PELLET STOVES Chapter 2
INSTALLATION AND USE MANUAL
2. THEORETICAL NOTIONS FOR INSTALLATION
2.1. PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust
which is produced during the working of natural dried wood. The
compactness of the material comes from the lignin which is contained
in the wood itself, and allows the production of pellets without the use
of glues or binders.
The market offers different types of pellet with characteristics which
vary depending on what mixture of woods is used. The diameter varies
between 6 mm and 8 mm, with a standard length in the range 5 mm to
30 mm. Good quality pellets have a density which varies between 550
3
to over 700 kg/m3, with a moisture content which varies from
kg/m
5% to 8% by weight.
With the aim of guaranteeing the stated rate of fuel
consumption per hour and ensuring optimum combustion, MCZ
has devised a patented method which allows the identification
and cataloguing of any type of pellet with a 6 mm and 8 mm
diameter, in terms of its specific gravity and particle size.
By using the special PelletBox® and following the procedure set out in
the paragraph on lighting the stove, the user can determine the correct
settings for configuring the stove.
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, 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/m
9 Water content: max 8% of weight
9 Percentage of ashes: max 1% of weight

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.

PELLET STOVES Chapter 2
INSTALLATION AND USE MANUAL
2.2. OPERATING AREA
For proper functioning and good temperature distribution, the stove
should be positioned in a location where it is able to take in the air
necessary for combustion of the pellets (about 40 m
available), as set forth in the standard governing the installation and in
accordance with local national standards.
The volume of the room must not be less than 30 m
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 strict compliance with the provisions
of current standards.
It is not permissible to install the stove 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 support its
weight.
If the walls are not flammable, position the stove with a clearance to
the rear of at least 10 cm.
In the case of walls made of flammable material, maintain a minimum
clearance to the rear of 20 cm, a clearance to the sides of 50 cm, and a
clearance to the front of 150 cm. If the room contains objects which
are believed to be particularly delicate, such as curtains, 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.

INSTALLATION AND USE MANUAL
2.3. PRECAUTIONS
IMPORTANT!
Installation and assembly of the stove must be
carried out by qualified personnel.
The stove must be installed in a suitable position to allow the normal
operations of opening and ordinary maintenance.
The site must be:
• capable of providing the environmental conditions for operation
• equipped with power supply 230V 50 Hz (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
The stove must be connected to a flue pipe or an internal or
external vertical duct conforming to current standards UNI
7129 - 7131 9615.
The stove must be positioned in such a way that the electrical
plug is accessible.
IMPORTANT!
The stove must be connected to a flue pipe or a
vertical duct which can discharge the fumes at the
highest point of the building.
The fumes are however derived from the combustion
of wood products, and if they come into contact with
or close to walls, they can make dirty marks.
Also take care because the fumes are very hot but
almost invisible, and can cause burns on contact.
The holes for the passage of the smoke pipe and for
the intake of air from outside should be made before
positioning the stove unit.
page
14
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 conduits.
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
• be protected by a grille, metal mesh or suitable guard, as long as
this does not reduce the cross-section below the minimum.
• be positioned in such a way as to be impossible to obstruct
It is not compulsory to connect the air inlet of the
stove directly with the exterior, but an air flow must
be guaranteed of at least 50 m³/h. Refer to current
standards.

INSTALLATION AND USE MANUAL
2.5. CONNECTION OF SMOKE DISCHARGE PIPE
page
15
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 minimum) and properly
insulate the pipe of the stove that passes through it, using adequate
insulation materials (thickness 1.3 - 5cm with minimum thermal
conductivity of 0.07 W/m°K).
The same is true if the stove pipe must run through vertical or
horizontal stretches passing in proximity (min. 20cm) to the heatsensitive wall.
As an alternative we recommend the use of insulated pipe, which can
also be used on the outside to avoid condensation.
The combustion chamber works in low pressure. The smoke duct for
the discharge of fumes will also be under low pressure when connected
to an efficient flue pipe as directed.
Pipes and unions with suitable gaskets must always
be used, to guarantee a hermetic seal.
All sections of the smoke duct must be inspectable and
removable to enable periodic internal cleaning. Tee
connectors with inspection caps should be used.
Position the stove bearing in mind all the instructions and
considerations above.
IMPORTANT!
All 90 degree changes of direction in the flue pipe
must be fitted with suitable tee connectors to allow
the possibility of inspection (see the pellet stove
accessory list).
It is absolutely prohibited to fit a grille on the end of
the smoke discharge pipe, because it could lead to
poor operation 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
NOT ADVISABLE TO EXCEED A LENGTH OF 6 LINEAR
METRES OF PIPE Ø 80 mm.

