5 Installation
5.1 Gas connection
Gas leakage
Danger of explosion
• After carrying out any operation, check
that the tightening torque of gas
connections is between 10 Nm and
15 Nm.
• Where required, use a pressure
regulator that complies with current
regulations.
• After installation is complete, check for
any leaks with a soapy solution, never
with a flame.
• Installation using a hose must be carried
out so that the length of the hose does
not exceed 2 meters when fully
extended for steel hoses and 1.5 meters
for rubber hoses.
• Hoses should not come into contact with
moving parts and should not be crushed.
General information
Connection to the gas mains can be made
using a continuous wall steel hose in
compliance with the guidelines established
by the standards in force. For use with other
types of gas, see chapter " Adaptation to
various types of gas". The gas inlet
connection is threaded ½" external gas
(ISO 228-1).
Cleaning and maintenance
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.
