GAS CONNECTION
FR
Cat:
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)
The fitting (fig. 8.8) is made up of:
A -
Gas train terminal fitting (rh or lh)
D -
Gasket
Before the connection remove the coni-
cal connector B if fitted (fig. 8.4).
IMPORTANT:
To fix the gas pipe it is necessary to
operate with 2 spanners (fig. 8.10).
After connecting to the mains, check
that the couplings are correctly
sealed, using soapy solution, but
never a naked flame.

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. 8.9a);
•
a flexible hose with mechanical ferrule
according to NF D 36-103 or D 36-100
(fig. 8.9b);
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. 8.9a);
•
a flexible hose with mechanical ferrule
according to XP D 36-112 (fig. 8.9b);
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.
