Fuel
The Free Standing Pellet Fire operates exclusively with pellets. No other fuel sources
are allowed to be used.
Only use
pellets
certified by standard EN 14961-2 grade A1 with a
diameter of 6mm
and a length of
10-30mm
.
The pellets may have a maximum humidity of 8% their weight. To guarantee a good
combustion, the pellets must maintain these characteristics so it is recommended that
they should be stored in a dry place.
The use of different pellets will reduce the efficiency of the unit and cause deficient
combustion.
Only certified pellets should be used and a sample must be tested before
buying large bulks.
The physicochemical properties of the pellets (namely, calibre, friction, density and
chemical composition) may vary within specific tolerances and across manufacturers.
Please note that this may cause changes to the feeding process and, consequently, the
need for different doses (more or less pellet quantity).
The unit allows for an adjustment of +15%/-33% the pellet dosage at the
start-up phase and at each power level
(please see section 9.2.7 of this manual)
.
WARNING!
This unit may NOT be used as an incinerator.
