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 600
kg/m3 and 750 kg/m3, with a moisture content which varies from 5%
to 8% by weight.
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,
therefore after about 18 months' seasoning), the equivalent figure for
pellets is 4.9 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 main certifications of quality for pellets in the European market are
DINplus and Ö-Norm M7135; these ensure respect of:
Calorific power: 4.9 kWh/kg
Water content: max 10% of weight
Percentage of ashes: max 0,5% of weight
Diameter: 5 – 6mm
Length: max 30mm
Contents: 100% untreated wood, with no added bonding
substances (bark percentage 5% max)
Packaging: in sacks made from ecologically compatible or
biologically decomposing material
Fuel pellets

Theoretical notions for installation Technical service - Rights reserved - Reproduction prohibited
The company strongly recommends the use of
certified fuel for its stoves (DINplus and Ö-Norm
M7135).
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.
Pellet stoves only work with pellets having a
diameter of 6-8 mm with a length ranging from 5mm
to max 30 mm.
2.2. PRECAUTIONS FOR INSTALLATION
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
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.
PELLET STOVES Chapter 2
red
INSTALLATION AND USE MANUAL

Theoretical notions for installation Technical service - Rights reserved - Reproduction prohibited
2.3. OPERATING AREA
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
3
/h must be
available), as laid down 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
3.
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 particular reference to what is laid
down in current standards.
It is not permissible to install the stove in bedrooms,
bathrooms, 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.
2.3.1. Safe distances
If the room contains objects which are believed to be particularly
delicate, such as drapes, sofas and other furniture, their distance from
the stove should be considerably increased.
If the floor is wooden, we recommend the use of a
floor guard in compliance with the applicable
standards in force in the country of installation.

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 ducts.
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 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.

2.5. CONNECTION OF SMOKE DISCHARGE PIPE
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 has to pass through a wall made of wood or
thermolabile material, THE FITTER MUST under all circumstances
observe the minimum safe distance from all combustible materials
(value stated on the pipe certification label) and provide any additional
insulation using appropriate materials (thickness 1.35cm 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 accessories for
pellet stove)
It is absolutely prohibited to fit a grille on the end of
the discharge pipe, because it could lead to poor
running 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
IT IS ALSO ADVISABLE NOT TO EXCEED 6 METRES IN
LENGTH WITH THE PIPE Ø 80 mm

2.6. CONNECTION TO THE FLUE PIPE
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.
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 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.
2.7. 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.
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.
2.8. CONNECTION TO THE FLUE PIPE
For proper functioning, the connecting pipe between the stove and the
chimney or flue duct must have a slope of not less than 3% in the
horizontal stretches, the length of which must not exceed 2/3
metres, and the vertical distance between one tee connector and
another (change of direction) must not be less than 1.5m.
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 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.
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
y
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 personnel.

2.10. PLUMBING CONNECTION
IMPORTANT!
The connection of the stove to the plumbing system
must be carried out ONLY
by specialized personnel
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.
The Company 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.
For connection of the plumbing system to the stove, the user should
refer to chapter 3, INSTALLATION AND ASSEMBLY; specifically,
paragraph 3.4, CONNECTION TO PLUMBING SYSTEM
