The pellets are tiny cylinders of pressed wood,
produced from sawmill and wood processing
residues (chips and sawdust).
The pellets, as foreseen by current Italian
legislation governing the commercial features
of fuels, must be exclusively produced with
untreated wood sawdust, without any other
added materials.
The binding capacity of lignin, which is contained
in wood, allows a compact product to be obtained
without adding any additives and foreign
chemicals to the wood, thus obtaining a natural,
high yield fuel.
Using low grade pellets or any other unsuitable
material may damage some boiler components
and affect proper operation: this may result in
Quality features of the pellets
voiding the warranty and relevant manufacturer
liability.
For our boilers exclusively use 6 mm diameter
pellets.
If the .it remains off for long periods of time, the
tank must be emptied from any residual fuel.
Store the pellets away from heat sources and not
in humid premises or with explosive atmosphere.
It is strictly forbidden to use any solid or
liquid fuel other than pellets to feed the .it.
