The poorer the quality of the fuel, the more frequently will intervention be necessary for cleaning the internal parts, such as the grate and the combustion chamber.

Fuel pellets

15 Kg sack of fuel

2. Theoretical notions for installation

2.1. 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 comes from the lignin which is contained in the wood itself, and allows the production of pellets without the use of glues or binders.

The market offers different types of pellet with characteristics which vary depending on what mixture of woods is used. The diameter varies between 6 mm and 8 mm, with a standard length in the range 5 mm to 30 mm. Good quality pellets have a density which varies between 600 kg/m3 and 750 kg/m3, with a moisture content which varies from 5% to 8% by weight.

Besides being an ecological fuel (exploiting timber residues to the maximum and achieving cleaner combustion than is possible with fossil fuels), pellets also have technical advantages. While good-quality timber has a calorific power of 4.4 kW/kg (with 15% moisture, therefore after about 18 months' seasoning), the equivalent figure for pellets is 4,9 kW/kg.

To ensure good combustion, the pellets must be stored in an area that is free of humidity and protected from dirt. The pellets are usually supplied in 15 kg. sacks, so storing them is very convenient.

Good quality pellets ensure good combustion, thus lowering the emission of harmful agents into the atmosphere.

The main certifications of quality for pellets in the European market are DINplus and Ö-Norm M7135; these ensure respect of:

 Calorific power: 4.9 kW/kg  Water content: max 10% of weight  Percentage of ashes: max 0,5% of weight  Diameter: 5 – 6mm  Length: max 30mm  Contents: 100% untreated wood, with no added bonding

substances (bark percentage 5% max)

 Packaging: in sacks made from ecologically compatible or

biologically decomposing material

MCZ strongly recommends using certified fuel in its stoves (DINplus e Ö-Norm M7135).

The use of fuel of inferior quality or not conforming to the specification given above compromises the running of your stove and can therefore lead to the termination of the guarantee and of the manufacturer's responsibility for the product. MCZ pellet stoves run exclusively on pellets with a diameter of 6 mm (only for Italy) and 6-8 mm (European countries) with lengths that go from 5 mm to 30 mm.

IMPORTANT! Installation and assembly of the stove must be

carried out by qualified personnel.

IMPORTANT! The stove must be connected to a flue pipe or a

vertical duct which can discharge the fumes at the highest point of the building.

The fumes are however derived from the combustion of wood products, and if they come into contact with or close to walls, they can make dirty marks.

Also take care because the fumes are very hot but almost invisible, and can cause burns on contact.

The holes for the passage of the smoke pipe and for the intake of air from outside should be made before positioning the stove unit.

2.2. PRECAUTIONS FOR INSTALLATION

The stove must be installed in a suitable position to allow the normal operations of opening and ordinary maintenance.

The site must be:

 capable of providing the environmental conditions for operation  equipped with power supply 230V 50 Hz  capable of taking an adequate system for smoke discharge  provided with external ventilation  provided with an earth connection complying with CEI 64-8

The stove must be connected to a flue pipe or an internal or external vertical duct conforming to current standards UNI 7129 - 7131 9615.

The stove must be positioned in such a way that the electrical plug is accessible.

Technical service - Rights reserved MCZ GROUP S.p.A. - Reproduction prohibited

It is not permissible to install the stove in bedrooms, bathrooms, or in a room where another heating appliance is installed (fireplace, stove etc.) which does not have its own independent air intake.

Locating the stove in a room with an explosive atmosphere is prohibited. The floor of the room where the stove is to be installed must be strong enough to take its weight.

If the flooring is made of wood, provide a floor protection surface in compliance with current national standards.

Example of pellet stove installation

2.3. OPERATING AREA

For proper functioning and a good temperature distribution, the stove should be positioned in a location where it is able to take in the air necessary for combustion of the pellets (about 40 m3/h must be available), as laid down in the standard governing the installation and in accordance with local national standards.

The volume of the room must not be less than 30 m3. The air must come in through permanent openings made in walls (in

proximity to the stove) which give onto the outside, with a minimum cross-section area of 100 cm2.

