27” Leg Installation

With unit in position, fasten the two legs to the front corner pads then to the oven’s front corners
using the four 5/16 inch bolts provided in the leg kit. See leg pad adapter illustration to dermine
differences between front & rear support assemblies.

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 third 27-inch leg onto the oven body on the
control side rear. Gently lift the oven rear, remove the temporary support leg & install it on the last
rear corner.

Leg Installation

Legs are available separately for both the
single and double deck installations. Single
deck installations require a 27-inch leg or
equipment cart. Double deck installations
require 6-inch legs or casters. All these are
available separately.

Place some cardboard on the ground and
with assistance carefully lay the unit on its
back. In stacked

The adjustable feet 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.

Leg Pad Adapter

Identify the front and rear leg adapters (the
front adapters have two threaded inserts, the
rear has four). The leg adapters are included

with each specic accessory kit.

Leg to Adapter Installation:

Install the leg’s threaded stud through the hole

in the adapter labeled “C” with the bent ange

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.
Secure to oven using hardware provided.

Caster to Adapter Installation:

Place the swivel caster against the front leg
pad adapter with the ange 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.

Above: Bottom on unit showing the placement of the leg adapters
and their hole assignment.

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 at washers.

Place the rigid casters against the rear leg

adapter with the ange of the adapter facing

away from the caster.

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 ange on the adapter points

toward the bottom of the oven.

The edge of the leg adapter with the threaded insert slips under the ange 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 at 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 at 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 ange 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 at washers through the holes labeled “E” in the ange

of the oven and into the threaded inserts of the leg adapter.

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.

NOTE: Each unit must have separate electrical connections
