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.
