PELLET STOVES Chapter 2

INSTALLATION AND USE MANUAL

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 5.3 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 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.

The pellets must be produced from pure wood which has not been treated chemically.

The standards DIN 51731 and ONORM M 7135 certify a high-quality pellet with the following characteristics:

9 Calorific power: 5.3 kW/kg 9 Density: 700 kg/m3 9 Water content: max 8% of weight 9 Percentage of ashes: max 1% of weight 9 Diameter: 6 – 6.5mm 9 Length: max 30mm 9 Contents: 100% untreated wood, with no added bonding

substances (bark percentage 5% max)

9 Packaging: in sacks made from ecologically compatible or

biologically decomposing material

Fuel pellets

PELLET STOVES Chapter 2

INSTALLATION AND USE MANUAL

MCZ strongly recommends using certified fuel in its stoves.

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.

2.2. PRECAUTIONS FOR INSTALLATION

IMPORTANT! Installation and assembly of the stove must be

carried out by qualified personnel.

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 (EN73-23)

• 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.

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.

page

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 m

/h must be

PELLET STOVES Chapter 2

INSTALLATION AND USE MANUAL

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 m 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 cm

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.

It is not permissible to install the stove in bedrooms, bathrooms or showers, 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 walls are not flammable, position the stove with a clearance to the rear of at least 10 cm.

For flammable walls, keep a minimum distance of 20 cm at the rear, 50 cm on the sides and 150 cm at the front.

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.

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

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.

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

Theoretical notions for installation Technical service - Rights reserved MCZ S.p.A. - Reproduction prohibited

PELLET STOVES Chapter 2

INSTALLATION AND USE MANUAL

page

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 REV.

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.

Rear view of a pellet stove

1) Combustion air intake

2) Smoke outlet

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.

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.

2 - 3 mt. MAX

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

IMPORTANT! All 90 degree changes of direction in the flue pipe

must be fitted with suitable tee connectors to allow

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.

This type of connection ensures the evacuation of the fumes even in the event of a temporary power cut.

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.

This type of connection ensures the evacuation of the fumes even in the event of a temporary power cut.

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.

Least favourable points

WIND

High-pressure

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).

IMPORTANT! The operation of the pellet stove is noticeabl

sensitive to the conformation and position of the flue which is adopted.

Hazardous conditions can only be overcome by suitable setting-up of the stove carried out by qualified MCZ personnel.

3.2. PREPARATION AND UNPACK ING

Polar and Nova stoves are delivered in two packages:

9 The first contains the stove (Fig. 1) 9 The second contains the ceramic cladding. (Fig. 2)

The Athos stove is delivered only with the packaging in fig. 1. Open the packaging, take off the bands, remove the stove unit from

the pallet and position it in the chosen location, taking care that its position 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 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.

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) .

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 (fig. 4).

3.3. CONNECTIONS OF HOT AIR DUCTS FOR

POLAR/NOVA/ATHOS MULTIAIR MODEL

Deflector

page

Once the stove is in position, you can begin installation of the hot air ducts.

First of all, select the amount of hot air that you want to come out of the front and the back of the stove.

This simple operation is possible by adjusting the mechanical deflector located on the upper part of the stove, under the ceramic top,

Figure 3)

( the opening, the more air will be directed to the front part and less to the back, and vice versa.

For further clarity,

to the desired position, using the provided hook. The greater

Figure 4

shows the partitioning of hot air between the two outlets (front and rear) at maximum ventilation power and taking one duct into account.

Do not adjust the upper deflector when the stove is in operation or if you are not wearing protective gloves: DANGER OF BURNS. Outlet air normally has an average temperature of ≥ 70°C

NEVER COMPLETELY CLOSE THE REAR AIR OUTLET!!! You should not send all of the hot air to the front

part of the stove. The high amount of air in circulation would cause noisy turbulence in the air exchanger of stove, and it would also cause the structure to overheat substantially. You can however completely close the front outlet (deflector) and send all the air to the rear outlet.

Once you have adjusted the deflector, connect the rear flange for hot air outlet

(Figure 4)

to ducts and nozzles. You can use special fittings from MCZ that divert the flow into several nozzles and which may be cemented into the wall. The rear hot air outlet has a diameter of 100 mm. Therefore, you can use pipes of the same or slightly smaller diameter (80 mm) to be cemented into the air spaces of the home. A pipe which is inserted in the wall must be properly insulated so that it does not lose heat and so that air outlet is silent.

