The wood pellet is obtained by pressing wood sawdust left over from
the working of natural dried wood. The typical small, cylindrical form
is obtained by passing the material through a die. Thanks to lignin,
a natural element which is released during the pressing of the raw
material, the pellets acquire a good consistency and compactness
without requiring treatment with additives or caking agents. There are
various types of pellet on the market with qualities and characteristics
that vary depending on the processes they have undergone and the type
of wood used in their production.
Since the characteristics and quality of the pellet considerably affect
stove performance, efciency and proper operation, we recommend
that you use high-quality pellets.
Gruppo Piazzetta S.p.A has tested and programmed its stoves and can
ensure best performance and trouble-free operation using pellets with
the following specic characteristics:
Pellet characteristics
Components natural pure wood pellet
Length, approx. 10 - 30 mm
Diameter, approx. 6 - 6,5 mm
Apparent density, approx. 650 kg/m
3
Specic weight, approx. > 1,0 kg/dm
3
Net heat value, approx. 5 kWh/kg
Moisture content, approx. < 8%
Residual ash, approx. < 0,5%
N.B. the above data refer to beech/r wood pellets
To ensure trouble-free operation:
DO NOT use pellets with dimensions other than those recommended by
the manufacturer.
DO NOT use poor quality pellets containing sawdust, bark, maize, resins
or chemical substances, additives or adhesives.
DO NOT use damp pellets.
To prevent accidents or damage to the product we recommend the following:
- unpacking and installation must be carried out by at least two people;
- every operation involving movement of the product must be carried out with the proper tools in full compliance with current safety regulations;
- the packaged product must be kept in the position according to the directions shown by the diagrams and notices on the pack;
- if ropes, straps or chains are used, ensure that they are able to take the weight of the pack and that they are in good condition;
- use slow continuous movements when moving the pack to avoid jerking the ropes, chains, etc.;
- do not tilt the package excessively to avoid toppling;
- never stand in the vicinity of loading/unloading equipment (forklift trucks, cranes etc).
a Unpack the product being careful not to damage or scratch it, take the accessories pack and any pieces of polystyrene or cardboard
used to wedge moveable parts etc. out of the stove rebox.
Keep packaging (plastic bags, polystyrene, etc.) out of reach of children, since it could be a potential source of danger, and dispose
of according to local regulations.
Choosing other and unsuitable pellets:
- obstructs the grate and ue gas pipes;
- increases fuel consumption;
- reduces efciency;
- means that proper stove operation cannot be guaranteed;
- causes dirt to build up on the glass;
- leaves particles which have failed to burn and heavy cinders.
The presence of moisture in the pellets increases their volume and
causes them to split which in turn causes:
- malfunction of the fuel-loading system;
- inefcient combustion.
Pellets should be stored in a sheltered, dry place.
To use good quality pellets with dimensions and heat-producing
properties other than those recommended above, it will be necessary to
change the stove operating parameters.
a This “customisation” of stove settings must be carried out
at a Gruppo Piazzetta S.p.A. Service Centre or by specially
qualied personnel authorised by Gruppo Piazzetta S.p.A.
a Using pellets that are out of date or not in conformity with
the manufacturer’s recommendations not only damages the
stove and jeopardises its performance, but can render the
guarantee null and void and relieves the manufacturer of all
liability.
