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.
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. The
appliance is preset for natural gas G20
(2H) at a pressure of 20 mbar. For
supplying it with other types of gas, see
chapter "5.2 Adaptation to different types

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 3 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 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
