5 Installation
5.1 Gas connection (not valid for the
UK)
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 using 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 attached to the hose
connector 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).
For installations in the UK, please
refer to the “Local specifications for
UK gas appliances installation”
booklet.
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.
