2. Theoretical notions for installation
2.1. Pellets
Wood pellets are manufactured by hot-extruding compressed sawdust which
is produced during the working of natural dried wood. The compactness of
the material comes from the lignin which is contained in the wood itself, and
allows the production of pellets without the use of glues or binders.
The market offers different types of pellet with characteristics which
vary depending on what mixture of woods is used. The diameter varies
between 6 mm and 8 mm, with a standard length in the range 5 mm to
30 mm. Good quality pellets have a density which varies between 600
kg/m3 and 750 kg/m3, with a moisture content which varies from 5%
to 8% by weight.
Besides being an ecological fuel (exploiting timber residues to the
maximum and achieving cleaner combustion than is possible with fossil
fuels), pellets also have technical advantages. While good-quality
timber has a calorific power of 4.4 kW/kg (with 15% moisture,
therefore after about 18 months' seasoning), the equivalent figure for
pellets is 5.3 kW/kg.
To ensure good combustion, the pellets must be stored in an area that
is free of humidity and protected from dirt. The pellets are usually
supplied in 15 kg. sacks, so storing them is very convenient.
Good quality pellets ensure good combustion, thus lowering the
emission of harmful agents into the atmosphere.
The poorer the quality of the fuel, the more
frequently will intervention be necessary for cleaning
the internal parts, such as the grate and the
combustion chamber.
The pellets must be produced from pure wood which has not been
treated chemically.
The standards DIN 51731 and ONORM M 7135 certify a high-quality
pellet with the following characteristics:
9 Calorific power: 5.3 kW/kg
9 Density: 700 kg/m3
9 Water content: max 8% of weight
9 Percentage of ashes: max 1% of weight
9 Diameter: 6 – 6.5mm
9 Length: max 30mm
9 Contents: 100% untreated wood, with no added bonding
substances (bark percentage 5% max)
9 Packaging: in sacks made from ecologically compatible or
biologically decomposing material
Fuel pellets
15 Kg sack of fuel

MCZ strongly recommends using certified fuel in its
stoves.
The use of fuel of inferior quality or not conforming
to the specification given above compromises the
running of your stove and can therefore lead to the
termination of the guarantee and of the
manufacturer's responsibility for the product.
MCZ pellet stoves run exclusively on pellets with a
diameter of 6 mm (only for Italy) and 6-8 mm
(European countries) with lengths that go from 5
mm to 30 mm.
2.2. PRECAUTIONS FOR INSTALLATION
IMPORTANTE!
THE INSTALLATION AND ASSEMBLY MUST BE
CARRIED OUT BY QUALIFIED PERSONNEL.
All local regulations, including those that refer to
national and European regulations, must be observed
at the time of installation of the unit
The stove must be installed in a suitable position to allow the normal
operations of opening and ordinary maintenance.
The site must be:
• capable of providing the environmental conditions for operation
• equipped with power supply 230V 50 Hz (EN73-23)
• capable of taking an adequate system for smoke discharge
• provided with external ventilation
• provided with an earth connection complying with CEI 64-8
IMPORTANT!
• THE PRODUCT MUST BE CONNECTED TO AN
INTERNAL OR EXTERNAL FLUE PIPE IN
COMPLIANCE WITH CURRENT STANDARDS.
• The product must be connected to a flue pipe or
other vertical smoke stack that can discharge
smoke at the highest point of the house.
• Smoke is generated from burning wood and,
therefore, may dirty adjacent or nearby walls.
Also take care because the fumes are very hot but
almost invisible, and can cause burns on contact.
• Before positioning the unit, a hole must be made
for the passage of the smoke pipe, and another
for the intake of air from outside.
• The electrical plug must be positioned where it is
always accessible. Otherwise, during installation,
provide suitable devices for disconnection for the
power supply network in compliance with
standards on electrical systems
Chapter 2
INSTALLATION AND USE MANUAL

