NOTE: DO NOT install top panel onto double or triple ovens until AFTER stacking the oven cavities. See Part B, Stacking.

B. Stacking

For single ovens, skip ahead to Part C, Restraint Cable Installation.

IMPORTANT

Middleby Marshall STRONGLY RECOMMENDS that PS840 Gas oven cavities be stacked BY AUTHORIZED PERSONEL.

Contact your Middleby Marshall Authorized Service Agent for complete stacking instructions.

1.Stack an oven cavity on top of the lower oven. Check the following:

All four sides of the lower lip (on the bottom edge of the oven cavity) overlap the top of the lower oven

The oven is level

The oven is firmly seated

See Figure 2-9.

2.For triple ovens, repeat Step 1 to install the top oven cavity.

3.Install the top panel using the screws included in the base pad kit, as shown in Figure 2-10.

C. Restraint Cable Installation

Because the oven is equipped with casters, a restraint cable assembly must be installed to limit the movement of the appli- ance without depending on the connector and the quick discon- nect device or its associated piping. One end of the cable is anchored to the eyebolt on the rear surface of the oven’s base pad, while the other is anchored to the wall. See Figure 2-11.

After connecting the restraint cable, move the oven to its final location. Adjust the bottom (hex) sections of the feet so that the casters are off the floor. For quad ovens, lock the two front casters.
