100% pressed pine wood pellets certified
according to the EN PLUS A1 standard are the
only fuel allowed for use in this boiler .
The pellets used must be certified and in
accordance with EN Plus 14961 or 17225-2.
5.1. Fuel characteristics
Pellets are produced by pressing wood chips and
sawdust. They are obtained without the addition
of any foreign substance, such as adhesives,
lacquers or synthetic substances.
Pressing through a matrix of holes and the heat
produced by friction and pressure, activates
natural wood binders that in this way ensure the
shape of the pellets even without the addition of
binders.
The production and consumption of pellets is
based on the rational use of renewable energy
with zero impact on the CO
2 cycle
, which respects
environmental protection standards.
This is the only fuel indicated for this equipment.
Yield and power vary depending on the quality of
pellets used.
For correct operation you must use pellets
according to the characteristics below.
