FUEL CHARACTERISTICS
d
It is forbidden to use any fuel other than wood.
DO NOT USE wood that has is very humid, wet or sea-
■
soned for less than 2 years.
DO NOT USE wood with a high resin content as this
■
may shorten the appliance working life and require
more frequent cleaning of the flue and of the appli-
ance.
Since the characteristics and quality of the wood considerably influ-
ence product autonomy, yield and proper operation, the manufacturer
suggests using well seasoned (at least 2 years) and dry wood, with
humidity between 10÷15%.
Wood is divided into softwood (e.g. fir, pine, poplar, alder, chestnut,
willow) and hardwood (beech, ash, hornbeam, locust and oak). Soft-
wood ignites easily, burns quickly and has a long flame. Hardwood
is more compact and burns more slowly with a short flame; it lasts
longer and is more suitable for domestic heating systems.
Depending on the calorific value of the wood, its composition and
consistency, and the flame duration, wood to burn can be classified
into two categories: "good quality" and "poor quality".
Good-quality fuel
The following hardwoods are regarded as suitable: beech, ash, horn-
beam, oak, locust, birch, maple and elm.
Poor-quality fuel
The following softwoods should not be used: willow, poplar and alder.
a
The use of poor-quality wood or any other material
can damage the appliance functions and void the
warranty, resulting in the manufacturer being ex-
empted from all liability.

Size of the wood
The dimensions and arrangement of the wood logs also influence
product performance. It is important that the wood:
- is cut into pieces adequate to the size and type of the firebox so that
it does not rest against the walls or glass of the door
- is properly arranged on the brazier and above a layer of embers
- is in contact with the embers for a surface as large as possible,
preferably free of bark.
For the dimensions and arrangement of the fuel, refer to the
ing the
fuel" chapter.
4.2
STORAGE
l
To ensure optimal combustion the wood must be
stored in a dry and covered place, sufficiently far
away from the appliance and from heat sources that
may trigger combustion.
a
The room chosen to store the pellets must not be
used as a warehouse for flammable substances or
for activities subject to the risk of fire.
The wood MUST be transported and stored strictly in
■
a way that ensures it remains dry at all times.