These openings must be made in such a way that it is not possible for them to be obstructed in any way.

Alternatively, the air can be taken from rooms adjacent to the one which needs ventilating, as long as they are provided with an air intake from the outside, and are not used as bedrooms or bathrooms, and provided there is no fire risk such as there is for example in garages, woodsheds, and storerooms, with particular reference to what is laid down in current standards.

If the walls are not flammable position the stove with a minimum rear

clearance of at least 10 cm. If walls are flammable maintain a minimum rear distance of 5 cm (A)

and side distance of 10 cm (B) for Ego/Star Air stoves. For Comfort air stoves maintain a minimum rear distance of 20 cm (A), side distance of 20 cm (B) and front distance of 100 cm.

If the room contains objects which are believed to be particularly delicate, such as drapes, sofas and other furniture, their distance from the stove should be considerably increased.

2.4. CONNECTION TO THE EXTERNAL AIR INTAKE

It is essential that at least as much air must be able to flow into the room where the stove is installed as is required for proper combustion in the appliance and for the ventilation of the room. This can be effected by means of permanent openings in the walls of the room to be ventilated, which give onto the outside, or by single or collective ventilation ducts.

For this purpose, on the external wall near the stove, a hole must be made with a minimum free cross-section of 100 cm². (equivalent to a round hole of 12 cm diameter or a square hole 10x10 cm), protected by a grille on the inside and the outside.

PELLET STOVES

Chapter 2

INSTALLATION AND USE MANUAL

Theoretical notions for installation

Technical service - Rights reserved MCZ GROUP S.p.A. - Reproduction prohibited

It is not compulsory to connect the air intake directly with the stove (so that it draws air directly from outside), but it is essential at all events to ensure an airflow of 50 cubic metres per hour by the use of a hole of the dimensions given. See standard UNI 10683.

Pipes and unions with suitable gaskets must always be used, to guarantee a hermetic seal.

All sections of the smoke duct must be inspectable and removable to enable periodic internal cleaning. Tee connectors with inspection caps should be used.

IMPORTANT! All 90 degree changes of direction in the flue pipe must be fitted with suitable tee connectors to allow the possibility of inspection. (see accessories for pellet stove)

It is absolutely prohibited to fit a grille on the end of the discharge pipe, because it could lead to poor running of the stove.

FOR CONNECTION TO THE FLUE PIPE, NOT MORE THAN 2-3 METRES OF HORIZONTAL PIPE MUST BE USED AND NOT MORE THAN THREE 90° CURVES MUST BE USED IT IS ALSO ADVISABLE NOT TO EXCEED 6 METRES IN LENGTH WITH THE PIPE Ø 80 mm

Example of pellet stove installation

The air intake must also:

 communicate directly with the room where the stove is installed  be protected by a grille, metal mesh or suitable guard, as long as

this does not reduce the area below the minimum.

 be positioned in such a way as to be impossible to obstruct

2.5. CONNECTION OF SMOKE DISCHARGE PIPE

When making the hole for the passage of the smoke discharge pipe, it is necessary to take into account the possible presence of flammable materials. If the hole will be going through a wall made of wood or any other material which is sensitive to heat, the INSTALLER MUST first of all use the special wall union (diam.13cm 13cm minimum) and properly insulate the pipe of the stove that passes through it, using adequate insulation materials (thickness 1.35cm with minimum thermal conductivity of 0.07 W/m°K). The same is true if the stove pipe must run through vertical or horizontal stretches passing in proximity (min.20cm) to the heatsensitive wall As an alternative we recommend the use of insulated pipe, which can also be used on the outside to avoid condensation. The combustion chamber works in low pressure. The smoke duct for the discharge of fumes will also be under low pressure when connected to an efficient flue pipe as directed.

Position the stove bearing in mind all the instructions and considerations above.