You should use ducts of the same length so that the air is evenly distributed. Otherwise, the air will tend to flow through the shortest or least twisted ducts

Shown here (

Figures 5 and 6

) is a simple example of ducting, seen both

from in front of and in back of the stove For better air circulation in the room, it is advisable also to connect with

the exterior the rear air inlet flange (

Figure 6 – A

). This connection is not required if the room where the product is installed is sufficiently ventilated.

4.1. PRE-LIGHTING WARNINGS

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.

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 1 During subsequent use, you will be able to make use of all available heating power (e.g. 4 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.

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.

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.

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.

4.3. LOADING THE PELLETS

page

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

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.

4.4.2. General characteristics of the LCD remote control

The stoves which are equipped with the ACTIVE SYSTEM combustion control device are controlled mainly by a remote control or in an emergency from the small rear panel.

The LCD remote control lets you take full advantage of all the features of the stove, adjust all operating parameters, set the timer, but most of all to continuously monitor the room temperature so as to suitable control the stove's operation.

In fact, the temperature sensor is built right into the remote control. This allows more precise measurement of the temperature in the room to be heated wherever the user wants, and without the inconvenience and limitations of wired thermostats.

The remote control has back-lighting which is activated by simply pressing a key.

Keep the remote control away from direct heat and water.

It is advisable to keep it out of the reach of children. The remote control should always be kept near the

stove (within a radius of 5 m) so that correct room temperature values are transmitted. If the stove does not receive any input from the remote control for at least three hours, it will start emitting periodic acoustic signals to inform the user that the remote control is too far away or that the batteries are dead. The display of the emergency panel will show the alarm A10. In this alarm condition, the stove will continue working. To eliminate the alarm, just move the remote control nearer to restore normal operating conditions.

4.4.3. Type of batteries and replacement

The batteries are housed in the lower part of the device at the support base.

Operation requires 3 AAA batteries 1.5 V. Via icon no. 4, the remote control informs the user when the batteries

are nearly dead. If the icon showing an empty battery appears, it means that the batteries are nearly dead and that the remote control is about to shut off.

If the remote control shuts off due to dead batteries, the stove can only be controlled from the rear emergency panel (see paragraph 4.5). Only a few essential functions remain active during emergency operation: power on, power off and manual adjustment of three levels of power.

The batteries provided have a limited lifespan to allow first lighting of the stove and for the user to learn how to use the device.

It is advisable to replace the batteries after the first lighting. It is also advisable to keep a stock of reserve batteries in the home.

When replacing the batteries, ensure correct polarity by observing the symbols on the internal compartment of the remote control.

The stove -- and as a result the display of the remote control -- is turned on and off by pressing key 3 on the remote control for 2

seconds.

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 3, the cooling-off procedure begins. This includes interruption fuel loading, cleaning of the grate 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 and where it is located.

page

4.7.2. Note on first ignition

The first attempt at ignition may not be successful, since the feeder screw is empty and it is not always able to fill the grate with required amount of pellets in time to ensure normal ignition

CANCEL THE ALARM CONDITION FROM THE EMERGENCY PANEL (see paragraph 4.16), REMOVE PELLETS IN THE GRATE AND REPEAT LIGHTING

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.

REMOVE THE PELLETS FROM THE BURNER AND CONTACT AN AUTHORISED MCZ TECHNICIAN.

4.8. OPERATING MODE

SOLAR-GEA stoves have two operating modes: MANUAL and AUTOMATIC.

4.8.1. 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 message MAN on the display of the remote control (icon 1)

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 message AUTO on the display of the remote control (icon 1)

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

To choose the mode, press button 4

At each lighting, the stove automatically sets to the operating mode that it was in the last time it shut down.

paragraph 4.8.4.)

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

4.8.2. Manual mode

PELLET STOVES Chapter 4

INSTALLATION AND USE MANUAL

page

In this mode you can only vary the thermal power provided by choosing the flame power.

Button 4 of the remote control is used to select MANUAL mode. On the display this is indicated by the message MAN and the flame symbol. In this mode, button 5 is used to adjust the 5 heating powers of the stove.

Press the upper part of button 5 to increase power. Press the lower part to decrease power. This variation is indicated by the bars located above the flame symbol. Upon reaching the 5th power level, the message MAX appears under the flame symbol. This indicates that maximum performance of the stove has been reached.

In this operating mode, the flame symbol is completely on.

4.8.2.1.

Changing from manual to automatic mode

To change from MANUAL to AUTOMATIC operating mode, just press the button no. 4 . The message MAN will go off and the message AUTO will come on. The flame power indicators and the flame icon will disappear. The numerals will come on for setting the desired temperature (icon 8)

4.8.3. 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.

