acetone): Under no circumstances must abrasive substances be used. 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, with 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.
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 junction boxes are situated behind the control panel of the top.
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.
In accordance with international rules, 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 EQUIPOTENTIAL system. The connector is situated near
the end of the electric cable inlet and is identified by a label (fig. 10 – pag. 5)
By using a safety thermostat for breakdown tensions there must observe what follows:
-
According to the ruling normative law, the leakage of electric power for these kind of
appliances can have a value of 1 mA without limitations for the maximum for each kW of
installed power. Besides, there must take care that all the switches for breakdown found on
the market have a tolerance for the operating tension of less than the 50%; that’s why there
must be chosen a suitable switch.
-
Connect only a single appliance for each switch
-
In some cases it is possible that the appliance after long periods of inactivity or in case of a
new installation, switches off during working. Most of the times the main reason is the moist
produced during the isolation. The problem can be easily resolved with a short pre-heating
bypassing the safety thermostat.
Connection to the water mains
Connect the water inlet pipe to the mains, following the rules stipulated by the norms in force.
