WARNINGS BEFORE IGNITION
GENERAL WARNINGS
Remove any objects that may burn from the product brazier and from the glass (manual, various adhesive labels or any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
The rst ignition may not be successful as the feed screw is empty and does not always manage to load the brazier
with the required amount of pellets in time to light the ame.
CANCEL THE FAILED IGNITION ALARM BY PRESSING AND HOLDING THE ON/OFF KEY FOR A FEW SECONDS. REMOVE THE
PELLETS LEFT IN THE BRAZIER AND REPEAT IGNITION.
SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP
First connect the power cable to the back of the stove and then to a wall socket.
To switch the stove on and o, press the button 1on the control panel or press the button 3from the remote control (optional accessory).
The display on the panel will be ON with a ashing ame. When the ame stops blinking, the stove has reached the operating condition
to“supply power”.
The default factory set room temperature is 20°C. To change this setting, follow the instructions in the adjustments menu. Do the same
to set the heating water temperature and the speed of the room fan (if required). To activate an external thermostat, if present, see the
dedicated paragraph.

11-FIRST START-UP
SETTING THE TYPE OF INSTALLATION WHEN STARTING THE PRODUCT FOR THE FIRST TIME
The installation of the product and the type of installation must only be carried out by a qualied operator.
The rst time the stove is switched on, the PRODUCT TYPE screen appears.
After choosing the PRODUCT TYPE, the INSTALLATIONTYPE screen appears.
On this screen, you can choose the installation with a single wall MONO ue or a double wall COAX ue.
The MONO type of single wall installation applies to both the rear and upper smoke outlet, whereas the COAX double wall is only valid for
the XUP installation (see chapter 5, SMOKE OUTLET).
After selecting the type of installation, the screen returns to HOME, and it will no longer be possible to see the PRODUCT TYPE screen at
the rst start-up.
It is, however, possible to change the type of installation by accessing the“TECHNICAL MENU”(a password is required and, therefore, the
intervention of an AUTHORISEDTECHNICIAN).

11-FIRST START-UP
Technical Dept. - All rights reserved - Reproduction prohibited
SWITCHING THE EQUIPMENT OFF
To switch o the appliance, press the button 1 on the emergency panel or the button 3 on the optional remote control.
The equipment will start the shutdown process which involves consuming the residual pellets in the brazier, the latter being cleaned and
the residual heat in the structure being dissipated.
During the residual heat dissipation phase, the fans operate at about 80% of their output and the speed cannot be varied. This is
determined by the need for all the accumulated heat to be evacuated safely and quickly. The shutdown stage can last 15 - 30 minutes
depending on the heat stored in the structure, determined by the duration and the operating speed of the product throughout the day.
When the internal temperature drops below the set thresholds, the fans for hot air and exhaust smoke extraction will automatically
switch o.
POWER SUPPLY
When ignition is complete, the panel will display ON with a steady ame at level 3 . The following ame modulation for higher or
lower power is then controlled autonomously based on reaching the set temperature.
(also see“OPERATING MODE”-“Set Flame”)
If the ame fails to ignite, despite a regular ow of pellets, check that the brazier is seated correctly: it must rest snugly against the
interlocking slot and be clean of any ash incrustations. If no anomaly is found during this inspection, there may be a problem with
the product components or installation may not be correct.
REMOVE THE PELLETS FROM THE BRAZIER AND CONTACT AN AUTHORISED TECHNICIAN.
Please ensure the brazier is clear of ALL pellets and ash build up following any failed ignitions. Failure to clear out
the brazier prior to resetting may result in further failed ignitions or explosive ignition under certain conditions.
It is good practice to ensure eective ventilation in the room during the initial ignition, as the product will emit some
smoke and smell of paint.
Do not stand close to the product and ventilate the room as mentioned.The smell of paint will disappear after about an hour of operation,
however, it is not harmful in any case.
The product will be subject to expansion and contraction during the ignition and cooling stages, therefore slight creaking noises may be
heard.
This is perfectly normal as the structure is made of laminated steel and must not be considered a defect.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!! THE PRODUCT NEEDS SOME RUNNING-IN TIME.
It is extremely important to make sure the product does not reach high temperatures straight away, but to increase the temperature
gradually using low power at rst.
This will prevent damage to the welds and to the steel structure.
Do not touch the product during the rst lighting, as it is during this stage that the paint sets. If you touch the paint,
you may expose the steel surface.
If required, touch up the paint with the spray can of the specic colour.

