KitchenAid 30-Inch, 4-Burner Downdraft Cooktop Installation Guide

After verifying the proper burner operation, turn the control knobs 
to “OFF.”

■

Turn surface burner control knob to the “OFF” position. 

■

Check that the power supply cord is plugged in and the 
circuit breaker has not tripped or the fuse blown. 

■

Check that the gas shutoff valves are set to the “open” 
position. 

■

Check that burner caps are properly positioned on burner 
bases.

Recheck operation of surface burners. If a burner does not light 
at this point, contact your dealer or authorized service company 
for assistance.

This cooktop is equipped with a Smart Port Burner System. The 
Smart Port Burner System produces a small flame directly under 
each grate finger and a larger flame between each grate finger. 
The visual difference between the ports will be noticeable when 
the burner is used or when adjustments are made to the flame 
length. 

Adjust the height of top burner flames. The cooktop “low” burner 
flame should be a steady blue flame approximately ¼" (0.64 cm) 
high.

The flame can be adjusted using the adjustment screw in the 
center of the valve stem. The valve stem is located directly 
underneath the control knob.

1. Light 1 burner and turn to lowest setting.

2. Remove the control knob.

3. Hold the knob stem in the low position using a pair of pliers. 

Use an

 ¹⁄₈" (3.0 mm) flat-blade screwdriver to turn the screw 

located in the center of the control knob stem until the flame 
is the proper size.

4. Replace the control knob.

5. Test the flame by turning the control from “LO” to “HI,” 

checking the flame at each setting.

6. Repeat the above steps for each burner.

1. Check that all parts are now installed. If there is an extra part, 

go back through the steps to see which step was skipped.

2. Check that you have all your tools.

3. Dispose of/recycle all packaging materials.

4. Use a mild solution of liquid household cleaner and warm 

water to clean cooktop before use. Dry thoroughly with a soft 
cloth. For more information, see the “Cooktop Care” section 
of the Use and Care Guide.

5. Read “Cooktop Use” in the cooktop Use and Care Guide.

6. Reconnect power.

NOTE: If the cooktop does not work after turning on the power, 
check that a circuit breaker has not tripped or a household fuse 
has not blown. See “Troubleshooting” section in the Use and 
Care Guide for further information.

7. Use the Flow Tester Card provided with your cooktop to 

check the airflow (see card for step-by-step instructions).

Please reference the “Assistance or Service” section of the Use 
and Care Guide or contact the dealer from whom you purchased 
your cooktop.
