ductwork fittings and length are shown in Figure 10, page 9.  
W A R N I N G -F I R E H A Z A R D  
THIS OVEN MUST BE PROPERLY VENTED!  
You may vent your oven in one of three ways. However, do NOT vent into a wall cavity, an attic,  
or an unused area.  
Roof-venting If your oven is located on an outside wall near the roof, as in Figures 7 (31/4" x  
10" duct) and 9 (6" round duct.)  
Wall-venting If your oven is located on an outside wall of your house, as in Figure 6 (31/4" x 10"  
duct) and Figure 9 (6" round duct.)  
Room-venting If your oven is located on an inside wall of your house, as in Figure 8.  
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.

STEP 4: PREPARE THE WALL AND  
UPPER CABINET FOR INSTALLATION  
MEASURE AND TACK / TAPE UP THE  
TEMPLATES  
1. Using a plumb line and (metal) measuring tape, find and  
mark the vertical center line on the back wall, as  
in Figure 18.  
2. Find and mark one or two points where the studs are on  
the wall. (Studs are normally 16 inches apart)  
Then measure and mark the stud locations within the  
mounting plate area on the wall.  
If you cannot find a wall stud, consult a local building  
contractor.  
CAUTION  
DO NOT ATTEMPT TO INSTALL THE MICROWAVE  
OVEN IF YOU CANNOT FIND A WALL STUD.  
NOTE: Be sure the minimum width is 22 inches and the  
distance from the top of the microwave oven to  
the cooking surface is at least 30 inches. See  
Figure 4 on page 4.  
Figure 18  
3. Securely tape or tack the upper cabinet template to the  
upper cabinet. See Figure 22.  
NOTE: If the cabinets are not plumb, adjust the  
mounting plate position to the cabinets.  
Remember, the oven must hang level.  
If the front edge of the cabinet is lower than the  
back edge, adjust the mounting plate position to  
be level with the cabinet front.

5. Measure the bottom of the upper cabinet frame. Trim the  
template so that the template will fit on the bottom of the  
upper cabinet. If the upper cabinet has a recessed  
frame, trim the template so it fits inside the recessed  
area. Align the centerline of the upper cabinet template  
with the centerline of the wall template, then securely  
tape or tack the upper cabinet template in place. See  
Figure 19.

STEP 4: PREPARE THE WALL AND  
UPPER CABINET FOR INSTALLATION  
DRILL THE HOLES IN THE WALL AND UPPER CABINET.  
W A R N I N G  
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 points that  
are over a wall stud. Drill a 3/4" diameter hole at any points over drywall.  
2. Locate the wall stud closest to the center of hole on the mounting plate. Drill 3/16" holes into the wall stud  
in each of the areas. If a wall stud is not located within these areas, drill 3/4" diameter holes nearest to the  
center of the areas as possible.  
If there is not a wall stud within the holed areas or behind points marked A, B, C, and D, DO NOT  
install microwave oven. (Consult building inspector.) There must be at least one stud in those  
areas.  
3. Cut or drill a 2" diameter hole at the marked area, power supply cord hole (M) 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 (not included) to prevent damage to the cord from the rough metal edge.  
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.  
W A R N I N G  
4. Cut out the venting areas (with the saber saw):  
ROOF-VENTED: cut out the shaded area marked E on  
the upper cabinet template.  
WALL-VENTED: cut out the marked area on the wall.  
See Figure 19.  
ROOM-VENTED: Need not make any rectangular hole  
(for ventilation) on the upper cabinet and wall.  
Figure 20  
5. Complete whichever venting system you have chosen.  
Use caulking compound to seal the exterior wall or roof  
opening around the wall cap or roof cap.
