10-FIRST START-UP
Technical Dept. - All rights reserved - Reproduction prohibited
WARNINGS BEFORE START-UP
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 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.
CLEAR THE FAILED IGNITION ALARM FROM THE STOVE PANEL OR APP.
REMOVE THE PELLETS LEFT IN THE BRAZIER AND REPEAT THE IGNITION. (SEE “SAFETY DEVICES/ALARMS” PARAGRAPH)
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 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 absolutely normal as the structure is made of laminated steel and must not
be considered a defect.
Upon rst ignition, for the rst pellet tank, 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!!!

11-SYSTEM REQUIREMENTS
APP
The MCZ Maestro App is already available on the“Handheld remote control”accessory or will be available in various playstores.
STOVE
Equipped with MAESTRO system
OPERATION
For the utmost versatility of use, two Wi-Fi modules have been designed, supporting priority connection with your smartphone and/or
handheld remote control (optional).
The stove’s operation status, room temperature, operating parameters (such as ventilation, power, etc.) and any alarms may be checked
remotely.
Attention!
The App is already available in English on the “Handheld remote control” accessory as the language used on the
telephone is set by default. If the App is downloaded onto a personal smartphone, it similarly adopts the language
already in use on the phone. In either case, it is possible to open the “LANGUAGE” screen in the app and select the
desired language.

12-FIRST APP START-UP AND ASSOCIATION WITH MCZ STOVES
Technical Dept. - All rights reserved - Reproduction prohibited
The app lets you communicate with MCZ stoves using two technologies:
• home Wi-Fi
• remote Wi-Fi
HOME WI-FI
Point-to-point connection between the telephone and the stove, to communicate with the stove without relying on routers or internet
connections. This is possible when the telephone and stove are located nearby (we recommend max 5 metres). The range of action
depends on the characteristics of the walls and the conformation of the home.
REMOTE WI-FI
Connection between the app and stove using an internet connection. With this technology you can communicate with the stove from
anywhere. Near the stove there must be a Wi-Fi router providing an internet connection and the mobile phone in turn must have data
connection.
The rst time you start the app without having congured any devices, the app opens displaying the“device list”screen.
There are two ways to associate MCZ devices:
• automatically
• manually

6
12-FIRST APP START-UP AND ASSOCIATION WITH MCZ STOVES
IMPORTANT!! Do not lose or remove the QR code from the stove. If the stove is reset and/or the smartphone and/or
handheld remote controlare changed, you must have the QR code and passwords available to congure the system.
AUTOMATIC MODE
The QR code and the passwords are located at the back of the stove and in the warranty.
Scan the QR code using the camera of the device (accessory or smartphone) and acquire it.
When the code is acknowledged, the app will ask you to enter an identication number for the stove (for example“living room stove”) to
easily identify the stove/s in the list of congured devices.
This will automatically congure the app to work with both homeWI-FI and remoteWI-FI technology.

14-COMFORT SET
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 performances of the heater that continues to perfectly work
even in non-ideal conditions.
The new App has 5 preset sets with which the management of the stove is even easier, the consumption of the fuel is optimized and
improves the comfort of use, as it can reach an extremely quiet operation.
The available set are:
COMFORT Ideal for all situations requiring maximum comfort. In this mode the stove allows an optimized 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.
DYNAMIC If you prefer traditional automatic operation with the option of setting the temperature and ventilation.
OVERNIGHTGuaranteesthe maximum silence possible (noise reducedup to 4 times) allowingthemaintenanceof 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 way without any temperature control. In this mode the user can
choose at will the mix of ame power and ventilation regardless of consumption or silence.
POWER Operation at maximum power expressed by the product for a limited time (20 min) in order to allow rapid heating of a cold
environment. For the performance and consumption expected in this mode, this function can be reactivated only once every hour.

the residual heat in the structure being disposed of.
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 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
