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 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.

Fuel pellets

Chapter 2

page

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

9 Calorific power: 4.9 kW/kg 9 Water content: max 10% of weight 9 Percentage of ashes: max 0,5% of weight 9 Diameter: 5 – 6 mm 9 Length: max 30 mm 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

15 Kg sack of fuel

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

IMPORTANTE! THE INSTALLATION AND ASSEMBLY MUST BE

CARRIED OUT BY QUALIFIED PERSONNEL. All local regulations, including those that refer to

national and European regulations, must be observed at the time of installation of the unit

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

The site must be:

Chapter 2

page

x capable of providing the environmental conditions for operation x equipped with power supply 230V 50 Hz (EN73-23) x capable of taking an adequate system for smoke discharge x provided with external ventilation x provided with an earth connection complying with CEI 64-8

IMPORTANT!

x THE PRODUCT MUST BE CONNECTED TO AN

INTERNAL OR EXTERNAL FLUE PIPE IN COMPLIANCE WITH CURRENT STANDARDS.

x The product must be connected to a flue pipe or

other vertical smoke stack that can discharge smoke at the highest point of the house.

x Smoke is generated from burning wood and,

therefore, may dirty adjacent or nearby walls. Also take care because the fumes are very hot but almost invisible, and can cause burns on contact.

x Before positioning the unit, a hole must be made

for the passage of the smoke pipe, and another for the intake of air from outside.

x The electrical plug must be positioned where it is

always accessible. Otherwise, during installation, provide suitable devices for disconnection for the power supply network in compliance with standards on electrical systems

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

2.3. OPERATING AREA

INSTALLATION AND USE MANUAL

Chapter 2

page

For proper operation the unit should be placed where air can flow that is necessary for pellet combustion (this requires about 40 m

/h) in accordance with the standard for installation and current national standards.

The volume of the room must not be less than 50 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.

Air can also be taken from adjacent rooms as long as they are equipped with outdoor air vents and are not bedrooms or bathrooms or rooms where fire hazards exist such as garages, wood sheds or flammable material warehouses, strictly observing that set forth by the norms in force.

It is not permissible to install 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.

Example of realization of air intake

200 cm

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

1500 cm

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: x communicate directly with the room where the stove is installed

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

Example of installation of PowerTherm

INSTALLATION AND USE MANUAL

x be protected by a grille, metal mesh or suitable guard, as long as

this does not reduce the area below the minimum.

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

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.

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.

Chapter 2

Connection of smoke discharge pipe

page

IMPORTANT!

x 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)

x 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.

x 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

x IT IS ALSO ADVISABLE NOT TO EXCEED 6

METRES IN LENGTH WITH THE PIPE Ø 80 mm

x THE TUBE Ø 80 mm IS NEEDED ONLY TO

CONNECT THE FLUE PIPE AND CANNOT ITSELF BE CONSIDERED AS A FLUE PIPE. The flue pipe has the following characteristics described in subsequent paragraphs

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.

2.8. 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.

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.

E.g. Downdraft at 45° of 8m/sec. Overpressure of 17 Pa

E.g. Crosswind 2: 8 m/sec Depression of 30Pa

Chapter 2

page

Least favourable points

Most favourable position

WIND

High-pressure

Low-pressure zone

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

Chapter 3

page

The unit is delivered in a single package. Open the packaging (1), remove the tie (2), remove the protective

polystyrene and the box (3) located above the unit. The pipe and the loading flap are packed in the box together with the components for forced ventilation. Lastly, remove the unit from the pallet by unscrewing the two screws which lock it in place and place it in the chosen location making sure that this conforms to that foreseen.

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) .

3.3. ASSEMBLING THE UNIT ONTO THE MASONRY BASE

Place the unit onto the masonry base and verify that the unit is perfectly level to ensure that it works properly.

You must anchor the unit to the base so that, during annual maintenance by an authorized technician, the combustion chamber may be removed from its housing by means of the two extensible guides.

