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.
Minimum dimensions (Picture 9 at page
A – natural convection:
B – forced convection:
* (For a better comfort and corresponding oxygenation of environment, the combustion air can be directly withdrawn at the outside through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 Picture 9 at page
with the outside it must be endowed with a special windbreak.)

6. VENTILATION HOOD OR ADJACENT LOCAL

In order to distribute the heating in the environment or carry it to an adjacent room it is possible to install a galvanized steel covering
(OPTIONAL) on the external cast-iron body of the same appliance.
The covering is provided with 4 outlets with a 150 mm diameter to connect the heat resistant pipes. This covering is fixed to the fireplace
through special screws:
a) Perform the drilling on the walls or on the existing hood to allow the passage and the application of the (fire-resistant) hoses with a
15 cm diameter equipped with related openings.
b) Fasten the pipes by means of clamps to the related collars and openings, (see
c) Each pipe must not exceed 2m of length for natural ventilation and 4m for forced ventilation; it must 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
f) The OPTIONAL ventilation kit has to be installed below the appliance in the rear part (see instructions in chapter OPTIONAL kit
ventilation). As consequence you should arrange a underlying space to collocate it, allowing a proper air flow and the accessibility
for future maintenance.

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 (Picture 12 at page 45
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.
