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

INSTALLATION AND USE MANUAL

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. CONNECTION TO THE EXTERNAL AIR INTAKE

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) Useful 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

Up to 5 m

Over 5 m

900 (30x30 cm or ∅ 30 cm)

625 (25x25 cm or ∅ 25 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 !

In the event of doubt on your chimney flue operations or that its dimensions are different from those recommended, we highly suggest an authorised MCZ technician inspect and measure chimney flue performance (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.

system to adopt.

FORMA can distribute hot air either by NATURAL CONVECTION (VN) or by FORCED CONVECTION (VF) through the use a forced

ventilation.

Example of fireplace stove packing

INSTALLATION AND USE MANUAL

4.2.1. Natural convection (VN)

If it is decided to opt for this system, the knockout panels in the

sides and on the back of the unit (as shown in

figure 1

) must be

removed in order to facilitate heat exchange and air circulation.

The upper knockout panels are circular, Ø 150 mm. At least two of them should be opened and ducted for correct distribution of warm air. To open the knockout panels, hit them with a rubber mallet and

remove the profile that detaches from the unit.

4.2.2. Forced convection (VF)

If you adopt this system, purchase the optional Comfort Air kit and follow the instructions in

paragraph 5.3 “Installation of comfort air kit".

Chapter 4

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

figure 2

from both sides of the fireplace stove.

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.

4.4. POSITIONING

The FORMA 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.

To make it easier to move the unit to its place of installation, MCZ provides four swivel castors that make moving the fireplace stove easy and convenient.

The four castors, which you will find in the fire mouth along with the rest of the equipment, are to be installed in the provided holes, located near the holes for the adjustment feet (figure 3b). Once the fireplace stove is in place, the castors must be raised off the ground or removed, so that the unit is stable on the floor.

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.

For installation near flammable material, comply with the following minimum safe distances: (Figure 3c)

(Figure 3a)

Figure 1 – Forma Line knockout panels

Figure 2 – Screw to hold counterweights

5 cm min.

1 cm

Figure 3a – Distance of unit from walls and from cladding

INSTALLATION AND USE MANUAL

• A = 100 mm (distance from the sides and back)

• B = 80 mm (height above floor)

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

The hot air outlets must be placed at least 300 mm

from other materials. (e.g. curtains)

4.5. ADJUSTMENT OF HEIGHT AND BALANCING

Chapter 4

page

The Forma Puro fireplace stove is provided with adjustment feet that

are to be screwed into the unit after you have decided its exact position. Their purpose is to distance the stove unit from the floor and

to level the fire bed of the fireplace stove. They allow adjustment of about 10 cm.

If you want to raise the fireplace stove more than 4 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.

In the VF forced ventilation configuration (i.e. with fan), you will need to add the legs in the kit. Their purpose is to raise the fireplace stove as shown in

figure 5b.

On the legs, you will need to install the provided

feet to adjust the level as described previously.

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

If the floor is made of flammable material, the lower

part of the fireplace stove must be kept at least 8 cm from the floor.

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.

CHECK THAT THE DOOR MOVES CORRECTLY SEVERAL TIMES BEFORE ENCLOSING THE FIREPLACE STOVE IN THE CLADDING.

INSTALLATION AND USE MANUAL

4.6. EXTERNAL AND INTERNAL AIR INTAKE

4.6.1. Combustion air inlet

The FORMA fireplace stove is set up with two side holes Ø 100 mm, already opened, for the entry of air required for combustion.

Connect by flanges ø100 and hose at least one of the combustion air inlets (fig. 4) grilles inside or outside the room of installation so that the path is separate from the air of natural or forced convection.

NEVER CLOSE OFF THE COMBUSTION AIR INTAKE HOLES.

WHEN INSTALLING THE CLADDING, MAKE SURE THAT NONE OF ITS PARTS OBSTRUCT THE AIR INTAKES

CONNECT AT LEAST ONE OF THE TWO DUCTS AND

ALWAYS RUN IT OUTSIDE THE CLADDING OF THE FIREPLACE STOVE. IF YOU DO NOT COMPLY WITH THIS RULE, THE COMFORT AIR KIT MAY DRAW IN THE AIR INTENDED FOR COMBUSTION

4.6.2. Air inlet for natural ventilation

Figure 4 – Combustion air intakes.

Chapter 4

page

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 5)

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

4.6.3. Air inlet for forced ventilation

4.6.3.1.

If the fireplace stove is installed with forced ventilation, i.e. using the Comfort Air kit, place air intakes and ducts as follows:

for proper air circulation in the room, it is advisable to arrange one

external air intake A of 150 cm², in order to draw in clean, fresh

air; place the other B in the room where the fireplace stove is

installed (also of 150 cm²).

