crucible is well inserted in its
seat.
• Unroll the room temperature probe placed
at the back of the stove, moving it to
approximately 20 cm from any hot parts.
• Close the combustion chamber door. Never
open the door when the pellet stove is
operating.
• Connect the stove to a socket using the
supplied cable.
Stove ignition
• Before lighting the stove, make sure that
the brazier is clear of pellets and clean from
residues of previous combustion. Otherwise
empty and clean it.
• Fill the tank up to 3/4 with good quality pellets,
compliant with that described in the standard
UNI EN 14961-2;
• Press the ignition switch at the back of the
stove; the display will read “OFF”;
Ignition
• Press the key for 2 seconds. After a few
seconds, the ue gas extractor fan and the
ignition resistance switch on and the text
“FAN ACC” appears; the igniter LED lights
up.
- After about 1 minute, the text “LOAD WOOD”
appears, the stove loads the pellets and
continues lighting the resistance;
- When the proper temperature is reached, the
display will read “FIRE ON”: this means that
the stove has passed to the last ignition phase
at the end of which it will be fully operational;
the igniter LED switches off.
- After a few minutes, the display will read
“ON1-2-3-4-5” according to the set output,
alternated with the room temperature.
- When the set temperature is reached, the
display will read: “ECO”, alternated with the
room temperature.
- The temperature LED switches on when the
set temperature is reached.
Stove extinction
To switch off the stove, press the key
on
the control panel until the display reads “OFF”.
Evenafterextinctionofthestove,theuegas
extractor fan will continue running for a preset
amount of time to guarantee quick exhaust of
theuegasfromthecombustionchamber.
11
Any solid residues that have been removed and any
parts that have been removed must be disposed of
in accordance with legislation in force.
Whenthemaintenanceoperationsarenished,the
initial connections must be set back up.
You must make sure that the appliance starts up
as required, ensuring that there is no return of the
combustion products during operation.
In case of any irregularities, make sure:
- the air inlets are working correctly
- that the chimney draught is correct
- that the difference in pressure between installation
room and outdoor environment is greater than 4
Pa.
At the end of the check and/or maintenance
operations, the professionally qualied technical
staff will issue an intervention report to the user,
indicating:
- any parts that have been replaced or installed
- any remarks, strong advice and requirements
The user must keep the report safe together with
the documents supplied with the appliance so that
it is available for future consultation.
Maintenance by BTA (Biomass Technical Assistance)
When commissioning the stove, the room
must be well ventilated as unpleasant
smells could develop during the rst
hours of operation due to fumes coming
from paint and grease in the tube and
shell.
ATTENTION!
Ifuegastemperaturereaches220°Cduring
standard operation of the stove (parameter
whichcanbemodiedbythetechnician),the
uegasismodulatedasfollows:
• ue gas exhaust motor set at maximum
speed;
• pellet loading gearmotor at minimum speed;
• tangential heat exchange fan at maximum
speed.
This procedure lowers the temperature of the
uegas.Whenit returnsbelowthethreshold
of 220°C, the stove restores the speed of the
three motors, bringing them back to the prior
setting.
In case of a power failure, when power is
restored, the display indicates the fault status
"Firecool"(amepresent).Suctionwillincrease
toexpeluegasresidue.
Images are purely indicative and may not correspond to the actual product.
They are to be intended as exemplifying to understand operation of the product.
