Test the Installation
Leak testing is to be conducted by the installer ac-
cording 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.
, CAUTION
Never check for leaks with a flame.
Do not continue to the next step until all leaks are
eliminated.
Test for Gas Leaks
Turn on power at breaker.
, CAUTION
If the display flashes and beeps, the polarity of
the wiring may be reversed. Reversed polarity can
damage the range and can result in electrical shock
hazard. Immediately switch off power at the breaker
and return to “Install Electrical Connection”.
Select a rangetop burner knob. Push down and turn
to the flame symbol. If the ignitor/spark module is
operating correctly, it will produce a clicking sound.
Once the air has been purged from the supply lines,
the burner should light within four (4) seconds. After
burner lights, turn knob to the OFF position.
Test each rangetop burner in this fashion.
Call Bosch Service at 800-944-2904 if any of the
burners do not light.
Some yellow streaking is normal during the initial
start-up. Allow unit to operate 4-5 minutes and
reevaluate before making adjustments.
Checking Flame Characteristics
Yellow Flames:
Further adjustment is required.
Yellow Tips on Outer Cones:
Normal for LP Gas.
Soft Blue Flames:
Normal for Natural Gas.
Test Electric Ignition
High Setting
The combustion quality of the flame for each burner
must be visually inspected. For propane, the flame
should be blue with yellow tips. For natural gas, it
should be soft blue in color. The flame should carry over,
or surround, the entire burner and should not lift or
blow off the burner.
To inspect, turn the burner on. See figure on this side for
appropriate flame characteristics.
If the flame is completely or mostly yellow, verify that
the regulator is set for the correct fuel. After adjustment,
retest. If any of the burners continue to burn mostly or
completely yellow, call Bosch Service 800-944-2904.
NOTE: With LP use, some yellow tipping on outer cones
is normal. Low Setting
All burners must also be inspected for carry-over. On
low, the flame should completely surround the burner.
If any of the cooktop burners do not carry over on the
low setting, call Bosch Service 800-944-2904.
Installation is complete at this time.
When properly adjusted:
There should be a flame at each burner port.
There should be no air gap between the flame and
burner.