Press button 4 on the remote control to select AUTOMATIC mode. This will be shown on the display by the message AUTO. In this mode, by pressing button 5, only the desired room temperature is adjusted.

Press the upper part of button 5 to increase the selected temperature. Press the lower part to decrease the temperature. The desired temperature is indicated by the figures in icon no. 8

The remote control regulates the operation of the stove by constantly comparing the room temperature (indicated at upper right on the display and specifically the larger figures with the cassette symbol near them) with the temperature set by the user.

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.

Room temperature is measured by the remote control via a sensor inside of it. Therefore, the stove will always attempt to reach the temperature based on the measurements of the remote control sensor.

Thanks to this characteristic, the remote control can be considered a mobile external thermostat, with a range of about 5 m (with batteries charged)

Since the remote control acts as an external thermostat, it is necessary to for the remote control and the stove to communicate with each other. It is therefore suggested to keep it in the same room as the stove, within a radius of 8 metres, but not so close that it will be affected by the heat from the stove.

MAX

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

PELLET STOVES Chapter 4

INSTALLATION AND USE MANUAL

page

It is advisable to keep the remote control in the room where the stove is installed so that the stove and remote control can communicate with each other.

If the remote control is moved out of range from the stove, the stove will no longer have any temperature feedback. It will therefore continue operating in the same manner as was set by the last transmission from the remote control.

4.8.3.1.

Changing from automatic to manual mode

To change from MANUAL to AUTOMATIC mode, press button 4 so that the remote control display shows the message MAN and the bars for the adjustment of flame power.

4.8.4. Automatic mode with ECO-STOP

This mode changes stove operation in automatic mode. Upon reaching the temperature set by the user, the stove goes to power 1 for a short period of time. Then, if the temperature remains constant and above the set temperature, it shuts down. The stove comes back on automatically only when the room requires heat again, but not before a period of time has passed for the stove to cool off. This option is advisable only if the stove works in highly insulated rooms or where there is low heat dispersion over time.

Example of operation in ECOSTOP mode

If the room temperature detected by the sensor of the remote control is 15°C and the set temperature is 20°C, the stove will follow a preestablished ramp up to the 5

power. Once 20°C is reached, it goes into standby mode. When the room temperature drops below the value set on the remote control (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 sensor in the remote control 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 3 for a few seconds and then pressing the same button to re-light the stove.

The “ECO STOP” mode does not need to be reset as it remains in memory from the last use.

4.8.4.1.

Activation /de-activation of ECO-STOP mode

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

This operation can be selected whether your are in manual or automatic mode by pressing and holding button 4 for 5 seconds.

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

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

4.9. HOT AIR VENTILATION

The Solar and Gea 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. To access the fan setting menu, press the button MENU 6 once and the icon for ventilation will come on completely. In fact, normally only the border of the symbol appears, since to access adjustment it is necessary to access the corresponding menu. 5 speeds can be selected as well as an automatic function. To select the speed, after pressing button 6, press button 5 up or down to increase or decrease ventilation power. Variation of ventilation can be seen by the number of bars above the fan symbol which will increase or decrease as a result. 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 selected simply by again pressing the up arrow button of button 5 once you are at the 5th ventilation speed. The display of the remote control will show the message AUTO under the fan symbol.

Example with ventilation set to AUTO:

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

If the keypad is not touched for 7 seconds, the remote control will automatically exit fan setting mode and will confirm the last inserted setting.

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.

AUTO

page

4.10. SLEEP FUNCTION

The purpose of this function is to make it faster to select a programmed shutdown, without the need to programme the stove's internal timer. To explain the SLEEP function in simple terms, it might be said that it allows the user to set a countdown starting from a minimum of 15 minutes up to a maximum of 8 hours, after which the stove will shut off. To set the function, press the MENU button 6 twice so that the icon comes on completely. Where the time is normally shown, 00:00 appears and it is possible to choose the amount of time using button 5. Press the up arrow to increase the time in steps of 15 minutes. Press the arrow down to decrease the time in steps of 15 minutes. To confirm, press key 6 again or wait 7 seconds.

After returning to normal operation, instead of showing the current time, the display will show the countdown of time remaining to shutdown.

INSTALLATION AND USE MANUAL

If the keypad is not touched for 7 seconds, the remote control will automatically exit timer setting mode and will confirm the last inserted setting.

Immediately after choosing the desired timer programme and confirming it with key 6, you will exit the setting the menu and the timer icon will remain on the display of the remote control with this format:

If this icon remains on the display, it means that a timer programme is active that includes start-ups and shutdowns over the course of a day or week.

ATTENTION!

