All parts must be replaced with original spare parts.

WARNINGS FOR THE CORRECT DISPOSAL OF THE PRODUCT.

The owner is the sole party responsible for demolishing and disposing of the product. This must be performed in compliance with laws related to safety and environmental protection in force in his/her country.

At the end of its working life, the product must not be disposed of as urban waste.

It must be taken to a special differentiated waste collection centre set up by the local authorities or to a retailer that provides this service.

Separating and recycling prevents potential negative effects on the environment and health (often caused by inappropriately disposing of product parts). It also allows materials to be recovered in order to obtain significant savings in energy and resources.


2-FUEL

The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always observe the regulations in force in the country of installation.

PELLETS

Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be produced without glue or binders.

The market offers different types of pellets with characteristics that vary according to the wood mixtures used. The most common diameter on the market is 6 mm (although 8 mm diameter is available too) with a length, on average, of between 5 and 30 mm. A good quality pellet has a density of between 600 and 750 or more kg/metres cubed and a water content that accounts for 5 to 8% of its weight.

Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner combustion than that of fossil fuels.

While good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is around 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg bags, therefore, storing them is very convenient.

15 Kg BAG OF FUEL

Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.

The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must be cleaned.

The main quality certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2 according to EN14961-2. These certifications include, for example, ENPlus , DINplus , Ö-Norm M7135, and in particular, guarantee the following characteristics:

• calorific value: 4.6 ÷ 5.3 kWh/kg.

• Water content: ≤ 10% of the weight.

• Percentage of ash: max 1.5% of the weight.

• Diameter: 6±1/8±1 mm.

• Length: ≤ 40 mm.

• Content: 100% untreated wood without the addition of binding substances (max 5% bark).

• Packaging: in sacks made from ecologically compatible or biologically decomposing material.

The company strongly recommends using certified fuel for its products (ENplus, DINplus, Ö-Norm M7135).

Poor quality pellets or others that do not comply with the characteristics specified previously may compromise the operation of your product and can therefore make the guarantee and product liability invalid.

3-INSTALLATION

FOREWORD

The installation position must be chosen according to the room, to the smoke extraction system, to the chimney flue. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney cap. The manufacturer declines all responsibility in the event of installations that do not comply with the laws in force, incorrect room air exchange, electrical connection non-compliant with the standards and inappropriate use of the appliance. The installation must be carried out by a qualified technician, who must issue a declaration of conformity of the system to the purchaser and will assume full responsibility for final installation and consequent good operation of the product.

In particular one must ensure that:

• there is a suitable combustion air inlet and smoke outlet in compliance with the type of product installed

• other stoves or devices installed do not cause depression in the room where the product is installed (for sealed appliances only, a maximum of 15 Pa of depression in the room is allowed)

• when the product is switched on there is no reflux of smoke in the room

• fumes extraction takes place in total safety (sizing, smoke seal, distances from flammable materials..).

We especially recommend to check the data tags of the flue for the safety distances that must be observed in presence of combustible materials and the type of insulating material to be used. These indications must be followed strictly to prevent serious harm to people and the integrity of the home.

The installation of the appliance must ensure easy access to clean the appliance itself, the smoke outlet pipes and the flue. It is forbidden to install the stove in rooms with a fire hazard.

Installation in studio flats, bedrooms and bathrooms is only allowed with sealed or closed appliances equipped with suitable combustion air ducting directly outside. Always maintain adequate distance and protection in order to prevent the product from coming into contact with water.

In the event there are several appliances installed, the external air inlet must be sized accordingly.

MINIMUM DISTANCES

It is recommended to install the stove detached from any walls and/or furniture, with a minimum clearance to allow effective aeration of the appliance and a good distribution of heat in the room. Observe the distances from flammable or heat-sensitive objects (sofas, furniture, wood panelling, etc..) as specified. The front distance from flammable materials must be at least 80 cm.

If particularly delicate objects are present, such as furniture, curtains or sofas, increase the stove clearance accordingly.

If the floor is made of wood, it is recommended to fit a floor protection sheet in compliance with the Standards in force in the country of installation.