2.6. CONNECTION TO THE FLUE PIPE
page
16
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.
Figure 9
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 is fitted which complies with
current standards.
This type of connection ensures the evacuation of the
fumes even in the event of a temporary power
outage.
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.
Figure 10
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.

2.9. 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.
Least favourable points
WIND
High-pressure
Besides the direction and force of the wind, the position of the flue and
the cowl with respect to the roof of the building and the surrounding
landscape is important.
The wind also influences the operation of the chimney indirectly by
creating high-pressure and low-pressure zones, not only outside the
building but inside as well. In rooms directly exposed to the wind (2),
an indoor high-pressure area can be created which can augment the
draught in stoves and fireplaces, but it can be counteracted by the
external high pressure if the cowl is situated on the side exposed to the
wind (1). On the other hand, in the rooms on the opposite side from
the direction of the wind (3), a dynamic depression can be created
which competes with the natural thermal depression developed by the
chimney, but this can be compensated for (sometimes) by locating the
flue on the opposite side from the direction of the wind (4).
IMPORTANT!
The operation of the pellet stove is noticeabl
sensitive to the conformation and position of the flue
which is adopted.
Hazardous conditions can only be overcome by
suitable setting-up of the stove carried out by
qualified MCZ personnel.

2.10. PLUMBING CONNECTION
IMPORTANT!
The connection of the stove to the plumbing system
must be carried out ONLY
who are capable of carrying out installation properly,
in compliance with current standards in the country
of installation.
If installation of the stove will involve interaction
with another, pre-existing system complete with
heating equipment (gas boiler, methane boiler, fuel
oil boiler, etc.), it is even more advisable to call in
qualified personnel, who subsequently will be
responsible for conformity of the system with current
applicable law.
MCZ will not be held responsible for damage to
persons or things in the event of failed or incorrect
operation if the aforementioned warnings are not
complied with.

3.2. PREPARATION AND UNPACKING
Polar and Nova stoves are delivered in two packages:
9 The first contains the stove unit (
9 The second contains the ceramic cladding. (
The Athos stove is delivered only with the packaging in fig. 1.
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 main stove unit must always be moved in an upright position and a
trolley must always be used. Take particular care to see that the door
and its glass are protected from mechanical impact which could
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.
If the smoke outlet of the stove is forced or used
improperly to lift it or position it, the operation of the
stove can be damaged irreparably.

INSTALLATION AND USE MANUAL
3.4.1. Connections to the system
Make the connections to the corresponding fittings shown in the
diagram on the previous page. Make sure the pipes are not placed
under tension or undersized.
IMPORTANT
IT IS STRONGLY RECOMMENDED TO WASH THE
ENTIRE SYSTEM BEFORE CONNECTING IT IN ORDER
TO GET RID OF RESIDUES AND DEPOSITS.
Upstream from the stove, always install shutters so
as to disconnect it from the plumbing system should
it be necessary to move it, or when it requires
routine and/or special maintenance.
Connect the stove using hoses so that the stove is
not too strictly connected to the system, and to allow
slight movements.
The pressure discharge pipe should be tentatively
placed in a pitcher or funnel to keep water from
wetting the floor or the structure in the event of
excessive pressure.
Pressure discharge pipe (3 bar)
page
28
3.4.2. System filling
To fill the system, the stove is equipped with a tap (D), with a nonreturn valve, for manual filling of the heating system. During this
operation, any air in the system is released by the automatic vent valve
at the upper left of the boiler body (under the ceramic top).
To ensure the valve vents correctly, it is advisable to loosen the grey
cap one turn and to keep the red cap blocked
(see figure)
The filling pressure of the system WHEN COLD must be
1 bar.
During operation, if the system pressure drops (due to evaporation of
dissolved gases in the water) to values lower than the minimum
indicated above, the user must use the filling valve to bring the
pressure back up to its normal pressure.
For proper operation of the stove WHEN HOT, the pressure in the
boiler must be 1.5 bar.
To monitor the pressure of the system, install down the line
from the bibcock (D) a pressure gauge with a scale of 0-5 bar.
This is to be done by the installer.
Upon completion of this operation, always close the tap.
3.4.3. Water characteristics
The characteristics of the water used to fill the system are very
important to prevent the build-up of mineral salts and the formation of
incrustations along the pipes, in the boiler and in the heat exchangers
(especially plate heat exchangers for the heating of domestic water see chapter 4.13)

