6.4.

EXTERNAL AIR INTAKE

There MANDATORY be sufficient quantity of air for combustion and re-oxygenation of the room to ensure the device will work properly.
There should therefore be vents letting air in from outside the building and enabling circulation of air for combustion even when the doors
and windows are closed.
• The air intake must be in a position where it cannot be obstructed.
• The air intake should communicate with the room in which the device is installed and be protected with a grille.
• Vents may communicate with adjacent rooms but NOT with garages, kitchens, bathrooms or boiler rooms (FORBIDDEN).
• Any extractor hoods in the room where the device is installed must NOT operate at the same time as this could cause smoke to
enter the room, even with the fireplace's door closed.

* (For a better comfort and corresponding oxygenation of environment, the combustion air can be directly withdrawn at the outside through
a junction (B1) which is to be connected with a flexible pipe (not furnished)for the external air intake. The connection pipe must be flat with

a minimum diameter of (B1
with the outside it must be endowed with a special windbreak.)

7. 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.