Non-flammable walls Flammable walls

CUTE/THEMA

A = 5 cm

B = 5 cm

A = 5 cm

B = 5 cm

If the floor is made of combustible material, it is recommended to use protection made of non-combustible material (steel, glass...) that also protects the front from falling combusted material during cleaning operations.

The appliance must be installed on a floor with adequate load capacity.

If the existing construction does not meet this requirement, one must take appropriate measures (for example a load distribution plate).


4-FLUE

FOREWORD

The Chimney Flue chapter has been drawn up with reference to the provisions of European Standards (EN13384 - EN1443 - EN1856 -

EN1457).

The chapter provides instructions for installing a chimney flue efficiently and properly, but under no circumstances is it a substitute of the

Standards in force, which the qualified technician must be in possession of. Check with local authorities whether there are any restrictive regulations in force regarding the combustion air inlet, the smoke outlet system, the flue or the chimney cap.

The company declines all liability relating to the poor functioning of the stove if this is due to the use of an insufficiently sized flue in violation of the Standards in force.

CHIMNEY FLUE

The flue or chimney is of great importance for the proper operation of a solid fuel-burning heating appliance with forced draught, as modern heating appliances have high efficiency with cooler flue gasses and consequently less draught, it is therefore essential that the flue is built up to standard and always kept in perfect order. A flue that serves a pellet/wood fuelled appliance must be at least category

T400 (or greater if the appliance requires so) and resistant to soot fires. Smoke must be extracted through a single flue made of insulated steel (A) or an existing flue that complies with the intended use (B).

A simple air shaft made of cement must be suitably lined. In both solutions there must be an inspection cap (AT) and/or inspection hatch

(AP) - FIG.1.

It is forbidden to connect more than one wood/pellet-burning appliance or of any other kind (vent hoods... ) to the same flue.

TECHNICAL CHARACTERISTICS

Have the efficiency of the flue checked by an authorised technician.

The flue must be sealed against flue gasses, in a vertical direction without narrowing, be made with materials impermeable to smoke, condensation, thermally insulated and suitable to resist normal mechanical stress over time (we recommend fireplaces made of A/316 or refractory material with insulated round section double chamber). Be suitably insulated externally to avoid condensation and reduce smoke cooling. It should be separated from combustible or flammable materials with an air gap or insulating materials: check the distance specified by the manufacturer of the fireplace according to EN1443. The chimney opening must be in the same room as the appliance, or at most in the adjoining room, and have a soot and condensation collection chamber beneath the opening, and be accessible via a sealed metal hatch.

SIZING

The depression (draught) of a flue depends on its height. Check the depression with the values indicated in the technical characteristics.

The minimum height of the chimney is 3.5 meters.

The interior cross-section of the flue can be round (best), square or rectangular (the ratio between the internal sides must be ≤1.5) with the sides joined with a minimum radius of 20 mm. The dimension of the cross-section must be minimum Ø100mm .

The cross-sections/lengths of the chimneys shown in the technical data tables are indications for correct installation. Any alternative configurations must be correctly sized in accordance with the general method of calculation of UNI EN13384-1 or other proven efficiency methods.

Below is a list of some flues available on the market:

AISI 316 steel chimney with double chamber insulated with ceramic fibre or equivalent resistant up to

400°C.

Refractory chimney with double insulated chamber and external lightweight concrete cladding with cellular material such as clay.

Traditional square-section clay chimney with insulating

Avoid products with an internal rectangular section empty inserts.

where the larger side is 1.5 times the smaller side (e.g.

20x40 or 15x30).

4-FLUE

MAINTENANCE

The flue must be kept clean, since the deposit of soot or unburned oils reduces the cross-section reducing the draft and thus compromising the efficient operation of the stove and, if large build-ups accumulate, can catch fire. The flue and chimney must be cleaned and checked by a qualified chimney sweep at least once a year. Once maintenance has been performed, request a written declaration that the system is safe.

Failure to clean the system jeopardises safety.

CHIMNEY CAP

The chimney cap is a crucial element for the heating appliance to work properly: we recommend a wind proof chimney cap (A), see Figure

7.