If the timer function is active, the icon any operating screen

¥ will be on in

The TIMER function can be activated/deactivated whether the stove is on or off.

SETTING OF A PERSONALIZED PROGRAMME

If one of the pre-set weekly programmes does not suit the heating needs for your home, you can choose and combine various daily programmes included in the memory of the remote control to create a personalized weekly programme (called P99).

50 daily programmes can be selected , and you can select a different programme for each day of the week.

To activate this option, proceed as described above for setting a weekly programme, but instead of selecting one of the programmes contained in the table of the weekly programmes (from P01 to P10) select the programme P99.

Once you have selected programme P99 press push button 4 to enter daily programming mode. The first day of the week will start flashing (MO = Monday).

Use key 5 to scroll the programmes from 01 to 50 and select the desired one, after consulting the table in

paragraph 4.12.

When you carry out this type of programming, you will notice that the 24 h icon also lights up to show that daily rather than weekly programming is being performed.

Once the desired programme has been selected for the active day (E.g.: 32 for the day MO = Monday), again pres button 4 to proceed with programming of the day TU = Tuesday). Notice that as soon as the day MO = Monday is confirmed, under MO a dash appears to indicate that a daily programme is active for that day.

As soon as you confirm the programme for one day of the week and go to the next day, the remote control will make selection faster by proposing the last set programme (in this example 32) but with button 5 you can change it with another.

Proceed with this 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. Notice that under that day there is no dash.

INSTALLATION AND USE MANUAL

Upon completion of programming, press button 6 or wait 30 seconds and the remote control will automatically exit the menu,

confirming the selections you have made.

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, and another 10 to 15 minutes before sufficiently hot air comes out.

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 released into the room. Keep this in mind for substantial fuel savings.

4.12. PRE-SET WEEKLY AND DAILY PROGRAMMES

4.12.1. Weekly programmes

The weekly programmes selected by MCZ and stored in the memory of the remote control 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

press button 6 several times until the clock icon is completely lit.

PHASE 3 SUMMARY

PROGRAM

Confirm the selection by pressing button 6 or wait 30 seconds. The programme is confirmed, the clock icon goes off, only the borders remain visible, and the LED's that indicated the selected programme go off.

Press button 5 up to select programme P07 which was previously selected.

1. Press button 6 until the clock icon appears

2. Select the programme with button 5

3. Confirm the programme with button 6 or wait 30 seconds, after which the remote control will automatically confirm the selection made and will exit programming.

4. The empty timer icon will remain visible. This means that the programme is set and that from that moment the stove will start and stop on its own.

PROGRAM

4.13.2. 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 Î home until 10:00 and from 17:00 on

• TUESDAY Î home until 8:00 and from 14:00 on

• WEDNESDAY Î at home all day and does not wish to set any programme

• THURSDAY Î at home all day

• FRIDAY Î at home until 9:00, from 12:00 to 15:00 and from 18:00 on

• SATURDAY Î at home only after 18:00

• SUNDAY Î at home only after 14:00

Upon completion of programming of all days, when you come to SU=Sunday, press button 6 to exit programming. You can also wait 30 seconds and the remote control will automatically exit programming, confirming all settings made. For a quick check of programming, look to see whether there are dashes under the symbols of the week, or you can go back to programming with button 6, re-select programme P99 with key 5, and then, still using button 6, scroll all the days of the week to check which programme has been set.

4.16. SAFETY DEVICES

The stove is fitted with the following safety devices:

• PRESSURE SWITCH

Monitors depression in the smoke duct. It is designed to shut down the pellet feed screw in the event of an obstructed flue or significant back-pressure (from the wind).

• 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 manually, 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.

• BREAKDOWN OF THE REDUCTION MOTOR

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

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

PELLET STOVES Chapter 4

• TEMPORARY POWER OUTAGE

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.

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 4.17 which explains what to do based on the alarm message the stove displays.

INSTALLATION AND USE MANUAL

page

ATTENTION

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.

4.17. ALARM SIGNALLING

If there is an operating anomaly, the stove goes into alarm shutdown mode and informs the user of the type of problem that has occurred via a 3-figure code displayed on the rear emergency panel.

The alarm is permanently signalled by the corresponding 3-figure code, by a flashing red light on the emergency panel, and, for the first ten minutes of the alarm, by a periodic acoustic signal. To take the stove out of alarm conditions and restore its normal operation, read the instructions in the next two paragraphs.

The following table summarizes the possible alarms which the stove may signal and corresponding code which appears on the emergency panel.