2.6. CONNECTION TO THE FLUE PIPE

The flue pipe must have internal dimensions not larger than 20 x 20 cm, or diameter 20 cm. In the event of larger dimensions, or of the flue pipe being in poor condition (for example cracks, poor insulation, etc.), it is advisable to fit a stainless steel pipe of suitable diameter inside the flue pipe throughout its length, right up to the top. Check with suitable instruments that there is a minimum draught of 10 Pa. At the bottom of the flue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the flue pipe, using pipes and connectors as recommended by us. You must ensure that a windproof cowl should be fitted which complies with the standards in force.

2.7. CONNECTION TO AN EXTERNAL FLUE WITH INSULATED OR DOUBLE-WALL PIPE

The external fluepipe must have internal dimensions of minimum 10x10 cm or 10 cm diameter, and maximum 20x20 cm or 20 cm diameter. Check with suitable instruments that there is a minimum draught of 10 Pa. The only type of pipe which is permissible is insulated (double-walled) stainless steel, smooth on the inside, fixed to the wall. Flexible stainless steel pipe must not be used. At the bottom of the flue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the flue pipe, using pipes and connectors as recommended by us. You must ensure that a windproof cowl should be fitted which complies with the standards in force.

2.8. CONNECTION TO THE FLUE PIPE

For proper functioning, the connecting pipe between the stove and the chimney or flue duct must have a slope of not less than 3% in the horizontal stretches, the length of which must not exceed 2/3 metres, and the vertical distance between one tee connector and another (change of direction) must not be less than 1.5m. Check with suitable instruments that there is a minimum draught of 10 Pa. At the bottom of the flue pipe, provide an inspection cap to allow periodic checking and cleaning, which must be done annually. Make a gas-tight connection to the flue pipe, using pipes and connectors as recommended by us. You must ensure that a windproof cowl should be fitted which complies with the standards in force.

2.9. OPERATING PROBLEMS CAUSED BY DRAUGHT DEFECTS IN THE FLUE

Of all the weather and geographical conditions which affect the operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to sunlight, direction of facing), the wind is unquestionably the most decisive. In fact, along with thermal depression caused by the difference in temperature inside and outside of the chimney, there is another type of depression or over-pressure: dynamic pressure caused by the wind. An updraft always increases depression and hence draught. A crosswind increases depression provided the cowl has been installed properly. A downdraft always decreases depression, at times inverting it.

Besides the direction and force of the wind, the position of the flue and the cowl with respect to the roof of the building and the surrounding landscape is important.

The wind also influences the operation of the chimney indirectly by creating high-pressure and low-pressure zones, not only outside the building but inside as well. In rooms directly exposed to the wind (2), an indoor high-pressure area can be created which can augment the draught in stoves and fireplaces, but it can be counteracted by the external high pressure if the cowl is situated on the side exposed to the wind (1). On the other hand, in the rooms on the opposite side from the direction of the wind (3), a dynamic depression can be created which competes with the natural thermal depression developed by the chimney, but this can be compensated for (sometimes) by locating the flue on the opposite side from the direction of the wind (4).

3.2. PREPARATION AND UNPACK ING

STAR AND EGO stoves are delivered with two different packagings:

 The EGO stove has one packaging

o It contains the stove and the steel sides with the

profiles (Fig.1)

 The STAR stove has two packagings

o One contains the stove and the profile for the ceramic

or the soapstone

o One contains the ceramic (fig.2). In this case there will

be a single packaging for the structure (the cardboard with the ceramics will be placed above the packaging with the structure)

o or Soapstone (fig.3) (in this case there are two

packagings structure + soapstone pallet)

Open the packaging, remove the four screws that secure the base of the stove to the pallet, two to the right and two to the left (see figure

4), and position the stove in the selected place, ensuring that it is complies with the above instructions.

The stove body or unit must always be kept in a vertical position when moved, and moved only using carts. Special care must be used to protect the door and the glass from impacts that would damage them.

Moving the product must always be done with care. If possible, unpack the stove in the area where it is going to be installed.

The materials which make up the packaging are not toxic or harmful, so no special procedures for disposal by required.

Their storage, disposal or possible recycling are therefore the responsibility of the final user, in compliance with current legislation on the subject.

Do not store the stove unit or its cladding without their packaging.

