10-FIRST START-UP

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 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

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

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 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 home WI-FI and remote WI-FI technology.

EXAMPLE OF QR AND PASSWORD LABEL

12-FIRST APP START-UP AND ASSOCIATION WITH MCZ STOVES

MANUAL MODE

The QR code and the passwords are located at the back of the stove and in the warranty. In this case, the codes must be used.

If the stove cannot be congured using the QR code, it can be done using the DIRECT or REMOTE key.

To congure operation in HOME WI-FI mode, click on the “DIRECT” key and the “select device” screen opens. The stoves nearby are scanned;

select your stove and enter the password (located near the QR code at the top) and a stove identication name (for example “living room

stove”) to easily identify the stove/s in the list of congured devices.

To congure operation in REMOTE WI-FI mode, click on the “REMOTE” key and the “SELECT DEVICE” screen opens. Fill in all the elds with

the codes on the label (near the QR code at the bottom) and a stove identication name (for example “living room stove”) to easily identify

the stove/s in the list of congured devices

13-STOVE ACCESSORY CONFIGURATION

Once the app has been congured, you can communicate with the stove in Home mode and also congure stove accessories from the app:

• REMOTE WI-FI module (if any)

• WI-FI temperature probe (not supplied)

In order to congure the accessories, the mobile phone must be near the accessories.

CONFIGURATION OF REMOTE WI-FI MODULE FROM MCZ MAESTRO APP

To do this connect to the stove in home mode through the app. From the “settings” / “basic settings” menu, select the congure accessories

item: if there are still accessories to be congured, the two keys can be selected.

click congure remote ------ a screen opens, displaying nearby Wi-Fi routers. Select the router providing internet connection and enter

the respective password. From now on, if the router provides a stable internet connection, it is possible to command the stove remotely.

The access password to the network by the Maestro App must have a maximum of 32 characters. For longer

passwords, for example generated automatically by the router upon initial installation, the length must be modied

according to the procedures for your router.

Additional functions

Once the remote stove Wi-Fi module has been connected to the home router, every time the router is available, the remote stove Wi-Fi

module will reconnect automatically.

If the router is replaced or the password is changed, the remote stove Wi-Fi module will revert to conguration mode as it can no longer

connect.

The WI-FI modules have an auto-reset mechanism.

13-STOVE ACCESSORY CONFIGURATION

CONFIGURATION OF WI-FI TEMPERATURE PROBE FROM MCZ MAESTRO APP

The Wi-Fi temperature probe (ACCESSORY) is supplied without batteries. From when the batteries are inserted, the probe can be congured

within the next 8 minutes. Therefore insert the three AA batteries shortly before you are ready to proceed with the conguration.

Then:

• insert two batteries immediately, then insert the third after placing the sensor next to the WiFi emergency panel (approximately 2

cm)

• wait for the beep-beep indicating that pairing has successfully occurred (it must occur within 10”)

• connect to the stove through the app in home mode

• access the settings - basic settings - accessories menu selecting the congure accessories item

If the Wi-Fi temperature probe is available for conguration, the key can be selected, while if the key stays disabled check that the probe

batteries are charged, or check that the maximum available time has not elapsed.

In this case, remove the batteries and put them back in, or press the reset button by inserting a paper clip in the hole to the right of the

sensor dome. From this time on, the 8 minutes for conguration restart.

If the probe is ready for conguration click the key in the app screen, click T° probe conguration ------ the screen will show the stoves

with which the Wi-Fi probe can be associated; select your stove and enter the home Wi-Fi password (see QR code label).

Once the Wi-Fi probe is connected, you can congure the stove to use the remote sensor; to do this use the shortcut by clicking on the

temperature indicator at the top right of the app screen and select the “Wi-Fi probe” as the temperature input. Or from the setup menu

choose to congure ambient input and select the “Wi-Fi probe” temperature input.

Should it be necessary to reset the WiFi probe, because already coupled to another device or congured incorrectly,

use two paper clips. With the rst one, press and hold the key below the bottom left hole and with the other one,

press the key below the right hole once.