In this situation, the centre of balance of the unit moves forward significantly. If the product has not been anchored to the base, it may lose stability.

To attach the unit to the base, use expansion plugs and 6 o 8 mm ("Fischer” type or similar)

Fixing the unit to the base is obligatory. Build the base so that the "fischer" plugs have

sufficient grip. MCZ shall not be held liable for damage to persons or

things if this warning is ignored.

3.4. INSTALLING THE LEG KIT (OPTIONAL) AND FASTENING THE UNIT TO THE FLOOR

The kit is delivered dismantled in one pack; remove the protective nylon being careful not to throw away the small bags with screws in supplied for assembly.

The first operation to be carried out is that of assembling the 2 prewelded side element with the 4 crosspieces supplied using the selfdrilling hexagon headed bolts. The crosspieces must be attached

using all of the screws provided.

The second operation is that of choosing at which height to attach the unit support legs.

The legs have two holes at three different heights. The support structure has two holes that coincide with those on the legs.

The choice of holes determines the height of the compensation frame above the ground.

If you use the first holes on the legs starting from the top, the height of the frame will be 700 mm. If you use the middle holes, the height will be 600 mm. If you use the lowest holes, the height will be 500 mm (see figure)

Once you have selected the holes and the height, use the bolts and nuts to firmly attach the legs.

The legs must be attached using all of the screws provided.

Place the unit onto the frame and lock it in place using all the cross head screws supplied.

Once the kit has been assembled, precisely define the final position for the unit and adjust the level using the adjustable feet.

Adjust the feet as follows:

x Turn the feet clockwise to lower the unit x Turn the feet counter-clockwise to raise the unit

After adjusting the feet, anchor the unit to the floor with the brackets that were previously installed on the feet.

You must anchor the unit to the floor because during annual maintenance by an authorized technician, the combustion chamber may be removed from its seat via the two extensible guides.

In this situation, the centre of balance of the unit moves forward significantly. If the product has not been anchored to the floor, it may lose stability.

To attach the legs to the floor, use expansion plugs and 6 or 8 mm screws(“Fischer” type or similar)

The unit must be attached to the ground. MCZ shall not be held liable for damage to persons or

things if this warning is disregarded.

You must

install the ventilation nozzles that are provided standard with the product, or nozzles that ensure the same operation and the same air passage cross section (see MCZ accessories).

MCZ shall not be held liable for any damage to the structure or electrical components due to failure to comply with this instruction.

Because of the high power of the PowerTherm, the structure reaches high temperatures. Therefore, continuous and efficient ventilation must always be ensured inside the cladding.

Besides ensuring perfect product operation, this action makes it possible to recover part of the heat from the structure, which would be wasted if it were left inside the cladding.

For better understanding of the number, size and function of the ventilation nozzles to be installed on the cladding, the following are some possible installation configurations with the relative nozzles.

3.18. DIAGRAM FOR MAKING HOLES ON CLADDING

Opening/closing pellet door

The diagram hereunder is relative to the three positions of the legs Kit mentioned in section 3.4.

When installed on a masonry base as foreseen by section 3.3, measure the distance between the floor and lower edge of the counter frame. This measurement is our value “K”. Compare the measured "K" with those shown in the table and choose the one nearest to that measurement. To obtain new measurements “C, D, E” , it is sufficient to add the difference between the measured "k” and that in table (ß), to measurements in the respective line.

E.G.: measured K= 630mm (the K nearest to our value is 600 mm) -> ß= 630-600= 30mm C= 1377+ ß= 1407 mm ; D= 1162+ ß= 1192 mm ; E= 617+ ß= 647 mm

INSTALLATION AND USE MANUAL

4. OPERATION

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. 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.

Do not remain near the product 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 structure will be subject to expansion and contraction during the lighting and cooling down stages, 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.

a-2a-3a

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.

This avoids damages to welds and the steel structure.

a-5a

), but remember not to keep the stove

page

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!

