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 product, plus additional oven loads of up to 50 pounds or a total weight of 113-135 pounds.
• 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 1.70 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.

HOOD EXHAUST

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.

NOTE: If you need to install ducts, note that the total duct length of 31⁄4″ x 10″ rectangular or 6″ diameter round duct should not exceed 140 equivalent feet.
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″ rectangular duct.
If a round duct is required, a rectangular-to-round transition adaptor must be used. Do not use less than a 6″ diameter duct.

Maximum duct length:
For satisfactory air movement, the total duct length of 31⁄4″ x 10″ rectangular or 6″ diameter round duct should not exceed 140 equivalent feet.
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.

DAMAGE – SHIPMENT/INSTALLATION

• If the unit is damaged in shipment, return the unit to the store in which it was bought for repair or replacement.
• If the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
• If the unit is damaged by the installer (if other than the customer), repair or replacement must be made by arrangement between customer and installer.

PARTS INCLUDED

HARDWARE PACKET

You will find the installation hardware contained in a packet with the unit. Check to make sure you have all these parts.
NOTE: Some extra parts are included.

TOOLS YOU WILL NEED

MOUNTING SPACE

NOTES :

• The space between the cabinets must be 30″ wide and free of obstructions.
• If the space between the cabinets is greater than 30″, a Filler Panel Kit may be used to fill in the gap between the oven and the cabinets. Your Owner’s Manual contains the kit number for your model.
• This oven is for installation over ranges up to 36″ 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.
• The depth of the opening cannot be more than 13-1/2″.

PLACEMENT OF THE MOUNTING PLATE

REMOVING THE OVEN FROM THE CARTON/REMOVING THE MOUNTING PLATE

1. 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.
2. 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.
3. Pull the carton up and off the oven.
4. The mounting plate is attached to the back of the oven. Remove the two screws holding it to the oven. The plate will be used as the rear wall template and for mounting the oven to the wall.
5. Set the oven upright. Remove and properly discard plastic bags and Styrofoam.
6. Open the oven door and remove the styrofoam pack from inside the oven. Remove the tape covering the turntable hub.

FINDING THE WALL STUDS

1. Find the studs, using one of the following methods:
   A. Stud finder – a magnetic device which locates nails.
   B. Use a hammer to tap lightly across the mounting surface to find a solid sound. This will indicate a stud location.

2. 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″ or 24″ from this mark.

3. Draw a line down the center of the studs.

THE OVEN MUST BE CONNECTED TO AT LEAST ONE WALL STUD.

DETERMINING WALL PLATE LOCATION UNDER YOUR CABINET

Plate position – beneath recessed bottom cabinet with front overhang

Your cabinets may have decorative trim that interferes with the oven installation. Remove the decorative trim to install the oven properly and to make it level.

THE OVEN MUST BE LEVEL.
Use a level to make sure the cabinet bottom is level.
If the cabinets have a front overhang only, with no back or side frame, install the mounting plate down the same distance as the front overhang depth. This will keep the oven level.

1. Measure the inside depth of the front overhang.
2. Draw a horizontal line on the back wall an equal distance below the cabinet bottom as the inside depth of the front overhang.
3. For this type of installation with front overhang only, align the mounting tabs with this horizontal line, not touching the cabinet bottom as described in Step D.

ALIG NING THE WALL PLATE

CAUTION: Wear gloves to avoid cutting fingers on sharp edges.

1. Draw a vertical line on the wall at the center of the 30″ wide space.

2. Use the mounting plate as the template for the rear wall. Place the mounting plate on the wall, making sure that the tabs are touching the bottom of the cabinet or the level line drawn in Step C for cabinets with front overhang. Line up the notch and center line on the mounting plate to the center line on the wall.

3. While holding the mounting plate with one hand, draw circles on the wall at holes A, B, C and D (see illustration above/actual plate marked with arrows). Four holes must be used for mounting.
   NOTE: Holes C and D are inside area E. If neither
   C nor D is in a stud, find a stud somewhere in area E and draw a fifth circle to line up with the stud. It is important to use at least one wood screw mounted firmly in a stud to support the weight of the oven.
   Set the mounting plate aside.

4. Drill holes on the circles. If there is a stud, drill a 3⁄16″hole for wood screws. For holes that don’t line up with a stud, drill a 5⁄8″ hole for toggle bolts.
   NOTE: DO NOT MOUNT THE PLATE AT THIS TIME.
