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.

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

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.

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.

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.

INSTALLATION continued

Ventilation and Clearances

Standard minimum clearance from combustible construction is as follows.

4” from side

4” from back

6” from oor

• These ovens may be set directly, without legs, on a curbed base or non-combustible oor.

• If the oven is set without legs on a non-combustible oor 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

oor.

• 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 area free & clear of combustible material, and do not obstruct the ow of combustion or

ventilation air.

• The installation of any components such as a vent hood, grease extractors, and/or re extinguisher

systems, must conform to the applicable nationally recognized installation standards.

NOTICE The installation of any components such as a vent hood, grease

extractors,reextinguishersystems,mustconformtotheir applicable National, State and locally recognized installation standards.

WARNING

Electrical Connection

The electrical connection must be made in accordance with local codes or in the absence of local codes with NFPA No.70, latest edition (in Canada use: CAS STD. C22.1).

The electrical service entrance is provided by a cord and plug located at the oven back directly behind the control compartment.

Each oven requires a 115-volt grounded supply and 7.1 amps.

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 APPLIANCE IS EQUIPPED WITH A 3-PRONG (GROUNDING) PLUG FOR YOUR PROTECTION AGAINST SHOCK HAZARD AND MUST BE PLUGGED DIRECTLY INTO A PROPERLY GROUNDED 3-PRONG RECEPTACLE. DO NOT CUT OR REMOVE THIS GROUNDING PRONG FROM THE PLUG.
