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 Na-
tional Electric Code/State and Municipal codes
and/or local codes.
• In Canada, in accordance with Canadian Electric
Code C22.1-latest edition/Provincial and Munici-
pal 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 oven'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 volt-
age 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 time-
delay 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 recom-
mended.
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 dis-
connect 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 conve-
nient use in the kitchen, but away from strong drafts.
Strong drafts may be caused by open doors or win-
dows, or by heating and/or air conditioning vents or
fans. Make sure that electrical power can be pro-
vided to the location selected.
