INSTALLATION AND USE MANUAL

2. INSTALLATION IN ACCORDANCE WITH UNI 10683

2.1. OPERATING AREA

For good operations and good heat distribution, the fireplace stove should be positioned in a place where the air required for combustion can flow (at least 60 m standards and current regulations in the country of installation.

The room volume must not be less than 60 m

Air must enter through permanent apertures on the walls (near the fireplace stove) that open outdoors with a minimum section of 360 cm

These apertures (air vents) must be made so as not to be obstructed in any way.

Air can also be taken from adjacent rooms as long as these are equipped with outdoor air vents and not bedrooms or bathrooms or rooms where fire hazards do not exist such as garages, wood sheds, flammable material warehouses, strictly observing the provisions of current regulations.

• Fireplace stoves may not be installed in

bedrooms, bathrooms and where another heating device is installed without autonomous air flow (fireplace, stove, etc.).

• Placing the fireplace stove in explosive

environments is prohibited.

• The floor of the room where the fireplace stove

is to be installed must be strong enough to support its weight.

• In the event of wood floors, install a protective

covering in accordance with current regulations in the country of installation.

• If walls are not flammable, install the fireplace

stove at least 5 cm from the walls.

/h must be available) according to installation

Chapter 2

page

2.2. PRECAUTIONS

The fireplace stove must be installed in a suitable surface that permits routine opening and maintenance operations.

The room must be:

• suitable for room operating conditions

• equipped with power supply 230V 50 Hz (EN73-23)

• equipped with an adequate smoke exhaust system

• equipped with outdoor ventilation

• provided with an earth connection complying with CEI 64-8

IMPORTANT!

• The fireplace stove must be installed and

assembled by qualified personnel.

• The fireplace stove must be connected to a flue

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

• The fireplace stove must be connected to a flue

pipe or an internal or external vertical duct conforming to current standards UNI 7129 7131 9615.

• Smoke is generated from burning wood and,

therefore, may dirty adjacent or nearby walls.

• Before positioning the fireplace stove, you must

make a hole for the intake of external air.

2.3. EXTERNAL AIR OUTLET

INSTALLATION AND USE MANUAL

Chapter 2

page

The room where the stove is installed must have at least as much air as requested by normal combustion of the equipment and by room ventilation. This may take place through permanent apertures in the room walls that lead directly outdoors or ventilated rooms according to UNI 10683 REV.

For this purpose, drill a hole with minimum 360 cm² free section near the fireplace stove (22 cm diameter or a 20x18cm rectangle), protected by an indoor and outdoor grille.

The air intake must also:

• directly communicate with the installation room

• be protected by a grill, made of metallic anti-insect mesh or a

suitable protection as long as it does not reduce the minimum section.

• be installed so as to avoid obstruction

• for ducts, up to 3.5 linear metres, increase the section by about

5% while increased by 15% for larger measurements.

Remember that the ventilation grills always have a cm

useful section on one side. When selecting the grill and hole dimension, make sure the useful grill section is greater than or equal to the section required by MCZ for product operations.

Connecting the air outlet directly to the fireplace stove is not mandatory but the above mentioned section must guarantee about 50 m³/h of air. See standard UNI 10683 REV.

IMPORTANT! Air flow may also be obtained from a room adjacent

to the installation room as long as this flow is free through permanent apertures that directly communicate with the outdoors; avoid air outlets connecting with heating units, garages, kitchens or bathrooms.

INSTALLATION AND USE MANUAL

2.4. CONNECTION TO THE FLUE PIPE

Chapter 2

page

The connection to the flue pipe is a very important element. The connection must be made with a great deal of care; in the event of erroneous or anomalous construction, it is extremely difficult to remedy without damaging the hood liner. In addition, the connection is made in a part of the stove where temperatures are very high, and for this reason it is important to use materials that are capable of resisting heat and also the acidity of the fumes produced by combustion.

Before beginning work, please note the following:

• The connecting pipe must have a maximum slope of 45

degrees. This is to avoid excessive deposit of condensation produced in the initial phases of lighting the fireplace stove, and/or the excessive accumulation of creosote. It also keeps the release of smoke from being slowed down.

• The connections must be made of stainless steel 316

with a minimum thickness of 10/10, or in aluminised steel, minimum thickness 20/10. It is prohibited to use stainless steel or aluminium hoses as they compromise the safety of the connection and are subject to tears and gaps, causing leakage of smoke.

• The components making up the connecting pipe must be

perfectly sealed.

• The joint to the flue pipe must not be too long (to avoid

obstructions), nor too short (to avoid smoke leakage).

