operation.

It is prohibited to insert other types of fuels in the tank other than wood pellets.

Some tips to avoid corrosion phenomena:

- carry out routine cleaning operations to avoid the build-up of ash deposits;

- feed the appliance only with fuel having the characteristics described in the section "Fuel characteristics";

- Do not use solvents, acids, aggressive detergents or products to directly clean the glass or other components of the product;

- avoid leaving the product in unfavourable ambient conditions (humidity, airborne salinity, storms, etc.);

- if the appliance is not used for long periods (e.g. during the summer), disconnect the combustion air inlet pipe and place dessicant bags in the combustion chamber to absorb the humidity in the air, making sure to remove them when the product is re-ignited.

3 FUEL CHARACTERISTICS

3.1 Fuel characteristics

The pellet (Fig. 2) is a compound made from various types of wood pressed together with mechanical procedures in compliance with environment protection regulations, and it is the only fuel required for this type of appliance.

Pile of cylindrical brown granules or pellets, labeled as Fig. 2 (no text on the particles themselves)

The efficiency and thermal potential of the appliance may vary according to the type and quality of the pellets used.

We recommend the use of class A1 pellets (ISO 17225-2 standard, ENplus A1, DIN Plus or NC 444 category "High Performance NF Pellets Biofuel Quality").

Use pellets with standard length between 3 and 40 mm.

Using poor quality pellets or pellets that do not comply with the manufacturer's indications may compromise the normal operation of the appliance, cause damage (including aesthetic damage) to the product and result in the warranty being voided.

The appliance is equipped with a pellet storage tank having the capacity indicated in table "4.3 Technical features" on page 49.

The loading compartment is positioned at the top, it must always be open for loading of the pellets and must remain closed while the appliance is operating.

It is prohibited to use the appliance as an incinerator to burn rubbish.

3.2 Pellet storage

Pellets must be kept in a dry place, not too cold and the bags must be kept sealed.

It is advisable to keep a number of bags of pellets in the room where the appliance is being used or in an adjacent room provided it is at the correct temperature and humidity and at a safe distance (at least one meter) away from heat sources.

Wet and/or cold pellets (5 °C) reduce the thermal potential of the fuel resulting in the need for more cleaning maintenance of the burn pot (unburned material) and of the fire box.

Pay particular attention to the storage and handling of pellet bags. Their crushing and the formation of sawdust must be avoided.

If sawdust is placed in the appliance tank it could cause the pellet loading system to block.

6 PREPARING THE PLACE OF INSTALLATION

6.1 General considerations

The following paragraphs contain some guidelines to be followed to obtain the maximum efficiency of the product purchased and to ensure safe operation. The following indications are however subject to compliance with any possible national, regional and municipal laws and regulations in force in the country where the appliance is installed.

In Italy, installation must be performed by qualified personnel in compliance with the EN 10683 standard.

6.2 Safety Precautions

The operations for assembly and disassembly of the appliance are reserved for specialist technicians only.

It is recommended to be sure of their qualifications and their actual capacity.

For Italy, these technicians must be in possession of the letter "C" qualification issued by the chamber of commerce based on the Ministerial Decree. 37/08.

6.3 Place of installation

For the minimum distances that must be respected when positioning the appliance with respect to flammable materials and objects, refer to the instructions in Fig. 12.

Z Y2 X2 X1 Y1 Fig. 12

Model X1	X2 Y1	Y2 Z
MELITA	800	150 200	200	600 mm
NINA	800	150	200	600 mm

Floors made of flammable material such as wood, parquet, linoleum, laminate or floors covered with carpets must be protected by a fireproof base under the appliance that also protects the front during cleaning from any falling burning residues.

The manufacturer declines all responsibility for any variations in the characteristics of the material constituting the floor under the protection.

Set up an accessible technical space for any maintenance work.

Remember to respect the minimum distance from flammable materials (X), shown on the identification plate of the pipes used to make the chimney (Fig. 13).

Pi = Flammable wall

Pp = Floor protection

Pi X Pi X1 Pp Fig. 13

Set up the electricity supply line to arrive near the appliance for the connection of the power cable.

6.4 Combustion air

The appliance, during its operation, requires combustion air.

The inflow of combustion air can be obtained in the following ways:

• it can come directly from outside with direct connection to the combustion chamber (Fig. 14).
• it can come from the installation room or suitable adjacent rooms (Fig. 15)

Extraction of combustion air from outside

Connect the combustion air inlet of the appliance to the air intake using a special pipe (Fig. 14).

Fig. 14

Extraction of combustion air in the room

Create the air intake on the wall (Fig. 15 - PA = Air Intake), and leave the appliance to withdraw the room air, making sure to connect the provided pipe on the air inlet pipe, to prevent any resonance effects.

PA Fig. 15

If the rear wall of the appliance is an external wall, make a hole for the intake of combustion air at a height of about 20-30 cm from the ground, respecting the dimension indications given on the technical data sheet at "4.3 Technical features" on page 49.

A non-closable permanent aeration grid must be placed externally; in areas that are particularly windy and exposed to weathering, provide rain and wind protection.

Ensure that the air intake is positioned so that it won't be accidentally obstructed.

