INSTALLATION OF THE UNIT MUST BE DONE BY PERSONNEL
QUALIFIED TO WORK WITH ELECTRICITY AND PLUMBING. IMPROPER
INSTALLATION CAN CAUSE INJURY TO PERSONNEL AND/OR DAMAGE
TO EQUIPMENT. UNIT MUST BE INSTALLED IN ACCORDANCE WITH ALL
APPLICABLE CODES.
The data plate is located above the control panel behind the screen mesh.

specifications are on the data plate. This information should be carefully
read and understood before proceeding with the installation.
The installation of any components such as a vent hood, grease
extractors, fire extinguisher systems, must conform to their applicable

Leg Installation
Legs are available for both the single and double deck installations. Single deck
installations require a 27-inch leg. Double deck installations require 6-inch legs or
casters.
To install the 27-inch legs, place some cardboard on the floor and gently tip the
oven onto its back. Fasten two legs to the oven's front corners using the four 5/16
inch bolts provided in the leg kit. Lift the oven onto its front legs and block the
back up using one of the 27-inch legs set upside down in the center rear of the oven
body. Install the last 27-inch leg onto the oven body on the control side rear.
Gently lift the oven rear, remove the leg set to support the oven center and install it
on the last rear corner.
To install the 6-inch legs or casters, follow the instructions in the Leg Pad section
on the following pages or in the Leg Pad box supplied with the oven.
The adjustable feet on the bottom of each leg may be screwed in or out as
necessary to level the oven.
A torpedo level placed on an oven rack will assist in leveling the oven.
Stacking the Ovens
Remove all the plug buttons from the top of the lower oven.
Remove the stacking kit from the oven compartment of one oven and install the 1
1/4-inch plastic bushing into the top of the lower oven.
Tip the top oven backwards and install two 3/8-inch socket head bolts, found in the
stacking kit, into the two front leg holes that match the holes in the top of the lower
oven. Install the socket head bolts with the heads of the bolt pointing away from
the oven.
Lift the top oven and gently set on top of the lower oven so that the heads of the
socket head bolts nest into the holes in the top of the lower oven.
