8B. 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 13 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.
