The knobs for the gas rings are located on the front part

of the top. The symbols on the knobs have the following

meaning:

• no gas

max. gas

min. gas

Lighting the rings

To obtain the flame more easily, light the

ring before placing a recipient on the grate.

Press the knob corresponding to the ring and turn it

anticlockwise to the “max” symbol.

After lighting the flame, keep the knob pressed for about 5

seconds; this time is necessary for heating the

“thermocouple” (Fig. 1, C) and deactivating the safety valve,

which would otherwise stop the delivery of gas.

Then, make sure the flame is even and turn the knob

to the required setting.

In case of a power failure, bring a flame to the burner

and proceed as already described.

If the flame does not light after several attempts, make

sure the burner “cap” (fig.1, A) is in the correct position.

To turn off the flame, turn the knob clockwise to the symbol

•.

Always lower the flame or turn it off before

removing recipients from the rings.

Watch over your food during cooking with

fats or oils, because these substances can

catch fire when very hot.

Prolonged cooking with potstones,

earthenware pans or cast-iron plates is

inadvisable. Also, do not use aluminium foil

to protect the top during use.

For correct use of the rings

To ensure lower gas consumption and better efficiency,

only use flat bottom recipients of suitable size for the

rings, as given in the table at the foot of the page.

Also, as soon as a liquid starts to boil, lower the flame

enough to keep it on the boil.

DO NOT use scouring pads, steel wool or acids.

Automatic ring lighting is ensured by the presence of a

ceramic igniter plug and a metal electrode (Fig. 1, B).

Carefully clean these parts of the top periodically. Also,

to prevent difficulty in lighting, make sure the burner cap

holes are not clogged.

To remove deposits from the burner cap holes (auxiliary

and semirapid), remove the two fixing screws at the

bottom of the cap and separate the two parts (Fig. 3). After

cleaning, reassemble the two parts and refit them correctly

on the burner.

After washing, refit the top grates, making sure they

are correctly positioned.

C) Adjustable connection

Gas connection

Choose fixed connections or use a flexible pipe in

stainless steel in compliance with the regulation in force.

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.

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 G 1/2". Interpose the

sealing between the components as shown in Fig. 4.

Screw the parts without forcing, adjust the connection in

the required direction and tighten everything.

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.

The appliance is arranged to operate on a 230 V single-

phase power supply. Connection must be made in

compliance with current standards and regulations.

Before carrying out the connection, make sure:

1) the limiter valve and the electrical system can take

the appliance load (refer to the serial no. plate);

2) the supply system is equipped with an efficient

earth connection in compliance with current

standards;

3) the socket or omnipolar switch used are easily

accessible with the appliance installed.

Fit the cable with a plug suitable for the load and connect

it to a suitable safety socket.

To connect directly to the mains, a suitable omnipolar

switch with contact gap of at least 3 mm complying with

current standards must be installed between the

appliance and the network.

The yellow/green earth wire must not be interrupted by

the switch.

The brown phase wire (coming from terminal “L” on the

terminal block) must always be connected to the power

supply phase wire.

In any case the power cable must be positioned in such

a way that no part of it reaches a temperature of more

than 90°C.

An example of an optimum path is given in Fig. 5. The

cable is guided by means of clamps fixed to the side of

the cabinet, in order to avoid any contact with the

equipment beneath the cooktop.

REPLACING THE POWER CABLE

When replacing the power cable only use H05V2V2-F

T90 type cables suitable for the load and operating tem-

perature. Also, the yellow/green earth wire must be

approx. 2 cm longer than the phase and neutral wires

(Fig. 6).

After connection, test the heating elements by operating

them for about 3 minutes.

quickly turning the cock from max. to min.

The above adjustment operations can be easily performed,

whatever the positioning or fixing of the cooktop to the

cabinet.

Replacing nozzles

1. Remove the grates.

2. Remove the burner caps and flame spreaders.

3. Using a 7 mm socket wrench, unscrew and remove

(Fig. 7) the nozzles, replacing them with those required

for the type of gas used (refer to the table on this page).

4. Refit the parts by carrying out the above operations in

reverse order.

5. Then replace the rating plate (located near the gas

connection) with that corresponding to the new type of

gas. The latter is included in the bag of injectors

supplied.

If the pressure of the gas used is different (or variable)

from that provided for, a suitable pressure regulator for

the piped gas (NOT LPG) complying with Standard,

must be installed on the inlet piping.

The use of pressure regulators for liquified gases (LPG)

is allowed provided they comply with Standard.