Try to get familiar with commands given from the control panel or remote control.

Try to memorize the messages that the display of the remote control provides.

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. Open the door and remove any components which might burn from the

firebox and from the glass (various instructions and adhesive labels). Check that the grate is positioned correctly and rests firmly on the

base, and that the fire door closes correctly.

INSTALLATION AND USE MANUAL

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

Fuel is loaded through the front or side door to be installed on the cladding. It allows access to the fuel filling chute.

To make fuel loading easier, perform the following steps:

x Open the door and pour half of the sack's contents directly

into the chute, using the scoop provided (A)

x Using the provided tool (B), push any pellets that may have

accumulated in the chute towards the hopper, and distribute them evenly in the hopper.

x Then dump the second half of the sack in the same way

Carefully pour the pellets, not too quickly, so that the pellets do not bounce out of the hopper and spill over into the cladding

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

4.4. LCD REMOTE CONTROL

4.4.1. General characteristics of the LCD remote control

The stoves are mainly controlled by the remote control or, in case of emergency, from the small rear panel.

The radio frequency LCD remote control lets you take full advantage of all the features of the stove, adjust all of the operating parameters, set the timer, but most of all 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 bright back-lighting which is activated by simply pressing a key.

page

Position of the room temperature probe

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.

4.4.4. 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/ventilation.

The batteries provided may have a limited lifespan.

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

4.7.1. Turning on/off from the remote control

page

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 1

second. 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.

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 (A02) CONDITION FROM THE EMERGENCY PANEL (see paragraph 4.17), 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.

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.

INSTALLATION AND USE MANUAL

4.8.2. Manual mode

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.

page

4.8.2.1.

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)

Changing from manual to automatic mode

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).

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

PELLET STOVES Chapter 4

INSTALLATION AND USE MANUAL

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.

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.

page

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.

4.9. HOT AIR VENTILATION

In this version the unit is equipped with two ventilators which guide the hot air frontally. For convenience we will call “ventilator1” the one which expels the air on the front right and “ventilator 2” the one with front left outlet.

The adjustment of the two fans summarised in the table below is independent and is set using the remote control.

Type Fan speed

Fan 1 0 1 2 3 4 5

Fan 2 0 1 2 3 4 5

35 POSSIBLE COMBINATIONS

THE COMBINATION 0-0 IS NOT ADMITTED

Activate the ventilation icon using the key (6) of the remote control. Number 1 will appear above the bars symbol (17) indicating the

ventilation speed. This indicates that the “fan 1” is being programmed. Adjust the intensity using the button (5). Press the key (6). Number 2 will appear above the bars, indicating that the “fan 2” is being programmed. Adjust the intensity using the button (5).

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 1, the fan will automatically set to power 1, 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.

If a low ventilation is set, the stove power is selflimited to avoid the overheating of the structure and of the air coming out of the room fans.

PROGRAM

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.

The setting defined on the personalised programme is stored in the memory even if the batteries of the remote control are removed and replaced.

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 still 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 ten weekly programmes, you can customise weekly programme P99 using one of the 60 different programmes for each single day of the week

4.13. PRACTICAL EXAMPLE OF WEEKLY/DAILY PROGRAMMING

4.13.1. Setting of a weekly programme

Let's take the example of a normal factory or office worker who starts work at 8:00, comes home for lunch at 12:30 and goes back to work from 14:00 until 18:00.

Among the programmes in the remote control, there is one which best suits the times when the user is in the home. It is P07 (

paragraph 4.12.1

). This is how to set it:

PHASE 1 PHASE 2

see table in

page

PROGRAM

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.

PROGRAM

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.

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:

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

Based on these times, from the table in paragraph 4.12.2 the daily programmes are selected which best suit this routine.

PROGRAM

For WE=Wednesday, no programme is desired. Therefore, as in the other cases, it is enough to use button 5 to select programme 00 and then confirm the selection with button 4.

