Step 5: Installation; Connect Gas Supply - Bosch HGS7022UC/01 Installation Manual

Step 5: Installation - Connect Gas Supply
The gas connection is located below the back panel of
the range (See Figure 4, Page 3), 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 orTeflon _ 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 shut=off valve,
Flexible Connector Method (see Figure 5, 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 shut-off valve.
3. Connect flexible metal appliance connector.
4. Make sure circuit breaker is off and then plug range
cord in to 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 insure that anti-tip
bracket engages and prevents tip-over.
Rigid Pipe Method (see Figure 6, this page)
The configuration of the rigid pipe connection will vary
depending on the location of the gas pipe stub. Refer to
Figure 6 for details.
1. Make sure circuit breaker is off and then plug range
cord in to electrical outlet.
2. 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.
3. Carefully tip range forward to insure 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.
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 shut-off 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 shut-off
valve and tighten connections. Retest for leaks by
turning on the supply line gas shut-off valve. When
leak check is complete (no bubbles appear), test is
complete. Wipe off all detection fluid residue. Proceed
to Step 6: Final Steps.
CAUTION
NEVER CHECK FOR LEAKS WfTH A FLAME.
DO NOT CONTINUE TO THE NEXT STEP UNTfL
ALL LEAKS ARE ELfM[NATED.
CAUTION
Before you plug in an electrical cord, be sure all
controls are in the OFF position.
