Connecting the Range to Gas

WARNING
• Isolate the range from the gas supply system by
closing its individual shut-off valve during any
pressure testing of the gas supply system at test
pressures equal to or less than 1/2 psi (3.5 kPa).
• The appliance and its individual shut-off valve
must be disconnected from the gas supply
piping system during any pressure testing of
that system at test pressures in excess of 1/2 psi
(3.5 kPa).
• Shut off the range gas supply valve before
removing the old range and leave it off until the
new hook-up has been completed.
• Because hard piping restricts movement of the
range, a CSA International-certified flexible
metal appliance connector should be used
unless local codes require a hard-piped
connection.
• A manual valve must be installed in an accessible
location in the gas piping external to the
appliance for the purpose of turning on or
shutting off gas to the appliance.
• Never reuse an old connector when installing a
new range.
• To protect against gas leaks, use a qualified pipe
joint sealant on all external threads.
1
Install a male 1/2" or 3/4" flare union adapter
to the NPT internal thread of the manual shut-
off valve, taking care to back-up the shut-off
valve to keep it from turning.
2
Install a male 1/2" flare union adapter to the
1/2" NPT internal thread at the inlet of the
pressure regulator. Use a backup wrench on
the pressure regulator fitting to prevent
damage.
• Check that the gas pressure regulator valve
is in the open position.

NOTE
• The gas pressure regulator valve is open when
shipped. If the range does not work properly
after installation, make sure the regulator valve
is still open.
3
Connect a flexible metal appliance connector
to the adapter on the range. Position the
range to permit connection at the shut-off
valve.
4
When all connections have been made, be
sure all range controls are in the OFF position
and the pressure regulator valve is open
before turning on the main gas supply valve.
• Gas leaks may occur in your system and
create a hazard. Gas leaks may not be
detected by smell alone.
5
Check all gas connection joints and fittings for
leaks with a non-corrosive leak detection fluid,
then wipe off.
• Gas suppliers recommend you purchase
and install a UL approved gas detector.
Install and use in accordance with the
installation instructions.
WARNING
• Do not use a flame to check for gas leaks.
Flexible Connector Hookup
Have the installer show you the location of the
range gas shut-off valve and how to shut it off if
necessary.