The area of the openings for smoke extraction must be at least double the cross-section of the smoke duct/flue system, and arranged so that smoke extraction is ensured even in strong wind. The chimney must prevent rain, snow or animals from entering the chimney. The height of outflow into the atmosphere must be beyond the reflux area due to the shape of the roof or any obstacles near the outlet

(see Figures 2-3-4-5-6).

EXTERNAL AIR INLET

It is mandatory to provide an adequate external air intake that supplies the combustion air required for the product to work properly. The flow of air between the outside and the installation room may be direct, through an inlet in an external wall of the room; or indirect, via air intake from adjoining rooms and connecting permanently with the installation room (see Figure 9 b). Adjoining areas may not include sleeping areas, garages or general areas that present a fire hazard. During installation one must check the minimum clearances required for air intake from outside. Take into account the presence of doors and windows that could interfere with the proper flow of air to the stove (see diagram below).

The air intake must have a minimum total net area of 80 cm2: the surface must be increased accordingly if within the room there are other active generators (for example: electric fan for stale air extraction, kitchen hood, other stoves, etc...), which could cause cause depression in the room. One must verify that, with all the equipment on, the pressure drop between the room and the outside does not exceed a value of 4 Pa. If necessary increase the intake section of the air inlet, which must be made at floor level and always protected with a birdproof outer protection grid and in such a way that it cannot be obstructed by any object.

It is possible to connect the air required for combustion directly to the outside air inlet, with a pipe of at least Ø50mm, with maximum length of

3linear metres; each pipe bend shall be considered equivalent to a linear metre. To attach the pipe see the back of the stove.

For stoves installed in studio flats, bedrooms and bathrooms (where allowed), it is mandatory to connect the combustion air outside. In particular for sealed stoves the connection must be sealed in order not to compromise the overall sealed characteristic of the system.

Use smoke ducts with a diameter of 80mm or 100mm depending on the type of system, with silicone gaskets or similar gaskets that can withstand the high operating temperatures of the appliance (min. T200 class P1). The use of flexible metal hoses made of fibre cement or aluminium is forbidden. For direction changes, we always recommend using a T fitting with an inspection cap allowing easy access to clean the pipes. Always ensure that the inspection cap is put back in place and sealed hermetically with the relevant seal intact after cleaning.

It is forbidden to connect several appliances to the same smoke duct, or the outlet from the overhead hoods. It is forbidden to extract the combustion products directly through the wall, whether into indoor spaces or outdoors.

The smoke duct must be at a minimum distance of 400 mm from flammable or heat-sensitive structures.

LOADING THE PELLETS

Fuel is loaded from the upper part of the stove by lifting the door.

Pour the pellets in slowly so that it is deposited at the bottom of the hopper.

Never remove the protection grid inside the hopper. When loading, do not let the pellet bag come into contact with hot surfaces.

No other type of fuel other than pellets is to be inserted into the hopper, in compliance with above-mentioned specifications.

Store the spare fuel at an adequate safe distance.

Do not pour pellets directly onto the brazier but only into the hopper.

Most of the stove surfaces are very hot (door, handle, glass, smoke outlet pipes, hopper door etc.), therefore it is recommended to avoid coming into contact with these parts without appropriate protective clothing.

LOADING THE PELLETS



PRECAUTIONS BEFORE START-UP

GENERAL PRECAUTIONS

Remove any objects that may burn from the brazier (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 required amount of pellets in time to light the flame.

CANCEL THE FAILED IGNITION ALARM BY PRESSING AND HOLDING THE ON/OFF KEY FOR A FEW SECONDS. REMOVE THE

PELLETS LEFT IN THE BRAZIER AND REPEAT THE START-UP. (SEE "SAFETY DEVICES/ALARMS" PARAGRAPH)

If after repeated attempts, the flame fails to ignite, despite a regular flow of pellets in the brazier, which must rest snugly against the slots and be clean without any ash incrustations.

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 first 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 specific colour. (See "Pellet stove accessories")

It is good practice to ensure effective 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 first.

This will prevent damaging the ceramic or serpentine stone tiles, the welds and the steel structure.

DO NOT EXPECT HEATING EFFICIENCY IMMEDIATELY!!!

