6.2.1.1 Earth connection
!
It is mandatory that the electrical system is equipped with an earth connection.
6.2.2 Connection to the gas network
Before connecting the oven to the gas system, check the oven's requirements relating to the gas

supply. The specifications for the type of setup are shown on the plate (see paragraph 1.13).
The oven is equipped with a cylindrical ½ " GAS threaded pipe in the rear lower part (see figure)
for connection to the gas system.
Check first that the gas distribution system is standard compliant, and in particular that the pipes comply with
the current regulations and laws on building safety. The sections of the fixed pipes in the system must be able
to supply all the appliances in the room, and must be made of rigid steel or copper, and be positioned in view.
It is mandatory to install a manual shut-off cock between each appliance and the gas supply network, in
compliance with current applicable regulations.
It is important to position the cut-off cock in an easy to reach position to make it possible to open or close it
when necessary.
The oven must be connected to the gas supply system using specific fittings and pipes that comply with current
regulations. If using flexible steel pipes, these must be easy to inspect and the length must not exceed 1,5
metre and must not be crimped or be subjected to traction or torsion forces. Be also careful to ensure that the
pipe is not in contact with edges, sharp or hot parts that could damage it, jeopardising operation and safety.
After performing the installation operations, a check must be performed to ensure that there are
!
no gas leaks. This check can be performed using a leak detector spray or non-corrosive foaming
substances.
!
It is strictly forbidden to use open flames to search for gas leaks.
6.2.3 Connection to the chimney and flue
For the evacuation of combustion fumes are provided, even according to the national laws in force in the country
of destination, the following types of installation:
A1: unit without fan and natural draft not designed for connection to an exhaust pipe or to a device for
discharging the products of combustion to the outside of the room in which the appliance is installed. The intake
of combustion air and the evacuation of the combustion products are made in the installation.
B11: unit without fan, with natural draft and break draft device; it is designed to be connected with a pipe to a
chimney / flue which discharges the products of combustion outside the room where the appliance is installed.
The combustion air is drawn directly from the room while the intake of combustion air occurs in the installation.
B21: unit without fan, with natural draft and break draft without device; it is designed to be enslaved under a
hood that discharges the products of combustion outside the room where the appliance is installed. The
combustion air is drawn directly from the room while the intake of combustion air occurs in the installation.
The type of installation depends on the type of gas appliance, from its nominal thermal capacity, the volume of
the room, by the presence of forced ventilation systems and conditions that are nevertheless governed by the
national laws in the field of installation of gas appliances .