PHASE 9 CONCLUSION

To conclude programming for the remaining days of Thursday, Friday, Saturday and Sunday, proceed as for Monday, Tuesday and Wednesday. The only difference is the programme number which is selected with button 5.

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 4, and then, still using button 6, scroll all the days of the week to check which programme has been set.

24 h

PROGRAM

Since no programme has been set for WE= Wednesday (it was decided to select 00), you will note that programming moves to TH= Thursday but that under the symbol WE=Wednesday there is no dash. This means that for that day, no timer programme has been set.

4.14. INSERTION OF KEYPAD LOCK

The remote control is equipped with a function that makes it possible to lock the keypad, so that keys cannot be pressed accidentally or the remote control cannot be used by a child.

This lock is activated simply by press button 6 for 3 seconds. After that time, a lock symbol will appear at the upper left of the

display to confirm that the keys are locked. To deactivate the lock, repeat the operation described above.

4.16. SAFETY DEVICES

The stove is fitted with the following safety devices:

x 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.

x 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.

x 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.

x 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.

x BREAKDOWN OF THE REDUCTION MOTOR

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

x 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.

x FAILURE TO LIGHT

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

INSTALLATION AND USE MANUAL

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.

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:

x Failure when carrying out works of maintenance,

cleaning and repair to adopt all necessary measures and precautions

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

discharge of smoke.

x Failure to check in advance that the room where the

stove is to be installed is adequately ventilated.

4.18.1. Mechanical shutdown of the stove

The following things can cause stove shutdown:

x Overheating of the stove body (“A03”) x Overheating of the smoke (“A04”) x During the function of the stove, an uncontrolled air intake

occurred in the combustion chamber or an obstruction in the flue pipe (“A07”)

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:

If “A03” appears: the structure is too hot because the product has been operating for too long at maximum power, or it is poorly ventilated, or the air fans are faulty. When the stove is sufficiently cold, press button B on the control panel or OFF on the remote control to cancel the alarm A03. Once the alarm is cancelled it is possible to relight the stove normally

If “A04” appears: the stove will shut off automatically. Let the stove cool off for a few minutes, then re-light it.

Control the exhaust of the smoke and check the type of pellet being used. If “A07” appears: it is caused by the prolonged opening of the fire

door or by substantial air infiltration (e.g. smoke fan inspection plug missing). If not caused by these factors control and if necessary clean the smoke duct and the flue pipe. (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

structure completely cold and with the plug disconnected.

The unit 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.

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.

THE HOLES OF THE GRATE MUST ALL OBSTRUCTIONS AND INCRUSTATIONS. REMEMBER THAT ONLY A CLEAN GRATE CAN ENSURE OPTIMAL PRODUCT OPERATION.

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

BE FREE OF

Grate clean

Grate dirty

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 good quality 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 product.

5.1.2. Cleaning 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. Also remember to clean the housing pocket of the grate using an attachment.

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 finished, put the ash drawer and grate back in place. Make sure everything is in the proper position.

5.1.3. Cleaning the glass

When the glass is cold, open the fire door. Spray a small amount of a special spray detergent (see MCZ accessories) on a soft cloth preferably cotton, and clean the glass. Do not spray the product

directly onto the glass. It may drip between the glass and the steel profiles and damage the silkscreen printing.

Extraction of grate for cleaning

5.2. PERIODIC CLEANING TO BE PERFORMED BY THE USER

ATTENTION! This maintenance must be performed only by

specialized or authorized personnel. MCZ shall not be held liable for any damage to persons or things if this instruction is disregarded. MCZ reserves the right to evaluate the validity of the guarantee based on the damage caused to the product.

5.2.1. Extracting the unit

To service some devices and clean some parts, a part of the unit will need to be extracted from its seat. The mobile part is mounted on runners that allow easy movement. Before extracting it, you will need to remove the compensation frame as described in the instructions in chapter 3.15 to prevent damage to it during maintenance. For

extraction, open the fire door and remove the two front screws shown in the figure.

