5.1 Gas connection
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 supplying it
with other types of gas, see chapter “
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.
• Check that the hose is not past its expiry
date (printed on the hose itself).
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 using a hose must be carried
out so that the length of the hose does
not exceed 2 metres when fully
extended for steel hoses and 1.5 metres
for rubber hoses.
• The hoses should not come into contact
with moving parts and should not be
crushed in any way.
