10-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 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 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.
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”)

4
10-FIRST START-UP
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 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.

NOTES ON USE OF THE TIMER
• The timer always starts the boiler with the last temperature and ventilation settings (or with the default settings at 20°C and V3 if
they have never been altered).
• The start time can be between 00:00 and 23:50
• If the stop time has not yet been saved, the program proposes a start time at +10 minutes.
• If a timer program turns o the stove at 24:00 on one day and another program starts it up at 00:00 on the next day: the stove
remains on.
• A program has a start-up and/or shut-down time that overlap the times of another program: if the stove is already on, the start has
no eect while OFF turns o the stove.
• When the stove is on and the timer is active, pressing the OFF key turns o the stove; the stove then restarts automatically at the
next time of the timer.
• When the stove is o and the timer is active, pressing the ON key turns on the stove; the stove then stops automatically at the next
time of the timer.
SLEEP FUNCTION (main menu)
Sleep may be activated only when the stove is on and allows you to quickly set a time for the product to turn o.
To set the Sleep function, proceed as follows:
• Enter the MENU
• Scroll to the SLEEP item with the <> arrows
• Press Menu
• Set the turn-o time you want using the + and - keys.
The panel shows a default time of 10 minutes after the current time, which can be adjusted with key 6 up to the following day (i.e. the
turn-o can be delayed for a maximum of 23 hours and 50 minutes).
If the SLEEP function is active with theTIMER active, the former has priority, therefore the stove will not turn o at the time set in the timer
program but at the time set by the sleep function, even if it comes after the time set by the timer.

For activation of the“Auto Eco”mode and time settings, see paragraphs 8 f and 8 g respectively.
‘’ECO stop T’’ can be adjusted to ensure correct operation in the various environments in which the stove can be installed and to avoid
constant stopping and starting when the room temperature is subject to sudden change (drafts, poorly insulated rooms, etc.).
The ECO stop procedure is activated automatically when the power recall device is satised (room probe +1°C or external thermostat
with an open contact), the“ECO stopT”starts to decrease the time (factory default 5 minutes, which can be changed from the“Settings”
menu). During this phase, the panel alternates between displaying ON with a small ame and Crono (if active) - Eco active. The minutes
counting down to the Eco Stop are shown at the top of the display. The ame moves to P1 and remains there until the set“T Eco Stop”time
reaches zero, and if the conditions are still satised, turns o the boiler.The ECO stop count is cancelled if one of the devices recalls power.
When the boiler begins to turn o, the panel shows: O - Eco Active - ashing small ame.
When the stove turns o, OFF-ECO appears on the display with the ame symbol o.
The following conditions have to be met simultaneously for the ECO to restart:
• room probe -1°C or external thermostat with a closed contact (for at least 20”in order to prevent false recalls)
• 5 minutes have passed since shut-down.

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.
• 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.

13-SAFETY DEVICES
SAFETY DEVICES
The product is tted with the following safety devices
PRESSURE SWITCH
Monitors pressure in the smoke duct. It is designed to shut down the pellet feed screw in the event of an obstructed ue or signicant
back-pressure (from the wind).
SMOKE TEMPERATURE PROBE
Detects the temperature of the smoke, thereby enabling start-up or stopping the product when the temperature drops below the preset
value.
CONTACT THERMOSTAT IN THE FUEL TANK
If the temperature exceeds the preset safety level, it immediately shuts down the running of the stove.
ELECTRICAL SAFETY
The stove is protected against violent changes in current by a general fuse located in the control panel at the back of the stove. Other fuses
that protect the circuit boards are located on the latter.
SMOKE FAN
If the fan stops, the electronic board shuts o the supply of pellets in good time, and an alarm message is displayed.
GEAR MOTOR
If the reduction motor stops, the stove will continue to run until the ame goes out due to lack of fuel and until a minimum level of cooling
is reached.
TEMPORARY POWER CUT
When a power cut is less than 10’’the stove returns to its previous operating state; if it is more, it executes a cooling/re-ignition cycle.
FAILED START-UP
If during ignition no ame develops, the stove will go into alarm condition.
TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED
If the product is NOT used as described in this instruction manual, the manufacturer declines all liability for any
damage caused to persons and property. The manufacturer furthermore refuses to accept responsibility for damage
to persons and property arising from the failure to observe all the rules contained in the manual and in particular:
• All the necessary measures and/or precautions must be adopted when performing maintenance, cleaning and
repairs.
• Do not tamper with the safety devices.
• Do not remove the safety devices.
• Connect the product to an ecient smoke expulsion system.
• First, check that the environment where it is to be installed is properly ventilated.