Once you have removed the screws, pull slightly towards you to extract the mobile part just like a normal drawer. The guides have stops that block the mobile part once it is extracted all the way out.

Chapter 5

page

THE UNIT MUST BE EXTRACTED ONLY WHEN THE STRUCTURE IS COLD. DISCONNECT THE ELECTRICAL POWER SUPPLY FIRST.

When you put the mobile part back in place, make sure to fully tighten the two screws you previously removed. If you forget to do this, the product may not work due to lack of electricity or soot leakage

5.2.2. Cleaning of the air filter

At the back of the unit, at the combustion air intake tube Ø 5 cm, there is a metallic mesh air filter. Its purpose is to keep dirt out of the motor body and the internal sensor.

This filter should be cleaned every time you extract the unit from its seat to carry out recommended maintenance in the middle of and at the end of the season.

To clean the filter, remove it in the direction of the arrow and remove dust from it using a brush, damp cloth or compressed air.

ATTENTION! THE AIR FILTER MUST BE INSTALLED. Never operate

the product without the air filter. MCZ shall not be held liable for damage to

components if this instruction is not followed.

Extraction of mobile part of unit

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

INSTALLATION AND USE MANUAL

5.2.3. Cleaning of the heat exchanger

Halfway through the winter, but especially in the spring, you will need to clean the air spaces where discharge smoke passes.

This cleaning must be done in order to remove all combustion residues before time and humidity let them harden and make them difficult to remove.

When the unit is cool, open the fire door and extract the ash drawer and grate. Then loosen the three screws located just above the fire mouth to remove the bracket that holds the internal Alutec refractory parts. Gently remove the sides and then the back.

When removing the refractory parts, be careful not to let them hit each other as they may chip or break. Put them in a safe place until it is time to re-install them.

As soon as the refractory material back is removed, you will notice that the steel back has openings where smoke normally passes. Insert a bottle brush (preferable iron) in all of the openings and scrape the walls of the fire box so that the ashes fall into the part below where the inspection panels are located.

Loosen the bolts and open the inspection panels located under the ash drawer. With a vacuum cleaner attachment, remove all the ash and soot from the heat exchanger, again using a brush and the attachment.

Put everything back in place by performing the above steps in reverse order.

Chapter 5

page

Screw for anchoring bracket that supports Alutec refractory items

5.2.4. Cleaning of smoke duct and connection

When the unit is extracted, on the left it is possible to work on the smoke intake volute (1) for cleaning and maintenance. To perform this maintenance, you will need to remove the smoke intake fan.

On the outlet of the volute there is a gasket (3) that seals the connection with the smoke connection (2). Always check the condition of this gasket and replace it as needed. The gasket can also be adjusted using a screw. You can turn the screw to increase or decrease the pressure on the connection.

At the rear of the unit, at the volute outlet, there is the smoke connection with its ash collection compartment (4). Also clean this compartment with a vacuum cleaner, inserting the attachment in the insertion hole of the volute.

Clean the smoke discharge system, especially in the area of the connectors, curves and any horizontal stretches of pipe. For information on cleaning the flue pipe, contact a professional chimney sweep.

WARNING: The frequency with which the smoke discharge

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

5.2.5. Other checks

All seal gaskets installed on components subject to maintenance (smoke intake fan, inspection panels, etc.) must be replaced when those parts are removed for maintenance. Check the seal of the gaskets on the fire door. If necessary, contact an authorized service centre to have them replaced

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.

5.2.6. Shutting the stove down (end of season)

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

In the period when the unit is out of use it must be disconnected from the electricity mains. Upon re-start, when

pressing the main switch does not cause the control panel display to light up, it could mean that the service fuse needs replacing.

On the main button there is a fuse box which is located above the power socket.

There is a fuse box on the filtered socket. Use a screwdriver to open the fuse-holder compartment and if

necessary replace them (3.15 A delayed)