Repeat the conguration procedure indicated at the start of the page.

TEMPERATURE SENSOR

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.

OVERNIGHTGuarantees the maximum silence possible (noise reduced up to 4 times) allowing the maintenance of the room temperature.

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.

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.

SAFETY DEVICES

The product is tted 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.

ELECTRICAL SAFETY

The product is protected against power surges by a general fuse located in the control panel on the back. Other fuses that protect the

circuit boards are located on the latter.

SMOKE FAN BREAKAGE

If the fan stops, the circuit board promptly blocks the supply of pellets and the alarm is displayed.

GEAR MOTOR BREAKAGE

If the gear motor stops, the product switches o and the relative alarm is signalled.

TEMPORARY POWER CUT

If a power cut occurs during operation, the product automatically sets itself in cooling mode when the power is restored and then it

restarts.

FAILED IGNITION

If no ame lights during start-up, the product will go into alarm conditions.

IT IS FORBIDDEN TO TAMPER WITH THE SAFETY DEVICES.

It is possible to relight the product and therefore restore the automatic operation of the probe only after having eliminated the cause of

the intervention of the safety system. This manual will help you understand which anomaly has occurred, and explain how to intervene

according to the alarm message displayed on the appliance.

28-ALARMS

ALARM SIGNALLING

In the event an operating anomaly occurs the stove starts switching o due to the alarm. The type of alarm appears on the App. The app

signals the active alarm codes while a red LED lights up on the stove panel.

Exiting the alarm conditions

Follow the procedure described below to restore normal stove operation after an alarm has been triggered:

• Cancel alarms A01, A02, A03, A05, A21 only from the panel on the stove.

• Cancel the other alarms from the App.

Mechanical stove block

The following conditions may cause the mechanical stove block:

• Structure overheating (“A03”)

• Smoke overheating (“A04”)

• During stove operation air has entered the combustion chamber or there is an obstruction in the ue (“A05”)

Only alarm A21 emits an intermittent beep as long as the alarm is active. In this situation, the automatic shut-down sequence is activated.

When this sequence is initiated, any attempt to restart the system will be ineective. The display signals the cause of the blockage.

SOLUTIONS:

If “A03” appears: 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 cools down suciently, clear alarm A03 on the stove panel. Once the alarm is cancelled, the product can be switched on

normally.

If “A04” appears: The stove switches o automatically. Let the stove cool down for a few minutes and then switch it on again. Check the

smoke expulsion and verify the type of pellet used according to the instructions found in the specic chapter of the manual.

If “A05” appears: the door has been left open for too long or a signicant amount of air has entered (e.g. missing smoke fan inspection

cap). If these causes are excluded, check and if necessary clean the smoke duct and ue (it is recommended for this operation to be carried

out by an MCZ qualied technician).

The product can be switched on again only after having eliminated the cause permanently.

Series of stoves equipped with a pressure switch installed on the hopper with the sampling point positioned on the bottom, to the right of

the gear motor. This system protects the whole system ensuring tightness of the stove throughout its duration.

It is important to understand that the pressure switch can be triggered with each signicant drop in negative pressure and may be due to:

• Flue clogging.

• The presence of a foreign body in the ue (birds, nests, clogged grates, etc.).

• Wind coming through the ue because it is unprotected or the installation was wall-mounted or required no ue.

• Cold air draught down the ue.

• A damaged pressure switch.

• Blocked membrane inside the pressure switch because soot or pellet dust ltrated.

• The pellet hopper is open or ajar for more than 60 seconds (60 seconds is the estimated time to reload the hopper).

• Pellet trapped between the hopper cover and the hopper, which prevents the gasket to seal.

• Broken/worn hopper cover gasket.

• The gasket between the feed screw and the boiler is damaged or positioned incorrectly.

• Fire door is open or the gasket is worn.

• Clogged lateral smoke exchangers.

• Inspection caps with gaskets installed incorrectly after maintenance.