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

If you cannot make this kind of connection, you will still need to arrange both air intakes, 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.

INSTALLATION AND USE MANUAL

Remember that:

• All of the air intakes must be equipped with shutters than can

be controlled from the outside and that are equipped with insect protection.

• The air intake section is considered net, therefore the area of

any obstructions must be considered (mesh, etc.)

• The filters or meshes need to be cleaned periodically to ensure

air can pass through them.

• Do not for any reason obstruct the air intakes if the fireplace

stove or ventilation kit is in operation

INSTALLATION AND USE MANUAL

4.7. 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.

(figure

4.8. INSTALLATION OF CLADDING AND HOOD LINER

Chapter 4

page

Figure 7 – Connection to the flue pipe

BEFORE YOU START INSTALLING THE CLADDING OF THE FIREPLACE STOVE, READ CHAPTER 6.2 “OPERATING TEST”

The fireplace stove and the parts of the cladding must be attached to

one another WITHOUT COMING INTO CONTACT WITH THE STEEL STRUCTURE to prevent transmission of the heat to the marble

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.

(figure 8)

4.9. INSULATING A WOODEN BEAM

The wood beam must be protected with adequate insulation from heated parts to prevent the risk of fire or damage of the cladding.

4.10. 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.).

Hood ventilation nozzles.

You must

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

MCZ non risponde di eventuali danni alla struttura o alla componentistica elettrica causati dalla mancata osservanza di questa avvertenza.

For proper operation of room ventilation remember that:

• In the lower part of the cladding, an opening for the entry of

convective air must be provided that is not smaller than 400

• In the upper part it is necessary to provide a vent opening (in

addition to the ducted air outlets) of at least 230 cm

to release into the room the residual heat that accumulates inside the cladding. With the COMFORT AIR kit, however, this outlet is not necessary, because the heat in the cladding is indirectly drawn in by the fans.

•

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.

1a) Grille for convection air outlet 1b) Grille for intake of convection air

Grilles 1a and 1b are essential for releasing the heat that builds up in the hood. They must be installed, regardless of

the type of installation or cladding to be realized.

Before installing the natural or forced ventilation COMFORT AIR kit, make sure you have the following material available (fig.1):

1. For natural ventilation: connect the hoses (a) and the

flanges (d) Ø 150

stove unit (fig.1).

For forced ventilation: connect the flanges (d) and the hoses (a) Ø 100

stove unit. Forced ventilation uses hoses with a smaller diameter than those used for natural ventilation.

2. prepare on the wall (f) at the desired height two holes for the

hot air outlets measuring 185 mm x 185 mm

3. Insert the structure of the selected outlet (g) in the holes of

185 x 185 mm, working from the outside towards the inside of the wall

4. on the inner part of the wall, at the structure of the air outlet

(1), attach the fastening bracket group (2), using the four

screws and nuts provided (fig.2)

5. connect the hose (a), previously fastened to the fireplace hose,

to the connection located on the structure of the air outlet (e)

6. tighten the hose (a) on the connection (e) with the provided

clamp (c)

7. before the cladding is complete connect the electrical

cables of the light and/or fan, since everything to be done afterwards can be done form the outside.

• Limit the ducting to 2 linear metres for natural

ventilation, and 8 linear metres for forced ventilation.

• For natural ventilation, it is advisable to position the air

outlets at a height of not less than 2 m above the floor. (fig.3).

• For forced ventilation, the kit can also be positioned at a

certain distance from the fireplace stove (max 8 m). In this case, you must properly insulate the ducts dispersed and heats only the masonry.

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

different quantities of air at different outlets.

• For both natural and forced ventilation, it is advisable to

duct the front air outlets (A) where more heat accumulates than at the rear outlets (P).

5.3.1. Variation for air outlet with container

The essence container (2) is available only on the one-direction air

outlet with and without light. Its purpose is to humidify the air.

The container (2) can easily be removed from its seat. To do so, lift the door (1) at the bottom and extract the container (see fig.4).

Place only water in the container. It is possible to add essences to

perfume the room.

IMPORTANT! EXTRACT THE CONTAINER FROM ITS SEAT FOR

FILLING ONLY WHEN THE AIR OUTLET IS COOL AND THE STOVE UNIT IS OFF.

5.3.2. Variation for air outlet with illumination

If you decide to install the ventilation kit with illumination, you must remove the knockout panel located on the structure of the air outlet

(fig.5) and pre-install the light (a).

To open the pre-cut knockout panel, strike it with a rubber mallet. (fig.5).

