Fumes evacuation
The appliances are divided into two types (see Table 1 – pag. 20):
Type "A1" gas appliances
It is not necessary to connect this type of appliance directly to an evacuation pipe for combustion
products. The products of combustion, however, must be directed into suitable hoods or similar
devices, connected to a reliably efficient chimney, otherwise directly outside. The use of an
extractor fan connected directly to external environment with a capacity no lower than what is
stated in table 1. This value must be increased with the air exchange necessary for the well-being of
the operators, in accordance with the norms in force. (approximately a total of 35 m
3
/h per KW of
gas output installed).
Type “B11” gas appliance
These appliances must be connected in one of the following ways:
•
Natural evacuation (fig.7 – pag. 4) .
Connection to reliable chimney with natural pull, interposing a pull device, letting out the
products of combustion directly outside.
•
Direct forced evacuation (fig. 8 – pag.4 ) .
Connection to a chimney with forced pull, putting in a pull device, letting out the products of
combustion directly into external environment. The energy supply to the appliance must be
controlled by the system of forced evacuation and must be interrupted in the event that its
capacity falls below the values prescribed by the norms in force. It must only be possible to
restart the gas supply manually.
•
Forced evacuation under hood (fig. 9 – pag. 4) .
In this case, the fumes evacuation device of the appliance must be brought to a height of 1,8 m
from floor level, and the outlet section of the evacuation pipes for products of combustion must
be placed inside the base perimeter of the hood. The energy supply to the appliance must be
controlled by the system of forced evacuation and must be interrupted in the event that its
capacity falls below the values prescribed by the norms in force. It must only be possible to
restart the gas supply manually.
INSTALLATION
Preliminary operations
Remove the appliance from the packaging, ascertaining that it is intact and, if in doubt, do not use it
but call in professionally qualified personnel. After having verified that the appliance is in good
condition, the protective film may be removed. Carefully clean the external parts of the appliance
with warm water and detergent using a cloth to remove all remaining residues and then dry it with a
soft cloth. If there are still traces of glue residues, remove them by using a suitable solvent (e.g.