2.3. OPERATING AREA
For proper operation the unit should be placed where air can flow that
is necessary for pellet combustion (this requires about 40 m
3
/h) in
accordance with the standard for installation and current national
standards.
The volume of the room must not be less than 50 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 in bedrooms,
bathrooms or showers, or in a room where another
heating appliance is installed (fireplace, stove etc.)
which does not have its own independent air intake.
Locating the stove in a room with an explosive
atmosphere is prohibited.
The floor of the room where the stove is to be
installed must be strong enough to take its weight.
If the walls are not flammable, position the stove with a clearance to
the rear of at least 10 cm.
For flammable walls, keep a minimum distance of 20 cm at the rear, 50
cm on the sides and 150 cm at the front.
If the room contains objects which are believed to be particularly
delicate, such as drapes, sofas and other furniture, their distance from
the stove should be considerably increased.
If the flooring is made of wood, provide a floor
protection surface in compliance with current
national standards.
2.4. CONNECTION TO THE EXTERNAL AIR INTAKE
It is essential that at least as much air must be able to flow into the
room where the stove is installed as is required for proper combustion
in the appliance and for the ventilation of the room. This can be
effected by means of permanent openings in the walls of the room to
be ventilated, which give onto the outside, or by single or collective
ventilation ducts.
For this purpose, on the external wall near the stove, a hole must be
made with a minimum free cross-section of 100 cm². (equivalent to a
round hole of 12 cm diameter or a square hole 10x10 cm), protected by
a grille on the inside and the outside.
The air intake must also:
• communicate directly with the room where the stove is installed

Theoretical notions for installation Technical service - Rights reserved MCZ S.p.A. - Reproduction prohibited
• 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 REV.
2.5. CONNECTION OF SMOKE DISCHARGE PIPE
When making the hole for the passage of the smoke discharge pipe, it
is necessary to take into account the possible presence of flammable
materials. If the hole will be going through a wall made of wood or any
other material which is sensitive to heat, the INSTALLER MUST first
of all use the special wall union (diam.13cm 13cm minimum) and
properly insulate the pipe of the stove that passes through it, using
adequate insulation materials (thickness 1.35cm with minimum thermal
conductivity of 0.07 W/m°K).
The same is true if the stove pipe must run through vertical or
horizontal stretches passing in proximity (min.20cm) to the heatsensitive wall
As an alternative we recommend the use of insulated pipe, which can
also be used on the outside to avoid condensation.
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.
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
• THE TUBE Ø 80 mm IS NEEDED ONLY TO

2.6. CONNECTION TO THE FLUE PIPE
The flue pipe must have internal dimensions not larger than 20 x 20
cm, or diameter 20 cm. In the event of larger dimensions, or of the
flue pipe being in poor condition (for example cracks, poor insulation,
etc.), it is advisable to fit a stainless steel pipe of suitable diameter
inside the flue pipe throughout its length, right up to the top.
Check with suitable instruments that there is a minimum draught of 10
Pa.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.
2.7. CONNECTION TO AN EXTERNAL FLUE WITH
INSULATED OR DOUBLE-WALL PIPE
The external fluepipe must have internal dimensions of minimum
10x10 cm or 10 cm diameter, and maximum 20x20 cm or 20 cm
diameter.
Check with suitable instruments that there is a minimum draught of 10 Pa.
The only type of pipe which is permissible is insulated (double-walled)
stainless steel, smooth on the inside, fixed to the wall. Flexible stainless
steel pipe must not be used. At the bottom of the flue pipe, provide an
inspection cap to allow periodic checking and cleaning, which must be
done annually. Make a gas-tight connection to the flue pipe, using
pipes and connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power cut.
2.8. CONNECTION TO THE FLUE PIPE
For proper functioning, the connecting pipe between the stove and the
chimney or flue duct must have a slope of not less than 3% in the
horizontal stretches, the length of which must not exceed 2/3
metres, and the vertical distance between one tee connector and
another (change of direction) must not be less than 1.5m.
Check with suitable instruments that there is a minimum draught of 10
Pa.
At the bottom of the flue pipe, provide an inspection cap to allow
periodic checking and cleaning, which must be done annually.
Make a gas-tight connection to the flue pipe, using pipes and
connectors as recommended by us.
You must ensure that a windproof cowl should be fitted which complies
with the standards in force.

