11.3.1 Connection with a rubber hose
WARNING: 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 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: verify that the hose is not past its expiry date
(serigraphed on the hose itself).
Make the connection to the gas mains using a rubber
hose whose specifications comply with current
standards (verify that the reference standard is
stamped on the hose).
Carefully screw the hose connector 3 to the
appliance’s gas connector 1 (1/2” thread ISO 228-1),
placing the seal 2 between them. The hose connector
4 can also be screwed to the hose connector 3,
depending on the diameter of the gas hose used. After having tightened the
hose connector(s), push the gas hose 6 onto the hose connector and secure it
with the clamp 5 that is compliant with the applicable standard.
