2. THEORETICAL NOTIONS FOR INSTALLATION

2.1. PELLETS

Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the working of natural dried wood. The compactness of the material comes from the lignin which is contained in the wood itself, and allows the production of pellets without the use of glues or binders.

The market offers different types of pellet with characteristics which vary depending on what mixture of woods is used. The diameter varies between 6 mm and 8 mm, with a standard length in the range 5 mm to

30 mm. Good quality pellets have a density which varies between 600 kg/m3 and 750 kg/m3, with a moisture content which varies from 5% to 8% by weight.

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

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

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

The 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:







Calorific power: 4.9 kW/kg

Water content: max 10% of weight

Percentage of ashes: max 0,5% of weight









Diameter: 5 – 6mm

Length: max 30mm

Contents: 100% untreated wood, with no added bonding substances (bark percentage 5% max)

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

PELLET STOVES


MCZ strongly recommends using certified fuel in its

stoves (DINplus e Ö-Norm M7135).

The use of fuel of inferior quality or not conforming to the specification given above compromises the running of your stove and can therefore lead to the termination of the guarantee and of the manufacturer's responsibility for the product.

MCZ pellet stoves run exclusively on pellets with a diameter of 6 mm (only for Italy) and 6-8 mm

(European countries) with lengths that go from 5 mm to 30 mm.

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 capable of taking an adequate system for smoke discharge

 provided with external ventilation provided with an earth connection complying with CE

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.

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

2.3. OPERATING AREA

PELLET STOVES


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

3

/h must be available), as laid down in the standard governing the installation and in accordance with local national standards.

The volume of the room must not be less than 30 m

3.

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

2.

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 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.

In the case of flammable walls, keep a minimum distance to the rear

(A) of 5 cm, to the side (B) 5 cm, a minimum distance from the tube to the wall (E) of 5 cm and to the front 150 cm.

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

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

Chapter 2

page

12

Example of pellet stove installation



PELLET STOVES




 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

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

1

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.

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.

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 the possibility of inspection. (see accessories for pellet stove)

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

FOR CONNECTION TO THE FLUE PIPE, NOT MORE

THAN 2-3 METRES OF HORIZONTAL PIPE MUST BE

USED AND NOT MORE THAN THREE 90° CURVES

MUST BE USED

IT IS ALSO ADVISABLE NOT TO EXCEED 6 METRES IN

LENGTH WITH THE PIPE Ø 80 mm

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.

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

2.9. OPERATING PROBLEMS CAUSED BY DRAUGHT

DEFECTS IN THE FLUE

E.g. Downdraft at 45° of

8m/sec. Overpressure of 17

Pa

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

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 noticeably 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.

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.

Position the stove without its cladding and connect it to the flue pipe.

Use the four adjustable feet (J) to get the stove correctly levelled so that the smoke outlet (S) is lined up with the connecting pipe (H) .

Once the operations for connection are complete, assemble the cladding (ceramics or steel sides).

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

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.

3.4. MAKING THE ELECTRICAL CONNECTIONS

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

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

If you do not intend to use the stove, it is advisable to keep it switched off.

PELLET STOVES


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.

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

It is recommended to provide plenty of ventilation in the room during the initial lighting, as the stove will give off a small amount of smoke or odour due to the stabilisation of the paint.

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 heating power (e.g. 4 a

-5 a

). a

-2 a

-3 a

).

During subsequent use, you will be able to make use of all available

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

Do not demand maximum heating performance immediately!

As with automobiles, a running-in period is recommended, even if only for a short period of time (4/5 hours).

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

Try to memorize the messages that the stove provides on the display.

4.2. PRE-LIGHTING CHECK

PELLET STOVES


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

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 about 10 kg.

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. CONTROL PANEL/REMOTE CONTROL DISPLAY

(accessory)

4.4.1. Control panel logic

Reported below are some useful information to understand the navigation logic and use the control panel:

 The luminosity of the control panel is switched off after about

20” seconds of the keyboard being inactive. To switch on the back lighting again just press any of the buttons on the panel.

 The first screen that appears displays the operating status of the stove (ON, OFF, LIGHTING, SHUTDOWN..) that alternates with any other settings activated (TIMER, SLEEP, AUTO ECO..)

