2.4.7 CHARACTERISTICS OF THE PELLETS
Description Unit of measurement Value
Size of the pellets mm 6 – 8
Recommended net calorific value MJ/kg >17.2
kWh/kg >4.7
Class (ENplus) ENplus-A1
Pellet category A, AB, B*
Ash residue % See Table 2
Humidity % Max. 8 – 10%
Table 1
Properties recommended for wood pellets
* The automatic pellet burner is designed to use wood pellets with the properties described in the ENplus reference standard. As an
alternative, ONLY FOR A LIMITED NUMBER OF HOURS, it is possible to use pellets that do not comply with the requested class. In this
case the fuel, being of lower quality, will generate a high ash residue, which will result in the need for more frequent cleaning of the
burner grille and the heat exchanger walls.
