 The Fire Brigade rules
Fumes evacuation
These appliances are Type "A1" and it is not necessary to connect them 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. If
this is not possible, the use of an extractor fan connected directly to the external environment with a
capacity no lower than what is stated in table 1 is acceptable. This value must be increased by the
air exchange necessary for the well-being of the operators, in accordance with the norms in force.

INSTALLATION
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 cut off 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.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the available power
supply corresponds to the voltage the appliance has been set for. If they do not correspond, it is
necessary to modify the connection as shown in the electric diagram, if voltage change is provided
for. The junction boxes are situated behind the control panel can be accessed by loosening the two
screws holding the panel itself. If the supply cord is damaged, it must be replaced by the service
agent or similarly qualified persons in order to avoid a hazard.