 By pressing any of the 4 keys around the display (C D E F) you access the stove's operation settings screen (level of the flame, fan, set temperature, manual or automatic mode..). From this level the 4 keys around the display assume “dedicated” functions, i.e. they directly refer to the corresponding words that appear in the 4 corners of the display (e.g.: the word in the top right hand corner refers to the D key).

 When a setting is modified in any menu level without confirming the modification using the “OK” key and leaving the keypad inactive for 60 seconds, the first screen automatically reappears and the modifications are not saved.

 If from any menu level the on/off (B) key is briefly pressed, the display automatically returns to the first screen (stove operating status) without saving any modifications not confirmed by he “OK” key.

4.5. SETTINGS TO CARRY OUT BEFORE FIRST

LIGHTING

Once the power cord is connected to the rear part of the stove, place the switch, also on the rear, to position (I).

The lighted button of the switch will come on.

The switch located to the rear of the stove powers the system.

The stove is off and on the panel the first screen appears with the word

OFF; by pressing any key the screen with the word MENU will appear.

4.6. FIRST LIGHTING

4.6.1. ON/OFF from the control panel or remote control (if purchased)

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

During the start-up phase lasting about 15 minutes:

Pellet loading is independent of the set power

The room temperature fan only starts when temperature is reached

Once this phase ends the stove automatically enters in power

supply mode.

4.6.2. 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

Also the subsequent lightings that follow after the pellets are depleted could fail, see par. 5.4.8.

4.7. Power supply (panel display: ON)

Once the lighting phase has ended the stove goes to flame level 3 and then increases (or decreases, according to that required by the setting) power at one value per minute.

There are three methods of setting the flame during operation at full power:



Manual



Automatic



Eco stop

Then grate cleaning is added, the stove runs this automatically according to the modes described below.

4.8. OPERATING MODE

KAIKA-FACE stoves have two operating modes: MANUAL and

AUTOMATIC.

MANUAL mode allows adjusting the flame from power 1 to power 5, ignoring any ambient temperature measurements.

This mode is indicated by the word MANU on the display of the control.

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

With this mode you can also use an advanced function called AUTO-

ECO which is described later ( paragraph 5.4.2.)

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

Chapter 4

page

30

4.8.1. Manual mode

Flame power is adjustable from a minimum of 1 to maximum of 5.

The levels of power correspond to a different fuel consumption value: by setting 5 the room will be heated in less time, setting 1 the room temperature will be maintained for a longer period of time.

The peculiarity of this setting is that the flame stays at the set value regardless of room temperature.

The flame power setting is only effective after ignition and therefore in full working order.

4.8.2. Automatic mode

The AUTOMATIC working mode foresees that the desired room temperature is set on the control panel.

The probe located on the back of the stove verifies room temperature and the flame is set at power P5 until such temperature is reached.

When it is reached it automatically drops by one power per minute until it reaches P1 and stays there as long as such condition remains unchanged.

When room temperature once again drops below that set, the flame automatically rises by one power per minute up to P5 and stays there until room temperature returns as desired once again, and so on.

4.8.2.1. AUTOMATIC MODE SETTING

From the first screen with the word ON, press any key and the screen with the word MENU will appear.

With the upper left button select the AUTO function (AUTOMATIC

mode). In this mode using the bottom left button it is possible to adjust the temperature desired in the room.

By pressing button Temp the temperature rises one degree at a time

(until it reaches 35°C to then start again from 5°C). By holding the

Temp key down you enter the menu for setting the temperature using arrow keys RH and LH

4.8.2.2. Changing from manual to automatic mode

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

4.8.2.3. Cleaning the grate

Totally independently the stove proceeds with internal over-ventilation in order to prevent obstructions in the grate holes. Nonetheless this does not exonerate users from the obligation of cleaning the grate daily.

When cleaning the grate, the smoke extractor operates at maximum power for 30”.

4.9. HOT AIR VENTILATION

PELLET STOVES


The KAIKA - FACE stove is equipped with an inner fan for the expulsion of the hot heating air that can be adjusted indifferently if the stove is in manual or automatic mode.

5 speeds can be selected as well as an automatic function.

To select the speed, after pressing the bottom right button, press it again to increase or decrease the fan power.

In addition to 5th speed there is an additional selection called AUTO function. This function lets you connect the fan speed to the flame power. With this option selected, the stove will independently select the fan speed based on the flame power.

