Above: typical leg and caster installation. Below: accessory options, legs, casters & equipment carts sold

separately. Follow installation instructions with the each specic kit.

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 side, as shown here.

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.

Double-Stack Ovens

To install the 6-inch legs, adj. feet or casters on the lower unit, follow the Leg Pad instructions in the following section or in the instructions included with the leg pads.

Single Oven

To install 27” legs or cart to your unit, place the unit laying on its side (as shown here)

onto a piece of cardborad. Be sure to read

all instructions & follow the instructions provided with the kit.

27” Leg Installation

With unit in position, fasten the two legs to the front left & rear left corner pads then to the oven 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 two legs and block the right side up using one of the 27-inch legs set upside down in the center right side of the oven body. Install the third 27-inch leg onto the oven body on the control side rear. Gently lift the oven to remove the temporary support leg & install it on the last rear corner.

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.

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.

Place the rigid casters against the rear leg

adapter with the ange of the adapter facing

away from the caster. Align the caster to the holes in the adapter

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 Flu Installation

A u extension must be installed on the upper oven of a stacked set.

The extension directs the heat of the lower unit away from the motor of the upper unit. Without this installed, the upper unit can experience problems including premature motor failure.

This extension must be installed.

The ovens may now be set into position.

Be careful if sliding the ovens, they are

not designed to slide over cracks or

obstructions in the oor.