If the smoke outlet of the stove is forced or used improperly to lift it or position it, the operation of the stove can be damaged irreparably.

1. Turn the feet clockwise to

lower the stove

2. Turn the feet counter-

clockwise to lower the stove

Position the stove without its cladding and connect it to the flue pipe. Use the four adjustable feet (J) to get the stove correctly levelled so that the smoke outlet (S) is lined up with the connecting pipe (H) . Once the operations for connection are complete, assemble the cladding (ceramics or steel sides).

If the stove needs to be connected to a discharge pipe which goes through the rear wall (to connect up with the flue), take the greatest care to make sure that the joint is not stressed.

TUBO USCITA ARIA CALDA

The air outlet pipe may reach very high temperatures, nearing 200 °C: it is therefore necessary to insulate it appropriately and with suitable materials, wherever it may come into contact with flammable or heatsensitive (e.g. fading of colours, electrical wireways, plasterboard, etc.); it is also necessary to protect persons and animals from voluntary or accidental contact. In any case, always observe the applicable regulations and laws in the region where the appliance has been installed.

It is advisable to provide for insulation along the entire route of the pipe to minimise dispersion and increase heat output to the room.

INSULATOR

3.4. HOT AIR DUCTING CONNECTION ON EGO AND STAR COMFORT AIR MODELS

Once the stove has been positioned correctly, you may start installing the hot air piping.

COMFORT AIR stoves are supplied as standard with an air diverter E, in other words the rear hot air outlet flange is connected to this deviator, which makes it possible to direct the hot air towards the left or right side of the room, in case you do not wish to duct the hot air.

If you wish to duct the hot air, you will need to remove the diverter E, connect the soundproofed union F (optional) which transforms the square outlet into a round one and then make the various connections with purpose-designed MCZ pipes and unions that divert the flow into several hot air diffusers (120x120 mm hot air outlet). Such ducting may also be walled. (SEE OPTIONALS)

It is advisable to make ducts similar in length to distribute the air in a uniform manner, otherwise the hot air will opt for the shortest or less tortuous ducting.

Figure 6 – Air outlet system - front view

B A A B B

Figure 7 – Air outlet system - rear view

When crossing through walls built with flammable materials, the FITTER MUST suitably insulate the stove pipe crossing through it using suitable insulating materials (thickness of 1.3-5 with min. heat conductivity of 0.07 W/m°K).

The pipe introduced into the wall must however be suitably insulated to avoid losing heat and soundproof the air outlet.

In the example in figures 6 and 7 (front and rear view), the air duct is the same length for a total of 8 metres, in other words the piping (B) will measure approximately 4 metres in length each. In the case of different length ducts, the total must in any case always be a maximum of 8 metres (for instance, 3 + 5 metres). In this case, the heat will be distributed in the rooms unevenly.

The air in the room is recirculated through the perforated sheet situated at the rear of the stove C and the holes on the panelled bottom.

It is possible for you to select the volume of air you wish to be released from the front and from the rear of the stove independently, by adjusting the power of the ventilation directly on the remote control.

3.5. INSTALLATION OF AIR FILTER

Before placing the stove near the wall for connection to the flue pipe and to the electrical mains, install the air filter provided with the stove.

The cylindrical filter is composed of a metallic net and is already installed on the stove

The filter must be inserted on the air inlet pipe Ø 5 cm. To remove it, slightly loosen the screw with the knob on the air inlet,

insert the filter matching it with the filter groove with the screw of the knob and then secure it by tightening the knob.

3.6. MAKING THE ELECTRICAL CONNECTIONS

Connect the supply cable first at the rear of the stove and then to an electrical outlet on the wall.

The main switch located on the rear of the stove should be switched on only when you want to light the stove.

Operation

Technical service - Rights reserved MCZ GROUP S.p.A. - Reproduction prohibited

Do not touch the stove 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.

It is good practice to provide plenty of ventilation in the room during the initial lighting, as the stove will give off a small amount of smoke and smell of paint.

At first lighting the stove is already in manual mode. At first, it is advisable to use the only low and medium heating levels (from first to third power level).

Do not demand full heating performance straight away!

