always observe the regulations in force in the country of installation.
PELLETS
The pellet is obtained from natural dried wood sawdust (without paint). The compactness of the material is guaranteed by the lignin
contained in the wood itself, without glue or binders.
The market offers different types of pellets with characteristics that vary according to the wood mixtures. The most common diameter on
the market is 6 mm (although 8 mm diameter is also available) with a length, on average, between 3 and 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. 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.
The company recommends using certified fuel for its products (ENPlus A1, DINplus, Ö-Norm M7135).
The use of pellets that do not comply with the characteristics specified previously may compromise the operation of
your product and therefore invalidate the warranty and product liability.
