STEP 2: PREPARE THE VENTING SYSTEM

NOTE: The ductwork you need for outside ventilation is not included with your oven. The standard ductwork fittings and length are shown in Figure 9.

WARNING:  FIRE HAZARD

THIS OVEN MUST BE PROPERLY VENTED!

You may vent your oven in one of three ways:

• Roof Venting: If your oven is located on an outside wall near the roof, as in Figure 6 (3-1/4″ x 10″ duct) and Figure 8 (6″ round duct.)
• Wall Venting: If your oven is located on an outside wall on the first floor of your house, as in Figure 5 (3-1/4″ x 10″ duct) and Figure 8 (6″ round duct.)
• Room Venting: If your oven is located on an inside wall of your house, as in Figure 7.

NOTE: If you choose the rear exhaust method (roof or wall venting), be sure there is enough clearance within the wall for the exhaust duct.

REMEMBER AS YOU INSTALL THE VENTING:

• Keep the length of the ductwork and the number of elbows to a minimum to ventilate your oven efficiently.
• Keep the size of the ductwork the same.
• Do not install two elbows together.
• Use duct tape to seal all joints in the duct system.
• Use caulking to seal the exterior wall or roof opening around the cap.

STANDARD FITTINGS

NOTE: If the existing duct is round, you must use a rectangular-to-round adapter, with a rectangular 3″ extension duct installed between the damper assembly and the adapter to prevent the exhaust damper sticking.

DUCT LENGTH

• The total length of the duct system, including straight duct, elbows, transitions, wall or roof caps must not exceed the equivalent of 140 feet.
• For best performance, do not use more than three 90 degree elbows.
• Below are the standard fittings and their equivalent length in feet.

To calculate the equivalent length of each duct piece used, see the examples below

PREPARE THE VENTING BLOWER

STEP 3: PREPARE THE VENTING BLOWER

Your microwave oven is shipped with the blower assembled for room venting (recirculating). You need to adjust the blower if you want wall vented or roof vented installation.

PREPARE THE WALL AND UPPER CABINET FOR INSTALLATION

STEP 4: PREPARE THE WALL AND UPPER CABINET FOR INSTALLATION

MEASURE AND TACK / TAPE UP THE TEMPLATE

1. Using a plumb line and (metal) measuring tape, find and mark the vertical center line (V)on the back wall, as in Figure 22.
2. Find and mark one or two points where the studs are on the wall (Studs are normally 16 inches apart.) and then measure and mark the stud locations. If you cannot find any wall stud, consult a local building contractor.
   • CAUTION: DO NOT ATTEMPT TO INSTALL THE MICROWAVE OVEN IF YOU CANNOT FIND A WALL STUD.
3. Line up the plumb line on the wall with the center line on the mounting plate.
   • NOTE: Be sure the minimum width is 30 inches and the distance from the top of the mounting plate to the range or countertop is at least 30 inches. See Figure 4.
4. Center mounting plate in opening by lining up the plumb line on wall with centerline on mounting plate. Make sure the minimum width is 30 inches and that the top of the mounting plate is located a minimum of 30 inches above the cooking surface. See Figure 23.
   • NOTE: If the front edge of the cabinet is lower than the back edge, adjust the mounting plate to be level with the cabinet front.
5. Measure the bottom of the upper cabinet frame. Trim the edges “A”, “B” and “C” on the upper cabinet template so that the template will fit on the bottom of the upper cabinet. If upper cabinet has a recessed frame, trim template so that it fits inside the recessed area. Align the centerline of the upper cabinet template with the centerline of the mounting plate; then securely tape or tack the upper cabinet template in place. See Figure 23.

DRILL THE HOLES IN THE WALL AND UPPER CABINET

WARNING: BE VERY CAREFUL WHEN DRILLING HOLES INTO THE WALL.

Electrical wires could be concealed behind the wall covering and if the drill hits them you could get an electric shock.

1. Find the points on the mounting plate labeled “A”, “B”, “C” and “D”. Drill a 3/16″ diameter hole at any of these points that are in front of a wall stud. Drill a 3/4″ diameter hole at any of these points that are over drywall.
2. Drill a 3/8″ hole at points “J” and “K” on the upper cabinet template.
   • NOTE: If the bottom of the upper cabinet is recessed 3/4″ or more, you will need 2″x2″ filler blocks (not included) to provide additional support for the bolts. See Figure 24.
   • Mark the center of each filler block and drill a 3/8″ diameter hole at the mark.
   • Align filler blocks over the two openings in the top of the microwave oven cabinet and attach to cabinet with masking tape. See Figure 25.
3. Cut or drill a 2″ diameter hole at the area marked “M”, “power supply cord hole” on the upper cabinet template. If the upper cabinet is metal, you will need to cover the edge of the hole with the power supply cord bushing (supplied) to prevent damage to the cord from the rough metal edge.
   • WARNING: YOU MUST COVER THE EDGE OF THE POWER SUPPLY CORD HOLE IN A METAL CABINET WITH THE POWER SUPPLY CORD BUSHING. FAILURE TO DO SO COULD RESULT IN DAMAGE TO THE CORD AND ELECTRIC SHOCK.
4. Cut out the venting areas (with the saber saw):
   • Roof Venting: cut out the shaded area marked “L” on the upper cabinet template.
   • Wall or Room Venting (Recirculating): go to STEP 5, INSTALL THE MOUNTING PLATE, located.
5. Use caulking compound to seal the exterior wall or roof opening around the wall cap or roof cap.