2.9. OPERATING PROBLEMS CAUSED BY DRAUGHT
DEFECTS IN THE FLUE
Of all the weather and geographical conditions which affect the
operation of a flue pipe (rain, fog, snow, altitude a.s.l., exposure to
sunlight, direction of facing), the wind is unquestionably the most
decisive. In fact, along with thermal depression caused by the
difference in temperature inside and outside of the chimney, there is
another type of depression or over-pressure: dynamic pressure caused
by the wind. An updraft always increases depression and hence
draught. A crosswind increases depression provided the cowl has been
installed properly. A downdraft always decreases depression, at times
inverting it.
Besides the direction and force of the wind, the position of the flue and
the cowl with respect to the roof of the building and the surrounding
landscape is important.
The wind also influences the operation of the chimney indirectly by
creating high-pressure and low-pressure zones, not only outside the
building but inside as well. In rooms directly exposed to the wind (2),
an indoor high-pressure area can be created which can augment the
draught in stoves and fireplaces, but it can be counteracted by the
external high pressure if the cowl is situated on the side exposed to the
wind (1). On the other hand, in the rooms on the opposite side from
the direction of the wind (3), a dynamic depression can be created
which competes with the natural thermal depression developed by the
chimney, but this can be compensated for (sometimes) by locating the
flue on the opposite side from the direction of the wind (4).
IMPORTANT!
The operation of the pellet stove is noticeabl
y
sensitive to the conformation and position of the flue
which is adopted.
Hazardous conditions can only be overcome by
suitable setting-up of the stove carried out by
qualified MCZ personnel.

3.2. PREPARATION AND UNPACK ING
The unit is delivered in a single package.
Open the packaging, take off the bands, remove the stove unit from
the pallet and position it in the chosen location, taking care that its
position complies with the above instructions.
The stove body or unit must always be kept in a vertical position when
moved, and moved only using carts. Special care must be used to
protect the door and the glass from impacts that would damage them.
Moving the product must always be done with care. If possible, unpack
the stove in the area where it is going to be installed.
The materials which make up the packaging are not toxic or harmful,
so no special procedures for disposal by required.
Their storage, disposal or possible recycling are therefore the responsibility
of the final user, in compliance with current legislation on the subject.
Do not store the stove unit or its cladding without their packaging.
If the stove needs to be connected to a discharge pipe which goes
through the rear wall (to connect up with the flue), take the greatest
care to make sure that the joint is not stressed.
Use the four adjustable feet (J) to get the stove correctly levelled so
that the smoke outlet (S) is lined up with the connecting pipe (H) .
3.3. MOUNTING TO THE UNIT BASE
You must anchor the unit to the floor because during annual
maintenance by an authorized technician, the combustion chamber may
be removed from its seat via the two extensible guides.
To mount the unit base, proceed as follows:
1. Measure the distance (A) from the exterior striker to the
exterior support to position it correctly.
2. Remove the compensation frame or the right and left elements
(C) as indicated in section 3.4
3. Unscrew the bottom screws (B) beneath the unit door.
4. At this point, take out the machine and separate it from the
support (D).
5. Position the support (D) at the previously measured distance
from the wall (A).
6. Use the provided screws to mount the support (D) to the base
(E).
It is mandatory to mount the unit to the base, since
during maintenance the combustion chamber must be
extracted, causing the barycentre of the equipment to
shift forward. If the product is not anchored to a
surface, it runs the risk of loosing its stability.

The unit can be installed at the desired level, creating a structure of the
opportune height. This support must be constructed in inflammable
material.
MCZ declines any responsibility for possible damages
to persons or things if the aforementioned warnings
are not respected.
3.4. REMOVAL OF COMPENSATION FRAME
To avoid damage to the border frame (C) located around the fire door,
it is recommended to remove it before mounting the Powerbox to the
base (E) and to put it in a safe place. For removal, see
chap. 3.13
3.5. INSTALLATION OF PELLET LOADING CHUTE
(LINK)
Before positioning the unit, you will need to decide on which side the
chute for fuel loading will be installed.
The Powerbox Link is provided with two straps, the connecting tube
and the chute with a small door.
The chute can be assembled on the right side, the left side or on the
front. The connecting tube is one meter long.
It is mandatory to shorten the connecting tube in
accordance with its position (side or front) in a way
that results in the tube being firmly extended. This
operation is necessary to facilitate pellet descent.
Before assembling the cladding, execute a test by
loading the combustible fuel to make sure that the
pellets descend correctly towards the hopper.