7-REMOTE CONTROL MAX

GENERAL FEATURES OF THE LCD REMOTE CONTROL

The remote control works at a transmission frequency of 434.5 MHz. Power the product with 3 AAA batteries as follows:

Remove the battery compartment cover by pressing and lifting according to the arrow

Insert the batteries observing the correct polarity (+) and (-)

Close the battery compartment cover.

When the remote control is powered it automatically prompts to set the time.

The remote control has a special icon on the display to indicate when the batteries are almost flat. If the flat battery icon appears, the batteries are almost flat and the remote control is about to switch off.

Used batteries contain metals which are harmful to the environment, so they must be disposed of separately in appropriate containers.

REMOTE CONTROL OPERATION

General rules

By pressing key A for 1” the product is switched on and off. Key C is used to make all changes. Key E is used to confirm the changes. By pressing key B one selects the product operating mode. Via key D one browses the FAN and SLEEP setting.

Whichever the mode is, press key A briefly (or leave the keypad idle for 7”) to go back to the initial display.

INITIAL SETTINGS

Setting the time

Both with the remote control on and off, by pressing keys B + E at the same time for 3” one accesses the time/day setting mode.

The hour digits will start to flash; they can be changed with key C . By pressing key E the changes are confirmed.At this point the minutes digits will start to flash.

Follow the same modify/confirm procedure, one will then go onto the time display mode (12h or 24h) and finally the day will start to flash. Confirm this data to exit the settings.

NOTE: each time the remote control is powered, the time is reset and the display automatically enters the time setting mode.

°C – °F setting

Only with the stove switched off, by pressing key B for 5” one changes the unit of measure of the temperature, from Celsius to Fahrenheit and vice versa.

SETTING THE OPERATING MODE

With the remote control switched on, key B allows to set one of the 4 product operating modes. Figure 1-2-3-4 displays the 4 basic displays, respectively:

Manual, Automatic, Timer and Eco mode.

MANUAL Mode (MAN)

In this mode one can set the flame power manually (5 levels - act directly on key C to change) and the ventilation power on 5 levels + auto. Figure 1

AUTOMATIC Mode (AUTO)

In this mode one can set the desired room temperature, and the stove will modulate the flame power automatically to reach the temperature. Ventilation can be adjusted on 5 levels + auto. Figure 2

TIMER Mode (TIMER)

Select this operating mode to switch the product on and off automatically, according to 6 customised time slots (P1 – P6). The following can be set for each time slot:

• Switch-on time

• Switch-off time

• Desired room temperature in the time slot

• Days of the week in which the time slot is active

When the stove is switched on (manually via key A or automatically via a time slot) the product works in the automatic mode described above. A time slot appears automatically when it is active (P1 in figure 3 ) and the desired temperature is changed according to the value set in the time slot. However, the user can always modify this value as desired and in real time.

Refer to the relevant paragraph to learn how to set the time slots.

ECO Mode (ECO)

This mode is activated/disabled with the remote control switched on by pressing key B for 5”.

ECO is an automatic mode with the only difference that if the set temperature is reached and remains so for the following 20 minutes

(despite flame modulation), the product switches off and remains on stand-by until the room temperature drops 2 degrees below the desired temperature (and in any case for at least 5 minutes from the last shutdown). The product is then switched on again. Figure 4

If the room is not sufficiently insulated, flame modulation does not allow the set temperature to stay satisfied for 20 consecutive minutes and the product will not switch off.

NOTE: It is recommended to use the ECO mode only in well-insulated rooms in order to prevent start-up and shutdown from occurring within short periods of time.

The remote control remains on even when the product is off when in ECO mode, in order to indicate that this shutdown is only temporary. Obviously, if the product is switched off via key A, ECO mode is exited and the product remains off.

Up to 6 automatic start-up and shutdown time slots (E1 – E6) can also be set in ECO mode, which are independent from those of TIMER mode (P1 – P6). If they have been activated, TIMER-ECO appears on the display ( figure 5 ) permanently, even if the remote control is switched off.

Refer to the relevant paragraph to learn how to set the time slots.