If metal connecting pipes are used, they must be insulated with suitable material such as ceramic fibre matting, to avoid deterioration of the masonry and of the decorative hood liner.

IMPORTANT! Any increase in the section of the connecting pipe

must start immediately above the hood of the fireplace and not along the flue pipe section.

2.5. FLUE PIPE

The flue pipe is a fundamental element in discharging smoke and

therefore must have the following requisites:

• It must be waterproof and thermally insulated.

• It must be made with heat resistant materials, resistant to

combustion products and any condensation.

• It must have a vertical slope with axis deviations not over 45°

and without narrowing.

• It must meet the requisites indicated in the technical table for

the internal chimney section and height.

• It must preferably have a circular interior section.

• If pre-existing and previously used, it must be cleaned.

The flue pipe is of primary importance for the correct functioning and safety of your fireplace stove.

INSTALLATION AND USE MANUAL

2.5.1. Examples of flue pipes

AISI 304 stainless steel flue pipe with dual chamber insulated with ceramic wool or equivalent resistant to 400°C.

EXCELLENT

Flue pipe in refractory brick with insulated double wall and external coat of cement mix lightened with honeycomb material such as clay.

GOOD

Square or rectangular section flue pipes must have rounded internal corners with radius not less than 20mm. For the rectangular section, the ratio between internal dimensions must be ≤1.5.

The recommended section for a flue pipe according to its length is listed in the table below:

Height (m) Section (cm²)

Traditional square section clay flue pipe with insulating hollow inserts.

GOOD

Chapter 2

page

Avoid flue pipes with internal rectangular sections whose larger side is double the smaller such as 20x40 or 15x30.

AVERAGE

From 3.5 to 5 m

From 5 to 7 m

Over 7 m

900 (30x30 cm or ∅ 30 cm)

625 (25x25 cm or ∅ 25 cm)

400 (20x20 cm or ∅ 20 cm)

N.B. Too small or too large a section reduces draught and insulation.

For special sections, or section or path variations, functional smoke exhaust inspections must be conducted as per UNI 9615.

The smoke duct should be equipped with a solid material collection chamber at the mouth of the smoke duct to be easily opened with an airtight door.

IMPORTANT !

If in doubt about your flue pipe operations or if its dimensions are different from those recommended, we highly suggest an authorised MCZ technician inspect and measure flue pipe performance (via micro-gauge measurements)

MCZ s.p.a. shall not be held liable for poor operation of the fireplace stove that is due to a flue pipe of improper size or installation that does not comply with provided requirements.

INSTALLATION AND USE MANUAL

2.6. COWL

If underestimated, it is a severe impediment to correct "chimney system" operations.

Flue pipe draught also depends on its cowl.

Therefore, if hand made, its four exhaust sections must correspond to

more than twice the internal section of the flue pipe. Having to exceed the peak of the roof, the cowl will be

exposed to wind, therefore an industrial type is recommended.

An industrial cowl, with prefabricated sections fitting together, allows optimal disposal of the flue gases.

The cowl must meet the following requisites:

• It must have an internal section equal to that of the chimney.

• It must have a useful output section not less that double that

of the internal section of the flue pipe.

• It must be built to prevent rain, snow and any foreign objects

from getting into the flue pipe.

• They must be installed to guarantee adequate smoke

dispersion and out of the reflux area where negative pressure forms.

For paired flue pipes, the cowl for solid combustion and the one for the upper floor must be at least 50cm higher than the other to avoid pressure transfers between paired flues.

The cowl must not have obstacles within 10 m such as walls, roof slopes and trees. Otherwise, raise it at least 1 m over the obstacle and, in the event of other nearby cowls, keep them at least 2 m away. In any case, the cowl must exceed the peak of the roof by at least 1m.

A traditional handmade cowl. The right exhaust section must be at least twice the internal section of the flue pipe, 2.5 times is ideal.

INSTALLATION AND USE MANUAL

4. INSTALLATION AND ASSEMBLY

IMPORTANT! The fireplace stove must be installed and connected

to the smoke duct only by a specialized technician, so that all local and national regulations are complied with.

Installation must in any case by carried out in compliance with UNI 10683.

When the fireplace is unpacked, check for perfect operation of all its parts or any damage which may have occurred during shipping. The retailer or the carrier must be immediately informed of any damage.

If the fireplace stove is installed in a place that is difficult to reach, its weight can be reduced by removing the internal parts that make up the

fire box. However, be sure to put all of the parts back in place.

