Connect the Range to the Gas Supply
Shut off the main gas supply valve before disconnecting the
old range and leave it off until the new hookup has been
completed. Don’t forget to relight the pilot on other gas
appliances when you turn the gas back on.
Because hard piping restricts movement of the range, the
use of a CSA International-certified flexible metal appliance
connector is recommended unless local codes require a hard-
piped connection.
Never use an old connector when installing a new range.
If the hard piping method is used, you must carefully align
the pipe; the range cannot be moved after the connection is
made.
To prevent gas leaks, put pipe joint compound on, or wrap
pipe thread tape with Teflon* around, all male (external) pipe
threads.
A. Install a manual gas line shut-off valve in the gas line in
an easily accessed location outside of the range. Make
sure everyone operating the range knows where and
how to shut off the gas supply to the range.
B. Install a male ½’’ flare union adapter to the ½’’ NPT
internal thread elbow at inlet of regulator. Use a backup
wrench on the regulator fitting to avoid damage. When
installing the range from the front, remove the 90°
elbow for easier installation.
C. Install male ½’’ or ¾’’ flare union adapter to the NPT
internal thread of the manual shut-off valve, taking care
to backup the shut-off valve to keep it from turning.
D. Connect flexible metal appliance connector to the
adapter on the range. Position the range to permit
connection at the shut-off valve.
E. When all connections have been made, make sure
all range controls are in the off position and turn on
the main gas supply valve. Use a liquid leak detector
at all joints and connections to check for leaks in the
system. Use a product specifically manufactured for
leak detection. Leak testing of the appliance shall
be conducted in accordance to the manufacturer’s
instructions.
nn DO NOT use a flame to check for gas leaks.
When using test pressures greater than ½ psig (3.5 kPa)
to pressure test the gas supply system of the residence,
disconnect the range and individual shut-off valve from
the gas supply piping. When using test pressures of ½ psig
(3.5 kPa) or less to test the gas supply system, simply
isolate the range from the gas supply system by closing the
individual shut-off valve.

shut-off valve (Fig.7-19).
