CFM Corporation 7000 - Manual (Page 21)

DANGER: EXPLOSIVE AND FLAMMABLE!
If the appliance is for connection to
natural gas, the gas connections should
be made by a qualified installer or a
licensed plumber. The gas-supply line
must not be installed by the consumer.
The valve-orifices and fuel supply hose sys-
tem necessary for use with natural gas is differ-
ent than the system required for L.P. gas.
Modification to the burner valve/orifices allow
the use of natural gas. An L.P. cylinder is not
needed.
WARNING: Do not use liquid propane
(L.P.) gas in an appliance designed for nat-
ural gas. Use only natural gas in an appli-
ance designed for natural gas.
INSTALLATION FOR NATURAL GAS
The maximum inlet supply pressure is 11.0"
w.c. for propane gas and 7.0" w.c. for natural
gas.
The specified supply pressure is 11.0" w.c. for
propane gas and 7.0" wc. for natural gas.
The piping system should be installed by a
qualified service technician in accordance with
the National Fuel Gas Code (NFPA 54/ANSI
Z223.1) in the U.S.A., including:
1. The appliance and its individual shut-off
valve must be disconnected from the gas-sup-
ply piping system during any pressure testing
of that system at test pressures in excess of
1/2 psi (3.5 kPa).
2. The appliance must be isolated from the
gas-supply piping system by closing its individ-
ual manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psi (3.5
kPa).
A quick-connect coupling sleeve with 3/8” female
end is provided. Install the connector socket at
the pipe end, after the shut-off valve. This must
be installed where the grill will be in use.
It is important to observe the safety guidelines
for choosing a safe location. The gas supply must
be shut off prior to installation of the quick con-
nector socket. Use only a matching factory
authorized quick-connect plug with the quick-con-
nect socket.
Natural-gas units are equipped with a 12-foot-
long quick-connect fuel hose in place of the short-
er hose/regulator attached to the burner valve.
Prior to inserting, turn on gas supply and test all
connections with an ammonia-free soap and
water solution. Apply this solution to the stem of
the shut-off valve and opening of the socket to
detect leaks. (See Leak Testing Natural Gas
Connections later in this section).