This operation is to be carried out only by specialized personnel.

MCZ shall not be held liable if the preceding warning is not complied with.

Chapter 4

page

4.1. PREPARATION AND UNPACKING

Open the packaging, take off the straps, remove the fireplace stove from the pallet and position it in the chosen location, taking care that its position complies with the above instructions.

The fireplace stove must always be kept VERTICAL while moving and only using hand trucks. Do not drag the unit as this may damage the support feet.

Be especially careful that the door and its glass are protected from mechanical collisions that could jeopardise their integrity.

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

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

The final user must store, dispose or recycle packaging material in accordance with local regulations.

4.2. SELECTION OF OPERATING MODE

IMPORTANT! Before installation you will need to decide which

system to adopt.

The Airsystem can distribute hot air either by NATURAL CONVECTION (VN) or by FORCED CONVECTION (VF) through the

use a forced ventilation kit composed of a fan, control unit and radio remote control.

Example of fireplace stove packing

INSTALLATION AND USE MANUAL

4.2.1. Natural convection (VN)

If you adopt this system, the knockout panels in the lower part of the stove body must be removed in order to facilitate heat exchange

and air circulation.

Airsystem line with the exception of Airsystem B70

In all models of the Airsystem line, except for model B70, the knockout panels are located under the bottom of the unit as shown in

figure 1

The sum of the sections of the knockout panels is equal to the section of the two upper cut-outs for the ducting of hot air. Therefore, by opening all the knockout panels, it is possible to duct two upper outlets. If you decide to use this method of ventilation, it is not advisable to duct more than two nozzles to prevent air dispersion in the tubes.

Airsystem B70

Differently from all the other models, the Airsystem B70, for reasons of construction, does not have knockout panels on the bottom; instead, they are located on the steel sides. The cut-outs are circular in shape, Ø 150 mm. They should both be opened if you want to duct the two nozzles for the distribution of hot convection air

(figure 2).

To open the knockouts, whether they are on the sides or under the unit, hit them with a rubber mallet and remove the profile that detaches from the unit.

ATTENTION! With the fireplace stove thus prepared (knockout

panels removed), it is NOT ADVISABLE to install the forced ventilation kit afterwards.

Chapter 4

page

Figure 1 – Airsystem line knockout panels

4.2.2. Forced convection (VF)

If you implement this system, you must not remove the knockout panels located on the bottom or side of the unit and purchase the

FORCED VENTILATION KIT 180-480-620 m Then proceed accordingly when specified in

/h optional.

paragraph 4.8 “Installation

of forced ventilation kit".

4.3. RELEASE OF COUNTERWEIGHTS

The fireplace stove is delivered with the sliding counterweights locked in place. In this way, during shipping and handling, they will not strike and damage the sliding parts, the door and the ceramic glass.

To release the counterweights and therefore also the door, remove the screws as shown in

Remove the screws that hold the counterweights only after you have positioned the fireplace stove and to ensure that the glass is in good condition.

DO NOT MOVE THE FIREPLACE STOVE WITHOUT THE SCREWS THAT HOLD THE COUNTERWEIGHTS.

Damage caused by failure to observe this rule is the responsibility of the client or his representative.

INSTALLATION AND USE MANUAL

4.4. INSULATION OF FIREPLACE STOVE

The fireplace stove must also always be separated from nearby walls and ceilings.

If necessary, use insulating materials to insulate the walls that are in

contact with the unit if they may be damaged or catch fire (walls made of wood, plasterboard, etc.).

(figure 4)

4.5. POSITIONING

Co ibenta z ione

Chapter 4

page

The AIRSYSTEM fireplace stove can be placed in a corner or along a wall. You can customize with MCZ claddings or install them during construction with materials that are resistant to high temperatures.

The fireplace stoves are self-supporting single-piece units that simplify installation and do not require any additional support.

Always evaluate the structural condition of the surface which will take the weight, and always leave a minimum 5 cm airspace between the stove and any walls.

Install dry the fire bed of the cladding leaving an opening of 1 cm

for the insulation.

(Figure 5)

If the stove is positioned over a floor or close to walls made of flammable materials, it is advisable to use sufficient insulation.

4.6. ADJUSTMENT OF HEIGHT AND BALANCING

The Airsystem is equipped with adjustment feet that are to be screwed

into the unit only after its exact position has been determined.

Their purpose is to allow easy levelling of the fire bed. The feet allow adjustment from a minimum of 2 cm for some models, up to a maximum of 4 cm for others.

