Fuel
The boiler must be exclusively fuelled by pellets. No other fuel may be
used.
Use onlypellets certified by standard EN 14961-2 grade A1, 6mm
in diameter and a length between 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 they should be stored in a dry place.
The use of pellets of varied quality reduces the boiler's efficiency and
leads to an inadequate combustion process.
You should always use certified pellets and must not forget to test
a sample before buying large bulks.
The physical/chemical properties of the pellets (calibre, friction, density
and chemical composition) may vary within specific tolerances and
according to each manufacturer. Please note that this may cause
alterations to the feeding process and, consequently, the need for different
doses (more or less pellets).
The boiler's pellet dosage can be adjusted during the start-up
phase and at the power thresholds of± 25% (see the manual –
temporary and power settings)
Warning!
The unit must NOT be used as an incinerator.
