Thermador PD30 Flame Adjustment if necessary, Air Shutter Adjustment if necessary

Step 9: Burner Test and Adjustment

Flame Adjustment (if necessary):

Tube-style gas burners used in Thermador© appli- ances have air shutter systems which are similar to the illustration in Figure 15, and can be adjusted using the following method (unless adjustment 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 carrying over. Adjust the shutter to more-open position if the flame is too yellow. (See Figure 15.)

•Retighten the shutter screw(s).

•After adjustment, reinstall the burner and per- form flame evaluation. The air shutter must fit over the orifice hood for proper operation of the burner.

•Repeat procedure as needed until flame char- acteristics are acceptable. (See Figure 14).
