Bosch Appliances HDS256U Range User Manual


 
Page 6
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 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
accesible 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.
Step 5: 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 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 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 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.
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 at this time.

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 were 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: Test the Installation
CAUTION
NEVER CHECK FOR LEAKS WITH A FLAME.
DO NOT CONTINUE TO THE NEXT STEP UNTIL ALL LEAKS
ARE ELIMINATED.
CAUTION: Before you plug in an electrical cord, be
sure all controls are in the OFF position.
