for future maintenance.

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 OF OPTIONAL VENTILATION KIT.

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.
