INSTALLATION

UNPACKING

Immediately after unpacking the oven, check for possible shipping damage. If this oven is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, verify that the electrical service agrees with the specifications on the oven data plate, located

inside of the bottom front cover.

Do not use the doors or their handles to lift the oven.

LOCATION

The installation location must allow adequate clearances for servicing and proper operation.

INSTALLATION CODES AND STANDARDS

Hobart ovens must be installed in accordance with:

In the United States

1. State and local codes.

2. ANSI/NFPA 96, "Vapor Removal from Cooking Equipment" (latest edition), available from National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

3. National Electrical Code, ANSI/NFPA-70 (latest edition).

In Canada

1. Local Codes

2. Canadian Electrical Code, CSA Standard C22.2 No. 3 (latest edition) “Electrical Features of Fuel Burning Equipment.”

INSTALLING BASIC OVEN

The basic oven must be installed on legs or be 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 Oven

2. Position oven on its back, taking care not to scratch or damage it.

3. Attach each of the 4 leg assemblies to bottom of oven with 24 bolts and lockwashers (furnished) (6 per leg). Carefully raise oven to its normal position.

Assembling Cabinet Base or Stand

1. Screw two locating studs (found in cabinet base or stand carton) through the cabinet top flange or the stand base bottom into bottom of oven (Fig. 1).

2. Attach each of the 4 leg assemblies to bottom of stand with 24 bolts and lockwashers (furnished) (6 per leg).

CASTERS

If the oven is to be installed on casters, assemble the casters to the legs provided. Place the locking casters on the front legs and non-locking casters on the rear legs.

ASSEMBLING STACKED OVENS

1. Unpack the ovens and stack kit. Position one oven on its back for access to the oven bottom, taking care not to scratch or damage it. Attach the 4 leg assemblies with the 24 bolts and lockwashers (furnished) (6 per leg).

2. Place lower oven (with legs) on floor and remove two 7/16" (11.1mm) diameter knockouts on each side of top cover plus the 13/8" (35mm) diameter knockout at the right front of the top cover.

Install the two locating studs (included in leg stack set) into screw plates on underside of upper oven (Fig. 2).

4. Remove oven chimneys stored at the rear of both ovens. Discard one chimney. Attach the remaining chimney to the top of the upper oven (oven without legs) (Fig. 3). The flanges on the chimney are to be positioned under the top cover.

5. Move the oven with legs to the installed position and place the upper oven on top of the lower oven using the locating studs. Remove the wiring compartment cover from the front of both ovens. This will facilitate routing the power leads (furnished) to the top oven, as well as attaching the 1" (25.4mm) conduit nipple and locknut (furnished).

6. Attach the short flue extension over the exhaust vent at the rear of the upper oven. Slide the long flue extension tube over the exhaust vent at the rear of the lower oven (Fig. 3). These extensions should direct the exhaust fumes upward through and above the top oven.

7. Place the 1" (25.4mm) conduit nipple through the 13/8" (35mm) hole in the bottom of the top oven and the top of the bottom oven and clamp the two ovens together with the locknut from the underside.