13-SAFETY DEVICES
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)

13-SAFETY DEVICES
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).

Attention! The factory setting on the product is designed to obtain the certied technical data. In the event of data
discrepancy (as for the pellet recipe), the settings may be modied as set out above.
The adjustments must only be carried out by authorised and qualied personnel under their responsibility and by
checking the conformity of the installation beforehand.

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.

15-RECOMMENDATIONS FOR SAFE USE
ONLY CORRECT INSTALLATION AND APPROPRIATE MAINTENANCE AND CLEANING OF THE APPLIANCE CAN GUARANTEE
CORRECT OPERATION AND SAFE USE OF THE PRODUCT.
We would like to inform you that we are aware of cases of malfunctioning of domestic pellet-fuelled heating products, mainly due to
incorrect installation and use, as well as inadequate maintenance.
We would like to assure you that all of our products are extremely safe and certied according to European standards of reference. The
ignition system has been tested with the utmost attention to enhance ignition eciency and to prevent any type of problem, even in the
worst operating conditions. In any case, like for any other pellet-fuelled product, our appliances must be installed correctly and undergo
regular periodical cleaning and maintenance to guarantee safe operation. Our studies show us that malfunctioning is mainly due to the
combination of part or all of the following factors:
• Brazier holes obstructed or brazier deformed, due to lack of maintenance and conditions which can cause delayed ignitions,
generating an anomalous production of unburned gases.
• Insucient combustion air due to a reduced or clogged air inlet duct.
• Use of smoke ducts nonconforming to regulatory installation requirements, failing to guarantee an adequate draught.
• Partially clogged chimney, due to lack of maintenance, reducing the draught and making ignition dicult.
• End chimney pot nonconforming to the indications of the instruction manual, and therefore not suitable to prevent potential inverse
draught.
• This factor is crucial when the product is installed in especially windy areas, such as coastal regions.
The combination of one or more of these factors could generate important malfunctioning conditions.
To keep this from occurring, it is fundamental to guarantee that the product is installed in compliance with standards in force.
Furthermore it is of the utmost importance to respect the following simple rules:
• Every time the brazier is removed for cleaning, it must always be put back properly in the work position before using the product,
completely removing any residual lth left on the support base.
• Pellets must never be loaded in the brazier manually, either before ignition or during operation.
• The accumulation of unburned pellets ensuing a failed ignition must be removed before repeating ignition. Also check that they are
fed correctly and that the combustion air inlet/smoke outlet are regular.
• If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation.
Compliance with these indications is absolutely sucient to guarantee proper operation and to avoid any type of problems with the
product.
If the above-mentioned precautions are not taken, and during ignition the brazier is overloaded with pellets thus generating anomalous
smoke in the combustion chamber, carefully follow the indications below:
• Do not disconnect electrical power to the product for any reason whatsoever: this would stop the smoke extractor, releasing smoke
into the environment.
• Take the precaution of opening the windows to ventilate the installation room from any smoke in the environment (the chimney
might not work properly).
• Do not open the re door: this would compromise regular operation of the smoke extraction system to the chimney.
• Just switch the stove o by acting on the on-o button on the control panel (not the rear power supply socket button!) and move
away until smoke has been completely extracted.
• Before attempting re-ignition, clean the brazier and its air passage holes completely of all deposits and unburned pellets. Put
the brazier back in place, removing any residue from its support base. If ignition fails repeatedly, immediately suspend use of the
product and contact a qualied technician to check its operation and the chimney.