• Hardness of water circulating in the system, to prevent
problems of incrustation and limescale, especially in the
domestic water heat exchanger. (> 25° French)
• Installation of a water softener (if water hardness
exceeds 25° French)
• Filling the system with treated water (demineralised).
• Possibly providing an anti-condensation circuit.
• Installation of plumbing bumpers to prevent banging
along the fittings and pipes.
If you have very extensive systems, with a large amount of water, or
which require frequent refilling, the installation of water softening
systems.
It should be remembered that incrustations
drastically reduce performance due to low thermal
conductivity.

3.6. OPENING/CLOSING OF ATHOS STOVE DOOR
The Athos stove is equipped with an Allen key for the opening/closing
of the door; just insert the key, exert light continuous pressure towards
the door and rotate the handle (anticlockwise to open and clockwise to
close the door).
The door is closed when the key will not turn any further. It is normal
for this operation to require the key to be turned 180° several times.
ATTENTION!
In order for the stove to operate correctly, it is
essential that the door be closed completely. Turn the
key clockwise until it will clearly not turn any further.
3.7. MAKING THE ELECTRICAL CONNECTIONS
Connect the supply cable first at the rear of the stove and then to an
electrical outlet on the wall.

rear of the stove should be switched on only when you want to light
the stove.
If you do not intend to use the stove, it is advisable to keep it
switched off.

4. OPERATION
4.1. PRE-LIGHTING WARNINGS
ATTENTION!
Installation is to be made only with connection to a
flue pipe. Therefore, the following evaluation criteria
for identification of installation are to be considered
compliant with standards.
For complex or articulated installations, we
recommend you contact specialized personnel or
authorized MCZ service centres.
MCZ does not recommend other types of installation,
where smoke is not discharged into a flue pipe, and
will not be held liable for any malfunctions or
anomalies.
• Do not touch the stove during the first lighting, as it is
during this phase that the paint sets. If you touch the
paint, you may expose the steel surface.
• If necessary, touch up the paint with the aerosol spray in
the original colour (see the section "Accessories for pellet
stoves").
• It is good practice to provide plenty of ventilation in the
room during the initial lighting, as the stove will give off a
small amount of smoke and smell of paint.
• Do not stay near the stove, and as previously mentioned,
ventilate the room. The smoke and the smell of paint will
vanish after about one hour of operation. There are no
health risks involved.
• Make sure the plumbing system is sealed perfectly and
that there are no leaks or pressure drops.
• Make sure that all cut-off valves between the stove and
the system are open.
• Make sure you have vented all air out of the system
before start-up.
• Make sure that internal devices work properly (flow
switches, thermostats, etc.). Make sure that the
combustion chamber and the flue pipe are clean, and that
the plumbing circuit is free of obstructions.
The stove will be subject to expansion and
contraction during the stages of lighting and cooling
down, and may therefore make slight creaking noises.
This phenomenon is absolutely normal, the structure
being made of sheet steel, and must not be
considered a defect but rather a characteristics.

