operators, in accordance with the norms in force. (approximately a total of 35 m /h per KW of gas
output installed).
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.
acetone): For no reason use abrasive substances. After having been put into place, the appliance
must be levelled by regulating the adjustable feet.
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. 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 11 (pag.5).
