Preface Dear Customer, We would like to thank you for the preference which you have decided to bestow on MCZ products, and particularly for choosing one of the MCZ Pellet range. We are convinced that as you use it, you will appreciate the quality of the product, which is the fruit of careful planning and meticulous testing.
MCZ's technical assistance service. MCZ refuses to accept any responsibility in the event that the stove or any other accessory have been improperly used or modified without authorisation.
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.
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.
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.
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.
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 /h must be available) ,as laid down in the standard governing the installation (UNI - CIG 7129, 7131 and subsequent updates).
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...
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: •...

When making the hole for the passage of the smoke discharge pipe, it is necessary take into account 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...
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.
2.6 Connection to an external fluepipe in insulated or double-walled 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 12 Pa.
The operation of the pellet stove is noticeably Wind 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. Installation...
2.9 Fitting the ceramic cladding on Astra-Aurora-Antares 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.
Page 22
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.

Installation of steatite cladding Support Support Screws Screws Steatite plate Always start laying the plates starting from the lower ones. Orienting it as shown in the diagram below, insert a plate so that the 4 screws attached to it will be located in the housings of the supports fastened to the stove.
Page 24
VARIATION FOR ANTARES Remove the two screws from the pellet compartment cover, take it off and position the ceramic top (fig. 13). Refit the cover and tighten it finally (fig. 14). Fig. 13 HANDLE THE CERAMIC PANELS WITH GREAT CARE AT ALL TIMES Fig.
(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.
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").
3.4 Control panel Let us get to know the functions of the control panel. The control panel replicates perfectly the functions of the LCD remote control. In the tutorial which follows, we examine the control panel in particular, because its display only partially shows the messages addressed to the user.
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.
The remote LCD displays the language which is being selected. 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.
Page 30
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 Fig.18 • Type of installation (horizontal or vertical smoke outlet) must have been chosen.
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.

….Lighting and shutdown are 3.12 Automatic operation with the 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).
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 programming of the timer-thermostat.
3.16 Programming the timer- thermostat SELECTION OF THE CURRENT TIME AND DAY OF THE WEEK If the setting of the current time has not already been carried out , see the paragraph "Setting the current time" on page 27, and then move on to the selection of the day of the week. The LED (7) on the control panel is off.

ATTENTION ! Code UT 04 is not used for programming the timer. It is reserved for the exclusive use of the installer or qualified MCZ technician via an access key. When scrolling through the menu, always skip this code. All the programs lighting times (see UT05-UT08-UT11-UT14) must be included between a minimum of 0:00 and a maximum of 23:40.
20°C 3.18 Connecting the Fig.23 external thermostat Connect the cable coming from the Connector supplied wall-mounted thermostat to the MCZ connector port supplied with the stove. The electronic board automatically Thermostat cable detects the presence of the external thermostat, which takes precedence over the one on board the stove.
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.
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. Message on the display (8) Type of problem Solution...

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.
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 Fig.26 for maintenance increases with use and depending on the performance requested of it.
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 Fig.31 cleaning plugs from the smoke discharge pipe and clean it thoroughly.
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.
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...
