bustion efficiency and conserves the moving mechanical parts
of the appliance.
If you plan on not using the PELLEXIA boiler
for a long period of time (seven days or more),
you should remove any residual fuel in the
tank which, if left inside, could gather mois-
ture and cause the product to malfunction.
A high moisture content in the pellet can
cause it to break up into powder generating
a greater accumulation of residue in the brazier
and a blocking of the fuel feed system (feeding
screw).
The pellets, as foreseen by current
Italian legislation governing commodity
features of fuels (DPCM 2.10.1995), must
be produced exclusively with untreated
wood sawdust without other materials
added.
It is absolutely forbidden to use any solid
or liquid fuel other than pellets to feed
PELLEXIA.
It is advisable to use certified pellets to ensure
optimal use of PELLEXIA.
The use of poor quality pellets can cause
PELLEXIA malfunctioning and shall terminate
the warranty.
Storage and handling of pellets are important
operations to be performed with care:
- The fuel must be stored in a dry place which is not cold;
- Pellets must be moved in such a way to avoid excessive crush-
ing into fine powders.
Compliance with these two simple rules provides better com-
