CONNECTION AND MAINTENANCE OF VENTILATION (OPTIONAL)
The control unit and the plant must be installed and connected by authorized personnel according to the standards in
force. (see chapter GENERAL REMARKS).
ATTENTION: the control unit and the feeding cable must not be in contact with hot parts.
On our products, it is possible to install Optional ventilation kits suitable to improve the distribution of heat by ventilation only either of the
installation room or of the adjacent local (see chapter EXTERNAL AIR INTAKE).
For the connection of the ventilation kit, please see the instructions manual CONNECTION AND MAINTENANCE OF VENTILATION OPTIONAL.
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.
The declared technical data have been achieved by burning beech wood class "A1" according to the requirement UNI EN ISO 17225-5 and wood
moisture content less than 20%. By burning a different kind of wood the efficiency of the product itself could change and some specific adjustments
on the appliance could be needed.
LIgHTINg
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. A good ventilation of the room should always be guaranteed.
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.
Open the primary air completely.
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 close the primary
air register and control the combustion through the secondary air register according to the provisions of chapter TECHNICAL DESCRIPTION.
Please always be present during this phase.
Never overload the appliance (see cap.TECHNICAL DESCRIPTION - Hourly consumption).
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;
