CONNECTION USING RUBBER HOSES COMPLYING WITH THE CURRENT REGULATIONS IS
ONLY PERMITTED IF THE HOSE CAN BE INSPECTED ALONG ITS ENTIRE LENGTH.
THE TIGHTENING TORQUE BETWEEN CONNECTIONS THAT INCORPORATE A GASKET MUST
NOT EXCEED 10NM
3.4.2 Connection to natural and city gas
Make the connection to the gas mains using a rubber hose whose specifications
comply with the current regulations (verify that the reference standard is stamped
on the hose).
Screw the hose connector A to the gas connector B of the appliance, placing the
seal C between them. Push the rubber hose D onto the hose connector A and
secure it with the clamp E that is compliant with the current standard.
3.4.3 Connection to liquid gas
Use a standards-compliant pressure regulator and carry out the connection to the gas cylinder in
accordance with the regulations in force.
Make sure that the supply pressure complies with the values indicated in the paragraph "3.2/3.3 Burner
and nozzle characteristics table".
Screw the small hose connector F onto the large hose connector A; connect
the block that this makes to the gas connector B (or use the hose connector
G which must be connected directly to the gas connector B) and place the
seal C in between them. Push the end of the rubber hose H onto the hose
connector A+F (or G) and onto the outlet connection of the pressure
reducer on the gas cylinder. Secure the end of the hose H to the hose
connector A+F (or G) with the standards-compliant clamp I.
The hose connector G illustrated is not supplied with the appliance. Only use standards-compliant hose
connectors.
3.4.4 Connection with a flexible steel hose (for all types of gas)
This type of connection can be made on both built-in and free-standing
appliances. Only use standards-compliant steel hoses whose length is no
greater than 2 metres. Screw the end of the flexible hose L onto threaded ½"
external gas connector B with the seal C positioned between the two (ISO
228-1).
At the end of the installation, check for any leaks with a soapy solution,
never with a flame.
For the connection between the cooker and the gas cylinder use a piece of standards-compliant hose no
less than 1.4 m in length.