• Feed screw clogged by compressed pellets at the top.

• The installation is compliant and the ue/smoke tting does not generate obvious obstructions which can stop the release of smoke,

such as: long horizontal sections (over 3 metres), uninsulated smoke ducts, “wall-mounted” smoke exhaust without proper terminals

(installation regulated and permitted in France only [ZONE 3])

• Internal air extraction or recirculation systems (e.g. VMC systems) that generate internal negative pressure exceeding that required

by law (not exceeding 4 Pa)

• Installed without combustion air ducting, it is crucial to check that there is an ecient air inlet dedicated to the stove, according to

the specications referred to in chapter 2 of this manual.

The circuit board has also been equipped with an automatic device with a timer and contactors which increase the RPM of the smoke

extractor so as to restore the negative pressure inside the hopper and therefore the pressure switch, if the cover is opened for top-up or if

there is an immediate or occasional pressure drop such as gusts of wind outside. If the pressure drop lasts for more than 60 seconds, the

product is set in an alarm status (A05 or A18)

•

28-ALARMS

Remembering that the draught recommended for the products to work properly is 10 Pa at maximum capacity and 5 Pa at minimum

(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 ue 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.

To compensate for the lack of internal negative pressure simply adjust the speed (RPM) of the smoke extractor so as to guarantee the

minimum tabular values.

If the negative internal pressure values are noted to be lower than those indicated, this can also be due to the internal gaskets not being

sealed properly or to the product being worn over time.

OPERATING INSTRUCTIONS ON NEGATIVE PRESSURE INSPECTIONS AND POSSIBLE VARIATIONS OF THE RPM

Connect a pressure gauge to the pressure outlet on the hopper:

• In the case of products with a specic pressure outlet in the hopper, access the sampling point and connect the pressure gauge

• In the case of products without a dedicated pressure outlet, disconnect the tube of the pressure switch from the pressure outlet on

the hopper, add a “Tee” on the tube to intercept the circuit connecting the pressure gauge and reconnect the tube to the pressure

outlet on the hopper.

Possible adjustments of the combustion and consequently of the negative pressure inside the hopper can be implemented in two ways:

A) Change the RPM value of the smoke extractor in the SETTINGS MENU

• The available values are from -3 to +3 which, as a percentage, correspond to:

• RPM: -10% +10% in Active System products

• RPM: -30% +50% in NON-Active System products

• The percentage variation aects all power values (1 to 5) proportionally and as a percentage. The percentage variation does not aect

intermediate operating stages such as SWITCH ON, FIRE ON or SWITCH OFF

• As the RPM increases, suction also increases and consequently the internal negative pressure, thereby compensating the phenomena

that trigger the alarm.

B) Adjusting the RPM of the gear motor manually in the TECHNICAL PARAMETERS MENU

• The pressure switch has a calibration of 10/20 Pa which means that it disarms when the negative pressure inside the hopper drops

below 10 Pa and requires more than 20 Pa negative pressure inside the hopper for it to rearm

• The negative pressure value at the minimum power must always be higher than 10 Pa while also maintaining a reasonable margin

that can be used over time due to the gaskets being worn or something similar (at least 12/13 Pa)

• The negative pressure at maximum power must always be above 20 so that the pressure switch can rearm when the pressure

switch rearming automated device is activated. The pressure switch rearming procedure (such as after opening the cover to top-up

the hopper), requires the electronics to push the RPM of the smoke extraction fan up to POWER 5 (P5) for a few moments. At P5,

therefore, the negative pressure inside the hopper must always be > 20 Pa (recommended 22/23 Pa to preserve the margin).

• N.B. = The TECHNICAL PARAMETERS menus are password-protected to prevent the user from accessing them

inadvertently

Attention! The factory setting on the product is designed to obtain the certied technical data. In the event of data

discrepancy (as for the pellet recipe), the settings may be modied as set out above.

The adjustments must only be carried out by authorised and qualied personnel under their responsibility and by

checking the conformity of the installation beforehand.

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.

