Type "B11" gas appliance
These appliances must be connected in one of the following ways:
 Natural evacuation (fig.13-pag.7).
Connection to reliable chimney with natural pull, interposing a pull device, letting out the
products of combustion directly outside.
 Direct forced evacuation (fig.14-pag.7).
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 manaully.
 Forced evacuation under hood (fig.15-pag.7).
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.
Preliminary operations
Remove the appliance from the packaging, ensure that it is intact and, if in doubt, do not use it but
contact professionally qualified personnel. The packaging materials are compliant with environmental
safety regulations. They can be stored without risk, or else should be disposed of in accordance with
current national regulations, particularly those regarding the nylon bag and the polystyrene.
After verifying that the appliance is in good conditions, the protective film may be removed. Clean
the external parts of the appliance carefully 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, these can be
removed using a suitable solvent (e.g. acetone). Under no circumstances should abrasive substances
be used. After the installation the appliance should be levelled by lowering or raising the adjustable
legs.
Gas Connection
Before connecting the appliance, it is necessary to check that the type of gas available corresponds
to the type of gas the appliance has been set for. In the event that they do not correspond, it is
necessary to proceed as described in the paragraph "Functioning with gas different from the
setting". The connection to the threaded coupling, having a diameter of ¾ inch, situated on the
bottom of the appliance, may be fixed or mobile using a compliant rapid pipe fitting. If flexible
piping is used, this must be in stainless steel and compliant with the norm. All the seals on the
junction threads must be in guaranteed materials certified for use with gas. Before the installation of
each single appliance it is necessary to install a cutoff cock for rapid interruption of the gas supply,
placed in an easily accessible position in such a way as to make it possible to turn off the gas supply
when the appliance is not being used. When the connection has been completed, the tightness must
be checked by using a leak-finder spray.