4. OPERATION

4.1. PRE-LIGHTING WARNINGS

If necessary, touch up the paint with the aerosol spray in the original colour (see the section "Accessories for pellet stoves").

Do not stay near the stove, and as previously mentioned, ventilate the room. The smoke and the smell of paint will vanish after about one hour of operation. There are no health risks involved.

The stove will be subject to expansion and contraction during the stages of lighting and cooling down, and may therefore make slight creaking noises.

This phenomenon is absolutely normal, the structure being made of sheet steel, and must not be considered a fault.

It is extremely important to be sure not to take the stove to full heat straight away, but to bring it gradually up to temperature.

If in manual mode, use low heating powers (for example 1a-2a-3a ). During subsequent use, you will be able to make use of all available heating power (e.g. 4a-5a ), but remember not to keep the stove running on full power for more than 60-90 minutes.

In this way you will avoid damage to the ceramic panels, the welds and the steel structure.

Try to get familiar with the commands given from the control panel. Try to memorize the messages that the stove provides on the display.

Operation

Technical service - Rights reserved MCZ GROUP S.p.A. - Reproduction prohibited

After long periods of disuse, remove from the hopper (using a vacuum cleaner with an extension) any remains of

pellets which have lain there for some time, since they may have absorbed moisture, which changes their original characteristics and makes them unsuitable for burning.

Never remove the protection grille in the hopper. When filling, do not let the sack of pellets touch any hot surfaces.

Do not place any type of fuel in the hopper other than pellets that are compliant with the specifications provided previously.

4.2. PRE-LIGHTING CHECK

Check that all the safety conditions described above have been met. Make sure you have read and completely understood the contents of

this instruction booklet. Remove any components which might burn from the firebox and from

the glass (various instructions and adhesive labels). Check that the grate A is properly positioned and rests correctly on the

base.

4.3. LOADING THE PELLETS

Fuel is loaded from the upper part of the stove by opening a door. Pour the pellets in the hopper. When empty, it will hold slightly more than a 15 kg sack.

This is easier if performed in two steps:

 Pour half of the contents into the hopper and wait for the fuel

to settle on the bottom.

 Then pour in the rest

 By pressing any of the 4 keys around the display (C D E F) you

access the stove's operation settings screen (level of the flame, fan, set temperature, manual or automatic mode..). From this

level the 4 keys around the display assume “dedicated”

functions, i.e. they directly refer to the corresponding words that appear in the 4 corners of the display (e.g.: the word in the top right hand corner refers to the D key).

 When a setting is modified in any menu level without

confirming the modification using the “OK” key and leaving the

keypad inactive for some seconds, the initial screen reappears and the modifications are not saved.

 If from any menu level the on/off (B) key is briefly pressed, the

display is automatically taken back to the initial screen (stove operating status) without saving any modifications not confirmed with the “OK” key.

To switch the stove on and off, press the key B for 2 seconds on the control panel or the A button on the remote control (if purchased).

After a start-up phase that lasts about 15 minutes, the stove will come up to full operating power.

After the stove is shut down by pressing button B on the remote control or the B button on the control panel, the cooling-off procedure begins. This includes the interruption of fuel loading, the cleaning of the grate and the continuation of ventilation until the stove is sufficiently cold. This phase may last from 20 to 40 minutes depending on how long the stove was lit for and where it is located.

4.6.2. Note on first ignition

After repeated attempts at lighting, if there is no flame even though pellets are flowing normally, check that the grate is correctly positioned. It must be placed where it adheres perfectly to its housing and free of any ash incrustations. If after this check no abnormalities are found, it means that there may be a problem with the stove components or that installation may not have been carried out correctly.

4.7. OPERATING MODE

STAR-EGO stoves have two operating modes: MANUAL and AUTOMATIC.

4.7.1. Manual and automatic

The stove can operate in one of these two different operating modes. MANUAL mode allows only adjustment of the flame from power 1 to

power 5, ignoring any ambient temperature measurement. This mode is indicated by the word MANU on the display of the control.

