Instructions for installation, use and maintenance – EN – Rev.07
9. ALLOWED / NOT ALLOWED FUELS
Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 3 logs should be
loaded. The pieces of wood should have a length of ca. 20-30 cm and a maximum circumference of 30-35
cm.
Compressed not worked-out wood briquettes must be used carefully to avoid overheating that may
damage the device, since these have a very high calorific value.
The wood used as fuel must have a humidity content lower than the 20% and must be stored in a dry
place. Humid wood tends to burn less easily, since it is necessary a greater quantity of energy to let the
existing water evaporate. Moreover, humid content involves the disadvantage that, when temperature
decreases, the water condensates earlier in the hearth and therefore in the stack causing a remarkable
deposit of soot with following possible risk of fire of the same.
Fresh wood contains about 60% of H
2
O, therefore it is not suitable to be burnt.
It is necessary to place this wood in a dry and ventilated place (for example under a roofing) for at least two
years before using it.
Besides others, it is not possible to burn: carbon, cuttings, waste of bark and panels, humid wood
or wood treated with paints, plastic materials; in this case, the warranty on the device becomes
void.
Paper and cardboard must be used only to light the fire. The combustion of waste is forbidden and would
even damage the device.
ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly
damages the cast iron parts (cleavage) of the product.
10. LIGHTING
To light the fire, it is suggested to use small wood pieces together with paper or other traded lighting
means.
It is forbidden to use any liquid substance as for ex. alcohol, gasoline, oil and similar.
When wood starts to burn, it is possible to feed it again by opening slowly the door, in order to avoid leaks
of smoke, and adjust the air for the combustion according to the provisions of CHAP. 11.
Never overload the appliance (see the technical table - max. quantity of fuel that can be loaded / hourly
consumption – (see CHAP. 17).
Too much fuel and too much air for combustion can cause overheating and therefore damage the
same.
Never switch on the device when there are combustible gases in the room.
To perform a correct first lighting of the products treated with paints for high temperature, it is necessary to
know the following information:
•
the construction materials of the involved products are not homogeneous, in fact there are
simultaneously parts in cast iron, steel, refractory material and majolica;
•
the temperature to which the body of the product is subject is not homogeneous: from area to area,
variable temperatures within the range of 300°C - 5 00°C are detected;
•
during its life, the product is subject to alternated lighting and extinguishing cycles in the same day, as
well as to cycles of intense use or of absolute standstill when season changes;
•
the new appliance, before being considered seasoned has to be subject to many start cycles to allow
all materials and paints to complete the various elastic stresses;
•
in detail, initially it is possible to remark the emission of smells typical of metals subject to great thermal
stress, as well as of wet paint. This paint, although during the manufacture it is backed at 250 °C fo r
