Page 3: 10-First Start-Up
10-FIRST START-UP 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 first 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 flame.
Page 4: 11-System Requirements
11-SYSTEM REQUIREMENTS 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).
Page 5: 12-First App Start-Up And Association With Mcz Stoves
12-FIRST APP START-UP AND ASSOCIATION WITH MCZ STOVES 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.
Page 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 control are changed, you must have the QR code and passwords available to configure the system.

Page 35 23-SETTINGS MENU Modifying the pellet recipe and air recipe This function is for adapting the stove to the type of pellet in use. In fact, since there are many types of pellets on the market, operation of the stove varies significantly depending on the good or poor quality of the fuel. The amount of pellets in the brazier can be increased or reduced: • If the pellets tend to jam in the brazier due to an excess of fuel • If the flame is increasingly higher even at low power values...

27-SAFETY DEVICES SAFETY DEVICES The product is fitted with the following safety devices. SMOKE TEMPERATURE PROBE It detects the temperature of the smoke, thereby enabling start-up or stopping the product when the smoke temperature drops below the preset value. PELLET HOPPER TEMPERATURE PROBE If the temperature exceeds the preset safety value, it immediately stops the product, which must cool down before the stove is restarted.
Page 45: 28-Alarms
28-ALARMS ALARM SIGNALLING In the event an operating anomaly occurs the stove starts switching off due to the alarm and informs the user of the type of fault that has taken place via a 3 digit code which stays displayed on the rear emergency panel. The alarm is indicated permanently by the relative 3 digit code, by a flashing red LED that lights up on the emergency panel and an intermittent sound signal for the first 10 minutes of the alarm.
Page 46 27-SAFETY DEVICES Faulty gear motor driving sensor (PWM) Contact an authorised service centre. Electronic control unit overheating The structure is too hot because the product has been used for too long at the maximum power or there is poor ventilation. When the stove is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A13.
Page 47 If these causes are excluded, check and if necessary clean the smoke duct and flue (it is recommended for this operation to be carried out by an MCZ qualified technician). The product can be switched on again only after having eliminated the cause permanently.
Page 48 27-SAFETY DEVICES In the event that alarm A21 is triggered often, please note that: Open stove door Close the door Open fuel loading hatch Close the hatch. SAFETY DE- Lower the fuel level in the hopper. VICES TRIP Air pressure switch Draught difficulties or brazier clogged.
Page 49 27-SAFETY DEVICES (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 flue 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.

Page 51: 29-Recommendations For Safe Use
29-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.
Page 52: 30-Cleaning
30-CLEANING EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER Only by properly servicing and cleaning the product is it possible to ensure its safety and correct operation. ATTENTION! All the cleaning operations of all parts must be performed with the product completely cold and the plug disconnected.
Page 53 30-CLEANING REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE SAFE IGNITION AND OPTIMAL OPERATION OF YOUR PELLET PRODUCT. IN CASE OF FAILED IGNITION AND AFTER ANY OTHER BLOCK STATE OF THE PRODUCT, IT IS ESSENTIAL TO EMPTY THE BRAZIER BEFORE EVERY RESTART For the brazier to be cleaned properly, remove it from its housing completely and thoroughly clean all the holes and the grate on the bottom.
Page 54 In the event of breakage it must be replaced. ATTENTION! Never let the stove work without the air filter fitted. MCZ cannot be held liable for any damage caused to the internal components if this requirement is not complied with.
Page 55 30-CLEANING PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN CLEANING THE HEAT EXCHANGER AND THE LOWER COMPARTMENT Half-way through the winter season, but especially at the end, the compartment through which the exhaust smoke passes will need to be cleaned. This cleaning process is mandatory in order to facilitate the general removal of all combustion residue, before it becomes very difficult to remove it due to moisture compacting it over time.
Page 56 30-CLEANING CLEANING THE EXCHANGER CLEANING THE UPPER COMPARTMENT Clean the upper exchanger when the stove is cold and without the cladding in question. After cleaning the lower compartment (see previous paragraph), use a 1 metre long flexible brush to scrape the walls of the firebox (see arrow) to make the ash fall into the lower compartment.
Page 57 30-CLEANING Use a flexible brush to scrape the walls of the firebox (see arrow - respectively to the right and to the left of the firebox) to make the ash fall into the lower compartment. Use a vacuum cleaner nozzle to vacuum up any remaining ash and dust on the exchanger (see arrow). Then thoroughly clean the lower exchanger, replace any gaskets if needed, and reassemble.
Page 58 30-CLEANING CLEANING THE SMOKE EXPULSION SYSTEM AND GENERAL CHECKS Clean the smoke outlet system, especially around the Tee fittings, elbows and any horizontal sections of the smoke duct. For information on periodically cleaning the flue, contact a skilled chimney sweep. Check the seal of the ceramic fibre gaskets on the door of the stove.
Page 59 30-CLEANING PERIODICAL CHECK OF THE DOOR CLOSURE Make sure the door closure ensures a correct sealing action (with the “paper sheet” test) and that when the door is closed, the closing block (X in the figure) does not protrude from the sheet metal to which it is secured. For some products it will be necessary to disassemble the cladding to be able to assess the anomalous protrusion of the block when the door is closed.
Page 60 30-CLEANING SHUTDOWN (end of season) At the end of each season, before switching the product off, it is recommended to remove all the pellets from the hopper with a vacuum cleaner with a long pipe. We recommend removing the unused pellets from the hopper because they can retain moisture. Disconnect any combustion air ducting that can lead to moisture inside the combustion chamber but, above all, ask the specialised technician to refresh the paint inside the combustion chamber with the special silicone spray paints (available at any store or Technical Assistance Centre) during the necessary annual end of season scheduled maintenance operations.