AUTOMATIC mode, on the other hand, lets you set the desired temperature in the room of installation. The stove will control its power autonomously in order to reach and maintain the established temperature in the room. This mode is indicated by the word AUTO on the control panel.

With this mode you can also use an advanced function called AUTO- ECO which is described later (

paragraph 4.7.4.)

4.7.1.1.

Changing from manual to automatic mode

It is possible to pass from the MANUAL function to the AUTOMATIC function and vice-versa by selecting the related key on the control panel.

4.7.2. Manual mode

In this mode you can only vary the thermal power provided by choosing the flame power. By pressing the switch behind the stove the display of the panel is set to OFF, by pressing any key the screen with the word MENU will appear. With the upper left button select the MANU function (MANUAL mode). In this mode, using the bottom left button (F) it is possible to adjust the 5 heating powers of the stove, while with the bottom right key (C) the speed of the fans is adusted.

4.7.3. Automatic mode

Whereas MANUAL mode lets you simply choose the thermal power provided with no variation of operation over time, AUTOMATIC mode lets you set a temperature to be reached in the room. In this operating mode the stove will automatically vary the thermal power provided so as to keep the temperature in the room constantly at the set value. From the first screen with the word OFF, press any key and the screen with the word MENU will appear. With the upper left button select the AUTO function (AUTOMATIC mode). In this mode using the bottom left button it is possible to adjust the temperature desired in the room.

Upon reaching the desired temperature in the room, the stove will gradually go to minimum power. If instead the room temperature drops below the set limit, the stove will gradually come back up to maximum hearing performance.

The room temperature is highlighted by the control panel using the reading of the probe placed near the switch of the stove.

4.7.3.1. Room sensor

The room probe (B) is located at the back of the stove; should this be near the fumes exhaust tube, we recommend to extract the room

probe so that it sticks out by approximately 10 cm. In this way it will not be affected by the tube's heat and the measured temperature will be near to that of the room.

It is advisable to do this operation during installation, since before extracting the probe (B) it is necessary to take off the clamp (C) that keeps it connected; operation possible by working inside the stove thus without the sides. To extract the probe (B) it is necessary to unscrew the protection cap (A) and slowly pull the probe (B). After extracting the probe (B) sufficiently, close the protection cap (A) again.

Example of operation in AUTO-ECO mode

If the room temperature detected by the sensor and highlighted on the control panel is 15°C and the set temperature is 20°C, the stove will follow a pre-established ramp up to the 5th power. Once 20°C is reached, it goes into standby mode (STANDBY). When the room temperature drops below the value set on the control panel (for example 18°C) and a sufficient shutdown time has elapsed, the stove will come back on automatically and continue running until again reaching 20°C. If the temperature read by the room sensor remains above the value set on the thermostat (for example 20-21°C) the stove will remain off.

In this mode, lighting can be carried out by the user by resetting the thermostat temperature to a value greater than that in the room, or by shutting down the stove by pressing button B for a few seconds and then pressing the same button to re-light the stove.

The “AUTO-ECO” mode does not need to be reset as it remains in

memory from the last use.

4.7.4.1.

Activation /de-activation of AUTO-ECO mode

This mode makes it possible to optimize stove consumption in wellinsulated rooms.

When this option is activated, on the display of the control panel the word AUTO-ECO will appear.

The display of the remote control will show the message AUTO along with the message AUTO-ECO.

From the first screen with the word OFF, press any key and the screen with the word MENU will appear. With the bottom right button scroll until the word SETTINGS, press the top left key SET, scroll with the bottom right key until the word AUTOECO appears. Select SET again in the top right and with the bottom right key set OFF or ON and press OK to save the setting. Now going back to the initial menu you notice that the setting on the Mode is ECO. Therefore, using the bottom left or bottom right keys it is possible to set the temperature and the fan speed respectively, for the expulsion of hot air.

To disable the AUTO-ECO function follow the same procedure.

If the keypad of the control panel is inactive for 10 seconds the remote control automatically leaves the fan adjustment mode and does not confirm the last setting inserted.

In selecting the fan speed, it is advisable not to select very low speeds (1st or 2nd) when the stove is at maximum power as this may cause the structure to overheat.