NOTE: If the remote control is switched off due to TIMER, ECO cannot be restarted until the user intervenes (key A) or when the next valid time slot starts. Combined use of TIMER and ECO modes requires a good knowledge of the product operating logic.



VARIOUS SETTINGS

Room ventilation

Room ventilation can be adjusted as desired in all 4 operating modes described above. Simply perform this operation: from the basic display, press key D to access the VENTILATION adjustment mode ( figure 6 ). Then press key C to set the desired ventilation by selecting one of the 5 levels available, independent from the flame level. The “auto” option can also be selected, which automatically links the room ventilation speed to the flame level.

In short: flame set on 1 > ventilation set on 1; flame set on 3 > ventilation set on 3; flame set on 5 > ventilation remains set on 3 (to make operation more silent as it is in automatic mode).

In products with 2 room fans (comfort air models) via key D one can scroll and set the speed of the individual fans

(identified with 1 or 2 above the level bars).

Modifying the TIMER time slots

To modify a time slot, display it as described in the previous paragraph and then press key E . The first parameter to be set will start to flash, i.e. room temperature. Press key C to modify the value and key E to confirm and set the next parameter. The parameters of a time slot can be set in the following sequence:

• Room temperature. Can be set between 5° and 35°C. 2 dashes "--" appear if set below 5°C or above 35°C, and if this is confirmed, the programme is disabled(therefore, the product will not be switched on).

• Switch-on time. The value is adjusted in 10 minute intervals (from 00:00 to 23:50)

• Switch-off time. The value is adjusted in 10 minute intervals (from 00:10:00 to 24:00).

• Days of the week in which the programme is active. Monday (MO) will start to flash, followed by the other days of the week. Use key

C to activate/disable the day. The activated days will be displayed on a dark background. When the Sunday (SU) setting is complete, press key E to exit the editing page and return to the time slots display.

By pressing key D at any time one exits the time slot editing mode, saving all variations confirmed with key E up to that time, and one goes back to the time slot display condition.

While by pressing key A (or leaving the keypad idle for 30”) one goes directly to the basic display, saving all variations confirmed with key E up to that time.

Activating the TIMER-ECO time slots

In ECO mode one can activate up to 6 time slots, customising switch-on and switch-off (E1 – E6): by pressing key D for 2” the TIMER activation/disabling function will appear ( figura 9 ). If the ON option is confirmed one can display/modify the 6 time slots of the TIMER-

ECO with the same procedure described previously for the TIMER. By confirming the OFF option, the TIMER is disabled and the product goes back to operate in ECO mode without active time slots.

REMOTE CONTROL SYNCHRONIZATION

When the product is started up for the first time, it may be necessary to synchronize the new remote control with the stove. To do this, follow these simple instructions:

• connect the socket to the stove and turn on the power switch

• make sure the selector D on the emergency panel is in the REMOTE position

• when the first message appears on the emergency panel’s display, use a pointed object to press the chased G button (toothpick, etc.)

• the panel’s display will show 3 flashing lines “---“. Press the remote control’s on/off button to launch the learning process.

10-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 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 off 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 stays off.

FAILED START-UP

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

TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED.

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.

Faulty air flow rate sensor

Routine maintenance alert

Move the remote control within the reception range of the stove (or change the remote control batteries in the event they are flat). The alarm alerts will disappear as soon as the appliance receives a new signal from the remote control. A simple way of forcing signal transmission to the stove is by pressing button B (which changes the operating mode from manual to automatic and vice versa).

The structure is too hot because the product has been used for too long at the maximum power or due to poor ventilation or because the air fans are faulty. When the product is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A13.

Once the alarm is canceled, the product can be switched on normally.

This alarm does not block the stove, just a warning is displayed. Contact an authorised service centre to have the component replaced.

When this flashing message appears upon start-up it indicates that the preset operating hours before maintenance is due have elapsed and that an MCZ qualified technician must be contacted for maintenance.

Exiting the alarm conditions

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

• Put selector D on the rear emergency panel on OFF for a few seconds, until the 3 digit alarm identity code disappears. The red LED stops flashing and the sound signal is silenced by performing the steps below.

• Put selector D back in the REMOTE position, to control the operation of the stove via the remote control.

