Step 6: Test the Installation
1. Test Electric Ignition.
Turn on power at breaker. If LCD screen flashes and beeps
continuously, the wiring is incorrectly installed. Immediately
disconnect power at breaker and return to step 4: CONNECT
RANGE CORD.
Select a rangetop burner knob. Push down and turn to the
flame symbol. If the ignitor/spark module is operating cor-
rectly, 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 (800-944-2904) if any of the burners
do not light.
2. Test/Adjust Flame.
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 14 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 com-
pletely 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 carryover. 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.
