4. Instruction for the Installer
The side walls of the unit in which the hob is
going to be installed, must not exceed the height
of the working top.
Avoid installing the appliance in the proximity of
inflammable materials (e.g. curtains, tea towels
etc.).
The following instructions about installation and
maintenance must be carried out by qualified
personnel in compliance with the regulation in
force. The regulation to be applied for this type of
installation is NBN D 5I.003 : "Installations
functioning with combustible gas lighter than
air".
The appliance must be electrically disconnected
before all interventions. If any electric supply to
the appliance is required to carry out the work,
ensure all the necessary precautions are
followed.

GAS CONNECTION
It is indispensible that the connection to the gas mains
are carried out by means of an AGB tap. Choose fixed
connections or use a flexible pipe in AGB (stainless
steel).
If using flexible metallic pipes, be careful they do not
come in contact with mobile parts or they are not
squeezed. Use the same attention when the hob is
combinated with an oven.
This hob can be operated by Slochteren gas (G25) with
a nominal pressure of 25 mbar or by natural gas with
nominal pressure of 20 mbar. No regulation is required
for use by these two types of gas.
Before fitting the appliance ensure that the installation
has the correct voltage for the appliance. At full capacity,
the drop in pressure must not exceed 5%. Such a drop
in pressure is caused by the following parameters:
-
maximum capacity of meter;
-
diameter and lenght of the tube in front and behind
the meter;
-
section of transit of variuos tubes positioned on the
circuit;
-
diameter of eventual connections.
IMPORTANT - To ensure a correct operation, a saving
of energy and the long-life of the appliance, the voltage
pressure of the appliance must correspond to the
recommended values.
The adjustable connection is fixed to the comprehensive
ramp by means of a threaded nut GJ 1/2". Interpose the
sealing between the components as shown in fig. 3.
Screw the parts without forcing, adjust the connection in
the required direction and tighten everything.
The adjustable connection allows the feeding pipe to be
situated in the site purposefully allocated on the side of
the protection box of the hob itself (Fig. 4). This connection
allows the overall dimensions of the hob plus the fedding
pipe to be contained into a depth of 30 mm.
IMPORTANT - When the final connection has been
made, it is essential that a thorough leak test is carried
out on the hob and installation. Use some soapy water,
never a flame.
