INTRODUCTION
Please read these instructions COMPLETELY AND CAREFULLY. They will save you time and
effort and help to ensure optimum oven performance.
Be sure to observe all WARNINGS. These installation instructions are intended for
use by a qualified installer. In addition to these
instructions, the oven shall be installed:
• In the United States, in accordance with the Na­tional Electric Code/State and Municipal codes and/or local codes.
• In Canada, in accordance with Canadian Electric Code C22.1-latest edition/Provincial and Munici­pal codes and/or local codes.
These shall be carefully followed at all times. Note: If installing your oven in Canada please
check to make sure that you have a model with the UL Canadian listing mark, as shown below:
The UL Canadian listing mark consists of the
circled UL symbol preceded by the letter “C,” as shown. This should appear on the ov en’ s rating plate along with the UL United States listing mark, which is the circled UL symbol above but not preceded by the letter “C.”
TOOLS YOU WILL NEED
The following tools are needed to install your new oven:
• Tape measure and straightedge or ruler
• Pencil
• Phillips screwdriver
•Level
• Wire cutters and wire stripper
• 1-inch hole saw
• Hand or saber saw
POWER REQUIREMENTS
The oven must be supplied with the proper volt­age and frequency. The oven is manufactured to be connected to a three-wire or four-wire, single phase, 240 Volt, 60 Hz AC electrical supply on a separate circuit fused on both sides of the line. If a 208 Volt circuit must be used, see Connecting to 208 Volt Circuit, in this manual. A circuit breaker or time­delay fuse sized not to exceed the circuit rating of the appliance specified on the rating plate located on the frame behind the door of the oven is recom­mended.
The oven must be supplied with copper wires ONLY.
It is recommended that you have the electrical wiring and hook-up of your oven performed by a qualified electrician. After installation is complete have the electrician show you where the main dis­connect is and which of the circuit breakers/fuses are for the oven.
CHOOSING OVEN LOCATION
Carefully select the location where the oven will be placed. The oven should be located for conve­nient use in the kitchen, but away from strong drafts. Strong drafts may be caused by open doors or win­dows, or by heating and/or air conditioning vents or fans. Make sure that electrical power can be pro­vided to the location selected.

ELECTRICAL SUPPLY
Before installing the oven have a qualified elec­trician verify that your home is provided with ad­equate electrical service and that the addition of the oven will not overload the branch circuit on which it is to be installed. A separate three-wire or four­wire single phase, 240 Volt, 60 Hz, or a 208 Volt, 60 Hz branch circuit is required.
NOTE: For use with 208 V, 60 Hz supply voltage, see Connecting to 208 Volt Circuit.
For hook-up of the oven you will need to ha ve an approved junction box installed where it will be eas­ily reached through the front of the cabinet where the oven will be located. The o ven has 3 feet of con­duit. Allow two to three feet of slack in the line so that the oven can be moved if servicing is ever nec­essary. DO NOT shorten the flexible conduit.
WIRING REQUIREMENTS
When making the wire connections, use the en­tire length of the conduit provided (3 feet). The con­duit must not be cut.
Before making connections make sure the power is off and read and observe the following:
1. A separate three-wire or four wire, single phase,
240 Volt, 60 Hz or 208 Volt, 60 Hz branch circuit
is required for the oven.
2. The oven must be connected with COPPER
WIRE ONLY.
3. In the United States:
Wiring must conform to the National Electrical
Code, ANSI/NFPA No. 70 latest edition.
You can obtain a copy of the National Electrical
Code by writing:
National Fire Protection Association Batterymarch Park Quincy, MA 02269