Figure 6

possible according to the various models. If you want to raise the fireplace stove more than 2 cm, you need to

create a masonry pedestal to set the product on. Do not eliminate

the feet. They are indispensable for levelling. Removing the feet is considered a structural modification of the product and therefore voids the guarantee.

The levelling of the fireplace stove is essential so that the fire door slides correctly.

If the fireplace stove is not placed level, there is the risk that door will not close perfectly, and that the internal counterweights strike the structure, causing noise each time the door is raised or lowered.

It is possible to adjust the levelling of the fireplace stove by checking the sliding of the door until the counterweights no longer make any noise.

INSTALLATION AND USE MANUAL

4.7. EXTERNAL AND INTERNAL AIR INTAKE

4.7.1. Fireplace stove with natural ventilation

If the fireplace stove is installed with natural ventilation, i.e. with no

electric fan, make an external combustion air intake of 300 cm²

net behind the unit so that fresh air always flows beneath the fireplace stove.

(figure 7)

You must comply with this instruction fully, because otherwise a lack of oxygen may compromise combustion and calorific energy of the product.

4.7.2. Fireplace stove with forced ventilation

4.7.2.1.

Ducts for kit VF 480-620 m3/h

Chapter 4

page

Air intake of 300 cm2for combustion air and natural convection

If the fireplace stove is installed with forced ventilation, i.e. using a fan of 480 or 620 m

/h, place air intakes and ducts as follows:

for proper air circulation in the room, it is advisable to connect one of the two ducts to the exterior of the home, creating an air intake

of 150 cm² the room where the fireplace stove is installed (also of 150 cm²

, in order to draw in clean, fresh air; place the other in

This mode allows a proper mix of the air in the room of installation and better cooling of the structure of the fireplace stove.

(Figure 8)

If you cannot make this kind of connection, you will still need to connect both ducts, whether they are both directed to the exterior or the interior. Depending on the selection, you will have operating temperatures that are slightly above or below average but which do not compromise proper operation of the product.

ALWAYS

CONNECT THE TWO DUCTS AND RUN THEM

OUTSIDE THE CLADDING OF THE FIREPLACE STOVE. IF THIS DIRECTIVE IS NOT OBSERVED, THE FAN,

HAVING GREATER STATIC PRESSURE, MAY ALSO INTAKE AIR INTENDED FOR THE FRONT GRILLE OF THE FIREPLACE STOVE AND REQUIRED FOR COMBUSTION

require ducts, since the lower power of the fans and their position

with respect to the fireplace stove allow proper operation of the system provided a considerable quantity of air is provided under the unit.

Considering that this type of fireplace is normally set in an internal wall of the home and it is almost never possible to provide ducts to the outside of the home as with the previously described model, the ventilation air must all be drawn from the room of installation, using the air intakes on each side of the cladding

It is necessary to provide two air intakes with a net minimum section

of 150 cm

• Change operating mode from manual to automatic and vice

versa (red key)

• Variation of the 4 speeds of the fan (yellow keys)

4.10.2. Turning on and off

TURNING ON: Press and hold the blue ON/OFF button of the radio

remote control to turn the fan on at the first speed

in MANUAL mode. The control unit emits a short beep that identifies 1

speed in manual mode.

TURNING OFF: Press and hold the blue ON/OFF button of the radio

remote control to place the device in STAND-BY

mode, which is signalled by a very long beep, and

shut down the fan.

4.10.3. Manual mode

By default, when turned on using the ON/OFF button, or simply by clicking the red MAN/AUT button, the system goes into MANUAL mode.

This mode can be recognized by the fact that all of the sound

signals emitted by the control unit in this status are short beeps and the fan is always on regardless of the temperature.

The yellow + and - buttons are used to increase/decrease the speed of

the fan from 1 number of short beeps that corresponds to the selected speed:

4.10.4. Automatic mode

Once ventilation is turned on in manual mode, by pressing the red MAN/AUT of the radio remote control, the device goes to AUTOMATIC

mode. The mode can be recognized by the fact that all the sound

signals emitted by the control unit in this status are long beeps.

The yellow + and - buttons are used to increase/decrease the speed of

the fan from 1 number of short beeps that corresponds to the selected speed:

Ventilation is turned on and off exclusively by the temperature of the thermostatic probe.

