3.4 Connection to gas
3.4.1 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 or is
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 the 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 beyond its life cycle (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
3.4.2 Connection to natural and town 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

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
on to the hose
connector
A+F
(or

) and to 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
