A. Top Panel and Base Pad Assembly

1.Install the four leg extensions onto the base pad using the 3/8″-16 × 1″ screws, 3/8″ flat washers, and 3/8″ lockwashers supplied in the Base Pad Kit. See Figure 2-6. Check that the finished sides of each leg

extension face OUTWARDS. One rear leg should be attached using three 3/8″-16 × 1″ screws and the 3/4″ eyebolt, as shown in Figure 2-6. This eyebolt acts as the anchor point for the restraint cable assembly (see Part C, Restraint Cable Installation).

2.If your oven is equipped with the lower shelf, position it in place as shown in Figure 2-6. Check that the lip on the shelf faces DOWN. Seal joint between leg and shelf with NSF listed silicone.

The locking casters should be installed at the FRONT of the oven. The non-locking casters should be installed at the REAR of the oven.

4.Install the lower oven cavity onto the base pad. See Fig 2-7.