Such function allows ventilation speed to be "connected" to the flame power with a maximum of V3. When such operation is selected the stove shall independently select fan speed according to flame power up to a maximum of V3 (P1=V1; P2=V2; P3=V3; P4=V3; P5=V3) to avoid noise.

In order to prevent the structure from overheating, avoid selecting low speeds when the stove is at maximum performance.

4.10. Room sensor

The room probe (B) is located at the back of the stove; should this

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

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

ATTENTION! Once the clamp that binds the probe wire is taken off, avoid it coming into contact with the hot parts of the stove.

5.2. TIMER

This operating mode allows the programming of the start-up and shutdown of the stove in automatic mode.

Normally, the stoves have the PROGRAMMED mode deactivated.

The basic settings in PROGRAMMED mode are:



Choice of lighting/shutdown times



Choice of programme activation day

Setting the current date and time is essential for proper timer operation.

See paragraph 5.1. to learn how to set the current date and time.

5.2.1. TIMER activation and selection of a programme.

There are six settable timer programmes, for each of these the user can decide lighting and shutdown times and the days of the week on which it is active. When one or more programmes are active, the panel alternatively displays the state of stove TIMER “n” where “n” is the number relating to the activated timer programmes, separated by a dash. Example: TIMER 1 (only timer 1 programme active) or TIMER 1-4

(timer 1 and 4 programming active) or TIMER 1-2-3-4-5-6 (all timer programmes active).

EXAMPLE OF PROGRAMMING

With the stove lit or off, enter MENU, scroll to the TIMER OFF option

(or TIMER NUMBER OF THE ACTIVE TIMER/S). Prompts PROGRAMME

1 OFF, to activate it press the SET key, using the arrow key select ON and confirm with the OK key; the screen will now show

Starting time programme and shall prompt 00.00 as a starting time, change the starting time using the right arrow key and press OK to confirm. The next screen prompts the shutdown time having a time 10 minutes later than that shown for lighting: press the right arrow key to change shutdown time and confirm with the OK key.

Next the days of the week in which to activate, or not, the timer that has just been set: using the arrow key select ON or OFF and confirm with OK. If no days of the week is confirmed as active (ON), the timer programme in turn shall not be active in the status screen (see above).

5.2.2. DETAILS OF TIMER OPERATION

1. The lighting time scrolls from 00.00 (midnight) to 23.50

2. If you change the lighting time and set a value later than the shutdown time, the shutdown time automatically sifts to lighting time + 10 min. to avoid operative errors.

3. The shutdown time may be chosen between lighting time +10 min. and 00.00 (midnight).

4. If a timer programme switches the stove off at 00.00

(midnight) on one day and another programme lights it at

00.00 (midnight) of the next day: the stove remains continuously lit.

5. If the stove is lit and the timer active, it is possible to manually shutdown the stove by pressing the OFF key; the stove shuts down and shall relight automatically at the next time foreseen by the timer

6. Equally in the stove off and timer active state, press the ON key: the stove will light and shutdown at the time foreseen by the active timer.

IMPORTANT NOTE

The stove takes about 15 minutes to light.

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.

5.2.3. TIMER de-activation.

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

OFF.

ATTENTION!

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

If a timer programme has been activated, in the initial screen the stove operating status

(on/off/start-up….) alternates with the word “TIMER

P01 active” (example)

Chapter 5

page

36


5.3. SLEEP FUNCTION

PELLET STOVES


This function is only displayed with the stove lit and its purpose is to make selecting a programmed shutdown faster, without the need to programme the stove's internal TIMER.

To explain the SLEEP function in simple terms, basically it allows the stove to be turned off starting from a minimum of + 10 minutes respect the time read (example, if it is now 8:50, the first shutdown shall be 10 minutes later, that is at 9:00) and a maximum of 23.50 hours.

To set the function press Menu with the top right key then in the screen the word Date and Time appears, therefore scroll with the bottom right key until the word Sleep appears, confirm with Set. With the bottom right key set the shutdown time.

To confirm the choice press OK (top right) otherwise quit without saving any setting with ESC (top left)

If the SLEEP function is active with TIMER active, the former has priority, so that the stove shall not shutdown at the time foreseen by the timer but at the time established by the sleep function.

Once the sleep function is set, in the first screen the status of the stove (on/off) alternates with the sleep wording HH.MM. (HOURS-MINUTES).

When adjusting the sleep function, holding the right arrow key down when you reach 23.50 of the current day the panel prompts a stop: release it and press again to go on to the next day.

