The fitting (fig. 8.6) is made up of:
A - Gas train terminal fitting (rh or lh)
B - Gasket
Before the connection remove the coni-
cal connector C if fitted (fig. 8.4).
D) GAS CONNECTION
Cat: II 2E+3+
The gases used for the operation of
cooking appliances may be grouped by
their characteristics into two types:
- Liquefied gases: Butane Gas (G30)
and Propane Gas (G31)
- Natural Gas (G20 / G25)
Appliances which can be built in
(class 2/1)
For gases supplied by a pipe, the
connection can be made using one of
the following:
•a rigid pipe with screw-nut;
•a metal corrugated flexible hose
according to NF D 36-121 (fig. 8.7a);
•a flexible hose with mechanical ferrule
according to NF D 36-103 or D 36-100
(fig. 8.7b);
For butane-propane distributed by
cylinder or tank, the connection is
made using one of the following:
•a rigid pipe with screw-nut;
•a metal corrugated flexible hose
according to NF D 36-125 (fig. 8.7a);
•a flexible hose with mechanical ferrule
according to XP D 36-112 (fig. 8.7b);
Access must be possible to the full
length of flexible tubes. They must be
replaced before their final date of use
(marked on the hose) and must be a
maximum of 2 m long.
Note: In France, use a tube bearing
the mark NF GAZ.

IMPORTANT:
To fix the gas pipe it is necessary to
operate with 2 spanners (fig. 8.8).
After connecting to the mains, check
that the couplings are correctly
sealed, using soapy solution, but
never a naked flame.