AUTOMATIC START BY MEANS OF THE PROBE:

If the temperature detected by the probe is greater than 45°C, the fan comes on at the set speed (1

to 4th and vice versa. The control unit responds with a

1st speed= 1 long BEEP

speed= 2 long BEEPS

speed= 3 long BEEPS

speed= 4 long BEEPS

speed) and an internal timer is activated

INSTALLATION AND USE MANUAL

that performs a countdown starting from 40 minutes. This period of 40 minutes is called the “

warm-up phase"

After 40 minutes, if the temperature of the probe exceeds 65°C, it means that the internal temperature is rising because the fireplace stove is coming up to operating power, and therefore the fan must stay on. After 40 minutes, if the probe does not reach 65°C, it means that the power of the fire is low and the ventilation must be shut off.

If the user changes the speed while the system is between 45°C and 65°C, this is interpreted as a request for ventilation. The system goes back to the

warm-up phase;

the timer is reset to 40 minutes and the

countdown begins.

AUTOMATIC SHUTDOWN BY MEANS OF PROBE:

If the temperature probe drops below 65°C, ventilation is shut off.

Chapter 4

page

4.10.5. Other functions of the control unit FC 715

STAND-BY: The fan is off because the blue ON/OFF button of the

radio remote control has been pressed. Shutdown is signalled by a long beep.

SAFETY: In STAND-BY status, if the temperature exceeds 150°C, the

fan comes on at speed 1 and the system goes into AUTOMATIC mode. Ventilation continues until the temperature drops below 65°C.

STATUS RECOVERY: the system automatically saves, in non-volatile

memory, the last power setting made by the user, allowing continuation at the speed after a power outage.

4.10.6. Setting transmission code of the radio remote control

The radio remote control and the control unit are set with a neutral code that makes it possible to check operation of the ventilation kit immediately, before the cladding is completely installed.

It may however be necessary to change this code, and as a result the transmission frequency, if another fireplace stove is located nearby (e.g. if your neighbour has one) or if other signals interfere with transmission.

The code can be personalized as follows:

• Unplug the control unit

• Open the battery compartment of the radio remote control by

moving the cover in the direction of the arrow

(Figure 20)

• Raise any one, or more than one, of the 10 white keys as

shown in the example in

figure 21.

• Close the radio remote control

• Press and hold the red key of the radio remote control, and at

the same time plug it back in.

• After a maximum of 15 seconds, a prolonged beep or a series

of beeps in sequence confirm that the radio remote control has been connected to the control unit with the new code.

4.11. CONNECTION TO THE FLUE PIPE

We recommend connecting the stove to the flue pipe by means of pipes and bends in aluminised steel, capable of withstanding the high temperatures which are reached in that section of pipe, and of resisting corrosion from the fumes. These connecting pipes are available on request in various sizes (see our price list), and they simplify installation, as they are assembled by fitting one into another.

Any increase in the section of the connecting pipe must start immediately above the hood of the fireplace and not along the flue pipe section

When installation is complete, the smoke connection must be insulated with ceramic fibre matting or material that is resistant up to at least 600°C.

page

For the ducting of hot air, it is necessary the install the hoses Ø 150

mm C (optional) on the flanges located on the upper part of the fireplace stove B. First of all, remove the knockout panels A located at

the top, using a rubber mallet or a similar tool. After breaking out the

knockout panel, remove it so as to fasten the flanges B. Fasten the flanges with the screws provided. Connect the hoses C using the hose clamps D. In the part opposite the hose, apply the adjustable nozzles E

which will subsequently be anchored to the decorative hood lining.

figure 22)

(see

It is advisable to:

• Insulate the ducting tubes, for example with ceramic fibre, to

isolate them from the decorative hood liner and avoid the transmission of vibrations from the forced air fan.

• Limit the ducting to 2 linear metres for natural

ventilation, and 4 linear metres for forced ventilation.

• Insert the hot air outlet nozzles at least 2 m above the floor.

• If possible, provide ducts of the same distance to prevent

different quantities of air at different outlets.

ATTENTION! Make sure that when the stove is lit, the shutters on the nozzles are completely open, to avoid dangerous overheating.

and/or stone, and to allow normal thermal dilation. Use care with wood finsihes such as crossbeams or shelves.

We recommend making the hood liner in fire-resistant plasterboard of 15/20 mm. thickness, with a self-supporting frame in

galvanised profile, so as not put weight on components of the cladding (such as wooden beams and marble architraves) which do not have a

load-bearing structure and to make it easy to work in the event of

future anomalies and/or maintenance.

Dry install the fire bed of the cladding, leaving an aperture of 1 cm

between the fireplace stove and the fire bed to provide insulation.

It is advisable to place the nozzles at a height of not less than 2 m from the floor in order to keep hot air from flowing directly onto individuals.

