The gas connection is located below the back panel of
the range (See Figure 4, Page 4). It is accessible
through the warming drawer access panel or from the
back of the range. To reach access panel, remove
warming drawer.
Shut off main gas supply valve before disconnecting the
old range and leave it off until the new hook-up has
been completed. Don’t forget to relight the pilot on
other gas appliances when you turn the gas back
on.
The range can be installed using rigid pipe or a CSA
International-certified flexible metal appliance connector.
If using a flexible connector, always use a new
connector.
Apply pipe joint compound or Teflon** tape appropriate
for use with LP gas and Natural gas around all male pipe
threads to prevent leaks.
If not already present, install gas shut off valve in an
easily accessible location. Make sure all users know
where and how to shut off the gas supply to the range.
Note: The installer should inform the consumer of
the location of the gas shutoff valve.
Step 7: Installation - Connect Gas Supply
Flexible Connector Method (see Figure 11, this page)
1. Install male 1/2” flare adaptor at the 1/2” NPT
internal thread of the range inlet. Use a backup
wrench on the elbow fitting to avoid damage.
2. Install male 1/2” or 3/4” flare union adapter on the
NPT internal thread of the manual shutoff valve.
3. Connect flexible metal appliance connector.
4. Make sure circuit breaker is off and then plug range
cord into electrical outlet.
5. Push range back into position insuring that range leg
slides under the anti-tip bracket. The range will sit
3/4” away from the wall when properly installed.
Note: Be careful not to crimp flexible connector!
6. Carefully tip range forward to ensure that anti-tip
bracket engages and prevents tip-over.
Important note for LP users: The range is
shipped from the factory for use with natural gas.
For use with propane (LP) gas, your range must first
be converted using the LP conversion kit.

Proceed to “Test for Gas Leaks”, next column.
Test for Gas Leaks
Leak testing is to be conducted by the installer according
to the instructions given in this section.
Turn on Gas. Apply a non-corrosive leak detection fluid
to all joints and fittings in the gas connection between
the shutoff valve and the range. Include gas fittings and
joints in the range if connections may have been
disturbed during installation. Bubbles appearing
around fittings and connections indicate a leak.
If a leak appears, turn off supply line gas shutoff valve
and tighten connections. Retest for leaks by turning on
the supply line gas shutoff valve. When leak check is
complete (no bubbles appear), test is complete. Wipe
off all detection fluid residue. Proceed to Steps 8A and
8B: Final Steps.

Rigid Pipe Method (see Figure 12, this page)
The configuration of the rigid pipe connection will vary
depending on the location of the gas pipe stub. Refer to
Figure 12 for details.
1. Make sure circuit breaker is off and then plug range
cord into electrical outlet.
2. Push range back into position ensuring that range
leg slides under the anti-tip bracket. The range will
sit 3/4” away from the wall when properly installed.
3. Carefully tip range forward to ensure that anti-tip
bracket engages and prevents tip-over.
4. Connect pipe to range at union. Access the
connection through the access panel behind the
warming drawer.
Note: Be careful not to apply pressure to warming
drawer element during rigid pipe installation.
Before you plug in an electrical cord, be sure all
controls are in the OFF position.
CAUTION
NEVER CHECK FOR LEAKS WITH A FLAME.
DO NOT CONTINUE TO THE NEXT STEP UNTIL ALL
LEAKS ARE ELIMINATED.
