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 ½ 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.
Electric connection
Before connecting the appliance, it is necessary to check that the voltage of the power supply
available corresponds to the voltage the appliance has been set for. In the event that they do not
correspond, it is necessary to modify the connection as shown in the electric diagram, if voltage
change is provided for. The terminal blocks are situated behind the instrument board and they can
be removed unscrewing the 2 screws that fix the support and pulling out the same and the terminal
blocks.Furthermore, the efficiency of the earth connection must be checked, and also that the earth
conductor on the connecting side is longer than the other conductors, and that the connecting cable
has a wire bunch adequate for the power absorbed by the appliance and is at least type H05 RN-F.
As in international provisions, before installing the appliance a unipolar device must be
installed with a contacts opening of at least 3mm which must not interrupt the YELLOW-
GREEN earth wire. The device must be installed near the appliance, it must be approved and have
adequate capacity for the absorption of the appliance (see technical features).
The appliance must be connected to the EQUIPOTENZIALE system. The connector is situated near
the end of the electric cable and is identified by a label with the symbol shown on figure 10 (pag. 5).
When using a safety switch for fault currents, the following should be observed:
-
According to current legislation, these kind of appliances can have a leakage current of 1mA
per kW of rated power input with no maximum. It should also be noted that all fault current