As an alternative, it is possible to install a single nozzle (see our price list) which is to be placed by making a rectangular hole of 16x48 on the front or side where the hoses Ø 150 mm for hot air outlet are to be connected

(Figure 24).

5. OPERATION

5.1. PRE-LIGHTING WARNINGS

Do not touch the fireplace stove when it is lit for the first time. During this phase, the paint finishes drying and hardens. 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.

If necessary, touch up the paint with the aerosol spray in the original colour (see “Fireplace stove accessories and

inserts")

Do not stay near the fireplace 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 fireplace 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 very important not to bring the stove up to full heat immediately. Bring it up to temperature gradually.

This avoids damages to welds and the steel structure.

Do not demand full heating performance straight away!

5.2. OPERATING TEST

ATTENTION!!

BEFORE PROCEEDING IN ANY WAY WITH THE INSTALLATION OF THE CLADDING, CARRY OUT A GENERAL TEST OF THE FIREPLACE STOVE AS FOLLOWS:

• Raise and lower the fire door 7-8 times to ensure

fluid sliding and that the counterweights do not produce noise when they come into contact with the structure (if this anomaly occurs, review chapter

4.6)

• Check that all of the wiring and the control unit

(if the kit VF is installed) are always placed at a distance from the hot body of the fireplace stove.

• Test the ventilation kit at all speeds and in all

modes (if kit VF is installed)

• Light the fire at low power to ensure the smoke

connections do not leak smoke or soot. Before lighting, however, read Chapter 5.

INSTALLATION AND USE MANUAL

MCZ SHALL NOT BE HELD LIABLE FOR ANY DAMAGE WHICH THE CLADDING MAY SUFFER IF THE AFOREMENTIONED CONTROLS ARE NOT PERFORMED AND IT BECOMES NECESSARY TO DEMOLISH THE CLADDING TO PERFORM REPAIRS OR ADJUSTMENTS.

5.2.1. Phases for first test lighting

• Make sure you have read and completely understood the

contents of this instruction booklet.

• Remove any components which might burn from the fireplace

stove and door (various instructions and adhesive labels).

• Remove the stickers from the ceramic glass or the high

temperature could melt them and irreparably damage the glass. In this case, the MCZ warranty does not cover the glass.

• Open the front register of the combustion air all the way.

• Place wood in small pieces that is well dried (humidity 15/20%).

Light the fire at low power without excessively heating the structure. Any odours from manufacturing residue and/or evaporation will form the first time lighting occurs, and will disappear after a lighting at full power has occurred a few times.

Chapter 5

page

Figure 25 – Maximum adjustment of combustion air opening

5.3. CHOICE OF FUEL

To obtain the maximum performance from your AIRSYSTEM fireplace

stove, it is of primary importance to use wood with suitable

characteristics. It is advisable to use wood for heating such as oak, beech, locust

tree, or oak with good calorific energy, or logs of pressed wood that do not have resin. These have a high calorific power and must be used with caution to avoid overheating which could damage the stove.

It is advisable to use fuels such as poplar, pine, lime tree, or chestnut which have low calorific power, since they are soft wood and

also they do not burn for a long time.

Avoid using fuels such as pine, fir, and olive as they contain a high

degree of resin and their combustion may substantially soil the fire mouth and the ceramic glass; also, they do not have an exceptional yield.

For all types of wood listed, the humidity they contain is essential because it determines the calorific energy.

Do not use treated fuels (such as painted or varnished wood, or particle board) or unsuitable materials (such as plastics and derivatives), which could release toxic or polluting substances. Do not burn rubbish.

The gases produced by combustion due the use of unsuitable fuels cause damage to the fireplace stove and the chimney, they cause pollution and can compromise your health.

INSTALLATION AND USE MANUAL

A high percentage of humidity produces condensation in the smoke duct causing an alteration in the draught and generating smoke and a significant deposit of soot on the glass of the door and in the flue pipe with a possible risk of

a chimney fire later on.

5.4. FIRST LIGHTING

It is advisable to approach the first lighting with caution, using good-quality, well-seasoned wood.

The primary air inlet must be fully open. Do not use alcohol, petrol, or other volatile flammable substances. On first lighting,

fumes and unpleasant smells may be given off, caused by the drying of the product; this is not hazardous, and it is sufficient to ventilate the room. Once combustion has started, pieces of wood of normal size may be added.

The flame must have as far as possible a smooth and laminar flow. On

the various occasions when the stove needs reloading, the door should be opened slowly, to avoid blowbacks of smoke into the room.

Proceed as follows:

• Place a small amount of balled paper in the stove.

