Installation Instructions
This product requires a three-prong grounded outlet.
The installer must perform a ground continuity check
on the power outlet box before beginning the
installation to insure that the outlet box is properly
grounded. If not properly grounded, or if the outlet
box does not meet electrical requirements noted
(under ELECTRICAL REQUIREMENTS), a qualified
electrician should be employed to correct any
deficiencies.
CAUTION: For personal
safety, remove house fuse
or open circuit breaker
before beginning
installation to avoid severe
or fatal shock injury.
CAUTION: For personal safety, the mounting surface
must be capable of supporting the cabinet load, in
addition to the added weight of this 63–85 pound
(28.5–38.5 kg) product, plus additional oven loads of
up to 50 pounds (22.7 kg) or a total weight of
113–135 pounds (51.3–61.2 kg).
CAUTION: For personal safety, this product cannot
be installed in cabinet arrangements such as an island or
a peninsula. It must be mounted to BOTH a top cabinet
AND a wall.
NOTE: For easier installation and personal safety, it is
recommended that two people install this product.
IMPORTANT – PLEASE READ CAREFULLY. FOR
PERSONAL SAFETY, THIS APPLIANCE MUST BE
PROPERLY GROUNDED TO AVOID SEVERE OR
FATAL SHOCK.
The power cord of this
appliance is equipped with a
three-prong (grounding)
plug which mates with a
standard three-prong
(grounding) wall receptacle
to minimize the possibility
of electric shock hazard
from this appliance.
You should have the wall receptacle and circuit checked
by a qualified electrician to make sure the receptacle is
properly grounded.
Where a standard two-prong wall receptacle is
encountered, it is very important to have it replaced
with a properly grounded three-prong wall receptacle,
installed by a qualified electrician.
DO NOT, UNDER ANY CIRCUMSTANCES, CUT,
DEFORM OR REMOVE ANY OF THE PRONGS
FROM THE POWER CORD. DO NOT USE WITH
AN EXTENSION CORD.

ELECTRICAL
REQUIREMENTS
Product rating is 120 volts AC, 60 Hertz, 15 amps and
1.5 kilowatts. This product must be connected to a
supply circuit of the proper voltage and frequency.
Wire size must conform to the requirements of the
National Electrical Code or the prevailing local
code for this kilowatt rating. The power supply
cord and plug should be brought to a separate
15 to 20 ampere branch circuit single grounded
outlet. The outlet box should be located in the
cabinet above the oven. The outlet box and supply
circuit should be installed by a qualified electrician
and conform to the National Electrical Code or the
prevailing local code.
Ensure proper
ground exists
before use

NOTE: Read these next two pages only if you plan to vent your exhaust to the
outside. If you plan to recirculate the air back into the room, proceed to page 6.
OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
NOTE: For back exhaust, care should be taken to align exhaust with space between studs, or wall should be prepared
at the time it is constructed by leaving enough space between the wall studs to accommodate exhaust.
* IMPORTANT: If a rectangular-to-round transition adaptor is used, the bottom corners of the damper
will have to be cut to fit, using the tin snips, in order to allow free movement of the damper.

.
NOTE: If you need to install ducts, note that the total
duct length of 3
1
⁄4” x 10” (8.2 x 25.4 cm) rectangular or
6” (15.2 cm) diameter round duct should not exceed
140 equivalent feet (42.7 m).
Outside ventilation requires a HOOD EXHAUST DUCT.
Read the following carefully.
NOTE: It is important that venting be installed using
the most direct route and with as few elbows as possible.
This ensures clear venting of exhaust and helps prevent
blockages. Also, make sure dampers swing freely and
nothing is blocking the ducts.
Exhaust connection:
The hood exhaust has been designed to mate with
a standard 31⁄4” x 10” (8.2 x 25.4 cm) rectangular duct.
If a round duct is required, a rectangular-to-round
transition adaptor must be used. Do not use less than
a 6” (15.2 cm) diameter duct.
Maximum duct length:
For satisfactory air movement, the total duct length of
31⁄4” x 10” (8.2 x 25.4 cm) rectangular or 6” (15.2 cm)
diameter round duct should not exceed 140 equivalent
feet (42.7 m).
Elbows, transitions, wall and roof caps,
etc.,
present additional resistance to airflow and are
equivalent to a section of straight duct which is longer
than their actual physical size. When calculating the total
duct length, add the equivalent lengths of all transitions
and adaptors plus the length of all straight duct sections.
The chart below shows you how to calculate total
equivalent ductwork length using the approximate feet
of equivalent length of some typical ducts.

contains the kit number for your model.
• This oven is for installation over ranges up to 36“
(91.4 cm) wide.
• If you are going to vent your oven to the outside,
see Hood Exhaust Section for exhaust duct
preparation.
• When installing the oven beneath smooth, flat
cabinets, be careful to follow the instructions on
the top cabinet template for power cord
clearance.

Find the studs, using one of the following
methods:
A. Stud finder – a magnetic device which
locates nails.
OR
B. Use a hammer to tap lightly across the
mounting surface to find a solid sound.
This will indicate a stud location.
After locating the stud(s), find the center by
probing the wall with a small nail to find the edges
of the stud. Then place a mark halfway between
the edges. The center of any adjacent studs should
be 16″ (40.6 cm) or 24″ (61 cm) from this mark.
Draw a line down the center of the studs.
THE OVEN MUST BE CONNECTED TO AT
LEAST ONE WALL STUD.

Remove the box containing the installation
instructions, filters, exhaust adaptor, damper and
the small hardware bag. Do not remove the
Styrofoam protecting the front of the oven.
Fold back all 4 carton flaps fully against carton
sides. Then carefully roll the oven and carton over
onto the top side. The oven should be resting in
the Styrofoam.
