13-FIRST START-UP
Technical Dept. - All rights reserved - Reproduction prohibited
PRECAUTIONS BEFORE START-UP
GENERAL PRECAUTIONS
Remove any objects that may burn from the brazier (manual, various adhesive labels or any polystyrene).
Check that the brazier is positioned correctly and rests properly on the base.
The rst start-up may not be successful as the feed screw is empty and does not always manage to load 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
PELLET LEFT IN THE BRAZIER AND REPEAT THE START-UP.
SETTINGS TO BE CARRIED OUT BEFORE THE INITIAL START-UP
After connecting the power cable to the back of the product, turn the switch at the back to position(I). To turn the stove on or o, press
button 1on the control panel.
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 target room temperature is set at 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 ventilation fan (if provided).To activate an external thermostat, if present, see
the dedicated paragraph.
SWITCHING THE EQUIPMENT OFF
To switch the equipment o, press and hold the ON-OFF button on the remote control or on the APP. The acoustic beep conrms this phase
has started.
Alternatively, switch it o from the emergency panel by following the instructions provided in the dedicated chapter
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 disposed of.

4
13-FIRST START-UP
During the disposal phase of the residual heat, 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 switch-o phase can last 15 - 30 minutes
depending on the heat stored in the structure, determined by the duration and the operating regime of the product throughout the day.
When the internal temperature drops below the set thresholds, the fans for hot air and exhaust fume extraction will automatically switch
o.
POWER SUPPLY
When start-up is complete, the panel will display ON with a constant ame at level 3 . The modulation of the ame for higher or
lower power is then controlled autonomously on the basis of reaching the set temperature.
(see also“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 free from 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 in certain conditions an explosive ignition.
It is good practice to ensure eective ventilation in the room during the initial start-up, as the product will emit
some smoke and smell of paint.
Do not stand close to the boiler and ventilate the room as described. 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 start-up and cooling phases, therefore slight creaking noises may
be heard.
This is absolutely 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 the steel structure.
Do not touch the product during the rst lighting, as it is during this phase that the paint sets. If you touch the paint,
you may expose the steel surface.
If necessary, 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 pellet 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 ames are high even at low power, or when the ames are low, it is possible to decrease/increase the amount of pellets in the
brazier:
Available values:
-3 = A decrease of 20% on the factory setting.
-2 = A decrease of 13% on the factory setting.
-1 = A decrease of 6% on the factory setting.
0% No changes.
3 = An increase of 10% on the factory setting.
2 = An increase of 6% on the factory setting.
1 = An increase of 3% on the factory setting.
Edit the recipe as follows:
• 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.
• Alter the % with the + - keys.
• Press‘’menu’’to conrm and‘’esc’’to exit.
i - Variation % rpm smoke
In the event the installation presents problems in extracting smoke (lack of draft or even pressure in the duct), it is possible to increase
the smoke and ash extraction speed.This change resolves all the potential problems related to pellets clogging 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 extraction speed may be
altered between -30% to +50%, with increments of 10 percent at a time. Negative variation can be necessary if the ame is too low.
To alter this parameter, proceed as follows:
• Press the“menu”key.
• Use the arrow keys to scroll through and select“Settings”
• Press“menu”to conrm.

NORMAL SHUTDOWN (on the panel: OFF with ashing ame symbol)
When the shutdown key is pressed, or when there is an alarm signal, the stove enters the thermal extinguishing phase which involves
automatic execution of the following phases.
• Stop pellet loading
• The room fan maintains the set speed until reaching the switch-o 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
smoke T has dropped below the stop threshold, the fan stops, otherwise it will continue to operate at minimum speed until the
temperature drops below the threshold.
• If the stove has been shutdown regularly but, due to thermal inertia, the smoke temperature exceeds the threshold again, the
shutdown phase will be repeated at minimum speed until the temperature drops.
BLACKOUT WITH STOVE ON
In the event of a blackout, the stove does the following:
• Power failure of less than 10”: continues the work in progress;
• After a loss of power of more than 10’’ which occurred when the stove was on, or during ignition, you can restore the stove to its
previous operating condition when power returns as follows:
1. Cool the boiler by activating the smoke extractor at minimum speed for 10’then proceed to the next step;
2. Restore the stove to the operating condition prior to the blackout.
During phase 1, the panel shows ON BLACK OUT.
During phase 2, the panel shows Start-up.
If during phase 1 the stove receives manual user commands from the control panel, it stops the blackout restoration sequence and begins
the start-up or shutdown commanded by the user.
BLACKOUT OF MORE THAN 10’’ DURING EXTINCTION OF STOVE
If the stove experiences a loss of power GREATER 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 phase 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 FROM ECOSTOP
Once power has been restored, a 5-minute timer is set as though the stove were in switch-o 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 the intervention 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 intervene with each signicant drop in negative pressure and may be due to:
• The ue clogging.
• The presence of a foreign body in the ue (birds, nests, clogged grates, 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 ltrated.
• The pellet hopper is open or ajar for more than 60 seconds (60 seconds is the estimated time to reload the hopper).
• Pellet trapped between the hopper cover and the hopper, which prevents the gasket to seal.
• 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 a compressed pellet 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 those 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 electronic board has also been equipped with an automatic device with a timer and contactors which increases 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 is set in an alarm statue (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 tabular values.
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 by 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:
• In the case of products with a specic pressure outlet in the hopper, access the sampling point and connect the pressure gauge
• In the case of products without a dedicated pressure outlet, disconnect the tube of the pressure switch from the pressure outlet on
the hopper, add a“T”on the tube to intercept the circuit, connecting the gauge and reconnect the tube to the pressure outlet on the
hopper.
Possible adjustments of the combustion and consequently of the negative pressure inside the hopper can be implemented in two ways:
A) Change 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 the 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 increase, 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 disarms 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 rearm
• The negative pressure value at the minimum power must always be higher than 10 Pa while also maintaining a reasonable margin
that can be used over time due to the gaskets being worn or something similar (at least 12/13 Pa)
• The negative pressure at maximum power must always be above 20 so that the pressure switch can rearm when the pressure
switch rearming automated device is activated. The pressure switch rearming 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).

Changing the smoke fan revolutions
In the event the installation presents problems in extracting smoke (lack of draft or even pressure in the duct), it is possible to increase
the smoke and ash extraction speed.This change resolves all the potential problems related to pellets clogging 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 extraction speed may be
altered between -30% to +50%, with increments of 10 percent at a time. Negative variation can be necessary if the ame is too low.
To alter this parameter, proceed as follows:
• 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“Fumes rpmVar.”
• Press“menu”to conrm.
• Alter the % with the + - keys.
• Press‘’menu’’to conrm and‘’esc’’to exit.