INSTALLATION AND USE MANUAL
4.2. PRE-LIGHTING CHECK
Check that all the safety conditions described above have been met.
Make sure you have read and completely understood the contents of
this instruction booklet.
Remove all components from the firebox of the stove
and from the door. They may catch fire otherwise. This
includes the instruction booklet and various stickers.
Check that the grate for pellet combustion is correctly positioned, rests
properly on the base, and that it has not moved during handling of the
product.
Check that the electrical connection is correct (230 V 50 Hz), and turn
on the main switch located on the rear panel of the stove.
Check that on the control panel the display is lit up with the message
OFF / "CURRENT TIME".
4.3. LOADING THE PELLETS
page
34
Fuel is loaded from the upper part of the stove by opening a door. Pour
the pellets in the hopper. When empty, it will hold about two 15-kg
sacks.
This is easier if performed in two steps:
• Pour half of the contents into the hopper and wait for the fuel
to settle on the bottom.
• Then pour in the rest
Never remove the protective grille from inside the
hopper. When loading pellets, keep the bag from
coming into contact with hot surfaces.

r.
After repeated ignitions, if no flame appears even though there is a
correct supply of pellets, there may be a problem with the components
of the stove or installation may not be correct.
REMOVE THE PELLETS FROM THE BURNER AND
CONTACT AN AUTHORISED MCZ TECHNICIAN.
4.8.2. Extinguishing the stove
page
38
The stove can be extinguished at any time and in any position.
To extinguish the stove, press the key
r for several seconds.
NEVER SHUT THE STOVE DOWN BY CUTTING OFF THE
ELECTRICITY SUPPLY: Always let it complete the
shutdown cycle, otherwise damage could be caused
to the structure, and also problems with lighting in
the future.
4.9. VIEW OF THE FLAMES
In order to get proper operation from the stove, you need to be able to
interpret the appearance of the flame. Characteristics which the user
should take into consideration are basically the following:
• The shape
• The colour
• The character
4.9.1. The shape
In normal combustion the flame should have a tapered shape, a
lively character, with the tips of the flames basically vertical or pushed
towards the back of the firebox. You should get the impression that the
flame is being drawn upwards.
Conversely, a flame which swells outwards at the base, with a thin
character, with a point that appears to wander, could be a symptom of
bad setting as regards loading of the fuel and/or extraction of the
fumes, or could indicate that the flue is obstructed or that there are
down-draughts which impede the proper evacuation of the smoke.
In this case there will ALWAYS be operating problems. Request
assistance from specialized personnel or advice from MCZ technicians.

PELLET STOVES Chapter 4
INSTALLATION AND USE MANUAL
4.9.2. The colour
The colour is in some ways linked to the shape of the flame. A colour
which varies from orange to yellow, with dark tips to the flame, is liable
to be a swollen flame (as described above), lacking in oxygen or at
least indicative of faulty combustion. As the colour changes towards
light yellow - white, the shape of the flame alters, becoming thinner
and showing the presence of higher levels of oxygen.
4.9.3. The character
Liveliness or weakness is in any case closely connected to the shape of
the flame.
4.10. OPERATION
4.10.1. Operating concept
When you light the stove using the button r, after the initial ignition
phase of about 15 minutes, during which the display (8) shows the
intermediate phases “FAN ACC – LOAD WOOD – FIRE ON“, the stove
will start running in AUTOMATIC mode at medium power, and it will
make a first check of the temperature to be reached.
The ambient temperature is shown on the upper display (8) of the
panel, whereas the temperature of the water in the boiler is indicated
on the lower one alternating with the message H
In this operating mode, you can vary only the desired room
temperature using the buttons
n and o.
The main purpose of the stove is to bring the room
temperature as measured by the thermostat (internal or
external) up to the temperature set by the user.
Then, based on the room temperature, it performs the
following evaluation:
Room temperature < Thermostat temperature ?
• YES
This means that the stove must heat the room. Therefore, it will
begin gradually raising its flame power until it is at its maximum.
• NO
This means that the stove has achieved its objective in heating the
room. Therefore, it will decrease its power to a minimum, and it
will leave it there until the room temperature again drops below
the temperature set in the thermostat, unless the ECO-STO
function is enabled (see paragraph 4.9.3)
For proper operation, it is indispensable for the room
thermostat (internal or external) to measure the
temperature reliably, since the correct operation is
based almost exclusively on the aforementioned
control.

