13.4 Connection to gas
13.4.1 Connection with a rubber hose
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. The inside diameter of the hose must be 8 mm for LIQUID GAS and 13
mm for NATURAL GAS and CITY GAS.
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 tight curves 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).
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.
13.4.2 Connection to natural and city gas

whose specifications comply with the current regulations
(verify that the reference standard is stamped on the hose).
Screw hose connector A onto gas connection B on the
appliance, inserting gasket C in between the two. Slide
rubber hose D onto hose connector A and attach it using
clamp E, in accordance with the legislation in force.
