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.

Leg Installation

Legs are available separately for both the single and double deck installations. Single deck installations require a 27inch 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.

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

labeled “B”. NOTE: There are two sets of “B”

holes set at 90° from the each other. One set

Adapter to Oven Installation:

Gently tip the oven onto its left side. 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.