• Switch off the remote control and switch it on again if one wants to restart the stove.

Only if alarm A12 is triggered (no communication between the remote control and the stove), the stove stay on according to the last mode set and automatically exits the alarm mode when the first signal is received from the remote control.

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 chimney flue (“A05”)

The block is signalled on the display and with a sound signal. In this situation the shutdown stage is activated automatically.When this procedure is started, any test operation to restore the system is useless. 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 due to poor ventilation or because the air fans are faulty.

When the product is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel alarm A03 . Once the alarm is canceled, the product can be switched on normally.

If “ A04 ” appears: The stove switches off automatically. Let the stove cool down for a few minutes and then switch it on again. Check the smoke expulsion and the type of pellets used.

If “ A05 ” appears: the door has been left open for too long or a significant 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 flue. (it is recommended that this operation is carried out by an MCZ qualified technician.

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


12-CLEANING

EXAMPLE OF A CLEAN BRAZIER EXAMPLE OF A DIRTY BRAZIER

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 certified good quality pellets.

DAILY OR WEEKLY CLEANING PERFORMED BY THE USER

Before each lighting

Clean the ash and any deposits in the brazier that could clog the air passage holes.

If the pellets in the hopper run out, unburned pellets may accumulate in the brazier. Always empty the residue in the brazier before each ignition.

REMEMBER THAT ONLY A CORRECTLY POSITIONED AND CLEAN BRAZIER CAN GUARANTEE IGNITION AND OPTIMAL

OPERATION OF YOUR PELLET PRODUCT.

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

After a long period of inactivity, (using a vacuum cleaner with a long pipe) remove any traces of pellets in the hopper that could have absorbed moisture and are no longer suitable for combustion.

CLEANING THE GLASS

It is recommended to clean the ceramic glass with a dry brush, or if it is very dirty, spray a little specific 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 fibre cord).

40

12-CLEANING

CLEANING THE AIR FILTER

When the stove is installed, one must fit the rear of the stove with the wire mesh air filter, whose purpose is to prevent dirt entering the motor body and the internal sensor.

It is recommended to check that the filter is clean every 15/20 days. If needed remove fluff or the material that has deposited on it.

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

To clean, simply turn the knob that holds the filter on the air intake pipe and remove the filter by turning it in the direction indicated by the arrow. To clean it use a brush or a damp cloth or compressed air.

The filter is made of metallic mesh and is soft and flexible 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 filter fitted. MCZ cannot be held liable for any damage caused to the internal components if this requirement is not complied with.


12-CLEANING

CHECK EVERY 2 / 3 DAYS

Clean and empty the ash pan “C” bewaring of hot ashes.

The ash can be removed when it is completely cold with a vacuum cleaner. In this case, use a suitable vacuum cleaner to remove particles of a certain size. 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.

Once the operation is complete, put the ash pan back in place under the brazier making sure it is inserted properly.

Open the stove door, remove brazier “A” and clean around it. Then remove ash pan “C” and grate “B”. Clean everything with the vacuum cleaner and reassemble the parts.

PERIODIC CLEANING PERFORMED BY A QUALIFIED TECHNICIAN

CLEANING 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 the humidity compacting it over time.

Remove the front inspection cap “ E ” by undoing the three screws “ F ”. Remove any ash residues using the vacuum cleaner.

E F

CLEANING THE SMOKE DUCT AND GENERAL CHECKS

Clean the smoke outlet, especially around the fittings, bends and any horizontal sections.

For information on cleaning the flue, contact a chimney sweep.

After having cleaned the smoke duct remove the cap “ S ”, on the back of the stove, via the four screws “ V ” and vacuum any ash deposits. If needed replace the gasket “ U ” and put the cap “ S ” back in place.

Check the seal of the ceramic fibre 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 boiler 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.

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.

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.

The service fuse may have to be replaced if the control panel display does not switch on when the product is switched on again by pressing the main switch on its side.

There is a fusebox on the side of the product, near the power socket. Open the fusebox cover with a screwdriver and replace the fuses if necessary (3.15 A delayed) - seek assistance from an authorised and qualified technician.
