Thermador P30 Test Oven Burners, Flame Adjustment if necessary, Burner Test and Adjustment

Step 9: Burner Test and Adjustment

Test Oven Burners

Remove the oven bottom cover. Remove the 4 screws on the sides and the 2 screws on the back, then slide the cover forward while lifting to clear the angled baffle plate mounted to the bottom of the cover.

Test Bake Burner Ignition

Set the oven to BAKE at 350°F. After 30-75 seconds, the burner will ignite. The burner will stay lit until 350°F is reached and then shut off. From this point forward, the burner will cycle on and off to maintain the tem- perature.

Test Broil Burner Ignition

Set cooking mode to BROIL. The burner will ignite after 30-75 seconds.

NOTE: The air shutter for the bake burner is set at the factory for fully-open position under all conditions, and does not require adjustment.

The infrared ceramic broiler does not have an air shutter, so no adjustment is provided.

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 10, and can be adjusted using the following method (unless adjustment is not rec- ommended). 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 10.)

•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 9).

Replace oven bottom cover. Slide cover into place and reattach to bottom of oven cavity.

WARNING

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 remove them!
