Burner adjustments must be performed by a
qualified technician. Improper adjustments
may cause harmful by-products or void the
appliance’s warranty.
Allow burners to cool before attempting to re
-
move them!
WARNING
Step 7: Burner Test and Adjustment
Flame Adjustment (if necessary):
Tube-style gas burners used in Thermador©
appliances have air shutter systems which are
similar to the illustration in Figure 14, and can be
adjusted using the following method (unless ad
-
justment is not recommended). It is necessary to
remove the burner from the appliance in order to
perform air-shutter adjustments.
• Loosen shutter screw(s) and turn shutter to
new position.
• Adjust the shutter to more-closed position if
the flame is lifting or blowing, or is not carry-
ing over.
• Adjust the shutter to more-open position if
the flame is too yellow. (See Figure 14.)
• Retighten the shutter screw(s).
• After adjustment, reinstall the burner and
perform flame evaluation. The air shutter
must fit over the orifice hood for proper opera
-
tion of the burner.
• Repeat procedure as needed until flame char
-
acteristics are acceptable. (See Figure 13.)
Call Thermador® if:
1. Any of the burners do not light.
2. Any of the burners continue to burn
yellow.