h - Pellet Recipe
This function is for adapting the stove to the type of pellet in use. As there are many types of pellets available on the market, operation
of the stove can vary considerably according to the quality of the fuel. When the pellets clog up the brazier due to excess loading of fuel
or when the ame is always high even at low power, or when the ame is low, it is possible to decrease/increase the amount of pellets
in the brazier:
The available values are:
-3 = A decrease of 20% with respect to the factory setting.
-2 = A decrease of 13% with respect to the factory setting.
-1 = A decrease of 6% with respect to the factory setting.
0% No changes.
3 = An increase of 10% with respect to the factory setting.
2 = An increase of 6% with respect to the factory setting.
1 = An increase of 3% with respect to the factory setting.
Proceed as follows to edit the recipe:
• Press the“menu”key.
• Use the arrow keys to scroll through and select“Settings”
• Press“menu”to conrm.
• Scroll with the arrows and select “Pellet recipe’’.
• Press“menu”to conrm.
• Edit the % by using the + - keys.
• Press‘’menu’’to conrm and‘’esc’’to exit
i - Smoke rpm % variation
In the event the installation presents problems in extracting smoke (lack of draught or even pressure in the duct), it is possible to increase
the smoke and ash extraction speed. This change resolves all potential problems related to pellets clogged in the brazier and deposits
forming at the bottom of the brazier itself caused by poor quality fuel or fuel that produces a lot of ash. The values available range from
-30% to +50%, with increments of 10 percent at a time. Negative variation may be required if the ame is too low.
To edit this parameter, proceed as follows:

NORMAL SHUTDOWN (on the panel: OFF with ashing ame)
When the shutdown key is pressed, or when there is an alarm signal, the stove enters the thermal extinguishing stage which involves
automatic execution of the following stages:
• Pellet loading stop
• The room fan maintains the set speed until reaching the shutdown temperature
• The smoke extractor fan is activated at maximum speed and remains on for a xed period of 10 minutes, at the end of which if the
smokeT has dropped below the shutdown threshold, the fan stops, otherwise it will continue to operate at minimum speed until the
temperature drops below the threshold and then turn o.
• If the stove has been shut down regularly but, due to thermal inertia, the smoke temperature exceeds the threshold again, the
shutdown stage will be repeated at minimum speed until the temperature drops.
BLACKOUT WITH STOVE ON
In the event of a blackout, the stove acts as follows:
• Blackout less than 10”: resumes operation;
• After a power outage of more than 10’’which occurred when the stove was on, or during ignition, when the stove is powered again
it returns to its previous operating condition as follows:
1. Cools the boiler by activating the smoke extractor at minimum speed for 10’then proceeds to the next step;
2. Restores the stove to the operating condition prior to the blackout.
During stage 1, the panel shows ON BLACK OUT.
During stage 2, the panel shows Ignition.
If during stage 1 the stove receives manual user commands from the control panel, it stops the blackout reset sequence and begins the
start-up or shutdown as requested by the user.
BLACKOUT OF MORE THAN 10’’DURING STOVE SHUTDOWN
If the stove experiences a loss of power LONGER THAN 10” while it is shutting down, when power is restored to the stove, it will
automatically turn on in shutdown mode, even if the smoke temperature has fallen below 45°C in the meantime. This last stage can be
skipped by pressing key 1 (esc) (skips to start-up) and pressing it again (recognises that the stove is o).
BLACKOUT OF MORE THAN 10’’WITH THE STOVE OFF FOR ECOSTOP
Once power has been restored, a 5-minute timer is set as though the stove were in shutdown mode. Should there be a request for heat in
these 5 minutes, the stove will not start.
SAFETY DEVICES ALARM A05
The safety devices alarm includes operation of the smoke pressure switch, of the fuel loading hatch and of the open stove door.
The alarm will be triggered after 30 seconds, after which the stove will stop working (e.g. after 30 seconds with the pellet loading
hatch open, alarm A05 will be triggered).