Install the light (a) on the structure of the air outlet at the knockout

panel so that it is facing the front of the structure (fig. 6). Fasten the

light using the two brackets (c) with the screws (b) and bolts (d)

provided.

Once you have inserted the light (a), make the electrical connections.

In the rear part, insert the two female terminals on the tips of the light (fig.7)

For forced ventilation, you will need to connect the power cord of the light (included) to the control unit in the appropriate terminal. For

natural ventilation, the connection must be made to a wall switch (to be done by the installer).

The cable provided for connection of the light is 2.5 metres. For greater lengths you will need to use an extension cord.

IMPORTANT! The cable for the connection of the light/fan is made

of silicone material to withstand high temperatures. If you use extension cords (over 2.5 m) or in any other circumstance, make sure that the cord does not come into contact with the hot parts of the stove and of the air connection hoses in the cladding of the structure.

If you install the comfort air kit with illumination, it is necessary to pre-install the light on the kit before inserting it in the hole.

5.5.2. Operation

Activation of the fan is signalled by LED 2

AUTOMATIC mode (AUT LED on 4a)

The AUT is generally used to turn off the fan.

For example, in the evening you can load wood for the last time

and turn the selector to AUT. The fan, with the consent of the

probe, will continue to provide hot air until the temperature drops. In this way, you will keep the room comfortable all night long. The next morning, the fire box will contain embers ready for a new load of wood or it will be out.

INSTALLATION AND USE MANUAL

MANUAL mode (MAN LED on 4b)

The fan runs at the selected speed independently of the temperature measured by the sensor. When the stove unit is

turned on, on the control unit place selector 4 in manual 4b. The speed of the fan is set using the knob (3).

With the knob turned completely to the left, the fan is off as is

the indicator light (1). Turn the knob to the right to change from “OFF” to “ON” (indicator light 1 on). If you continue

turning the knob to the right, the speed of the fan will gradually

increase (indicator light 2 on).

In manual mode, the fan will operate in a mode regardless of

the probe, and will therefore be controlled by the knob (3)

5.5.3. Safety function

When knob 3 is in the off position, the safety function is active. If the temperature probe reaches the safety threshold, the

6. OPERATION

6.1. 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!

Chapter 6

page

6.2. 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

7.1.4)

• Check that all of the wiring and the control unit

(if the kit COMFORT AIR 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 COMFORT AIR 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 6.

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.

6.2.1. 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.

• Completely open the front register of the combustion air using

the provided hook.

• 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.

Figure 10 – Maximum adjustment of combustion air opening

6.3. CHOICE OF FUEL

To obtain the maximum performance from your FORMA 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.

6.4. 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.

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.

6.5. LOADING THE FUEL

For normal fuel loading, open the fire door by lifting one of the handles as shown in

During use, the metallic structure, the handles 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 12

Nominal combustion has a duration of 50 min. Therefore, to obtain the nominal hourly loading set forth in the table in chapter 3, load the amount shown in parentheses in the table every 50 minutes.

. To close the door, do the opposite.

Figure 12 – Opening/closing the fire door

6.6. CONTROL OF COMBUSTION

PRIMARY AIR

The fireplace stove is equipped with two flanged side holes Ø100 mm for the inlet of primary air which ensures combustion and helps keep the glass clean.

. Moving the lever to the left provides the full aperture, and more rapid combustion, while moving it to the right closes the opening, with slower burning.

INSTALLATION AND USE MANUAL

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.

6.7. EMERGENCY SITUATIONS

Chapter 6

page

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.

7.1.2. Cleaning out the ashes

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

To remove the ashes from the fire bed, use a metal scoop and brush.

Place the ashes in a non-flammable container for transport.

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.

7.1.3. Cleaning the refractory material walls (ALUTEC®)

They do not require any cleaning, since the feature of this material (ALUTEC fire box is hot. During the lighting phase, during which the fire box tends 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

• Flue pipe with poor performance which does not allow fireplace

INSTALLATION AND USE MANUAL

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.

7.1.4. 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:

• Pull open the frame liner and extract the door so you can see

the tracks of the guide.

• 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 0.5ml (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.

7.1.5. 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.

7.1.5.1.

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.

7.2. CLEANING TO BE DEALT WITH BY SPECIALIZED TECHNICIAN

7.2.1. Cleaning flue pipe

Mechanical cleaning of the flue pipe is recommended at least once a year. Excessive deposits of unburnt solid material can cause problems with the evacuation of smoke, and gives rise to a risk of chimney fires. To clean the appliance's chimney, remove the smoke deflector. To remove it correctly, lift the front and at the same time slide it forward in order to free it from rear support.
