Installation
Warning! The following instructions about
installation, connection and maintenance must be
carried out by qualified personnel in compliance with
standards and local regulations in force.
Gas Connection
It is necessary that the connection to the gas mains are
carried out by means of an AGB tap. Choose fixed con-
nections or use a flexible pipe in AGB (stainless steel) in
compliance with the regulation in force. If you use flexible
metallic pipes, be careful they do not come in touch with
mobile parts or they are not squeezed. Also be careful
when the hob is put together with an oven.
The connection must be done according to regulation
NBN D 5I.003.
Important! Make sure that the gas supply pressure of the
appliance obeys the recommended values. The adjustable
connection is fixed to the comprehensive ramp by means
of a threaded nut G 1/2". All the components shown in the
figure have already been assembled in the factory. The
appliance, before leaving the factory, has been tested in
order to give you the best results.

Flexible nonmetal pipes connection:
If it is possible to easily control the connection in its full
area, you can use a flexible pipe. Tightly attach the flexible
pipe by clamps.
Liquid gas: use the rubber pipe holder. Always engage the
gasket. Then continue with the gas connection. The flexi-
ble pipe is prepared for apply when:
– it can not get hot more than room temperature, higher
than 30°C;
– it is no longer than 1500 mm;
– it shows no throttles;
– it is not subject to traction or torsion;
– it does not get in touch with cutting edges or corners;
– it can be easily examined in order to check its condi-
tion.
The control of preservation of the flexible pipe consists in
checking that:
– it does not show cracks, cuts, marks of burnings on the
two ends and on its full length;
– the material is not hardened, but shows its correct
elasticity;
– the fastening clamps are not rusted;
– expired term is not due.
If one or more defects are visible, do not repair the pipe,
but replace it.
Important! When installation is complete, make sure that
the seal of each pipe fitting is correct. Use a soapy
solution, not a flame!
Injectors replacement
1. Remove the pan supports.
2. Remove the caps and crowns of the burner.
3. With a socket spanner 7 remove the injectors and re-
place them with the ones which are necessary for the
type of gas you use (see table in Technical Data sec-
tion).
4. Assemble the parts, follow the same procedure back-
wards.
5. Replace the rating label (it is near the gas supply
pipe) with the one for the new type of gas supply. You
can find this label in the package of the injectors sup-
plied with the appliance.