• Cover the paper with a small quantity of twigs and a few pieces of

wood.

• Open the primary air register completely (lever all the way to the

right).

• Light the paper, and if necessary leave the door up.

• When the twigs are burning, the door can be closed.

As the fire burns, add wood. Never overload the fireplace stove with wood (see technical specifications in the table).

As soon as the flames have died down and a bed of embers has formed, load the stove normally. Small loads of wood are preferable to large ones for combustion.

Chapter 5

page

Attention

• Do not use volatile, flammable substances

(petrol, alcohol etc.) for lighting the fire.

• Do not use fuels which could release toxic

substances or pollutants.

• Do not put the fire out by throwing water on it.

• Check the external and internal air intakes, and

the flue pipe, at least once a year, arranging for them to be cleaned.

• During use, the metal parts and the glass reach

high temperatures. For all jobs of loading the stove, adjustment or cleaning the ash drawer, use the insulating glove provided.

• Never leave children unattended near the

fireplace stove when it is in use.

• The risk of burns from contact with hot surfaces

is very high.

INSTALLATION AND USE MANUAL

5.5. LOADING THE FUEL

For normal fuel loading, lift the handle as shown in

figure 27

. To close the door, do the opposite.

During use, the metallic structure, the handle and the glass become very hot. Use the thermal glove provided when handling these parts.

During normal use, always keep the fire door completely down and closed. Intermediate positions cause abnormal combustion (forge

effect), rapid wood consumption, and may cause smoke to leak out due to the high temperature of the fire box.

Open the door only to add fuel, and only for brief periods of time.

The fireplace stove works best and provides the greatest yield when the door is closed, because the hermetic combustion chamber and the calibrated inlet of oxygen allow increased performance.

Figure 27 – Opening/closing the fire door

5.6. CONTROL OF COMBUSTION

Chapter 5

page

PRIMARY AIR

The fireplace stove is equipped with primary air emission from the front part which ensures combustion and helps keep the glass clean. Moving the lever to the right provides the full aperture, and more rapid combustion, while moving it to the left closes the opening, with slower burning.

SECONDARY AIR

Adjustment is performed using the same lever as for the primary air. Secondary air comes out in proportion to the primary air. This balance is pre-calculated; the user cannot change it, as this may cause incorrect adjustment. This will prevent excessive combustion.

The use of damp or treated wood emits a higher quantity of smoke than normal that can dirty glass faster. Also the low performance of the flue pipe can jeopardise glass cleanliness since smoke remains in the combustion chamber longer than

normal.

5.6.1. Removal of upper deflectors to improve release of smoke

If your flue pipe is not in the best condition and when you check combustion you notice that:

• The smoke remains in the smoke mouth for too long

• The flame is very red and feeble

• The glass gets dirty very quickly

• The internal refractory material in Alutec® is very dirty

it probably indicates poor performance of the flue pipe. Therefore it is necessary to facilitate evacuation of smoke.

To resolve this issue, the MCZ Airsystem line lets you easily modify the upper deflector assembly, which normally deals with carrying the smoke into the flue pipe.

Figure 28 – Adjustment of primary/secondary air.

INSTALLATION AND USE MANUAL

If you remove one or both of the upper deflectors, located in the steel hood above the fire mouth, it lets the smoke rise vertically without obstructions towards the flue pipe.

Always remove the higher deflector first (the smaller one). Only

after re-lighting the fire and checking operation, remove the second lower deflector (the larger one).

The deflectors are simply set on internal brackets. Therefore, to remove them, just move them in the direction of the arrow as shown in

figure

29.

Removal of the deflectors should not become a matter of routine. You should only do it when there is no other

way or improving an old or small flue pipe short of rebuilding it.

Removing the deflectors without due reason causes smoke to exit more rapidly and decreases thermal exchange, with lowers the performance of the fireplace stove. This does not happed if draught is insufficient because the smoke already spends too much time in the combustion chamber and has

time to make the proper exchange.

This should be carried out by the installer at the moment of test lighting. Never operate the fireplace stove with only the upper deflector (i.e. the smaller one) as this may force smoke towards the fire door and allow smoke to get into the room.

The steel deflectors get very hot. Therefore, before removing them, make sure the fireplace stove has been shut down and has cooled for some time.

5.7. COOKING FOODS

Only certain models of the Airsystem line are suited for cooking foods on the grille with the fire door open

(Airsystem F80).

Therefore, if you want to cook on a model that is not set up for it, it is advisable first to form a bed of coals with no flames. Then open the door only to turn the food over on the grill, which must fit in the fire bed.

