the regulations in force in the country of installation
PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the processing of natural dried wood
(without paints). The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets to be
produced without glue or binders.
The market oers dierent types of pellets with characteristics that vary according to the wood mixtures used. The diameter varies
between 6 and 8 mm, with a standard length ranging from 5 to 30 mm. Good quality pellets have a density that varies between 600 and
over 750 kg/m3, with a moisture content that ranges from 5% to 8% of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving cleaner
combustion than that of fossil fuels.
Good-quality wood has a caloric value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets is 4.9
kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually supplied in 15 kg
bags, therefore, storing them is very convenient.
Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.
The poorer the quality of the fuel, the more often the internal parts of the brazier and combustion chamber must
be cleaned.
DINplus, Ö-Norm M7135 and Pellet gold are examples of the major quality certications of pellets in the European market and
guarantee that the following are complied with:
tcaloric value: 4.9 kWh/kg.
tWater content: max 10% of the weight.
tPercentage of ash: max 0.5% of the weight.
tDiameter: 5 – 6 mm.
tLength: max 30 mm.
tContent: 100% untreated wood with no added binding agents (max percentage of bark: 5%).
tPackaging: in bags made from environmentally friendly or biologically decomposable material.
The company strongly recommends using certied fuel for its products (DINplus, Ö-Norm M7135 or Pellet Gold).
Poor quality pellets or others that do not comply with that specied previously compromises the operation of your
product and can therefore render the warranty and product liability null and void.

The product must be connected to a chimney or an internal or external vertical duct that complies with the regulations in
force.The product must be positioned in such a way that the electrical socket is accessible.
IMPORTANT!
The product must be connected to a chimney or a vertical duct that can expel the smoke at the highest point of the
building.
In any case smoke derives from combustion of types of wood and if it comes in contact with or close to walls, these
can become dirty. Moreover, utmost attention is required as they are almost invisible but very hot and can cause
burns. The holes of the external air inlet and the smoke outlet pipe must be drilled before positioning the product.
THE OPERATING ENVIRONMENT
For correct operation and even distribution of heat, the product must be placed where the air required for combustion can ow.
The volume of the room should be no less than 15 m3.
The air must come in through permanent openings made in walls (in proximity to the product) which lead to the outside, with a minimum
cross-section area of 80 cm2, without the protective grilles.
These openings (air inlets) must be made in such a way that it is impossible for them to be obstructed in any way.
Air can also be drawn from adjacent rooms to the one that is to be ventilated, provided they have an external air inlet and are not used as a
bedroom or bathroom or where there is a re hazard, such as: garages, timber storerooms, warehouses of ammable materials, observing
under all circumstances the provisions of all the applicable standards in force.
If the product is placed too close to the wall it could cause overheating and damage the plaster (yellowing, cracking,
etc.).
POSITIONING AND RESTRICTIONS
In the case of simultaneous installation with other heating appliances, provide appropriate air inlets for each one (according to the
instructions of each product).
The product cannot be installed (except for sealed or closed operation appliances with external ducted combustion
air intake):

CONNECTION TO THE EXTERNAL AIR INLET
It is essential for the room where the product is installed to be adequately ventilated in order to guarantee sucient air for proper
combustion in the appliance.This can be set up using suitable ventilation openings in the same room or one that connects through a
permanent opening between the rooms.
For this purpose, drill a hole on the outer wall close to the product with a minimum section of 80 cm² (11 cm in diameter or 10x10 cm if
rectangular, considering the protective grilles), protected by a grille on the outside.
The air inlet must also:
tbe protected with a grid, metal mesh, etc. without reducing the net section.
tBe positioned in such a way so as not to be obstructed.
tAllow maintenance to be performed.
tBe directly interconnected with the room where the product is installed.
tIn the case of ducting, up to 3.5 linear metres, increase the cross-section by about 5%, whereas for longer ducts, increase it by 15%.
Remember that the ventilation grilles always show the useful section in cm2on one side. When choosing the grille
and size of the hole, check that the useful section of the grille is larger or equal to the section required by the
company for product operation.
IMPORTANT!
The air ow can also be drawn from an adjacent room to that of the room where the product is installed, provided
the aircan owfreelythroughpermanent openings interconnectedwiththeoutside;airinletsconnected to thermal

OPERATING PROBLEMS RELATED TO DRAUGHT DEFECTS IN THE CHIMNEY
Among all the weather and geographical conditions that aect chimney operation (rain, fog, snow, altitude a.s.l., exposure to sunlight,
orientation to the cardinal points, etc.), the wind is certainly the most determinant. In fact, besides the thermal depression caused by
the dierence in temperature between inside and outside the chimney, there is another type of depression (or overpressure): dynamic
pressure caused by the wind. An updraft always increases depression and therefore the draught. A horizontal wind increases depression
provided the chimneypot has been installed properly. A downdraft always decreases depression, at times inverting it.
Besides the direction and force of the wind, the position of the chimney and the chimneypot with respect to the roof of the building and
the surrounding landscape is also important.
The wind also aects chimney operation indirectly by creating overpressure and depression zones within the building as well as outside.
An internal overpressure can be created in rooms that are directly exposed to the wind (2), which can enhance the draught in stoves and
replaces, however, it can be counteracted by the external overpressure if the chimneypot is situated on the side exposed to the wind
(1). On the other hand, a dynamic depression can be created in rooms that are opposite the wind direction (3), which competes with the
natural thermal depression generated by the chimney, however, this can be compensated for (sometimes) by placing the smoke duct
opposite the wind direction (4).
IMPORTANT!
The operation of the pellet product is signicantly aected by the chimney layout and position.
Hazardous conditions can only be resolved by qualied personnel setting the product appropriately.

4-INSTALLATION AND ASSEMBLY
The stove body or unit must always be kept in a vertical position when handled and moved by using carts only. Pay particular attention to
the door and its glass, protecting them from mechanical knocks that would compromise their integrity. Always handle the product with
care. If possible, unpack the stove near the chosen place of installation.
The packaging materials are neither toxic nor harmful, and therefore no particular disposal measures are required. Therefore, the end user
is responsible for product storage, disposal or possible recycling in compliance with the relative applicable laws.
Do not store the stove unit or its cladding without their packaging.
Position the stove without its cladding and connect it to the ue pipe. Use the four adjustable feet (J) to get the stove correctly levelled so
that the smoke outlet (S) is lined up with the connecting pipe (H). Once the connection operations are complete, assemble the cladding
(ceramics or steel sides).
If the stove needs to be connected to a discharge pipe which goes through the rear wall (to then connect to the ue), take utmost care
not to force the joint.
If the stove smoke outlet is forced or used improperly to lift it or position it, the operation of the stove can be
damaged irreparably. 563/5)&'&&5$-0$,8*4&50-08&35)&4507&563/5)&'&&5$06/5&3$-0$,8*4&503"*4&5)&4507&