If it is impossible to create an external air intake in the wall behind the appliance (non-perimeter wall), a hole must be made in an external wall of the room where the appliance is positioned.

If it is not possible to create the fresh air intake in the room, an external hole can be created in an adjacent room provided it is permanently interconnected by means of a transfer grille.

It is prohibited to withdraw combustion air from a garage, warehouse containing combustible materials or rooms at risk of fire.

If one or more extraction fans (extractor hoods) are present and operating in the installation room, combustion malfunctions may occur due to lack of combustion air.

The combustion air intakes must therefore be correctly sized in order to guarantee the necessary supply of air for the correct operation of all devices.

6.5 Flue gas fitting

The appliance works with the combustion chamber at negative pressure. It is therefore essential to make sure that the flue gas evacuation is airtight (this is the responsibility of the installer).

The appliance must be connected to its own flue gas duct, not shared, and which is suitable for ensuring adequate dispersion of the combustion products into the atmosphere, in accordance with the regulations in force in the country of installation.

The components making up the flue gas ducting system must be declared suitable for the specific operating conditions and provided with CE marking.

It is mandatory to create a first vertical section measuring at least 1.5 meters to guarantee correct expulsion of the flue gases.

It is advisable to make a maximum of 3 direction changes, in addition to that resulting from the rear connection of the appliance to the chimney, using 45 - 90° bends or Tee fittings (Fig. 16).

Always use a Tee fitting with inspection cap at each horizontal and vertical change of the flue gas route (Fig. 16).

The horizontal sections must have a maximum length of 2-3 m with an upward slope of 3-5% (Fig. 16).

Anchor the pipes with suitable collars to the wall.

The flue gas fitting MUST NOT BE connected:

• to a chimney used by other generators (boilers, stoves, fireplaces, etc. ...);
• to air extraction systems (hoods, vents etc. ...) even if "ducted".

It is forbidden to install shut-off and draught valves.

MAX 2 - 3 m C > 3 - 5% MIN 1,5 m Fig. 16

On the first vertical tee, at the flue gas outlet of the appliance, a pipe must be connected at the bottom to drain any condensate that may form in the chimney (Fig. 17).

The flue gas evacuation duct must be equipped with its own earth connection.

7.4 Fuel optimisation

Excellent fuel depends on different factors (type of installation, operating and maintenance conditions, type of pellets, etc.)

Upon first ignition, the stove can be regulated for optimum combustion performance. Generally speaking, if at the end of combustion, there is a lot of residue in the burn pot, you should change the combustion configuration (by increasing the value) until you find the best solution.

Please refer to the submenu [14] "Combustion" of the use and operation manual.

Depending on the type of installation it is necessary to set up the ideal configuration for correct operation.

8.1 Configuration 1 - Room sensor

Room temperature probe Fig. 22

Configuration 1 is the default configuration for this appliance. In this case it is not necessary to make any changes.

The appliance leaves the factory with the room probe positioned on the rear panel (Fig. 22).

It is possible to place the room probe in another place to detect the desired room temperature.

Set configuration 1 to switch the appliance on and off either manually or according to a program.

The appliance modulates the power according to the room temperature read by the room probe placed on the stove itself.

You can set the "Eco-mode" function to have the appliance switch off or on again according to the room temperature set.

The antifreeze function can also be set in this configuration.

It is important to check that the appliance is set to Configuration 1.

This configuration can also be used to switch the appliance on and off manually or in a programmed way (with the Timer function active).

10.4 Ordinary cleaning

10.4.1 Cleaning the inside of the firebox

Daily or before each ignition, it is necessary to check that the burn pot is clean to ensure the free flow of combustion air from the holes of the burn pot itself.

Vacuum the ash accumulated in the burn pot (Fig. 26).

Remove the ash from the combustion chamber as the salts present cause corrosion of the metal. In addition, the ash could block the passage of air, varying the development of the flame which, if it approaches the glass, would increase corrosion.

After cleaning the burn pot, remove it from its housing and clean the space where it is contained (Fig. 26).

A B Indicative image Fig. 30

10.5.3 Maintenance of the smoke system

If there are horizontal sections, it is necessary to check and remove any deposits of ash and soot before they obstruct the passage of fumes.

The incrustations inside the flue affect the optimum forced draught. When they reach a thickness of 5-6 mm, with high temperatures and sparks, they can ignite with easily imaginable consequences both for the flue and for the house.

In the event of failure to clean or inadequate cleaning the appliance may have operating problems including:

• bad combustion;
• blackening of the glass;
• blockage of the burn pot with accumulation of ash and pellets;
• deposit of ash and excessive deposits on the exchanger with consequent poor performance.

10.5.4 Appliance maintenance

To be carried out at least once a year, or every time the appliance signals maintenance request.

During the maintenance operation, the technician must:

• clean the flue gas transit area thoroughly and completely;
• check the condition and tightness of all the seals;
• check the condition of all internal components and make sure they are clean;
• make sure the flue gas outlet connection is sealed and clean;
• remove any deposits of pellet residues in the tank;
• check that there are no pellets or pellet residues in the appliance installation space;
• check the correct operation of the appliance;
• reset any warnings or alarms.
