5 INSTALLATION (for the installation
technician)


 This chapter is intended exclusively for the installation
technician.
None of the operations of this chapter are to be performed by the
user, who is not to carry out any of the operations, measurements or
regulations described below. Therefore any operation performed by
unauthorized personnel will be considered a tampering of the





product itself. Hence unauthorized people carrying out such
procedures will be held responsible for any misfunction, accident or
damage caused by them.
Installation must be executed by qualified personnel in compliance with
local, national and European regulations.
5.1OVEN POSITIONING
Ensure that the oven is put on a flat stand with a suitable carrying capacity.
After unpacking the oven put it in the prepared location, keeping in mind
the minimum distances (see point 4.2). Remove any polystyrene
protections and take off the protecting film (F). Avoid using tools which
might damage the surfaces.
5.2 EQUIPMENT HOOK-UP
5.2.1 Electrical connection
When connecting the appliance to the electric network, an automatic RCD
must be interposed with an opening distance between contacts of at least
3 mm. Connecting the appliance to electrical power just requires plugging
it in.
The electrical outlet must be easily accessible, no moving should be
necessary.




 The electrical connection (plug) must be easily accessible,
also after the oven’s installation.





The distance between the oven and the socket must be appropriate, as
not to cause tension in the power supply cable. The cable, moreover, must
not be located beneath the machine support base.


 If the electrical power supply cable is damaged, it must be
replaced by the technical assistance service or by a qualified
technician to prevent any risks.
5.2.1.1 Ground connection


 It is compulsory that the electrical system is equipped with a
ground connection.
The appliance must be part of an equipotential system whose
effectiveness must comply with current regulations. The connection is
done on the terminal marked with the symbol which you will find near the
black cable clamp. The section of the equipotential wire must be at least
10mm

. Theequipotential symbol is showed below:
5.2.2 Gas connection


 Before connecting the oven to the gas line, please check the oven
gas-supply requirements and the specifications regarding the presetting
type on the specific label (see point 1.13).
The oven is provided in its lower part (see picture) with a gas tube with a
½" cylindrical thread to connect to the gas system.





First of all check that the gas distribution system and especially the gas
tubes comply with the rules and regulations on building safety. The
system’s stationary tubes must have sections big enough to be able to
supply all the machines in the building, they must be visible and made of
rigid steel or copper.
It is compulsory to install a manual cutoff cock between every machine
and the gas feeding line, according to current rules and regulations.
It is very important that the cutoff cock is easily accessible so as to be able
to turn it off and on when needed.
The oven connection to the gas feeding line must be performed through
specific pipe fittings and pipes, in compliance with the rules in force. In
case flexible steel pipes are used, they must be easy to check, they must
not be longer than 1 metre and they must not have chokes, be strained or
twisted. Pay extra attention so that the pipe does not get in contact with
sharp edges and hot parts, which might damage it, jeopardizing its
functionality and safety.


 After the installation a control is called for, to make sure that there are
no gas leaks. The control can be performed using specific gas leak sprays
or non-corrosive foams.


 It is absolutelyforbidden to use flames to look for gas leaks.
5.2.3
Vent stack connection and exhaust fumes
elimination
According to the laws in force in the Country where the oven is
installed, the following installations are foreseen for the elimination of
the exhaust fumes:
A1: Natural draught appliance without break-drought anti-wind device
and with no connection necessity of flue for the combustion product
exhaust outside the place where the appliance is installed.





B11: natural draught equipment with anti-wind draught-breaking
device connected to the flue, for the exhaust fumes to be let out from
the room where the oven is installed.
B21: natural draught equipment without anti-wind draught-breaking
device, for the exhaust fumes to be let out from the room where the
oven is installed. A direct connection with outbound pipes is not called
for, yet the equipment must be put under an effective motorized hood.
