ALLOWED / NOT ALLOWED FUELS

Allowed fuels are logs. Use exclusively dry logs (max. content of water 20%). Maximum 2 or 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.
The not worked-out compressed logs must be used with care to avoid overheating that may
damage the appliance, since these have a 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
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 appliance becomes
void.
Paper and cardboard must be used only to light the fire.
The combustion of waste is forbidden and would even damage the appliance.
ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly
damages the cast iron parts (cleavage) of the product.

LIGHTING

Place the lever of the smoke valve totally to the left (all open). (see CHAP.2 pt. 3)
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. 12.
Position the lever of the smoke valve back to the right (all closed).
Never overload the appliance (see the technical table - max. quantity of fuel that can be loaded / hourly
consumption – (see CHAP. 18).
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
some hours, must exceed many times and for a given period of time the temperature of 350 ° C before
becoming completely embedded in the metallic surfaces.
Therefore, it is extremely relevant to take these easy steps during the lighting:
1) Make sure that a strong air change is assured in the room where the appliance is installed.
2) During the first starts, do not load excessively the combustion chamber (about half the quantity
indicated in the instructions manual) and keep the product continuously ON for at least 6-10 hours with
the registers less open than the value indicated in the instructions manual.
