CONNECTIONS
Gas connection
The appliance is delivered with a threaded cou-
pling. The cylindrical external threading has a
gas thread of “G ½ A”, in accordance with the
EN ISO 228-1:2003 standard. This type of
connection is used in France and some
European countries.
If you use an “R ½” external conic coupling in
accordance with the EN 10226-1:2004 and EN
10226-2:2005 standards or an “Rp ½” internal
cylindrical coupling as per the EN 10226-
1:2004 standard, then unscrew the adapter on
the appliance and either turn it around, or
connect your hose directly to the end of the
tubing.
Screw the gas hose at the end of the appliance tubing, tightening it only by hand. Place
two appropriate tools (one on the tubing to keep it from moving, and the other on the
hose coupling) and tighten the coupling on the hose.
Assemble the hose so that the hose is left hanging in a “U” form.
When the connection is terminated, perform a pressure test to check the sealing of the
appliance. When checking the sealing, make sure not to use washing-up liquid, which
could damage the appliance; instead, use a foam liquid specially intended to detect leaks.
Sealing must be ensured by tightening 2 sealing surfaces beyond the threading with an
appropriate sealing joint between them. To ensure the correct level of sealing along the
threading, a sealing compound or joining compound should be applied to the threading.
If a sealing compound has to be used, we recommend LOCTITE 542.
To locate the gas and electric supply on your appliance, please refer to the dra-
wings on the pages of the description corresponding to the appliance.
For appliances operating with BUTANE / PROPANE gas, use two cylinders with an auto-
matic reversing switch or an outdoor tank, and a standard pressure regulator adapted to
the total flow rate for your model and the gas pressure.
We advise you to use a pressure reducing valve with a minimum of 2 kg./hour for the hobs
and a pressure reducing valve with a minimum of 3 kg./hour for the other models.
As a general rule, an additional safety margin corresponding to 20 – 30% of the applian-
ce’s maximum flow rate must be respected.
To guarantee constant pressure from the gas supply, the pressure regulator should not be
placed more than 2 m from the appliance.
Each appliance must have its own pressure regulator.