(default 10 minutes, changeable within the technical menu by an authorised MCZ technician). During this phase on the small panel display remains ON-ECO ACTIVE, but the flame drops automatically by one power per minute until it reaches P1 and stays there until the programmed "ECO shutdown T" lapses and if the room temperature is still achieved, it moves on to the shutdown phase.

ECO stop shutdown follows the normal shutdown procedure, whilst on the penal the wordings "SHUTDOWN" and "ECO ACTIVE" alternate.

The possibility of adjusting "ECO shutdown T" derives from the necessity of correct operation in the various environments in which a stove may be installed and avoiding continuous shutdowns and lightings in the case in which the room temperature is subject to constant changes (air currents, low room insulation etc.)

Once the stove shutdown conditions are reached, on the panel the words "OFF" and “ECO ACTIVE” alternate.

5.4.2.1. Mode AUTO-ECO

When ECO-STOP is activated and the chosen temperature selected, if the latter is lower than the current room temperature, the apparatus will immediately start counting the “ECO shutdown T”.

In the event of chosen temperature higher than room temperature the apparatus shall continue to work at full power until the requested temperature is reached.

5.4.3. Tones (Panel display: ON-OFF)

This setting deactivates sound when pressing the keys. It does not effect alarm signalling.

5.4.4. Pellet recipe - modifying the load

This function is for adapting the stove to the pellets in use. In fact, as they are several types of pellet on the market, stove operation is strongly variable according to higher or lower fuel quality. In the event that pellets tend to get blocked in the grate due to excessive load of fuel or in the case in which the flame is always high even at low powers and vice versa if the flame is low, it is possible to decrease/increase the pellet feed rate into the grate:

5.4.6.2. Operating mode with external thermostat and Eco-Stop

When the external thermostat and Eco Stop are active the stove actuates the operating conditions described in para. 5.4.6.1, replacing the command coming from the thermostat at the temperature read by the probe, so that:

- When the temperature is achieved (thermostat contact open) the decrease in ECO shutdown T" starts (default 10 minutes, changeable (*) from inside the TECHNICAL MENU). During this phase on the small panel display remains ON-ECO ACTIVE, but the flame drops automatically be one power per minute until it reaches P1 and stays there until the programmed "ECO shutdown T" lapses and if the thermostat is still open, it moves on to the shutdown phase.

Once the stove shutdown conditions are reached, on the panel the words "OFF" and “ECO ACTIVE” alternate In this state if the room temperature drops below that set (thermostat contract closed) the stove relights without any delay.

5.4.7.1. General characteristics of the LCD remote control

The KAIKA and FACE stoves are mainly controlled by the control panel that is found above the stove. As an accessory, it is in any case possible to purchase the remote control that manages the main functions: on/off, power adjustment, hot air fan speed adjustment, automatic function.

The remote control is activated on the stove control panel on settings - remote control – ON-OFF.

The remote control is the infrared type so the signal cannot pass beyond walls or other solid obstacles, it can however exploit the reflection of the waves on the walls of the room.

Keep the remote control away from direct heat and water.

It is advisable to keep it out of the reach of children.

5.4.7.2. Type of batteries and replacement

To substitute the battery, it is necessary to extract the battery-holder

(as shown on the figure on the back of the remote control), and remove or insert the batteries following the symbols printed on the remote control and the battery itself.

Operation requires 1 CR 2025 Lithium battery.

Used batteries contain metals which are harmful for the environment; they must therefore be disposed of separately in the special containers.

If the remote control is off due to the absence of batteries, it is possible to control the stove from the control panel, located in the upper part of the stove.

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.

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

5.4.8. Hopper load (ON-OFF - only displayed with stove off)

This parameter, only displayed when the stove is off, allows the pellet to be loaded in the loading system (hopper) and can be used every time it is emptied when the pellets in the tank run out (see alarm A02).

It is useful for preventing the stove from not lighting (alarm A01) because the tank has been emptied.

When the pellet starts its descent into the grate press the Esc key and proceed with lighting the stove

6. SAFETY DEVICES

The stove is fitted with the following safety devices:



SMOKE TEMPERATURE SENSOR.

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



PELLET HOPPER TEMPERATURE SENSOR.

If the temperature surpassed the set safety value, it immediately halts the stove's operation and to restart it is necessary to wait until the stove has cooled down



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 rapidly shuts off the supply of pellets and an alarm is displayed.



