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/m3. Due 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.
Ravelli 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.
! IMPORTANT
The use of pellets with different characteristics than that tested by the technician during the 1st ignition implies a new calibration of
the pellet boiler parameters of the boiler, such intervention is excluded from the warranty.

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, both during transport
and during storage.
