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. Do not 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 a 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 a 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. Turn on the
main gas supply valve and 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 local codes.

Caution: 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.