4.10.2. Operating modes
The AUTOMATIC mode lets you set a certain temperature to be
reached. In this operating mode the stove will automatically vary the
thermal power provided so as to keep the temperature in the room
constantly at the previously set value.
As previously described, the temperature is adjusted using the buttons
n and o, in steps of 1 degree centigrade.
Also front ventilation, which is active in automatic mode only when the
stove is hot, is divided into 5 speeds. It can be controlled using the
buttons
seconds on the display (8).
This setting will be maintained at the next lighting.
Operating example:
If the ambient temperature measured by the local probe on the stove is
15°C, and the temperature set on the thermostat is 22°C, the stove will
sequentially go to maximum power. Upon reaching the requested fixed
temperature (22°C), the stove will go back to minimum power or it will
enter ECO-STOP mode
It must be remembered however that the temperature keyed into the
thermostat is only indicative, and it is up to the user to find the correct
setting in the location where the stove is installed (for example, to
achieve 22°C in the room, it may be necessary to set the thermostat on
the stove to 20°C). This is because the ambient thermostat is located
near the body of the stove; therefore, it detects the heat radiated from
the stove.
In this mode, lighting and shutdown are performed by the user, by
pressing button
It is advisable to inspect the contents of the hopper from time to time,

INSTALLATION AND USE MANUAL
4.10.2.1. Internal thermostat - Position of internal room sensor
Only when installation is complete, be sure to check that the
room probe is removed from its place and set far away from
the stove, to prevent it from detecting incorrect temperatures.
The probe is located on the back part of the stove.
When you use the internal thermostat, you should always set a
temperature that is a few degrees higher (for example, if you want to
attain 20°C you should set to 22°C) because the probe is affected by
the heat from the body of the stove.
4.10.2.2. Operation by means of external thermostat
EXTERNAL THERMOSTAT (not included with the stove, to be
provided by the user)
The temperature of the stove can also be controlled by an external
room thermostat. It is located in a central position of the room where
the stove is installed. It provides a closer match between the heating
temperature requested of the stove and what it actually provides.

4.10.2.3. Connection of external thermostat
Connect the two wires coming from the wall-mounted thermostat to the
terminal of the MCZ connector.
Insert the connector in the socket located on the back of the stove.
Figure 7
Once the thermostat is connected, you will need to
disconnect the internal thermostat that the stove is
equipped with.
In order to do this, proceed as follows:
• Press the button

control panel. The display of the control panel will show the
message UT01/OFF
• Press the button

n or o , set this parameter to “ON” or “OFF”. If
it is set to “ON”, the internal thermostat is enabled. Conversely, if it
the parameter is set to “OFF”, the external thermostat is enabled
and the internal one is disabled.
• Therefore, if you need to enable the external thermostat, you will
need to set parameter “UT20” to “OFF”.
To exit the menu, press the button

4.10.3. Setting of ECO-STOP mode
The thermostat manages stove operation by shutting the stove
down once the set temperature is reached and then lighting
again when this is necessary.
You can activate or de-activate this function, or select the intervals with
which the stove is to shut down.
Operation Technical service - Rights reserved MCZ S.p.A. - Reproduction prohibited
PELLET STOVES Chapter 4
INSTALLATION AND USE MANUAL
1st situation: ECO-STOP inactive (default)
If you de-activate this function, when the set temperature is reached,
the stove will continue operating at minimum power until power is
again requested by the thermostat or until the user decides to shut the
stove down manually.
The default setting for the stove is with ECO-STOP deactivated as in the previous example.
2nd situation: ECO-STOP active and time-controlled
If this function is activated, when the set temperature is reached the
stove will go to minimum for a time set by the user, which may be from
1 minute to 30 minutes. During this time, if there is no temperaturerelated request, the stove will then shut down automatically. The stove
will re-light automatically only if the thermostat requests heating.
Example with ECO-STOP active and time-controlled
If the room temperature measured by the thermostat probe (internal or
external) is 15°C and the temperature set on the thermostat is 20°C,
the stove will follow a pre-set ramp-up in power. Once the target
temperature is reached (20°C), the stove will go to minimum power.
The stove will remain in this mode for 15 minutes. If the room
temperature remains above the set temperature, the stove will
automatically shut down temporarily. The message “
Eco Stop
” will be
shown. When room temperature drops below the thermostat set value
(for example 18°C) the stove will prepare for automatic relighting
(“COOL-FIRE”). It will then start operating until a temperature of 20°C
is once again reached.
If the stove is equipped with the kit for the production of domestic hot
water, and hot water is requested for over 30 seconds (by means of
the flow switch), the stove will relight immediately without going
through the aforementioned cooling phases (“COOL-FIRE”)
All automatic relighting operations, either due to a
drop in room temperature or a request for hot water,
are possible if the stove is on or in ECO-STOP mode.
If the user shuts the stove down manually with the
button
r, the stove will not relight automatically
upon variation of the temperature or if hot water is
requested
If there is a kit for the production of domestic hot
water, you should disable the ECO-STOP mode in
order to reduce response times when hot water is
requested.
It must be remembered however that the temperature keyed into the
thermostat is only indicative, and it is up to the user to find the correct
setting in the location where the stove is installed (for example, you
need to set 22°C on the thermostat to attain an actual temperature of
20°C). In this mode, the user can light the stove by resetting the
thermostat to a temperature greater than room temperature, or by
pressing for a few seconds on the button
r. You will go to "Off" mode,
and then the same button is pressed to relight the stove.

