Identify the front and rear leg adapters (the front adapters have two threaded inserts, the rear has four). The leg adapters are included

with each specic accessory kit.

Leg to Adapter Installation:

Install the leg’s threaded stud through the hole

in the adapter labeled “C” with the bent ange

of the adapter facing away from the leg.

Screw the 3/4-inch nut supplied in the adapter kit onto the leg stud and tighten. Secure to oven using hardware provided.

Gently tip the oven onto its back. Place the front leg adapter into the front corers of the oven. The

holes without the threaded inserts face the front of the oven and the ange on the adapter points

toward the bottom of the oven.

The edge of the leg adapter with the threaded insert slips under the ange on the oven side, while

the edge without the inserts sits on top of the threaded angle on the oven front.