5.8. EMERGENCY SITUATIONS

If for any reason the stove fire needs to be suddenly and quickly put out or a fire in the flue pipe needs to be put out, proceed as follows:

• If time allows, remove the grate and ashes, using a metal

container.

• Put the fire out rapidly by means of a dry carbon dioxide (CO

extinguisher.

INSTALLATION AND USE MANUAL

6. MAINTENANCE AND CLEANING

ATTENTION! All cleaning operations of all parts should be

conducted with the fireplace stove cold.

6.1. CLEANING TO BE PERFORMED BY THE USER

6.1.1. Cleaning the glass

Specific products can be used to clean the glass (see our price list), a cloth dampened with water and ammonia or a bit of white ash and a

newspaper.

To open the flap door in order to clean the inside of the glass,

completely lower the fire door A and block the left-hand sliding guide by pulling on lever B. Insert the provided key C in the lock located in

the middle of the left hand side of the structure of the fire door and turn the key clockwise to unlock. Open the door as shown in

To close, perform the steps listed above in reverse order.

ATTENTION! Do not spray the product on the painted parts or on

the gaskets of the door (ceramic fibre cord)

6.1.2. Cleaning out the ashes

This must be done when the fireplace stove is off and cold. It is advisable to adequately clean the ash drawer for proper

combustion.

Ashes which are still hot must neither be dumped outside in an uncontrolled manner nor put in the dustbin. Leave them to cool down in the open air in a metal container.

Using the hook provided, rotate the grille in its housing and lean it against the back of the stove. Raise and extract the ash drawer and empty it in a fireproof container (metal bucket).

Once the drawer is emptied, put in back in place by performing the previous step in reverse.

6.1.3. Cleaning the refractory material walls (ALUTEC®)

They do not require any cleaning, since the feature of this material (ALUTEC fire box is hot. After the lighting phase, during which they tend to blacken, the refractory materials will turn white again, starting from the base of the flame, when the combustion chamber reaches its operating temperature (~ 400° C).

If this does not happen, it may be due to the following:

• Humid or resinous wood that does not release enough heat or

• Flue pipe with poor performance resulting in smoke remaining

) is that it does not absorb soot but rather repels it when the

that dirties the combustion chamber

(see chapter 5.3)

too long in combustion chamber, dirtying the fire box.

INSTALLATION AND USE MANUAL

• Flue pipe with poor performance which does not allow fireplace

stove to reach high yield that results in adequate temperature of the refractory material.

Never clean the refractory material with a damp cloth or anything else, as it may be stained.

Use a dry paintbrush if necessary to remove heavy soot build-up.

If the Alutec does not whiten, it is not to be considered as a defect in light of the warnings and instructions above.

6.1.4. Lubrication and routine maintenance of the extensible guides

All of the doors of the fireplace stoves are mounted on extensible ballbearing guides that ensure a robust, sturdy system that provides silent movement.

Prolonged use and the heat of the fireplace stove gradually depletes the lubricant in the guides. This will cause them to become less efficient and noisier.

If necessary, periodically grease both runners as follows:

• Completely raise the door of the fire box so as to see the lower

parts (tracks) of the two guides.

• Using the provided grease gun, apply two drops of grease,

about 5 mm in diameter, at the highest visible point of the

runners. Do not exceed the recommended amount!

• Perform this operation on both guides. Keep in mind that the

total amount of grease to be used is about 0.5 ml (see graduated scale on grease gun).

After lubrication:

• Put the glue gun back and conserve it

• Lower and raise the door completely at least 6 or 7 times so

that the grease is spread onto all of the other components of the guides to complete lubrication. You should notice a substantial improvement in ease of movement and noise reduction.

It is advisable to carry out this operation at the end of the season of use, or whenever the runners become too noisy.

Do not use other types of grease. If the grease gun runs out, request an MCZ original replacement.

6.1.5. Maintenance of kit VF (if installed)

The maintenance of all electrical parts (fan, control unit, etc.) must only be carried out with no electrical power supplied and with the unit unplugged.

6.1.5.1.

Periodically, and at least at the end of each winter, it is advisable to clean the fan blades, which may have suctioned up dust or other small foreign bodies due to the static pressure exercised by the fan along the air ducts.

Clean the fan blades only with compressed air or with a vacuum cleaner. Take care not to damage the rotor or the fan blades.

Electric fan

Do not use any sort of rigid device which might bend the blades. When rotating, bent blades will produce more noise than normal due to off-axis rotation of the fan.