Series of stoves equipped with a pressure switch installed on the hopper with the sampling point positioned on the bottom, to the right of
the gear motor. This system protects the whole system ensuring tightness of the stove throughout its duration.
It is important to understand that the pressure switch can be triggered with each signicant drop in negative pressure and may be due to:
• Flue clogging.
• The presence of a foreign body in the ue (birds, nests, clogged grilles, etc.).
• Wind coming through the ue because it is unprotected or the installation was wall-mounted or required no ue.
• Cold air draught down the ue.
• A damaged pressure switch.
• Blocked membrane inside the pressure switch because soot or pellet dust got in.
• The pellet hopper is open or ajar for more than 60 seconds (60 seconds is the estimated time to reload the hopper).
• Pellets trapped between the hopper cover and the hopper, which prevents the gasket from sealing.
• Broken/worn hopper cover gasket.
• The gasket between the feed screw and the boiler is damaged or positioned incorrectly.
• Fire door is open or the gasket is worn.
• Clogged lateral smoke exchangers.
• Inspection caps with gaskets installed incorrectly after maintenance.
• Feed screw clogged by compressed pellets at the top.
• The installation is compliant and the ue/smoke tting does not generate obvious obstructions which can stop the release of smoke,
such as: long horizontal sections (over 3 metres), uninsulated smoke ducts,“wall-mounted”smoke exhaust without proper terminals
(installation regulated and permitted in France only [ZONE 3])
• Internal air extraction or recirculation systems (e.g. VMC systems) that generate internal negative pressure exceeding the value
required by law (not exceeding 4 Pa)
• Installed without combustion air ducting, it is crucial to check that there is an ecient air inlet dedicated to the stove, according to
the specications referred to in chapter 2 of this manual.
The circuit board has also been equipped with an automatic device with a timer and contactors which increase the RPM of the smoke
extractor so as to restore the negative pressure inside the hopper and therefore the pressure switch, if the cover is opened for top-up or if
there is an immediate or occasional pressure drop such as gusts of wind outside. If the pressure drop lasts for more than 60 seconds, the
product goes into alarm status (A05 or A18)

Remembering that the draught recommended for the products to work properly is 10 Pa at maximum capacity and 5 Pa at minimum
(according to the technical data sheet found in the user and maintenance manual), adjustments may be required in worse draught
conditions (also due to the position of the ue in areas that are particularly subject to adverse weather such as prevailing winds, snow,
northern exposure, etc.) so as to always guarantee the required negative pressure inside the hopper.
To compensate for the lack of internal negative pressure simply adjust the speed (RPM) of the smoke extractor so as to guarantee the
minimum values of the table.
If the negative internal pressure values are noted to be lower than those indicated, this can also be due to the internal gaskets not being
sealed properly or to the product being worn over time.
OPERATING INSTRUCTIONS ON NEGATIVE PRESSURE INSPECTIONS AND POSSIBLE VARIATIONS OF THE RPM
Connect a pressure gauge to the pressure outlet on the hopper:
• For products with a specic pressure outlet in the hopper, access the sampling point and connect the pressure gauge
• For products without a dedicated pressure outlet, disconnect the tube of the pressure switch from the pressure outlet on the hopper,
add a “Tee”on the tube to intercept the circuit connecting the pressure gauge and reconnect the tube to the pressure outlet on the
hopper.
Possible adjustments of combustion and consequently of the negative pressure inside the hopper can be implemented in two ways:
A) Changing the RPM value of the smoke extractor in the SETTINGS MENU
• The available values are from -3 to +3 which, as a percentage, correspond to:
• RPM: -10% +10% in Active System products
• RPM: -30% +50% in NON-Active System products
• The percentage variation aects all power values (1 to 5) proportionally and as a percentage.The percentage variation does not aect
intermediate operating stages such as SWITCH ON, FIRE ON or SWITCH OFF
• As the RPM increases, suction also increases and consequently the internal negative pressure, thereby compensating the phenomena
that trigger the alarm.
B) Adjusting the RPM of the gear motor manually in theTECHNICAL PARAMETERS MENU
• The pressure switch has a calibration of 10/20 Pa which means that it trips when the negative pressure inside the hopper drops below
10 Pa and requires more than 20 Pa negative pressure inside the hopper for it to reset
• The negative pressure value at the minimum power must always be higher than 10 Pa while also maintaining a reasonable margin
that can worsen over time due to the gaskets or similar being worn (at least 12/13 Pa)
• The negative pressure at maximum power must always be above 20 so that the pressure switch can reset when the pressure switch
resetting automated device is activated. The pressure switch resetting procedure (such as after opening the cover to top-up the
hopper), requires the electronics to push the RPM of the smoke extraction fan up to POWER 5 (P5) for a few moments. At P5,
therefore, the negative pressure inside the hopper must always be > 20 Pa (recommended 22/23 Pa to preserve the margin).