We would like to assure you that all of our products are extremely safe and certied according to European standards of reference. The

ignition system has been tested with the utmost attention to enhance ignition eciency and to prevent any type of problem, even in the

worst operating conditions. In any case, like for any other pellet-fuelled product, our appliances must be installed correctly and undergo

regular periodical cleaning and maintenance to guarantee safe operation. Our studies show us that malfunctioning is mainly due to the

combination of part or all of the following factors:

• Brazier holes obstructed or brazier deformed, due to lack of maintenance and conditions which can cause delayed ignitions,

generating an anomalous production of unburnt gases.

• Insucient combustion air due to a reduced or clogged air inlet duct.

• Use of smoke ducts nonconforming to regulatory installation requirements, failing to guarantee an adequate draught.

• Partially clogged chimney, due to lack of maintenance, reducing the draught and making ignition dicult.

• End chimneypot not conforming to the indications of the instruction manual, and therefore not suitable to prevent potential inverse

draught.

• This factor is crucial when the product is installed in especially windy areas, such as coastal regions.

The combination of one or more of these factors may generate severe malfunctioning conditions.

To keep this from occurring, it is crucial to guarantee that the product is installed in compliance with standards in force.

Furthermore it is of the utmost importance to comply with the following simple rules:

• Every time the brazier is removed for cleaning, it must always be put back properly in the work position before using the product,

completely removing any residual dirt left on the support base

• Pellets must never be loaded in the brazier manually, either before ignition or during operation.

• The build-up of unburnt pellets following a failed ignition must be removed before repeating ignition. Also check that they are fed

correctly and that the combustion air inlet/smoke outlet are regular.

• If ignition fails repeatedly, immediately suspend use of the product and contact a qualied technician to check its operation.

Compliance with these indications is absolutely sucient to ensure proper operation and to avoid any type of problems with the product.

If the aforementioned precautions are not taken, and during ignition the brazier is overloaded with pellets thus generating anomalous

smoke in the combustion chamber, carefully follow the indications below:

• Do not disconnect electrical power to the product for any reason whatsoever: this would stop the smoke extractor, releasing smoke

into the environment.

• Take the precaution of opening the windows to ventilate the installation room from any smoke in the environment (the chimney

might not work properly)

• Do not open the re door: this would compromise regular operation of the smoke extraction system to the chimney.

• Simply switch the stove o by operating on the on-o button on the control panel (not the rear power supply socket button!) and

move away until smoke has been completely extracted.

• Before attempting re-ignition, clean the brazier and its air passage holes completely of all deposits and unburned pellets. Put

the brazier back in place, removing any residue from its support base. If ignition fails repeatedly, immediately suspend use of the

product and contact a qualied technician to check its operation and the chimney.

30-CLEANING

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.

Disconnect the product from the 230V power supply before performing any maintenance operation

The product requires little maintenance if used with certied good quality pellets.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

Brazier cleaning

Before ignition, always clean the brazier “T” and remove any ash or deposits from it that might obstruct the air ow holes, paying attention

to hot ash. In the case of ignition failure, or if fuel in the hopper runs out, unburned pellets may accumulate in the brazier. Always empty

the residue in the brazier before each start-up. Only if ash is completely cold may a vacuum cleaner be used to remove it. In this case,

use a suitable vacuum cleaner to remove small sized particles.

EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER

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. If high quality pellets are used, you will normally only need to use a brush to restore the optimal operating conditions of

the component.

Cleaning the ash collection compartment

To clean the ash collection compartment, you must open the rebox door “F”, lift grille “g” simply by rotating until it rests against the stove’s

rebox. Wipe away any residual ash before lowering the grate “g”. The quality of the pellets used and user experience will determine the

required cleaning frequency. However, it is recommended not to exceed 2 or 3 days.

Attention! When cleaning is completed, remember to put the brazier in and lower grate “g”.

30-CLEANING

CLEANING THE GLASS

It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specic detergent and clean with a cloth.

ATTENTION!

