3. WHAT ARE PELLETS?
The pellets are made by applying very high pressure to sawdust, that is pure timber waste
(without paint), produced by sawmills, carpentry works and other activities associated with the
working and transformation of timber.
This type of fuel is completely environmentally friendly as no binders of any kind are used to keep
it compact. In fact, the compactness of the pellets over time is guaranteed by a natural substance
found in the wood itself: the lignite.
As well as being environmentally friendly, as the wood residues are exploited to the maximum,
pellets also have technical advantages.
While wood has a calorific power of 4.4
kW/kg. (with 15% humidity, after about 18 months seasoning) the power of pellets is 5.3 kW/kg.
The density of the pellet is 650kg/m3 and the water content is 8% of its weight. For this reason,
the pellets do not need to be seasoned to obtain an adequate calorific yield.
The pellet used must conform to the characteristics of the following regulations:
• Ö-Norm M 7135
• DIN plus 51731
• UNI CEN/TS 14961
Extraflame recommends always using 6 mm pellets for its products.
3.1 Pellet storage
To guarantee problem-free combustion, the pellet must be stored in a dry place.
3.2 Pellet loading
To load the pellets, open the tank cover positioned on the upper part of the stove and empty the
bag of pellets, paying attention not to let them escape.
WARNING
THE USE OF POOR QUALITY PELLETS OR OF ANY OTHER MATERIAL MAY DAMAGE THE
FUNCTIONING OF YOUR STOVE AND LEAD TO THE INVALIDATION OF THE WARRANTY
AND ASSOCIATED RESPONSIBILITIES
OF THE MANUFACTURER.
