20 INSTALLATION
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, the use of a CSA International-certified
flexible metal appliance connector should be
used unless local codes require a hard-piped
connection.
• A manual valve shall 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.
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
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.
NOTE
• Installation must conform with local codes or, in
the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54 or, in
Canada, the Natural Gas and Propane
Installation Code, CSA B149.1.
