N.B.: The smoke side of the thermal exchange pipes becomes dirty; it is therefore
advised, every time you load pellets, to activate the scraper system (pos. 8) in the
opposite vertical direction for a few seconds to keep them clear.
2.6 - GENERAL INFORMATION
The main feature of the STILE 27 heat stove is that of burning
natural fuel (pellets) obtained in an environmentally-friendly
way from wood industry waste (sawdust, powders). The
sawdust and powders coming from wood processing, after
having been appropriately cleaned and dried, are compacted
at high pressure giving way to pure wood cylinders: the pellet.
Each cylinder can have variable length and thickness,
respectively, between 1÷3 cm long and 6÷8 mm in diameter.
The main features of the pellet are its low moisture content
(lower than 12%), its high density (about 600 kg/m
3
) as well
as its regularity and compactness providing this type of fuel a
Net Calorific Value (NCV) of 4100÷5000 kcal/kg.
In order to provide STILE 27 with a long lifespan, Unical advises
using good quality pellets.
The pellets used to feed the heating stove must have high
quality features such as, for example, those determined by
standards DIN 51731 and ÖNORM M 7135. The following a
some of their fundamental data.