4.8. HOT AIR VENTILATION

The Star and Ego stove are equipped with an internal fan for expulsion of heating air. It can be set to 5 different speeds at any time regardless of the whether the stove is in manual or automatic mode.

5 speeds can be selected as well as an automatic function. To select the speed, after pressing the bottom right button, press it

again to increase or decrease the fan power. In addition to 5th speed there is an additional selection called AUTO

function. This function lets you connect the fan speed to the flame power. With this option selected, the stove will independently select the fan speed based on the flame power.

This option can be simply selected by always pressing the bottom right key, scrolling through the various speeds 1-2-3-4-5. On the control panel the letter A will appear.

Example with ventilation set to AUTO:

If the flame is at power 3, the fan will automatically set to speed 3. If the flame is at power 5, the fan will automatically set to speed 5, and so on.

If a timer programme is active but the user decides to start/stop the stove in advance, the command given by the user overrides the timer and is carried out. The next command from the timer is obviously disregarded.

Example: if the timer calls for the stove to be started

up at 10:00 but the user decides to start it at 9:00, by pressing button 5 the stove will come on. At 10:00, the timer, which was to order start-up, will be disregarded.

IMPORTANT NOTE

It takes 10 to 15 minutes for the stove to start up. Take this into account when setting the start time. Likewise,

stove shutdown requires about 30 minutes, during which the heat stored up by the stove is still released into the room.

Keep this in mind for substantial fuel savings.

Once the desired programme is selected for the active day (e.g. 32 for the day MO = Monday), press the OK key in the top right and on the display the word Ma P00 will appear (where the word P00 flashes), proceed with the programming mode until the day SU=Sunday.

If for a given day of the week you do not want to set any programme, select programme 00 and continue with programming.

4.10.3. TIMER de-activation.

To de-activate the timer, access the menu again by means of button OFF.

4.11. PRE-SET WEEKLY AND DAILY PROGRAMMES

4.11.1. Weekly programmes

The weekly programmes selected by MCZ and stored in the memory of the control panel were designed to meet the needs of most users who are out of the home during working hours (factory workers, shopkeepers, office workers, shift workers) as well as those who are usually at home (homemakers, senior citizens, etc.).

Also, programming has been provided for those who use the stove in a weekend home (e.g. a home in the mountains) and want to find the home warm when they get there.

If you have even more specific needs which are not met by any of these weekly programmes, you can customize weekly programme P99 using seven different programmes for each single day of the week

4.12. PRACTICAL EXAMPLE OF DAILY PROGRAMMING

4.12.1. Setting of a daily programme

Let's look at a user who does not have regular daily hours (a free-lance worker, for example), but who generally expects to be at home at the following times:

 MONDAY  home until 10:00 and from 17:00 on  TUESDAY  home until 8:00 and from 14:00 on  WEDNESDAY  at home all day and does not wish to set any programme  THURSDAY  at home all day  FRIDAY  at home until 9:00, from 12:00 to 15:00 and from 18:00 on  SATURDAY  at home only after 18:00  SUNDAY  at home only after 14:00

Based on these times, from the table in paragraph 4.11.2 the daily programmes are selected which best suit this routine.

 MONDAY  Programme 20  TUESDAY  Programme 43  WEDNESDAY  Programme 00  THURSDAY  Programme 13  FRIDAY  Programme 34  SATURDAY  Programme 10  SUNDAY  Programme 08

To activate this type of customised setting follow the instruction in par.

4.10 page 39.

4.13. SAFETY DEVICES

The stove is fitted with the following safety devices:

 SMOKE TEMPERATURE SENSOR.

Monitors the temperature of the smoke, and gives permission for start-up or shuts the stove down when the smoke temperature falls below the preset value.

 PELLET HOPPER TEMPERATURE SENSOR.

If the temperature exceeds the preset safety level, it immediately shuts down the running of the stove, and has to be reset, after the stove has cooled, before the it will restart.