Do not use abrasive products and do not spray the glass cleaning product on the painted parts and on the door

gaskets (ceramic bre cord).

CLEANING THE AIR FILTER

A wire mesh air lter is found at the back of the stove (for the models tted with it), whose purpose is to prevent dirt entering the motor

body and the internal sensor.

It is recommended to check that the lter is clean every 15/20 days. If needed remove u or the material that has deposited on it.

Inspection and cleaning are required more frequently if there are pets in the house.

Simply remove the lter to clean. To clean it use a brush or a damp cloth or compressed air. Set it back in place by simply pressing it

(interlocks).

The lter is made of metallic mesh and is soft and exible to the touch therefore, when cleaning, be careful not to

crush or damage it. In the event of breakage it must be replaced.

ATTENTION!

Never let the stove work without the air lter tted. MCZ cannot be held liable for any damage caused to the internal

components if this requirement is not complied with.

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 dicult to

remove it due to moisture compacting it over time.

ATTENTION:

Cleaning is mandatory to be performed at the end of the season by an authorised and skilled technician so that even

the seals can be replaced.

CLEANING THE LOWER COMPARTMENT

To clean the lower compartment from the ash, open the hearth door of the stove “ F “ and remove the lower panel “P” as indicated in part

1 of the manual.

Now loosen the four screws “y”, remove the plate “n” and the gasket “o”. Use the nozzle of a vacuum cleaner to remove any ash and soot

that may have built up in the lower exchanger (smoke extractor) indicated by the arrow.

Before putting the cap “n” back, it is recommended to change the gasket “o”.

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 removing the cap to clean the lower

compartment “n” (see previous paragraph), use a 1 metre long exible brush to scrape the walls of the rebox (see arrow) to make the

ash fall into the lower compartment.

Then remove the upper calorite plate “J”. To do this open the rebox door, lift the top of the calorite plate “J” upwards, tilt it to the right or

to the left in order to release it from the supports and remove it.

30-CLEANING

Use a exible brush to scrape the walls of the rebox (see arrow - respectively to the right and to the left of the rebox) 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.

30-CLEANING

CLEANING THE SMOKE EXPULSION SYSTEM AND GENERAL CHECKS

Clean the smoke outlet system, especially around the Tee ttings, elbows and any horizontal sections of the smoke duct.

For information on periodically cleaning the ue, contact a skilled chimney sweep.

Check the seal of the ceramic bre gaskets on the door of the stove. If necessary, order new replacement gaskets from the retailer or

contact an authorised service centre to carry out the operation.

ATTENTION:

The frequency with which the smoke outlet system is cleaned depends on the use of the stove and the type of

installation.

We recommend relying on an authorised service centre for end-of-season cleaning and maintenance, as they will

carry out all of the previously mentioned work and inspect the stove components.

PERIODICAL CHECK OF THE DOOR CLOSURE

Make sure the door closure ensures correct sealing action (with the “paper sheet” test) and that when the door is closed, the closing block

(X in the gure) 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.

30-CLEANING

SHUTDOWN (end of season)

At the end of each season, before switching the product o, 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. This way the paint will protect the inner parts of the combustion chamber,

blocking any type of oxidative process.

When not in use the appliance must be disconnected from the mains power supply. It is recommended to remove the

power cable for additional safety, especially in the presence of children.

If, when the stove is switched on again, the control panel display does not light up, it means that it may be necessary to replace the service

fuse.

There is a fuse box next to the power socket. After having disconnected the plug from the socket, open the fusebox cover with a screwdriver

and replace the fuses if necessary (5x20 mm T delayed/ 3. 15 A 250 V) - seek assistance from an authorised and qualied technician.

CHECKING THE INTERNAL COMPONENTS

ATTENTION!

The internal electromechanical components must only be checked by qualied personnel whose technical expertise

includes combustion and electricity.

We recommend for this yearly maintenance to be carried out (with a scheduled service contract). This operation consists of a

visual and functional inspection of the internal components. A summary of the checks and/or maintenance operations that are essential

for the correct operation of the product is provided below.