IMPORTANT NOTE
The stove requires about 20 minutes before sufficiently warm
air comes out, and another 10 minutes before it is up to full
power. Take this into account when setting the start time.
Likewise, stove shutdown requires about 30 minutes, during
which the heat stored up by the stove is released into the
room. Keep this in mind for substantial fuel savings.
4.11. EXAMPLE OF PROGRAMMING
Here is a complete example of programming. It refers to a weekly
heating cycle in a home which is always inhabited, with the residents
coming home at lunchtime and in the late afternoon.
On weekdays, heating is desired first thing in the morning, during the
lunch break, and upon returning home from work. On weekends,
heating is to be in operation at all times.

4.12. SAFETY DEVICES
The stove is fitted with the following safety devices:
• PRESSURE SWITCH
Monitors pressure in the smoke duct. It is designed to shut down
the pellet feed screw in the event of an obstructed flue or
significant back-pressure (from the wind).
• SMOKE TEMPERATURE SENSOR
Monitors the temperature of the smoke, and gives permission for
startup or shuts the stove down when the smoke temperature falls
below the preset value.
• BULB TEMPERATURE PROBE OR CONTACT THERMOSTAT IN
THE FUEL HOPPER (KLIXON)
If the temperature exceeds the preset safety level, it immediately
shuts down the running of the stove, and has to be reset manually
before the stove will restart
Operation Technical service - Rights reserved MCZ S.p.A. - Reproduction prohibited

.
PELLET STOVES Chapter 4
INSTALLATION AND USE MANUAL
• BULB TEMPERATURE PROBE IN THE WATER TANK
If the temperature exceeds the preset safety level, it immediately
shuts down the running of the stove, and has to be reset manually
before the stove will restart
(see paragraph 4.20.3)
.
• WATER TEMPERATURE PROBE
If the temperature of the water approached shutdown temperature
(85°C), the probe causes the stove to go through a series of
cooling cycles or “ECO-STOP” automatic shutdown to prevent
blocking of the bulb temperature probe as described above.
• ELECTRICAL SAFETY
The stove is protected against violent surges of current by the

4.12.3. Lockout of the stove
The following things can cause the stove to lock out:
• Overheating of the structure and of the pellet hopper
• Overheating of the water in the boiler (T>85°C)
• High pressure in the outlet fumes (as read by the pressure
switch) and therefore possible obstruction of the smoke
discharge system or external back-pressure.
• Pressure in system less than or greater than the minimum or
maximum parameters of operation
The lockout is indicated by the LED (7) lighting up, accompanied by a
beep.
In this situation the shutdown cycle is automatically activated.
Once this process has started, any attempt to reset the system is
useless. The cause of the lockout is shown on the display (8).
4.12.3.1.
The stove goes into a safety ALARM state called “ALAR SIC FAIL” due

Pellet hopper safety thermostat
If the pellet hopper overheats, the stove goes into a safety ALARM
state called “ALAR SIC FAIL”.
The MCZ stoves are provided with two types of safety thermostats:
• manual reset
• self-reset
If there are two thermostats (see fig. 7 and fig. 8) on the back of the
stove, near the ON button, then the hopper thermostat is a manual
reset thermostat. If, instead, there is only the hopper safety thermostat
on the back panel, then it is self-resetting. (fig.9).

