IV. ASSEMBLY

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 exten- sion 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.

3.Install one caster onto each leg extension, as shown in Figure 2-7. Use the 3/8″-16 × 1″ screws, 3/8″ flat wash- ers, and 3/8″ lockwashers supplied in the Installation Kit. 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.

5.For single ovens ONLY:

Install the top panel using the screws included in the base pad kit, as shown in Figure 2-8. Then, skip ahead to Part

For double or triple ovens:

Continue on to Part B, Stacking. Note that the top panel should NOT be installed for double and triple ovens until after stacking the oven cavities.
