2-INSTALLATION

The instructions in this chapter refer explicitly to the Italian installation regulation UNI 10683. In any case, always
observe the regulations in force in the country of installation.
PELLETS
Wood pellets are manufactured by extruding sawdust which is produced during the processing of natural dried wood (without paint).
The compactness of the material is guaranteed by the lignin contained in the wood itself and allows the pellets to be produced without
glue or binders.
The market offers different 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 3 to 40 mm. A good quality pellet has a density of between 600 and 750 or
more kg/cubic metres and a moisture content that accounts for 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.
While good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), that of pellets is around
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 need to
be cleaned.
The main quality certifications for pellets currently available on the European market guarantee that the fuel complies with class A1/A2
according to ISO 17225-2 (ex EN 14961). These certifications include, for example, ENPlus, DINplus, Ö-Norm M7135, and specifically
assure that the following characteristics are complied with:
•
calorific value: 4.6 - 5.3 kWh/kg.
•
Water content: ≤ 10% of the weight.
•
Percentage of ash: max 1.2% of the weight (A1 less than 0.7%).
•
Diameter: 6±1/8±1 mm.
•
Length: 3-40 mm.
•
Content: 100% untreated wood without the addition of binding agents (max 5% bark).
•
Packaging: in sacks made from ecologically compatible or biologically decomposing material.
The company strongly recommends using certified fuel for its products (ENplus, DINplus, Ö-Norm M7135).
Poor quality pellets or others that do not comply with the characteristics specified previously may compromise the
operation of your product and can therefore make the guarantee and product liability invalid.
