FOCOLARE 80 / 100 BIFACCIALE HYBRID
c) Each pipe must not exceed 2 m of length for natural ventilation and 4 m for forced ventilation, and has to be insulated with insulating
materials to avoid noise and dispersion of heat.
d) The openings have to be positioned at a height not lower than 2 m from the floor to avoid that hot air at output meets people. Please
respect the distance of the convection openings according to the local construction norms;
e) The lengths of the canalization pipes must have the same length to avoid the distribution of differing quantities of air from each
output (see Picture 10 at page

7. 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 installation of the Forced Ventilation Kit, follow the given instructions. (see chapter VENTILATION HOOD OR ADJACENT LOCAL).
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 (see chapter OPTIONAL VENTILATION KIT):
Connect the feeding cable of the switchboard with an electronic bipolar switch respecting at least a 3 mm distance between the contacts
(power supply 230V~ 50 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.

8. 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.
