WARNINGS BEFORE IGNITION
GENERAL WARNINGS
Remove all parts that may burn from the brazier and 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.
CLEAR THE FAILED IGNITION ALARM FROM THE STOVE PANEL OR APP.
REMOVE THE PELLETS LEFT IN THE BRAZIER AND REPEAT IGNITION.
If, after repeated attempts, the ame fails to ignite, despite a regular ow of pellets, check the correct positioning of the brazier, which
must rest snugly against the slots. 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.
Do not touch the stove during the rst start-up, as it is during this phase that the paint sets. If you touch the paint,
you may expose the steel surface.
It is good practice to ensure eective ventilation in the room during the initial start-up, as the stove will emit some
smoke and smell of paint.
If necessary, touch up the paint with the spray can of the specic colour.
Do not stand close to the stove and, as mentioned, air out the room. The smoke and smell of paint will disappear after about an hour of
operation, however, they are not harmful in any case.
The product will be subject to expansion and contraction during the start-up 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.
Upon rst ignition, for the rst pellet hopper, it is recommended to start the stove at maximum power so that the structure and the
smell of the paint settle more quickly.
It is recommended to install the ceramic or serpentine stone cladding after the rst successful ignition.
DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

15-OPERATING MODES
Technical Dept. - All rights reserved - Reproduction prohibited
MAESTRO technology allows the heater to express its utmost potential with even an easier and more intuitive use. A real integrated
micro-computer communicates with your smartphone and further improves the performance of the equipment that continues to work
perfectly even in non-ideal conditions.
It has 5 preset settings making product management even easier, the consumption of the fuel is optimised and improves the comfort of
use, as it can reach extremely quiet operation.
The available settings are:
COMFORT Ideal for all situations requiring maximum comfort. This mode allows an optimised consumption of the fuel to guarantee
a good heating capacity and the best possible silent operation. Once this mode is activated, the user only has to choose the desired
temperature and the appliance will independently manage the ame and ventilation power to ensure maximum comfort. In fact, in this
mode it is not possible to change the power and ventilation, managed intelligently by the MAESTRO system.
AUTO if you prefer traditional automatic operation with the option of setting the temperature and ventilation.
OVERNIGHTGuaranteesthemaximumsilencepossible(noisereduced up to 4 times) allowing the maintenance of the roomtemperature.
This mode is designed, in fact, for night-time operation or temperature conservation in an already pre-heated room ensuring the lowest
possible acoustic impact. In Overnight mode consumption and ventilation are managed intelligently by the MAESTRO system and for this
reason it is not possible to change its values.
MANUAL For those who prefer to use the product in the traditional manner without any temperature control. In this mode the user can
freely choose the mix of ame power and ventilation regardless of consumption or silence.
TURBOOperation at maximum power and ventilation expressed by the product for a limited time (20 min) in order to allow rapid heating
of a cold room. For the expected performance and consumption in this mode, this function can be reactivated only once every hour.

FEED SCREW ACTIVATION (FIRST IGNITION OR AFTER HOPPER EMPTYING)
Prior to rst product ignition, it is necessary to load the fuel and preload the pellets inside the feed screw for loading the fuel in the brazier.
To do this, simply press and hold the key for 10 seconds and the“feed screw
loading”will activate.
The button turns red until the phase ends or is interrupted.
To activate this function, the product must be OFF and COLD (the key
must be white and NOT ashing).
The display shows the feed screw icon and the countdown starting from the
maximum number of seconds provided for the preload cycle (e.g. 120 seconds).
The moment you start to see the pellet drop into the brazier, you
must stop loading by pressing the key.
Ignition must start with an empty brazier and not with a preload.

TURBO MODE
In TURBO mode, the equipment works for the limited time of 20 minutes at its maximum power and ventilation without the possibility
of changing its setting.
Press the key to select the icon.
The icon and the three adjacent dashes light up in red and a
conrmation request appears when selecting the mode. If you
conrm by selecting “ON”, the mode is activated and only the
TURBO indication appears at the centre of the crown.Vice versa,
if you select OFF or if you press the button, you continue
navigating in the direction of the next mode (in this case AUTO).
If activated, all the buttons remain o except and .
In this mode it is not possible to make any adjustment because the equipment emits the maximum of its caloric power.
Every variation requires exiting the mode itself.
The icon is only present if the product is connected to a router; otherwise it is o and the icon is present if Bluetooth has been
enabled.
TheTURBO function has a limited duration of 20 minutes.
Pressing the key allows you to change the mode but only after a double conrmation (see screen
at the side) to prevent an accidental exit. Being a mode that brings the product to maximum speed,
it can only be activated once every hour and accidental exit precludes the possibility of re-entering
the mode for the next 60 minutes.
If, on the other hand, you decide to enter TURBO mode anyway before the 60 minutes expire,
a countdown is shown until the mode can be activated. If you decide to remain in this state even
though the 60 minutes have not expired, the TURBO mode will start working as soon as the
countdown reaches 00:00. Until then the product will work in the last mode.
At the end of the 20 minutes ofTURBO mode, the product will return to the last mode it was in.
If you are “waiting” to enter TURBO mode, double conrmation is not required to change the mode.

FAN BASE ADJUSTMENT
You can use the key to adjust the equipment fan/s.
The rst time you press it allows you to enter the edit screen of the rst fan.
The keys change the fan speed.
Pressing the key repeatedly allows you to choose which fan to modify, from a minimum of 1 to 4
fans, according to the composition/construction of the product.
Once the key has been pressed, it is possible to adjust the power for 4”and if there are no further inputs, it returns to the initial image
with the updated ventilation value or unchanged if there has not been any modication.
EXAMPLE:
1 press of the key
(tangential fan)
2 presses of the key
(if 1 C. AIR fan is present)
3 presses of the key
(if 2 C. AIR fans are present)

20
22 - FANS
The available values start from NO AIR (fan o)/LOW AIR (fan at minimum possible operating speed) up to power 5 (MAXIMUM).
The AUTO mode is added to these choices, which allows self-adjustment of the fan based on the ame power. This mode is very practical
and recommended because this way, the product always generates its maximum heat with minimal noise thanks to parameters that are
tested by the manufacturer.
ATTENTION!
Someproductscancompletelyshutdowntheventilationofone ormorefans thankstotheir conformation andability
to exchange heat. In this case, the NO AIR option will be indicated if you decide to select the minimum ventilation
power. Conversely, some products cannot turn o the fans completely but the minimum power corresponds to a very
slow rotation to facilitate convective motion. In this second case we are referring to LOW AIR.
If one or two fans are set to minimum, the
fan icon changes to and NO AIR or LOW
AIR is indicated according to the product
characteristics and whether the ventilation
can be switched o or not as indicated
above and in the catalogue.
ATTENTION!
If you have a product with more than 1 fan, it is not possible to turn o all the fans manually with the key, but if
you want to make this adjustment, you can enable the SILENT MODE, described below.
