PRECAUTIONS BEFORE START-UP
GENERAL PRECAUTIONS
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.
REMOVE THE PELLETS LEFT IN THE BRAZIER AND REPEAT THE START-UP. (SEE “SAFETY DEVICES/ALARMS” PARAGRAPH)
If after repeated attempts, the ame fails to ignite, despite a regular ow of pellets in 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 boiler 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. (See“Pellet stove accessories”)
It is good practice to ensure eective ventilation in the room during the initial start-up, as the boiler will emit some
smoke and smell of paint.
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 boiler will be subject to expansion and contraction during the lighting and cooling down stages, and may therefore make slight
creaking noises.
This is absolutely normal as the structure is made of laminated steel and must not be considered a defect.
It is extremely important to make sure the boiler does not reach high temperatures straight away, but to increase the temperature
gradually using low power at rst.
This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.
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 a 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.

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.
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 switch o.