Figure 7 and
SELF-RESETTING THERMOSTAT
In this case the stove is equipped with a self-resetting sensor
which intervenes in case of high temperature.
To cancel the alarm condition, the user must shut down the stove
using the button “5” and wait for the stove body and the hopper to
cool in order to allow the self-resetting of the thermostat (about 20
minutes after the occurrence of the alarm). At this point it is
possible to light the stove again.
4.12.3.3.
• If you see the message “ALAR DEP FAIL”:
Smoke expulsion
check the ENTIRE smoke duct, including the combustion chamber,
to see that they are clean and free of obstructions. (it is
recommended that this operation be conducted by a specialist MCZ
technician).
Only after the cause of the blockage has been permanently
eliminated can a fresh attempt to relight the stove be made.

4.13. SHUTTING THE STOVE DOWN
The stove can be extinguished at any time and in any position.
NEVER SHUT THE STOVE DOWN BY CUTTING OFF THE

To extinguish the stove, press for a few seconds on the key r.
The display (8) will show the message “OFF”. At this moment the
shutdown cycle begins, in which the pellet loading screw stops, while
the smoke extractor and the hot air exchanger remain on until the
temperature of the stove has dropped.

The actual shutdown of the stove only occurs 20 - 30 minutes later,
and in any case not before the smoke temperature drops below 50 °C.
This occurs to allow the combustion fumes to be ducted into the flue
pipe by means of the extractor.
It also means that there is total recovery of the heat yielded by
combustion to the structure of the stove.
4.14. DOMESTIC WATER PRODUCTION KIT (optional) For POLAR-NOVA-ATHOS
POWER stoves only
The POLAR and NOVA stoves can also be equipped with a complete kit
for the production of domestic hot water, which is composed of:
• Plate heat exchanger
• 3-way deviator valve
• Flow switch
• Pipes and fittings for connection
The kit is pre-assembled by the manufacturer, MCZ. Its purpose is to
heat domestic water from the water line of the home.
When a hot water faucet is opened, the internal flow meter orders the
deviator valve to send the hot water in the boiler to the plate heat
exchanger. The temperature of the hot water depends a great deal on
the temperature of the heating system. As a guideline, it can be
calculated by subtracting 10°-15°C from the value shown on the control
panel of the stove (temperature of water in boiler).
If the stove is in ECO-STOP status and there is a request for domestic
hot water, 30 seconds after the request the stove automatically starts
the lighting sequence to heat the water in the boiler and then the
domestic hot water.
For long-lasting operation of the plate heat
exchanger, you need to know the water hardness of
your system in order to prevent incrustations.
If the water in your home is very hard, you should
install a water softener upstream (see chapter 3.4.3)
On a yearly basis, you should have the plate heat
exchanger serviced to remove salt and calcium
sediment, or replace the heating plates with new
ones. These spare parts are supplied by MCZ.

5. MAINTENANCE AND CLEANING
ATTENTION!
All cleaning of all parts must be carried out with the
stove completely cold and unplugged.
The stove does not need much maintenance if used
with certified quality pellets. The necessity for
maintenance increases with use and depending on
the performance requested of it.
5.1. CLEANING TO BE PERFORMED BY THE USER
5.1.1. Cleaning prior to each lighting
Clean the grate with a steel brush, removing any incrustation which could
obstruct the passage of air.
Remember that only a clean, neat grate can ensure
proper operation of your pellet stove.
A simple visual check, carried out daily, will reveal
whether the grate is in good working order.
For good cleaning of the grate, pull it completely out of its housing and
thoroughly clean the grate and holes on the bottom. If you use goodquality pellets, you will normally only need to use a paintbrush to
restore the perfect condition of the component. For tough incrustations,
use the steel tool provided with the stove and a steel brush.
Fig. 1-2
Figure 1 – Example of dirty grate
Figure 2 – Example of clean grate
page
55
5.1.2. Check every 2/3 days
Clean and empty the ash drawers, watching out for hot ash.
Only if the ash is completely cold, it is possible to use a vacuum
cleaner to remove it. Use a drum-type vacuum cleaner that is suitable
for picking up particles of a certain size.
Experience, and the quality of the pellets used, will determine the
frequency of cleaning.
It is however advisable not to let it exceed 2 or 3 days.
When the job is completed, re-close the ash drawers, making sure that
they are properly shut.
Figure 2
5.1.3. Cleaning the glass
For cleaning the ceramic glass, the use of a dry brush is recommended,
or if it is very dirty, the special spray detergent, applying a small
quantity then cleaning with a cloth.
Figure 4
ATTENTION!
Do not spray the product on the painted parts or on
the gaskets of the door (ceramic fibre cord)

PELLET STOVES Chapter 5
INSTALLATION AND USE MANUAL
5.1.4. Cleaning the heat exchanger and the pipe unit
The cleaning of the heat exchanger and the pipe unit is very important
to ensure constantly high performance and heat yield of the stove, as
ensured by MCZ.
It is therefore advisable to:
Every 30 days, with the stove cold, clean the inner walls of the
steel firebox, especially the back, with a scraper, to eliminate
encrustations caused by soot. Incrustations act as insulation. The
thicker they are, the less heat is transferred to the water and the
structure in general.
Every 7 days and with the stove cold clean the internal pipe unit.
To do this, use slight force on the handle located behind the door
above the fire door (behind the upper front ceramic). Push and pull the
handle 5-6 times so that the internal scraper removes the soot
deposited on the pipes.
Constant cleaning of the pipe unit prevents
incrustations on it, and keeps the cleaning device
from clogging and jamming.
Figure 5
page
56
Figure 5 - Cleaning of internal pipe unit with scraper
5.1.5. Cleaning of stainless steel and satin-finish surfaces
Normally these surfaces do not need to be treated, but if they do, avoid
cleaning them with abrasive materials. For surfaces in stainless and
satin brushed steel we recommend cleaning with a paper towel or a
clean dry cloth moistened with a detergent based on non-ionic
surfactants (< 5%). A spray glass cleaner may be used.
5.1.6. Cleaning of painted parts
Do not clean the painted parts with wet rags when the unit is in
operation or hot to prevent thermal shock to the paint which may cause
it to detach. Do not use abrasive or aggressive products or materials.
Clean with damp cotton or paper towels.
The silicon paints used on MCZ products possess technical
characteristics that make them resistant to very high
temperatures.
There is however a physical limit (380°-400°) beyond which
the paint begins to fade or (over 450°) to vitrify; it may then
flake and detach from the steel surface.
If this happens, it means that temperatures have been
reached that are far above those at which the unit should
operate properly.

ash and soot which has built up in the heat exchanger and in the
smoke extraction fan.
Clean the smoke discharge system, especially in the area of the tee
connectors and of any horizontal stretches of pipe.
For information refer to a chimney sweep.
Check the seal of the ceramic fibre gaskets on the door of the stove.
If necessary order new gaskets from your dealer as replacements.
At the end of the season it is necessary to clean the compartment
under the grate and the heat exchanger inside it.
This general cleaning should be carried out at the end of the season in
order to facilitate the general removal of all residues of combustion,
without waiting too long, because with time and humidity these
residues can become compacted.
Using a stiff rod or a bottle brush, scrape the inner walls of

ATTENTION: for your safety, the frequency of
cleaning the smoke discharge system must be
determined on the basis of the use you make of the
stove.

page
57
5.2.2. Shutting the stove down (end of season)
In the period when the stove is out of use it must be
disconnected from the electricity mains. For greater safety,
especially if there are children around, we recommend
removing the power cable from the rear of the stove.
(Figure 8)
Before placing the stove in storage, you should remove all pellets from
the hopper with a vacuum cleaner with a long extension. If the fuel is
left in the hopper, it may get damp, stick together, and be difficult to
light at the beginning of the next season
If the stove is removed form its place of installation it MUST be
placed in a location that is protected from atmospheric agents.
If pressing the main switch (located on the back of the stove) does not
make the control panel display light up, it could mean that the service
fuse needs replacing.
ATTENTION!
Disconnect the electrical cable.
