3.5 Connection to gas
3.5.1 Connection with a rubber hose
Installation of the standards-compliant rubber hose must be carried out so that the hose length is no
greater than 1.5 metres. Make sure that the hose does not come into contact with moving parts and is
not squashed. The inside diameter of the hose must be 8 mm for LIQUID GAS and 13 mm for NATURAL
GAS and TOWN 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 and 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 THE GASKET MUST
NOT EXCEED 10NM
3.5.2 Connection to natural and LPG gas

place gasket C in between. Place the rubber tube D on connector A and fix it with
clip E conforming to the regulations in force.
