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.

Installer: Inform the consumer of the location of the gas

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