Instructions for the installer
11.3 Gas connection
At the end of the installation, check for any leaks with a soapy solution, never with a flame.
The tightening torque between connections that incorporate a gasket must be between 10 and 15 Nm.
After carrying out any operation on the appliance, check that the gas connections are properly tightened.
If the appliance is fuelled by LPG, use a standards-compliant pressure regulator
and connect to the gas cylinder in accordance with the standards in force.
Make sure that the feed pressure complies with the values indicated in the table
“12.3 Burner and nozzle characteristics table”.
11.3.1Connection with a rubber hose
CAUTION: The following instructions are valid solely for Class 1 installations. See fig. C in
chapter “11.1 Installing in kitchen units”.
Connection using a rubber hose complying with current standards is only permitted if the hose can be
inspected along its entire length.
The inside diameter of the hose must be 8 mm for LPG GAS and 13 mm for NATURAL GAS and CITY
GAS.
Installation with a standards-compliant rubber hose must be carried out so that the
length of the piping does not exceed 1.5 metres; make sure that the hose does not
come into contact with moving parts and that it is not crushed in any way.
Verify that all the following conditions are met:
• the hose is fixed to the hose connection with safety clamps;
• no part of the hose is in contact with hot walls (max. 50°C);
• the hose is not under traction or tension and has no kinks or twists;
• the hose is not in contact with sharp objects or sharp corners;
• if the hose is not perfectly airtight and leaks gas,
do not try to repair it
: replace
it with a new hose;
• verify that the hose is not past its expiry date (serigraphed on the hose itself).
