PLEASE KEEP THIS MANUAL FOR FUTURE USE
GENERAL
Hobart ovens are produced with quality workmanship and material. Proper installation, usage, and
maintenance of your oven will result in many years of satisfactory performance.
It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions
provided.
INSTALLATION
Before installing, verify that the electrical service agrees with the specifications on the rating plate
located on the right front side panel. If the supply and equipment requirements do not agree, do not
proceed with the installation. Contact your Hobart service representative immediately.
UNPACKING
This oven was inspected before leaving the factory. The transportation company assumes full
responsibility for safe delivery upon acceptance of the shipment. Immediately after unpacking, check
for possible shipping damage. If the oven is found to be damaged, save the packaging material and
contact the carrier within 15 days of delivery.
1. Tilt the oven on its back side.
2. Place the oven on a four-wheel dolly.
3. Move oven to its installation position.
4. Remove oven from the dolly and place on two pieces of 2 x 4 wood.
5. Carefully unpack oven.
Do not use the door or handle to lift oven.
LOCATION
When the crate is turned on its side, the oven will pass through a 34" (86 cm) door opening (or 30"
[76 cm] opening without the crate). Verify that the doors and access routes into the kitchen area will
permit clearance.

When installed, minimum clearance from combustible and non-combustible construction must be
2.5" (63.5 mm) at the sides and 2.5" (63.5 mm) at the rear.
The installation location must allow adequate clearances for servicing and proper operation.
A minimum front clearance of 36" (914.4 mm) is required.
Information on the construction and installation of ventilating hoods may be obtained from the
standard for "Vapor Removal from Cooking Equipment," NFPA No. 96 (latest edition), available from
the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
Exhaust: Approximately 2000 CFM required for double stacked ovens.
Approximately 1500 CFM required for single oven.
Make-up air should be 65% to 80% of the exhaust air rating.

In the United States of America:
1. State and local codes.
2. National Electrical Code, ANSI/NFPA-70 (latest edition). Copies may be obtained from The
