INSTALLATION
DANGER THIS APPLIANCE MUST BE GROUNDED AT THE TERMINAL PROVIDED.
FAILURE TO GROUND THE APPLIANCE COULD RESULT IN
ELECTROCUTION AND DEATH.
WARNING 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.
NOTICE The data plate is located above control panel behind wire mesh screen. The
oven voltage, wattage, serial number, wire size, and clearance
specifications are on the data plate. This information should be carefully
read and understood before proceeding with the installation.
NOTICE The installation of any components such as a vent hood, grease extractors,
fire extinguisher systems, must conform to their applicable National, State
and locally recognized installation standards.
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.

INSTALLATION CONT’D
Leg Pad Adapter
Identify the front and rear leg adapters (the front adapters have two threaded inserts, the
rear has four).
Leg to Adapter Installation:
Install the leg’s threaded stud through the hole in the adapter labeled “C” with the bent
flange 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.
Caster to Adapter Installation:
Place the swivel caster against the front leg adapter with the flange of the adapter facing
away from the caster.
Install the four 5/16 inch bolts through the caster base and the adapter holes labeled “A”
then install the 5/16 inch nuts with washer and lock washers.
Place the rigid casters against the rear leg adapter with the flange of the adapter facing
away from the caster.
Align the caster to the holes in the adapter labeled “B”. NOTE: There are two sets of
“B” holes set at 90°from the each other. One set will create a left rear adapter and the
other set will create a right rear adapter.
Install four 5/16-inch bolts through the caster base and the adapter holes labeled “B” then
install 5/16-inch nuts with lock washers and flat washers.
Adapter to Oven Installation:
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 flange on
the adapter points toward the bottom of the oven.
The edge of the leg adapter with the threaded insert slips under the flange on the oven
side, while the edge without the inserts sits on top of the threaded angle on the oven
front.
Install two 3/8-inch bolts with lock washers and flat washers through the front holes “D”
in the leg adapter and into the threaded inserts on the oven.
Thread one 3/8-inch bolt with lock washer and flat washer into the rear threaded hole
labeled “E” on each of the leg adapters.
The forward threaded hole on the front leg adapter does not get a bolt installed.
Place the rear leg adapters into the rear corners of the oven so that the adapter is under
the flange of the oven side and back. NOTE: If installing a caster place the adapter on
the oven so that the casters roll forward.
Install for 3/8-inch bolts with lock washers and flat washers through the holes labeled
“E” in the flange of the oven and into the threaded inserts of the leg adapter.

INSTALLATION CONT’D
Ventilation and Clearances
Standard minimum clearance from combustible construction is as follows.
4” from side
4” from back
6” from floor
These ovens may be set directly, without legs, on a curbed base or non-combustible
floor.
If the oven is set without legs on a non-combustible floor or a curbed base, maintain a
4-inch back clearance.
If the oven is set directly against a non-combustible back wall, maintain a 6-inch
clearance to the floor.
Do not install the oven closer than 4 inches from another oven on the right hand side
(control panel side).
Do not install the oven closer than 12 inches from an uncontrolled heat source (char
broiler etc.) on the right side.
Keep the appliance area free and clear of combustible material and do not obstruct the
flow of combustion or ventilation air.
The installation of any components such as a vent hood, grease extractors, and/or fire
extinguisher systems, must conform to the there applicable nationally recognized
installation standards.
Electrical Connection
The electrical service entrance is provided by a 1 1/4-inch knockout in the bottom right
front corner of each oven, or at the oven back directly behind the control compartment.
Grounding lugs are provided at both the front and rear service entrances.
The 208/240-volt oven is a dual voltage oven and is shipped from the factory as 208
volt. The oven must be field converted to operate on a 240-volt power supply.
To convert the oven to 240 volt, remove the jumper wire located under the control
compartment behind the bottom trim piece.
With 480-volt installations check to be sure that the motor rotates in a clockwise
direction as viewed from the front of the oven.
To reverse the motor rotation, switch any two incoming power supply leads and
recheck the rotation.
Supply wire size must be large enough to carry the amperage load for the number of
ovens being installed. Wire size information can be found on the oven DATA
PLATE.
This oven can be installed on both single and three-phase supplies and is shipped from
the factory for three-phase.
To phase the oven to match the power supply, follow the charts on the Wiring
Diagram located at the back of the Manual.
