install the oven in accordance with: 1) State and local codes; 2) National Electrical

Vapor Removal from Cooking Equipment

(latest edition), available from National Fire Protection Association, Batterymarch Park, Quincy, MA

02269.

INSTALLING BASIC OVEN

The basic oven must be installed on legs or mounted on a modular stand. Installations on concrete
bases or other supports restricting air circulation underneath the oven is not advisable and may void
the warranty. If using the modular stand, set the oven on the stand after unpacking.

ASSEMBLING THE LEGS TO THE SINGLE OVEN

The legs must be installed on the bottom of the oven. Gently position the oven on its left side, taking
care not to cause scratches or damage.

Attach each of the four leg assemblies to the bottom of the oven with the 24 bolts and lockwashers
(six bolts and lockwashers per leg). Carefully raise the oven to its normal position.

CASTERS

If the oven is to be installed on casters, assemble the
casters to the legs provided. Then attach the caster-leg
units to the oven at each corner using the 24 b olts and
lockwashers. place the locking casters on the front legs
and nonlocking casters on the rear legs. Units on casters
should be tethered to the building using the strain relief
bracket shown in Figure 2.

ASSEMBLING THE STAND TO THE OVEN

Attach each of the four leg assemblies to the bottom of the
oven with the 24 bolts and lockwashers (six per leg).
Carefully raise the oven to the normal position.

Attach the undershelf to the legs with eight bolts and
lockwashers (two per leg).

wiring diagram on the oven and Electrical Data, page 5.

1. Wires to connect both ovens are provided with each oven (X, Y, Z). Carefully route these from
top oven through the bushing (supplied with the stacking kit) through the electrical access
knockout holes common to both ovens. Wires are at least 12 AWG with a 150 degree C rating.

2. Connect wires X, Y and Z from the upper oven to the lower oven per the wiring diagram. Attach the
power supply conduit to the bottom of the lower oven. Connect the power supply leads to the
line side of the terminal block on the bottom oven.

3. Finally, inspect a

nd check all wiring and terminal connections for tightness or pinch points (cover
