Making the Gas Connection
The appliance should be connected to the mains or to a
gas cylinder in compliance with current directives. Before
making the connection, check that the cooker is regulated
for the gas supply you are using. If not, follow the instruc-
tions indicated in the paragraph “Converting to Different
Types of Gas." On some models the gas supply can be
connected on the left or on the right, as necessary; to
change the connection, reverse the position of the hose
holder with that of the cap and replace the gasket (sup-
plied with the appliance). When using liquid gas from a
cylinder, install a pressure regulator which complies with
the National Regulations.
Important: Check that the supply pressure complies with
the values indicated in table 1 “Burner and Nozzle Char-
acteristics” since this will ensure safe operation, correct
consumption and ensure a longer life for your appliance.
Connection with a Hose
Make the connection using a gas hose that complies with
requirements set forth by the current standards. The in-
ner diameters of the pipe are as follows:
- 8 mm for liquid gas;
- 13 mm for methane.
When installing the hose, remember to take the following
precautions:
•
No part of the hose must come into contact with parts
whose temperature exceeds 50°C;
•
The length of the hose should be less than 1500 mm;
•
The hose should not be subject to twisting or pulling,
and should not have bends or kinks;
•
The hose should not touch objects with sharp edges,
corners or moving parts, and it should not be crushed;
•
The full length of the hose should be easy to inspect in
order to check its condition.
Check that the hose fits firmly into place at the two ends
and fix it with clamps complying with current standards. If
any of the above recommendations can not be followed,
flexible metal pipes should be used. If the cooker is in-
stalled in compliance with the requirements for class 2,
subclass 1, it is highly recommended that the gas con-
nection be made with a flexible metal pipe in compliance
with current safety standards.
Connecting a Flexible, Jointless, Stainless Steel
Pipe to a Threaded Attachment
Remove the hose holder fitted on the appliance. The gas
supply pipe fitting is a threaded 1/2 gas cylindrical male
attachment. Use only pipes and seals that comply with
current National Regulations. The full length of the pipe
when installed must not exceed 2000 mm. After the con-
nection has been made, make sure that the flexible metal
pipe does not come into contact with moveable parts and
that it is not crushed.
Checking the Seal
Important: Once the installation has been completed,
check to make sure that the seals on all the connections
are tight, using a soapy solution (never a flame).
Connecting the Power Supply Cord to the Mains
Install a normalised plug corresponding to the load indi-
cated on the data plate. When connecting the cable di-
rectly to the mains, install an omnipolar circuit-breaker with
a minimum contact opening of 3 mm between the appli-
ance and the mains. The omnipolar circuit breaker should
be sized according to the load and should comply with
current regulations (the earth wire should not be inter-
rupted by the circuit breaker). The supply cable should be
positioned so that it does not reach a temperature of more
than 50°C with respect to the room temperature, along its
length. Before making the connection, check that:
•
The limiter valve and the home system can support
the appliance load (see data plate);
•
The mains are properly earthed in compliance with cur-
rent safety standards and regulations;
•
There is easy access to the socket and omnipolar cir-
cuit breaker, once the hob has been installed.
N.B.: Never use reducers, adaptors or shunts since they
can cause heating or burning.
Converting the Cooker to Different Types of Gas
In order to convert the cooker for use with a type of gas
different than the one for which it was factory set (indi-
cated on the label attached to the lid), the following steps
must be taken:
a) Replace the hose holder mounted on the appliance
with that supplied in the bag of “cooker accessories.”
Important: The hose holder for liquid gas is marked 8,
the hose holder for methane. In any case, always use a
new sealing gasket.
b) Replace the burner nozzles on the hob:
•
Remove the grids and slide the burners from their
housings;
•
Unscrew the nozzles using a 7 mm socket spanner,
and replace them with nozzles for the new type of gas
(see table 1 “Burner and Nozzle Characteristics”).
•
Replace all the components by repeating the steps in
reverse order.
c) Minimum regulation of the hob burners:
•
Turn the tap to minimum;
•
Remove the knob and adjust the regulation screw, which
is positioned in or next to the tap pin, until the flame is
small but steady.