 ELECTRICAL SAFETY

The stove is protected against violent surges of current by the main fuse, which is located on the control panel at the rear of the stove. Other fuses to protect the electronic boards are to be found on the boards themselves.

 FAILURE OF THE SMOKE EXTRACTION FAN

If the fan stops, the electronic board shuts off the supply of pellets in good time, and an alarm is displayed.

PELLET STOVES

Chapter 4

INSTALLATION AND USE MANUAL

Operation

Technical service - Rights reserved MCZ GROUP S.p.A. - Reproduction prohibited

TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED

It is only after eliminating the cause which gave rise to the intervention of the safety system, that it is possible to relight the stove and thus reset the automatic operation of the sensor. To understand which anomaly has occurred, consult this manual at paragraph 4.14 which explains what to do based on the alarm message the stove displays.

ATTENTION

 BREAKDOWN OF THE REDUCTION MOTOR

If the reduction motor stops, the stove continues to function until it has cooled down to the minimum level.

 TEMPORARY POWER CUT

If there is a power outage during operation, when the power comes back on the stove will go into cooling mode and then it will come back on automatically.

 FAILURE TO LIGHT

If during ignition no flame develops, the stove will go into alarm condition.

If the stove is not used as described in this instruction booklet, the manufacturer refuses to accept any responsibility for damage to persons and property that may arise. The manufacturer furthermore refuses to accept responsibility for damage to persons and property arising from the failure to observe all the rules contained in the manual and in particular:

 Failure when carrying out works of maintenance, cleaning

and repair to adopt all necessary measures and precautions

 Tampering with the safety devices.  Removing the safety devices.  Failure to connect the stove to an efficient system for the

discharge of smoke.

 Failure to check in advance that the room where the stove

is to be installed is adequately ventilated.

4.14. ALARM SIGNALLING

Should an operation problem occur, the stove enters a shutdown phase for alarm and informs the user of the type of fault that occurred using a 3 digit code that remains displayed on the control panel of the stove (and a short description of the alarm type)

The table below describes the possible alarms signalled by the stove, associated to the respective code that appears on the emergency panel, and useful suggestions to solve the problem.

5. MAINTENANCE AND CLEANING

5.1. DAILY AND WEEKLY CLEANING BY THE

USER

5.1.1. Before each lighting

Using a suitable tool clean the grate “F” of ash and any incrustation which could obstruct the passage of air.

In the case of pellet depletion, unburnt pellet in the grate could accumulate in the hopper. Always empty the residuals from the grate prior to each lighting.

For good cleaning of the grate, pull it completely out of its housing and thoroughly clean the grate and holes on the bottom. If you use goodquality pellets, you will normally only need to use a paintbrush to restore the perfect condition of the component. For tough incrustations, use the steel tool provided with the stove.

5.1.2. Check every 2/3 days

Clean and empty the ash drawer, watching out for hot ash. Only if the ash is completely cold, it is possible to use a vacuum

cleaner to remove it. Use a drum-type vacuum cleaner that is suitable for picking up particles of a certain size.

Experience, and the quality of the pellets used, will determine the frequency of cleaning.

It is however advisable not to let it exceed 2 or 3 days. Once the operation is finished, reinsert the ash drawer below the grate

making sure it is well inserted

5.2.3. Shutting the stove down (end of season)

At the end of season, before shutting down the stove, we recommend completely removing pellets from the hopper with the use of a vacuum cleaner with an extension.

During periods of disuse, the stove must be unplugged and placed in a dry place protected from the elements. For greater safety, especially if there are children around, we recommend removing the supply cable from the rear of the stove.

Upon re-start, when pressing the main switch (located on the back of the stove) does not make the control panel display light up, it could mean that the service fuse needs replacing.

On the rear of the stove there is a fuse holding compartment which is located underneath the supply socket. Use a screwdriver to open the fuse-holder compartment and if necessary replace them (3.15 AT delayed)

5.2.4. Check of internal components

We recommend that an annual maintenance service is carried out, preferably under a programmed service contract. The essential part of this service is a visual and functional check on the internal components:

The following is a summary of the checks and/or maintenance tasks which are indispensable for the correct operation of the stove.