INSTALL THE MOUNTING PLATE TO THE WALL

STEP 5: INSTALL THE MOUNTING PLATE TO THE WALL

THE OVEN MUST BE CONNECTED TO AT LEAST ONE WALL STUD

1. Draw a vertical line on the wall at the center of the 30″ wide space. Use the mounting plate as the template for the rear wall. Place the mounting plate on the wall, making sure that the tabs are against the bottom of the cabinet. Line up the notch and center line on the mounting plate to the center line on the wall.
2. While holding the mounting plate with one hand, draw circles on the wall at holes “A”, “B”, “C” and “D”. Four holes must be used for mounting. If the holes are not used, the installation will not be secure. Installer must use these holes for proper installation. Use toggle bolts through these holes unless one of them lines up with a stud. Use a wood screw for studs. See Figure 26.
   • NOTE: Draw a fifth circle inside area “E”, through one of the holes to match the location of a stud.
   • For wall vented: The oven requires a rear wallcutout opening for the rear wall duct and the exhaust adaptor must be attached to the mounting plate. See the next page on how to prepare the rear wall cutout opening and the exhaust adaptor/mounting plate for wall vented.
3. Drill holes through the circles. If there is a stud, drill a 3/16″ hole for lag screws. Two or preferably four lag screws at holes “A” and “C”, or “B” and “C” must be used to secure mounting plate to wall. If there is no stud, drill a 3/4″ hole for toggle bolts. Make sure to use at least 1 lag screw at holes of area “E” in a stud, and 4 toggle bolts at holes “A”, “B”, “C” and “D” in the drywall or the plaster.
4. Attach the plate to the wall. To use spring toggle head bolts: Remove the toggle wings from the bolts. Insert the bolts into the mounting plate and replace the spring toggle heads to 3/4″ past the bolt ends. Insert the spring toggle heads into the holes in the wall to mount the bracket. You may pull forward on the bracket to help in tightening the toggle bolts. Tighten all bolts. See Figure 27.

TO PREPARE THE REAR WALL CUTOUT OPENING AND EXHAUST ADAPTOR/MOUNTING PLATE FOR WALL VENTING AND ROOF VENTING:

NOTE: If room vented installation is used, skip this step.

1. Using the Wall-template.This template will give the location and size of the box cutout for the rear wall duct as described in step 5 item 1
2. Using a pencil, put dots through slots “F” and “G”, and through holes “H” and ‘T’. Remove the mounting plate and draw lines extending through the points. This will give the location and size of the box cutout for the rear wall duct. See Figure 28.
   • Attach the exhaust adaptor to the rear mounting plate by sliding it into the guides at the top center of the plate on the wall side. Push in securely until it is past the top locking tabs and in the lower locking tabs. Take care to assure the damper hinge is installed so that it is at the top and that the damper swings freely.
   • Carefully guide the exhaust adaptor, now attached to the mounting plate, into the house duct, before using the screws to attach the plate to the wall. This will assure proper alignment for installation. See Figure 29.
   • Return to step 5, item 3 to continue. After completing the installation of the mounting plate, again check the rear damper for free movement to assure it will operate properly.

ATTACH THE OVEN TO THE WALL

STEP 6: ATTACH THE OVEN TO THE WALL

WARNING: You will need two people to lift this microwave. Failure to use more than one person could result in personal injury.

1. Carefully lift microwave oven and hang it on support tabs (See Figure 26) at the bottom of the mounting plate. Reaching through upper cabinet, thread power supply cord through the power supply cord hole in the bottom of the upper cabinet. See Figure 30.
2. Rotate the microwave oven upward so the top of oven is against the bottom of the upper cabinet or cabinet frame.
3. Then insert a bolt down through each hole in the upper cabinet bottom. See Figure 31. Tighten the bolts until the gap between the upper cabinet and microwave oven is closed.
4. If wall vented or room vented installation is used.
5. Roof vented installation: See Figure 32. Install ductwork through the vent opening in the upper cabinet. Complete the venting system through the roof according to the method needed. See “PREPARE THE VENTING SYSTEM,” STEP 2. Use caulking to seal exterior roof opening around the exhaust cap. See Figure 6.
6. Use power supply cord clamp to bundle the power supply cord. Install the power supply cord clamp, using a screw as shown in Figure 33, to inside of the cabinet.
7. To install the grease filter: Slide it into the slide slot, then push up and toward oven center to lock. See Figure 34.