BREAKDOWN OF THE REDUCTION MOTOR

If the gear motor stops, the stove shuts down and the relative alarm is signalled



TEMPORARY POWER CUT

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



FAILURE TO LIGHT

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

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

6.1. ALARM SIGNALLING

Should an operating condition other than that foreseen for normal stove operation take place an alarm condition is triggered. The control panel shows the reason for the alarm in progress and by pressing the info key summarised instructions are given on how to proceed to restore the stove. The alarm sound signalling is not foreseen for A01 and A02 so that the user is not disturbed if pellets run out during the night.

Check the level of pellets in the hopper.

Check that the grate is properly inserted in its housing and does not have any obvious unburnt incrustations;

Wait for the end of the cooling phase, cancel the alarm and relight the stove placing the fuel load to minimum

(SETTINGS MENU - Pellet recipe) and increasing the room fan speed. (V1-V5).

If the alarm persists, contact technical support.

Check that the grate does not have visible unburnt incrustations. If the alarm persists, contact technical support.

A09

Smoke temperature too high or smoke probe faulty

Wait for the end of the cooling phase, cancel the alarm and relight the stove placing the fuel load to minimum

(section 5.4.4.) and increasing the room fan speed (section

5.4.5). If the alarm persists, contact technical support.

6.2. Exiting alarm condition

To reset the alarm hold the On/Off key down for a few moments: the stove runs a check to assess whether the cause of the alarm persists or not. In the first case the alarm will be displayed once again, in the second case it will go to Off.

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

6.3. Normal shutdown (panel display: shutdown)

If the shutdown key is pressed or there is an alarm signal, the stove enters the thermal shutdown phase foreseeing automatic execution of the following phases:

 Pellet loading stops

 The room fan maintains set speed until smoke T reaches

100°C, then it automatically sets to minimum speed until shutdown temperature is reached

 The smoke fan sets on maximum and stays there for a fixed time of 10 minutes, at the end of which if smoke T has dropped below 45°C (parameters can be displayed in the INFO menu) it shuts down definitively, otherwise it sets to minimum speed until such threshold is reached and then shuts down.

6.4. BLACKOUT WITH STOVE LIT (panel display:

RELIGHTING AFTER BLACKOUT for 10’, then

LIGHTING)

In the case of no mains supply (BLACKOUT) the stove performs as follows:

 Blackout less than 10”: it restores operation in progress;

 If there is no power supply for more than 10" when the stove is lit or in the lighting phase, when the stove is powered again it returns to the previous operating condition following the procedure below:

1. It cools down by activating the smoke extractor at the minimum for 10’ and proceeds to the next point;

2. It restores the stove to the operating condition before the blackout.

During phase 1 the panel displays RELIGHTING AFTER BLACKOUT.

During phase 2 the panel displays Lighting.

If during phases 1-2 the stove receives commands from the panel (or from the remote control) and therefore manually performed by the user, the stove stops running blackout recovery and proceeds with lighting or shutdown as the command requests.

If the power supply cut is LONGER THAN 10” with the stove in shutdown phase, when the stove is powered again it restarts in shutdown mode even if the smoke temperature has dropped below

45°C in the mean time. This last phase can be skipped by pressing key

0/1 (passes on to lighting) and by pressing it again (it recognises that the stove is off).

Clean the grate “F” from ash and any incrustations which could obstruct the air passage holes.

7. 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.

7.1. DAILY AND WEEKLY CLEANING BY THE USER

Chapter 7

page

Example of clean grate

7.1.1. Before each lighting

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

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

REMEMBER THAT ONLY A CORRECTLY POSITIONED

AND CLEAN GRATE CAN GUARANTEE THE OPTIMAL

LIGHTING AND OPERATION OF YOUR PELLET STOVE.

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.

Example of dirty grate

7.1.2. Check every 2/3 days

Clean and empty the ash drawer, watching out for hot ash.

Only if the ash is completely cold, it is possible to use a vacuum cleaner to remove it. Use a drum-type vacuum cleaner that is suitable for picking up particles of a certain size.

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

It is however advisable not to let it exceed 2 or 3 days.

Once the operation is finished, reinsert the ash drawer below the grate making sure it is well inserted

PELLET STOVES


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.

7.2.2. 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)

7.2.3. 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:
