1.2 Safety instructions

Installation of the stove, making the electrical connections, checking its operation, and
maintenance are all tasks which should be carried out by qualified and authorised
personnel.

Install the stove in accordance with the regulations in force in your local area, region and
country.

For the correct use of the stove and of the electronic apparatus connected to it, and to prevent
accidents, the instructions given in this booklet must always be followed.
In addition, adjustment and regulation must be carried out by adults. Errors or incorrect settings
can give rise to hazardous conditions and/or bad running.

Before beginning any operation, the user, or whoever is preparing to operate on the stove, must
have read and understood the entire contents of this instruction booklet.

The stove must be used only for the purpose for which it is intended. Any other use must be
considered improper and therefore dangerous.
Do not use the stove for standing on or as any kind of support.
Do not put washing to dry on the stove. Any clotheshorses and suchlike must be kept a suitable

distance from the stove. – Danger of fire.

All responsibilty for improper use is taken entirely by the user and such use relieves MCZ of any
civil or criminal responsibility.

Any kind of tampering or unauthorised substitution of non-original spare parts can be hazardous
for the safety of the operator and relieves MCZ of any civil or criminal responsibility.

Most of the surfaces of the stove are extremely hot (the door, the handle, the glass, smoke
discharge pipes etc.). Avoid coming into contact with these parts, therefore, without adequate
protective clothing or suitable implements, such as gloves with thermal protection or implements
which leave the hands cool.
Carefully explain this hazard to elderly people, disabled people and particularly to all children,
keeping them away from the stove while it is running.

On no account should the stove be run with the door open or the glass broken.

Do not touch the stove with wet hands, in view of the fact that it is an electrical appliance. Always
disconnect the supply cable before doing anything to the unit.

Before carrying out any cleaning or maintenance operation, make sure in advance that the the
stove is disconnected from the mains electricity supply, by turning off the main switch located on
the back of the stove, or by unplugging the supply cable.

The stove must be connected to an electrical system which is equipped with an earth conductor,
as laid down in diectives 73/23 EEC and 93/98 EEC.
The system must be of adequate rated capacity for the stated electrical power of the stove.

Incorrect installation or faulty maintenance (not conforming to the requirements set out in this
booklet) can cause harm to people, animals or property. In such cases MCZ is absolved from any
civil or criminal responsibility.

Information

1.3 Operating instructions

In case of any problems, get in touch with your dealer, or a qualified engineer authorised by
MCZ, and if a repair is necessary, insist on the use of original spare parts.

Shut the stove down in the event of a breakdown or bad running.

Use only the fuel specified by MCZ (6 mm diameter pellets. The fuel must be supplied to the stove
only by the automatic feed system.
Pellets must not be fed manually into the burner.

Periodically check and clean the smoke outlet ducts (connection to the flue pipe).

The accumulation of unburnt pellets in the burner after repeated "ignition failures" must be re­moved before lighting.

Do not wash the inside of the stove with water.

Do not use water for washing the stove. The water could get inside the unit and damage the
electrical insulation and cause electric shocks.

The pellet stove is not a cooking appliance.

Do not expose your own body to hot air for extended periods. Do not overheat the room which
you are occupying, where the stove is installed. This could cause physical damage and also give
rise to health problems.

Do not expose plants or animals directly to a current of hot air. Both plants and animals could be
harmed by it.

Do not put anything in the hopper other than wood pellets.
Always keep the the cover of the fuel hopper closed.

Keep this instruction manual carefully because it must stay with the stove throughout its working
life. If the stove is sold or transferred to another user, always make sure that the booklet goes with
the product.
If it gets lost, ask MCZ or your authorised dealer for another copy.

Instal the stove in a location which is suitable for firefighting, and equipped with all services such
as air and electricity supply and provision for discharging combustion gases.

If the stove and the ceramic cladding are in storage, it should be in a place that is free of damp,
and they should not be exposed to extremes of temperature.
It is inadvisable to base the stove directly on the floor, and if the floor is made of flammable
material, it must be suitably insulated.

Do not light the stove with flammable materials if the ignition system breaks down.

1.4 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.

FUEL HOPPER TEMPERATURE SENSOR.

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. Take care when carrying out the
operation of resetting it, because if the stove locks out a second time, it will be necessary to call
the technical assistance centre.

ELECTRICAL SAFETY

The stove is protected against violent surges of current by the main fuse, which is located on the
control panel at the rear of the stove. Other fuses to protect the electronic boards (main board and
heat-exchanger board) are to be found on the boards themselves.

FAILURE OF THE SMOKE EXTRACTION FAN
If the fan stops, the electronic board shuts off the supply of pellets in good time, and an alarm
message is displayed.

BREAKDOWN OF THE REDUCTION MOTOR
If the reduction motor stops, the stove continues to function until it has cooled down to the
minimum level.

TEMPORARY POWER OUTAGE
After a brief interruption of the electrical power, the stove relights automatically.

FAILURE TO LIGHT
If during the lighting stagea flame does not start, the stove automatically makes a further attempt
to light.

TAMPERING WITH THE SAFETY DEVICES IS PROHIBITED

It is only after eliminating the cause which gave rise to the intervention of the safety system,
that it is possible to relight the stove and thus reset the automatic operation of the sensor.

Attention !

If the stove is not used as described in this instructi on booklet, the ma nufacturer refu ses to
accept any responsibility for damage to pers ons and prop erty that may arise. The ma nufacturer
furthermore refuses to accept responsibility for damage to persons and property arising from
the failure to observe all the rules contained in the manual and in particul ar:

• Failure when carrying out works of maintenance, cleaning and repair to adopt all
necessary measures and precautions.

• Tampering with the safety devices.

• Removing the safety devices.

• Failure to connect the stove to an efficient system for the discharge of smoke.

• Failure to check in advance that the room where the stove is to be installed is

adequately ventilated.

Information

1.5 Operating principle

The pellets are picked up from the hopper on board the stove and transported by a feed screw.
They are then introduced into the combustion chamber and fall directly into the stainless steel
grate.
The quantity of pellets introduced into the grate and the corresponding air of combustion are
predetermined, programmed and controlled by an electronic board.
In the lighting phase, the electronic board activates the smoke extraction fan and the ceramic
sparkplug, which heats up and causes the fuel to ignite at a temperature of about 200°C. After
about 20 minutes, the lighting phase is complete, and the control unit puts the stove into operating
mode.
In this phase, on the basis of the instructions which we provide via the infrared remote (5 power
levels), the electronic board regulates the exact relationship between quantity of fuel, combustion
air and convection air, and provides continuous monitoring of all the components connected to it,
indicating if necessary the presence of any operating problems and stopping the process.

1.6 The 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 kg/m
content which varies from 5% tp 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 diameter, in terms of its specific gravity
and particle size.

By using the special measuring container 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 good­quality 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 damp, and protected from dirt. Pellets are supplied in 15 kg
bags, so they are very convenient to store.
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:
Calorific power: 5.3 kW/kg
Density: 700 kg/m

3

Moisture content: 8% max by weight
Ash percentage: 1% max by weight
Diameter: 6-6.5 mm
Length: 30 mm max
Content: 100% untreated wood, with no added bonding substances (bark percentage 5% max)
Packaging: in bags made from ecologically compatible or biodegradable material

MCZ emphatically 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.

Vega, Astra,Aurora and Antares stoves run exclusively on pellets with a diameter of 6 mm
and a length rage from 5 mm to a maximum 30 mm.

2.1 Working environment

For proper functioning and a good temperature distribution, the stove should be positioned in a location where
it is able to take in the air necessary for combustion of the pellets (about 40 m
down in the standard governing the installation (UNI - CIG 7129, 7131 and subsequent updates).
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

/h must be available) ,as laid

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 may be drawn from rooms next door to the room which needs ventilation, provided that
these rooms have an air intake from outdoors 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. The provisions of
standards UNI 7129 and 7131 and subsequent amendments absolutely must be respected.

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 take 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 hangings, sofas and other
furniture, their distance from the stove should be considerably increased.

If the floor is made of wood, fit the floor protection plate.

2.2 Preparation

The Vega stove is delivered in a single package.

Astra, Aurora, and Antares stoves are delivered in two
packages:
The first contains the stove unit Fig.1
The second contains the ceramic cladding.Fig.2

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.

Fig.1

2.3 Installation and fitting

Installation and assembly of the stove must be carried out by a qualified engineer.

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

• provided with a suitable electricity supply: 230-240 V 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 conduit
conforming to the 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 conduit 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.

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, make a hole right through an external wall in proximity to the stove, with a
minimum free 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:

• 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

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.

15

Grille for external air intake

Installation

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 (thickness1.3—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 heat-sensitive wall
As an alternative we recommend the use
of insulated pipe, which can also be used
on the outside to avoid condensation.

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

Installation

Lining up the
smoke outlet and
the connecting
pipe

Fig.3 Fig.4

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 (Fig. 3) to get the stove correctly levelled so that the smoke outlet is lined

up with the connecting pipe. 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. (Fig. 4)

Some typical examples of correct installation are illustrated below.

2.5 Connection to the flue

The flue of must have internal dimensions not
larger than 20x20 cm or diameter 20 cm. In the
case of a flue with larger dimensions or in poor
condition (e.g. cracks, poor insulation etc.), it is
advisable to line the flue with a stainless steel
pipe of suitable diameter for its entire length,
right up to the top (Fig 5).

Check with suitable instruments that there is a
minimum draught of 12 Pa.
At the bottom of the flue pipe, provide an
inspection cap to allow periodic checking and

Least favourable points

Wind

Among all the meteorogical and geographical factors
which influence the operation of a flue (rain, fog, snow,
altitude above sea level, amount of sunlight, exposure to

different compass directions), the wind is certainly the one

which has most effect. Besides the thermal depression
brought about by the difference in temperature between
the inside and outside of the flue, there exists another kind
of depression (and overpressure): the dynamic pressure
induced by the wind. A rising wind always has the effect of
increasing the depression and therefore the draught. A
horizontal wind increases the depression if the cowl is
correctly installed. A descending wind always has the
effect of reducing the depression and sometimes of
reversing it.

Most favourable position

Trees/hills/other buildings

Descending wind

High-pressure zone Low-pressure zone

Besides the direction and force of the wind, the position of the flue and the cowl with respect to
the roof of the building and the surrounding landscape is important. The wind also influences the
operation of the chimney indirectly by creating high-pressure and low-pressure zones, not only
outside the building but inside as well. In rooms directly exposed to the wind (2), an indoor high­pressure 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)

ORIENTATION OF THE CERAMICS

After positioning the stove in the chosen location, level up the stove body by means of the
adjustable feet fitted to the base. Carry on with fitting the ceramic cladding only after making the
connection to the flue pipe or the vertical smoke duct as described above.

The ANTARES stove has panels of identical design which can be fitted on the right-hand or the left­hand side, and either way up.
The AURORA stove, however, has panels of identical design which must go in fixed positions (fig. 8).
The ASTRA stove has panels (with different designs) with different layouts for the two sides (fig. 9).

FITTING THE CERAMIC CLADDING

After reading the previous paragraph entitled "Orientation of the ceramics", scrupulously follow the
stages described below.

Take a panel from the pack (following the fitting sequence recommended on the previous page)
and move it to the side of the stove where it is to be fitted (fig. 10 ). Locate the panel so that the
fixed retaining hooks (A) at the front of the stove engage in the rebate in the panel as indicated in
fig. 11.
At the rear of the panel, engage the moveable hooks (B) in the appropriate rebate in the panel.
Using a screwdriver, tighten the screws in the hooks, but not all the way, so as to lock the panel
(fig 12). Check that the panel is secure and aligned with the other panels, bearing in mind that
THE PANELS MUST NEVER BE RIGIDLY FIXED.
Fit the top by resting it on the 4 rubbers (K) fitted to the frame.

Checks to make before lighting the stove

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 from the pellet hopper the cardboard box
containing the general instructions, and any
materials which could burn (various instructions
and stickers).

Check that the central ash-drawer (A) on the Astra-

Vega-Aurora, or the two ash-drawers on the
Antares, is/are correctly positioned and properly
closed.

Check that the grate (B) and its flame shield are

correctly positioned.

Check that the perforated upper deflector (C),

inside the combustion chamber, is positioned
correctly (fig. 16).
After long periods of disuse, remove from the

hopper (using a vacuum cleaner with an
extension) any remains of pellets which

have lain there for some time, since they may
have absorbed moisture, which changes their
original characteristics and makes them

unsuitable for burning.

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 alternating message OFF /
CURRENT TIME.

3.2 Loading the pellets

The pellets are loaded through the top of the
stove, by opening the cover. Pour the pellets
into the hopper, up to a maximum of 34 kg
(more than two bags). ( 2 bags for the
Antares and about 23 kg, which is well over 1
bag, for the Vega-Astra-Aurora). See fig. 17.

Do not remove the protective grille from
inside the hopper. When loading pellets,
avoid the bag coming into contact with
hot surfaces.

Use of the stove

3.3 Instructions and advice on first lighting

Avoid touching the stove during the initial lighting, since the paint is hardening at this stage.
Touching the paint could make the steel surface show through.
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 during the initial lighting, as the stove will give off
fumes and smell of paint.
Do not remain close to the stove, and, once again, ventilate the room well. The fumes and the
smell of paint will disappear after about an hour of operation, but remember that they are not
harmful to health.

The stove will be subject to expansion and contraction during the stages of lighting and cooling
down, and may therefore make slight creaking noises. This phenomenon is absolutely normal, the
structure being made of sheet steel, and must not be considered a fault.

It is extremely important to be sure not to take the stove to full heat straight away, but to bring it
gradually up to temperature as if it were a car.
If in 'Manual' mode, use the lower heating levels (1st, 2nd, 3rd). On subsequent lightings, you will
be able to enjoy the full heating power available (including 4th and 5th levels), but remember not
to keep the stove running on full power for more than 60-90 minutes. In this way you will avoid
damage to the ceramic panels, the welds and the steel structure.

The first time the stove is lit, leave it in 'Manual' mode and
use only moderate power settings, such as 'Manual 1',
'Manual 2' and 'Manual 3'.

Do not demand full heating performance straight away!

Try to become familiar with the commands transmitted by the control panel and the LCD remote
control. Try to memorise visually the messages which the stove is sending you via its remote
displays (on the control panel and the remote control).

'Manual 1', 'Manual 2' and 'Manual 3' are captions which appear only on the LCD remote control.

3.5 Managing the stove with the LCD

To use the remote control for purposes of programming or operation, take up a position within
the area indicated in the diagram below and point the remote at the stove. If there is an

obstacle which prevents the signal from the remote reaching the stove (a piece of furniture, for
example), the unit will not work.
In some situations the maximum range of communication is 6 metres.

reception, always position
yourself centrally, pointing
the remote control
towards the stove.

Points to remember about the remote control

• Never expose the remote control to direct sunlight.

• Dust deposited on the transmitter or receiver could reduce its sensitivity. Dust

should be removed with a damp cloth.

• The communication signal may not work if there is a fluorescent light in the room with

electronic starting (e.g. inverter-type lamps). In this event, consult your dealer.

• If you find that the remote control activates another appliance, move the other appliance

somewhere else, or consult your dealer.

• Do not drop the remote control, or get it wet.

• The remote must not be left near sources of heat, and it must be kept out of the reach of

children.

The remote control is set up with the energy-saving option active, which means that if it is
not operated for an hour, the display automatically switches off. Press any key to restart it.

Warnings about the battery

• If you are expecting the remote not to be used for a long time, remove the battery.

• When the display screen (8) of the remote control becomes hard to read, and reception

of the signals becomes difficult, replace the battery with a new one.

T h e b a t t e r y s u p p l i ed with the remote is intended only for the initial use of the stove.

• The usable life of the battery could be less than expected, depending on the date of manufacture

of the stove.

The expected operating life of the 9v battery fitted to the remote control is about 2000 hours (90 days).

3.6 Settings to carry out before
first lighting

Set the main switch on the rear of the stove to position (1).
The display (8) on the control panel will show the alternating message OFF / CURRENT TIME.
If the time shown is not correct, it can be reset by the procedure described below.
It is worth remembering that the internal clock is only used when programming the weekly

schedule using the TIMER function (see the relevant chapter).An incorrectly-set clock therefore

does not in any way impair the operation of the stove.

3.7 SETTING THE CURRENT TIME

Press keys 2-3-3 in sequence.
Display will show UT02 and the hour. Use key 1 or 2 to

decrease/increase the hour.
To confirm the hour selected and move on to selection of the

3.9 SELECTING THE RECIPE

This is an evaluation criterion exclusive to MCZ which allows the user to identify
the type of pellet which is available and as a result to select the optimum settings
for the stove. This avoids excessive fuel consumption, ensures that the expected
volume of heat is available and that the appliance is protected from damage.

SELECTION OF THE RECIPE IS AN OPERATION WHICH SHOULD BE CARRIED OUT ON
FIRST INSTALLATION AND WHENEVER THE TYPE OF PELLET CHANGES (for example if

you change supplier or become aware visually of differences in the colour or particle size)

28

Use of the stove

Procedure for recipe selection

Requirements:

• Scales (measuring up to 4 kg) with graduations down to 10 g

• MCZ pellet measuring container supplied with stove

• A batten

• Pellets

• Type of installation (horizontal or vertical smoke outlet) must

have been chosen.

Fill the measure generously with pellets without compacting it (i.e.

without banging the measure on the table or pressing the pellets down
with the hands) – fig. 18.
Rest the batten (or ruler, blade or pencil) on the top edge of the
container and level the material by scraping off the excess – figs. 19
and 20.
Weigh the total (container + pellets) and note the weight.
Take the measure, empty it, and look at the table designed for the
selection of the recipe – fig. 21.
In the left-hand column, marked 'Weight', identify which row contains
the weight which was noted earlier.
Following the row across to the right, you will see two numbers which,
depending on the type of installation of the stove (with smoke outlet
predominantly vertical or horizontal) will allow you to select the
optimum recipe for the type of pellet being used.

Example:

Let us suppose that we decide to

Fig.21

install the stove in the

configuration with a vertical flue
pipe and that the weight of the
measure including pellets is 680

grams.

First of all, let's identify the model
of stove that we are dealing with
(e.g. ASTRA), then let's look at
the corresponding table located
on the face of the measure and
we observe that in the column

"Weighted" the 680 g are
included in the line titled “from
660 to 700”.

Staying on this line, on the right

we identify the message “G2”

which corresponds to the column

which has a s a symbol a stove
with a vertical smoke flue.

The recipe with which the stove

will be programmed is G2.

3.10 HOW TO DISPLAY AND PROGRAM THE SELECTED RECIPE

Press keys 3 and 4 simultaneously.

The display shows the recipe currently selected.
Alternatively, if the display shows the symbol ' — ‘, it indicates that no recipe is currently selected.

To exit from the menu without making changes, press key 3 or key 4 or wait 120 seconds without

pressing a key.

The procedure for selecting the recipe is active only
when the stove is not lit.

To set or modify a recipe, the procedure is as follows:

Press keys 3 and 4 simultaneously.
Press key 1 or key 2 to search for the parameter relating to the required recipe according to the

following table:

Parameter Display Model of stove

G0 RECIPE VEGA-ASTRA-AURORA
G1 RECIPE VEGA-ASTRA-AURORA
G2 RECIPE VEGA-ASTRA-AURORA
G3 RECIPE VEGA-ASTRA-AURORA

G8 RECIPE ANTARES
G9 RECIPE ANTARES
H0 RECIPE ANTARES
H1 RECIPE ANTARES
H2 RECIPE ANTARES
H3 RECIPE ANTARES
H4 RECIPE ANTARES
H5 RECIPE ANTARES

Example of message displayed on the remote control:

G1 / SET / RECIPE 2 indicates that we have a stove model VEGA, ASTRA or AURORA and have

chosen a setting for a 'lightweight' pellet with smoke outlet predominantly vertical.

H4 / SET / RECIPE 7 indicates that we have an ANTARES stove and have chosen a setting for a
'heavy' pellet with smoke outlet predominantly horizontal.

N.B.
On some models, the
message “Recipe” may
appear as “Ric”

To make the change active, hold key 5 down for several seconds.

All VEGA-ASTRA-AURORA stoves are default set to recipe G1
The ANTARES stove is set to recipe G9.

Use of the stove

3.11 Lighting the stove using the

….Lighting and shutdown are
performed by the user

control panel or the remote

To start the stove, press Key 5 for several seconds.

After a few moments, the stove goes into a state of adjustment and then, when the message

“Charge pellet” appears, the stage of loading pellets and lighting starts. This stage will last for 15

minutes on average.

If during this phase the flame does not appear and hence the ignition procedure is not completed,
the display (8) shows the message "No ignition alarm". In this case shut down the stove by
pressing the push button (5). The display (8) will show the message “Off / current time”.
Remove any pellets from the burner and repeat ignition by pressing push button (5) for a few
seconds.

If the lighting stage is carried out correctly, after about 10 minutes the message "Fire regulate"

appears on the display (8), which is characteristic of the phase in which combustion is being
established and regularised.

At the end of this phase, the stove goes into normal working mode and shows on the
display (8) the ambient temperature and the reference power level "On 3", while the LED
(10) indicates the operating mode MANUAL.

This base criterion (medium power level, On 3 and manual operation), has been selected to give
the user the opportunity to optimise heating and also check fuel consumption. Remem ber that for
correct use of the stove in manual mode, the programmer or timer must be out of circuit (LED 7
must be off).

At this point the user, if so desired, can select a different power program among the five stored in
memory, by means of Keys 3 and 4.
Pressing Key 3 increases the heating power and consequently the fuel consumption.
Pressing Key 4 has the opposite effect.
Every change in the power level is accompanied by an audible 'beep'.

When the power setting is altered, the hot air ventilation automatically alters as well.

It is advisable to inspect the contents of the hopper from time to time, to avoid the fire going out
for lack of fuel.

ATTENTION !
If, while the stove is running, conditions occur which modify the the normal state of
operation, the general alarm LED (6) lights up, accompanied by an audible 'beep' (see the

paragraph on "Lockout of the stove"), and the stove reacts by starting the process

of complete shutdown.

In the event of an electrical power-cut, the stove goes through a cooling-do wn

stage and later automatically relights itself.

Note:
The phrase 'subsequent lightings' is intended to refer to lightings in which the feed screw is full of
pellets. In these cases, the burner must be cleaned of the residues of previous combustion every
time the stove is relit.

Use of the stove

31

3.12 Automatic operation with the

….Lighting and shutdown are
performed by the user

digital room thermostat

It is possible to regulate the power of the stove automatically, using the digital thermostat which is already
set up in the electronic control unit.
In order to regulate the stove when it is operating in this mode, it is necessary to set the thermostat to the
desired temperature, which must be within the range 10°C to 40°C (for example, 20°C).The thermostat
manages the operation of the stove, switching in smart fashion between the available power levels (1-5).
Example:
If the ambient temperature reported by the local sensor positioned on the stove is 15°C and the
temperature set on the thermostat is 20°C, the stove moves (by predetermined stages) up to 5th power
level, and on achieving its target of 20°C, it switches back down through 4th, 3rd and 2nd power levels to
finish at 1st power level.

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 20°C in the room, it may be necessary to set the thermostat on
the stove to 25°C).

In this mode, lighting and shutdown are performed by the user, by pressing Key 5 for several
seconds.
On lighting, however, the stove reverts to the MANUAL mode "Manual 3". If you want the
operation of the stove to be controlled by the digital thermostat, you need to reset the mode to
AUTOMATIC.

The only mode in which the stove will light and shut down independently at preset times is "Automatic
operation with the timer-thermostat".

timer-thermostat

The timer-thermostat function is used to program the automatic lighting and shutdown of the stove
and the setting of the desired ambient temperature over the course of the week.

• First, set the temperature of the digital thermometer (see "Moving from manual operation to

automatic").

• Next, decide on a series of heating programs on the basis of your own needs.
A heating program consists essentially of three parameters:

Lighting time
Shutdown time
Days to which the program applies / does not apply

On MCZ stoves, up to four daily programs can be set up.

Use the example given below to help you construct your own table, then move on to the

Press Key 3 to confirm and move on.
Press Key 3 again until the display (8) shows the code UT 05 , which signifies lighting time for the
1st program. Alternating with UT 05 the message "6.00" appears: use Keys 1 and 2 to set the

desired time (with increments of 10 minutes). When lighting time (for program 1) has been set,

press Key 3, and on the display (8), alternating with the code UT 06, will appear the shutdown
time. This too can be adjusted by means of Keys 1 and 2 (with increments of 10 minutes).
When this has been done, press Key 3 once again, and at this point we have to decide which

days of the week Program 1 should apply to.

On the display (8) appears the message "Off 1", which indicates that on Monday the timer is off,
and therefore the stove will not light and shut down automatically. If at this point we press Key 1,
the message will change from "Off 1" to "On 1", and this signifies that programming on Monday

is activated. If you want to make Program 1 active for other days as well, select the days

concerned by means of Key 2, and use Key 1 to activate "On" or deactivate "Off" in the

programming.

After doing this, move on by pressing Key 3 and you come (with the code UT 08) to the lighting
time for Program 2. To carry out all the programming, all that is necessary is to repeat the steps

just described, making use of help from the TIMER SUMMARY TABLE.

To review the settings just made, press Key 2, and the days and the processes assigned to them

will be displayed.

3.17 Operation of the stove using the
external thermostat

The stove can also be controlled as regards temperature by an external room thermostat. If this is
fitted in a mean position with respect to the area in which the stove is installed, it ensures a closer
correlation between the heating temperature requested from the stove and the temperature it
effectively delivers. In other words, it will not be necessary to take an average between the
temperature read by the ambient sensor mounted on the stove (e.g. 15°C) and the temperature you
want to reach (e.g. 20°C) for inputting into the digital internal thermostat. (See the paragraph
"Automatic operation with the digital room thermostat").

Without the external room thermostat Fig.22

1-Temperature read by the ambient sensor –e.g.15°C

3.18 Connecting the
external thermostat

Connect the cable coming from the
wall-mounted thermostat to the MCZ
connector port supplied with the
stove.
The electronic board automatically
detects the presence of the external
thermostat, which takes precedence
over the one on board the stove. In
the case of programmed operation,
the phases of "lighting" and
"shutdown" will be controlled by the
internal timer fitted on board the
stove.

Thermostat cable

In this mode of operation,
the stove's digital internal
thermostat needs to be set
to the minimum

temperature possible –e.g.10°C.

See p. 31.

Use of the stove

3.19 Watching the flame

In order to achieve good running for the stove, you need to know how to "read" the flame. The
characteristics to which the user needs to pay attention are essentially:

• The shape

• The colour

• The character

The shape
In proper combustion, the flame should have a tapering form, with a "lively" character. It should be

as wide as the grate from which it radiates, with the point tending to the vertical, or flattened towards
the back surface in Alutec70 of the combustion chamber. You should get the sensation that the flame
is "drawn" upwards, so that it does not spill forwards towards the glass of the door –Fig.…

Conversely, a flame which swells outwards at the base beyond the dimensions of the grate, whith a

"thin"character, with a point that appears "aimless", which beats against the glass, 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 running problems. Call on the services of specialised personnel or
the expertise of MCZ technical staff.

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.

The character is connected with the shape of the flame.

Proper combustion

Shape: tapering, vertical, compact
Character: lively
Colour: yellow - light yellow - white

Use of the stove

Poor combustion

Shape: swollen, overflowing, not compact
Character: tenuous, feeble
Colour: orange - yellow

37

3.20 Alarm signals

In the event that a running problem occurs, as the stove is equipped with a computerised
monitoring system, it informs the user via the display of the nature of the fault and where it has
occurred.
The following table summarises the principal alarms which may be indicated.

Use of the stove

3.21 Other messages

“COOL FIRE”

Generally appears at the cooling stage following a shutdown caused by an electrical power-cut.

“MODULATION”

Appears when the conditions set on the local / remote room thermostat are satisfied. In these
conditions, the stove modulates its power level from maximum to minimum. If the message is

accompanied by "HOT SMOKE", it means that the temperature of the smoke is above the safety

threshold preset as default. The stove is trying to cool down by changing to minimum power level
and increasing the speed of the heat-exchanger to maximum. Once this objective is reached, it
returns to the "ON" phase.

“STOP FIRE”

This is a phase which is repeated periodically every hour and has the function of cleaning the
grate of unburnt residues of pellets, which, when the stove is in operation, are deposited on the
bottom of the grate near the passages for combustion air. For 30 seconds the smoke-extracting
fan goes at maximum revs, thus purging the grate and ensuring free passage for the combustion
air through its dedicated airways.

3.22 Lockout of the stove

The following things can cause the stove to lock out:

• Overheating of the stove body

• 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.
The lockout is indicated by the LED (6) lighting up,
accompanied by an audible "beep".
In this situation the shutdown cycle is automatically activated.
Once this process has started, any operation which is an
attempt to reset the system is useless.
The cause of the lockout is shown on the display (8).
When the stove is cold:

If the message "Alarm hot pel" appears, it will be necessary

to unscrew the cover of the thermostatic sensor fitted to the
back of the stove and press the red button to reset it. Refit
the protective cover. Fig.24-25

If the message "Alarm pressure" appears, it will be

necessary to check that the WHOLE flue system, including
the combustion chamber, is clean and free of all obstruction
(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.

Fig.24

Fig.25

Use of the stove

39

3.23 Shutting the stove down

The stove can be shut down at any time and in whatever state it is in.
Never shut the stove down by cutting off the electricity supply:
Always leave it to complete the shutdown cycle, otherwise damage could be
caused to the structure, and also problems with lighting in the future.

To shut the stove down, press Key (5) on the control panel or the remote control, for
several seconds.

On the display (8) the message "Off" will appear. 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 fallen sufficiently.
The real stopping of the stove only occurs 20 - 30 minutes later, and at all events not before the
smoke temperature falls 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.

3.24 Locking the keyboard on the control panel and
the LCD remote

This is a safety feature which MCZ provides, so that once the optimum settings for operation have
been found, no-one (children particularly) can accidentally or deliberately change the parameters
which have been set.

It is activated/deactivated by the following sequence of keystrokes. Remember that only key (5)

must be pressed for several seconds:

1-4-5 (Not more than one second must be taken in moving from 1 to 4)
The message "Keyboard locked" will appear

To unlock it, repeat the process just described.
In the case of an electrical power-cut, the keyboard lock is not memorised, and when the power
comes back, the locking procedure will have to be repeated (if it is still considered appropriate).
The keyboard lock can be activated or deactivated at any time, and in whatever operating position

the stove is in.

Use of the stove

4.1 Periodical cleaning and checks

ATTENTION !
All operations of cleaning all parts
must be carried out with the stove
completely cold and with the

electric plug pulled out.

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.

Fig.26

Cleaning to be dealt with by
user

Before EVERY LIGHTING, use the special tool

to clean the grate of ash and any incrustation
which could obstruct the passage of air (Fig.

26).
Clean the perforated upper inner deflector in
the same way (Fig. 27).

CHECK EVERY 2/3 DAYS

Clean and empty the ash drawers, watching out
for hot ash (Fig.28-29).

If the ash is completely cold, it is possible to

use a vacuum-cleaner to remove it, in which case
a machine of the wet-and-dry canister type
should be used, suitable for picking up particles
of a fair 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.

4.2 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. Fig.30

Attention
Be careful not to spray the product
on the painted parts.

Cleaning to be dealt with by
specialized technicia

4.3 Monthly check

Still with the stove cold, open the door below the grate
(Fig. 31) and with a vacuum cleaner remove the ash and
soot accumulated in the heat exchanger. Remove the
cleaning plugs from the smoke discharge pipe and clean it

thoroughly.

4.4 Check to be carried out every
2 or 3 months or as required

Remove the two central side panels in ceramic, RH and
LH, open the two corresponding caps and also the door
below the grate, and with a small brush and a vacuum
cleaner, clean all the accumulated ash and soot. Fig.32
These simple but useful operations ensure increased
longevity for the appliance and also help to increase the
efficiency of combustion while also drastically reducing
pollution.

These maintenance operations must be carried out by
a specialised technician.

Fig.31

Fig.32

4.5 Non-scheduled maintenance
and general cleaning

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. Fig.33-34

ATTENTION: for your safety, the frequency of
cleaning the smoke discharge system must be
determined on the basis of the use to which
the stove is put.

Check the seal of the gaskets in ceramic fibre which are
fitted to the door of the stove and on the BURNER ASH
COLLECTING DRAWER.
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.

Maintenance

4.6 Shutting the stove down (end of
season)

At the end of season, before placing the stove in
storage, we recommend completely removing
pellets from the hopper with the use of a vacuum
cleaner with an extension.

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 supply
cable from the rear of the stove.

If the stove is removed form its place of

installation (during the warm seasons) it MUST

be placed in a location that is protected from
atmospheric agents.

When the batteries supplied with the remote control

Fig.35

4.7 Replacing the batteries
in the remote control

are discharged, they must be replaced with those of
the same format (n.2 AA 1.5V). Generally this
operation must be carried out at the start of every
season (and at all events after 2000 hours). Remove
the cover from the remote, take out the batteries and
insert the new ones, taking care not to twist the wires
of the battery connector (Fig. 36). Dispose of the
dead batteries in accordance with current local
regulations.
If pressing the the main switch (located on the

4.8 Replacing the fuse in the
main switch

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 electricity supply
cable.

On the rear of the stove there is a fuse holding
compartment which is located underneath the
supply socket. With a screwdriver open the cover
of the fuse holding compartment, and replace
the fuse if necessary (3.15 AT delayed type).
Fig.37
Push the electric plug back in, and press the
main switch.
If the problem persists, or if the fuse blows again,
call our technical assistance centre.

4.9 Checking the internal components

Checking the internal electromechanical components must only be done by qualified
personnel with technical knowledge relating to combustion and electricity. If necessary ,
refer to authorised MCZ technical assistance centres. We recommend that an annual

maintenance service is carried out, preferably under a programmed service contract. The
essential part of this service is a visual and functional check on the following components:
Reduction motor
Smoke expulsion fan
Smoke sensor
Heat-exchanger fan
Ignition sparkplug
Resettable pellet thermostat
Room temperature sensor
Pressure switch
Main board
Silenced board for heat-exchanger
Fuses protecting panel - main board - silenced board

5.2 Maintenance and/or replacement
of the electronic boards

ATTENTION !

This operation must be carried out exclusively by
a specialised technician, with the stove
completely cold and the electric plug pulled out.

If it is thought that one or both of the electronic boards
could be defective or require maintenance, proceed
with their removal.

Remove the rear protective panel. Fig. 38

The main board A is identifiable because it is

enclosed in a PVC container, whereas the board

which controls the exchanger B is protected on one

side by the corner support for the boards and on the
other by the reduction motor.
For safety reasons the steps which are necessary to
get to these boards are omitted, leaving it to the
knowledge of the installer to decide what needs to be
done and what is the most suitable way to go about it.

Send the defective or damaged board to MCZ Spa.

10-Summary of main instructions and operating rules

Fuel type: 6 mm diameter pellets, tested according to ONORM M 7135.
The stove must be installed by an authorised MCZ technician, following the instructions contained
in this booklet.
Consult local regulations and respect safety distances from flammable materials.

SELECTION OF RECIPE

This is an operation which must be performed on first installation and each time the type of pellet
is changed. If possible, purchase only one type of pellet from your dealer of choice.
Determine the recipe according to the procedures set out in para. 3.9 on page 27, and set the
stove as set out in para. 3.10 on page 29.

LIGHTING

To light the stove, press Key (5) for several seconds.
After approx. ten minutes the message appears on display (8) "Fire regulate", which indicates the

phase of stabilisation and regularisation of combustion.

When this phase is over, the stove moves to working mode, showing on display (8) the
ambient temperature and the reference power level "3", while LED (10) indicates operating
mode "MANUAL".
Use Keys (3) and (4) to regulate the thermal power of the stove and the hot air ventilation.

SHUTDOWN

To shut down the stove, press Key (5) for several seconds.
On display (8) the message "Off" will appear and from that moment the stove automatically begins

the shutdown cycle.

WARNINGS

• When the stove is running, keep children away from it and do not touch the appliance

without suitable protection (e.g. the gloves supplied), as contact with the skin could cause
burns.

• Keep furniture and flammable materials at the proper distance.

• DO NOT OVERHEAT THE STOVE, OR RATHER AVOID KEEPING IT AT MAXIMUM

POWER FOR MORE THAN 60-90 MINUTES.

• Check and clean frequently the internal components, the connecting pipe and the flue (see

chapter 4.1 of this booklet). In certain conditions of use, an accumulation of ash can occur.

• Do not put anything in the hopper but wood pellets.

• Do not use your bare hands for removing pellets from the hopper.

• Do not touch the stove with wet hands, as it is in fact an electrical appliance. Always unplug

the electrical supply cable before doing any work on the stove.

• Do not open the firedoor when the stove is running.
