of your appliance.

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

Choose fixed connections or use a flexible pipe in stain-

less 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.

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". Screw the parts without force,

adjust the connection in the necessary direction and

tighten everything.

Rubber pipe holder for liquid gas

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.

If the supply gas pressure is changeable or different from

the necessary pressure, you must fit an applicable pres-

sure adjuster on the gas supply pipe.