4.18. Exiting alarm condition

If there is an alarm, to restore normal operation of the stove you will need to follow the procedure outlined below:

• Place selector D of the rear emergency panel in the OFF position for a few seconds until the 3-figure code that identifies the type of alarm disappears. The following operation will also stop the flashing of the red LED and the acoustic alarm signal.

• Place selector D back in the REMOTE position, so that the stove can again be managed by the remote control.

• Turn the remote control off and back on again if you want to restart the stove.

Only in the event of defect A12 (no communication between remote control and stove), the stove will remain on with the most recently set mode. It will automatically exit alarm mode as soon as it receives a signal from the remote control.

4.18.1. Mechanical shutdown of the stove

The following things can cause stove shutdown:

• Overheating of the stove body

• High pressure in the outlet fumes (as read by the pressure

switch) and therefore possible obstruction of the smoke discharge system or external back-pressure.

Shutdown is signalled on the display accompanied by a beep. In this situation the shutdown cycle is automatically activated. Once this process has started, any operation which is an attempt to

reset the system is useless. The cause of the shutdown is shown on the display.

WHAT TO DO:

When the stove is cold: if the message “A03” appears, proceed as set forth in paragraph 4.17 at indication A03

If the message “A05” appears, check that the ENTIRE smoke duct, including the combustion chamber, is clean and free of any obstruction. (it is recommended that this operation be conducted by a specialist MCZ technician).

Only after the cause of the blockage has been permanently eliminated can a fresh attempt to relight the stove be made.

5. MAINTENANCE AND CLEANING

ATTENTION! All cleaning of all parts must be carried out with the

stove completely cold and unplugged.

The stove does not need much maintenance if used with certified quality pellets. The necessity for maintenance increases with use and depending on the performance requested of it.

page

5.1. DAILY AND WEEKLY CLEANING

5.1.1. Before each lighting

Clean the grate of ash and any incrustation which could obstruct the passage of air.

REMEMBER THAT ONLY A CLEAN, NEAT GRATE CAN ENSURE PROPER OPERATION OF YOUR PELLET STOVE.

A simple visual check, carried out daily, will reveal whether the grate is in good working order.

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. When the job is completed, re-close the ash drawers, making sure that

they are properly shut.

5.1.3. Cleaning the glass

For cleaning the ceramic glass, the use of a dry brush is recommended, or if it is very dirty, the special spray detergent, applying a small quantity then cleaning with a cloth.

ATTENTION! Do not spray the cleaning product on the painted

parts or on the gaskets of the fire door (ceramic fibre cord)

PELLET STOVES Chapter 5

INSTALLATION AND USE MANUAL

5.1.4. Cleaning of the air filter

At the lower part of the stove, where there is the inlet pipe for combustion air Ø 5 cm, at the time of installation of the stove a metal mesh air filter must be inserted to prevent dirt from getting into the motor body and internal sensor.

It is advisable to check every 15/20 days whether the filter is clean. Remove lint or any other material which may have been trapped by the filter.

Checking and cleaning will be required more frequently if there are pets in the home.

For cleaning, just turn the knob that holds the filter on the air intake pipe and remove the filter by turning in the direction indicated by the arrow. Clean it with a brush, damp cloth or compressed air.

The filter is made of metallic mesh. It is soft and malleable to the touch. Therefore, when cleaning it, be careful not to crush it or damage it in any other way. If it is broken it must be replaced

ATTENTION! Never operate the stove without the air filter. MCZ

shall not be held liable for damage to internal components if this instruction is not followed.

( ash and soot which has built up in the heat exchanger and in the smoke extraction fan.

Clean the smoke discharge system, especially in the area of the tee connectors and of any horizontal stretches of pipe.

For information refer to a chimney sweep.

Check the seal of the ceramic fibre gaskets on the door of the stove. If necessary order new gaskets from your dealer as replacements. At the end of the season it is necessary to clean the compartment

under the grate and the heat exchanger inside it. This general cleaning should be carried out at the end of the season in

order to facilitate the general removal of all residues of combustion, without waiting too long, because with time and humidity these residues can become compacted.

Using a stiff rod or a bottle brush, scrape the inner walls of

PELLET STOVES Chapter 5

INSTALLATION AND USE MANUAL

ATTENTION: The frequency with which the smoke discharge

system is cleaned should be determined based on the type of use that is made of the stove and the type of installation.

MCZ suggests relying on an authorized service centre for end-of-season cleaning and maintenance, who will carry out all of the previously mentioned work and make a general check of the stove's components.

5.2.2. 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)

page

5.2.3. Check of internal components

ATTENTION! The check of the internal electro-mechanical

components must be carried out only by qualified personnel with technical knowledge of electricity and combustion.

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.
