B) Connections to the gas supply for:
BE Cat: II 2E+3+
The gas connections are made on the left or on the right (fig. 8.1) at the rear
of the appliance, in such a way that the pipe never passes behind the cooker.
The end of the gas connection, whether on the left or right, that is not being
used, must be closed by attaching a cap fitted with a seal.
* Installation can only be carried out by a qualified technician, and must
conform with the local regulations in force (NBN Standard D 51-003).
* The surfaces next to the cooker must either be made of a heat resistant
material, or must be covered by such a material.
* Ventilation of the room - the combustion of gas can only occur because there
is oxygen present in the air. The air must therefore be able to be renewed,
and the products of combustion must be able to be expelled. The volume of
renewed air must be at least 2m3/h for each kW.
Gases normally used can be grouped into two main families:
- Liquid Gas: Butane Gas (G30);
Propane Gas (G31)
- Natural Gas (G20/G25)
The cooker is supplied ready to operate, using the type of gas which
is indicated on the label attached to it. Sometimes, however, it may be
necessary to change from one gas to another.
Whatever type of gas the cooker is designed for, the following procedures
must be followed:
* Connection to the gas supply.
* Replacement of the burners on the cooking surface.
* Adjustment of the gas flow to the burners on the cooking surface.
Ensure that the cooker is equipped for the type of gas it is to be supplied
with (see label).
The gas supply circuit must conform to the local regulations in force.
