10. CONNECTION AND MAINTENANCE OF VENTILATION

The control unit and the plant must be installed and connected by authorized personnel according to the standards in force (see
chapter GENERAL PRECAUTIONS).
ATTENTION: the control unit and the feeding cable must not be in contact with hot parts.
On our products, it is possible to install ventilation kits suitable to improve the distribution of heat by ventilation only either of the installation
room or of the adjacent local (see chapter CANALIZATION).
For the connection of the ventilation kit, please see
The Kit is made up of a centrifugal fan, a lighting and adjustment control unit, and a (TM) thermostat that lets the fan start when the device
is properly heated and lets it stop when the fan is partially cold.
The lighting and the adjustment is carried out through the proper standard supplied control unit that has to be installed far from any direct
heat source.
CONNECTION: Connect the power supply cable of the control unit to a bipolar switch respecting at least a 3 mm distance between the
contacts (power supply 230V~ 50/60 Hz, it is necessary to provide for the correct connection to the grounding plant).
WARNING: The COMMAND must be connected to the mains with a differential line cut-off switch according to the regulations
in force. Correct operation of the command is assured only for the proper motor for which it has been manufactured.
Improper use relieves the manufacturer from each responsibility.

11. 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
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 appliance and the flue, causing health damages and claims by
the neighborhood owing to the bad smell. The wood is not a fuel which allows a continuous operation of the appliance, as consequence
the heating all over the night is not possible.

ATTENTION : the continuous and protracted use of aromatic wood (eucalyptus, myrtle etc.) quickly damages the cast iron parts
(cleavage) of the product.

12. LIGHTING

WARNING: After the first ignition you can smell bad odours (owing to the drying of the glue used in the garnitures or of the paint) which
disappear after a brief using of the appliance. It must be ensured, in any case, a good ventilation of the environment. Upon the
first ignition we suggest loading a reduced quantity of fuel and slightly increasing the calorific value of the equipment
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 - 500°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;
