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

6. Place cooktop right side up into the cutout.

NOTE: Make sure that the front edge of the cooktop is 
parallel to the front edge of the countertop. If repositioning is 
needed, lift entire cooktop up from the cutout to avoid 
scratching the countertop.

7. Connect blower exhaust scroll to ducting.

8. Use vent clamps to secure the ducting to the blower exhaust 

scroll.

9. Reinstall grease filter.

10. Reinstall vent grille.

IMPORTANT: The following additional steps must be performed 
if the product is being installed in peninsula or island cabinetry.

The blower exhaust scroll is shipped from the factory set to 
exhaust straight out the back of the cabinet through an exterior 
wall.

1. Remove the right and left grates. Then remove the vent grille. 

See illustration in Step 4 of the “Install Cooktop” section.

2. Locate the 4 locknuts inside the plenum.

3. Use 

³⁄₈" socket and ratchet handle to loosen the nut half of a 

rotation. Repeat this process for each of the 4 nuts.

4. With the nuts loosened, the blower exhaust scroll can be 

easily rotated downward.

5. Retighten each nut with the 

³⁄₈" socket, extension and ratchet.

1. Apply pipe-joint compound made for use with Natural and LP 

gas to the smaller thread ends of the flexible connector 
adapters (see C and G in the following illustration). 

2. Attach one adapter to the gas pressure regulator and the 

other adapter to the gas shutoff valve. Tighten both adapters.

3. Use a 

¹⁵⁄₁₆" combination wrench and channel lock pliers to 

attach the flexible connector to the adapters. Check that 
connector is not kinked.
