CONNECTION (GAS PART)
The nameplates on the gas cook tops state the type of gas to be used with the appliance.
However other types of gas can be used after making a few minor modifications.
(See the instructions in the following paragraph.)
Gas-supply connection
The cook top must be connected to the gas mains or canister in accordance with Standards UNI-CIG7129 and 7131, ensuring
beforehand that it is regulated to suit the gas-supply. If it is not, follow the instructions in the "Adapting to different gas types"
paragraph. If fed by a canister of liquid gas, use pressure regulators that comply with Standards UNI-CIG 7432.
Important: for safe operation, suitable use of energy and longer equipment life, ensure that the feeding pressure is within the
values shown in the table (Burner Technical Details page 6).
Installing the gas-supply coupling
These instructions are for authorised cook top installers in accordance with standards UNI-CIG-7131. Any procedure must be
carried out with the appliance disconnected from the electricity mains.
ATTENTION: the packaging contains two couplings, one cylindrical and one conical; choose the appropriate coupling according
to the country of installation.
Installation sequence:
Fasten the swivel coupling to the gas inlet pipe of the cook top (which has a cylindrical male gas-thread) inserting the seal.
- Tighten the coupling, remembering to point it in the required direction.
Connect the cook top to the gas mains by fitting the seal and fastening the mains pipe to the swivel coupling.

A1= Inlet pipe
A2= Seal
A3= Swivel coupling
A4= Gas-supply flexible or rigid pipe
Only use pipes that comply with Standards UNI-CIG 9891 and seals that comply with UNI-CIG 9264. These pipes must be
installed so that, when fully extended, their length does not exceed 2000 mm. To facilitate installation and to prevent gas leaks,
firstly attach the swivel coupling to the cook top and then to the gas mains pipe. Inverting this sequence may hamper the gas
seal between the pipe and the cook top.
Important: when installation is complete, check that all the couplings are completely sealed by using a soapy solution.
Never use a flame. Also ensure that the flexible pipe cannot come into contact with any moving part of the cook top
(e.g. drawer) and that it is not in a position where it could be damaged.
