5.1 Gas connection
(not valid for the
UK)
General information
Connection to the gas supply network can
be made using a continuous wall flexible
steel hose in compliance with the guidelines
established by the standards in force.
For supplying it with other types of gas, see
chapter “5.2 Adaptation to different types
of gas”. The gas inlet connection is
threaded ½” external gas (ISO 228-1).
Connection with a rubber hose
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; replace
it with a new hose.
• 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

to the
appliance’s gas connector
1
(½” thread
ISO 228-1), placing the seal
2
between
them. The hose connector
4
can also be
screwed to the hose connector

,
depending on the diameter of the gas hose
used. After having tightened the hose
connector(s), push the gas hose

onto the
hose connector and secure it with the clamp
For installation in the UK, please

Gas leak
Danger of explosion
• After carrying out any operation, check
that the tightening torque of gas
connections is between 10 Nm and 15
Nm.
• If required, use a pressure regulator that
complies with current regulations.
• At the end of the installation, check for
any leaks with a soapy solution, never
with a flame.
• Installation with flexible hose must be
carried out so that the length of the
piping does not exceed 2 metres when
fully extended as regards flexible steel
hoses and 1.5 metres in case of rubber
hoses.
• The hoses should not come into contact
with moving parts and should not be
crushed in any way.
