5�4 CHARACTERISTICS OF THE FUEL
Wood pellet is a fuel made of pressed wood sawdust,
often recovered from processing scraps of carpentries.
The material used cannot contain any extraneous
substance such as, for example, glue, lacquer or synthetic
substances.
The sawdust, once it has been dried and cleaned from
impurities, is pressed using a die with holes: as a result of
high pressure, the
sawdust heats up by activating the natural wood binders;
this way the pellet maintains its shape even without
adding artificial substances.
Wood pellet density varies based on the type of wood and
can exceed that of natural wood by 1.5 - 2 times.
The cylinders have a diameter of 6 mm and a variable
length between 10 and 40 mm.
Their density is equal to approximately 650 kg/m
to their low water content (< 10%) they have a high
energy content.

The UNI EN ISO 17225-2:2014 standard (that replaces
the EN PLUS standard) defines pellet quality by
specifying three classes: A1,
A2 and B. Maintain fuels and other flammables at a
suitable distance.
Jotul recommends using wood pellet classified A1 and
A2 according to the EN ISO 17225-2:2014 standard, or
certified DIN PLUS
(more restrictive than the A1 class) or ONORM M 7135.
Pellet may be light or dark coloured, it is normally bagged
into bags that show the name of the producer, the main
characteristics and classification according to standards.
Pellets must be transported and stored in a dry area� Upon
contact with humidity they swell and become unusable�
It is therefore necessary to protect them from humidity,
