Fuel
The boiler must be exclusively fuelled by pellets. No other fuel may be used.
Use only pellets 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 section Menu configurations - transient and
power operations).
Warning!
The unit must NOT be used as an incinerator.
