Mark Rear Wall

The microwave oven must be installed on a minimum of 1 wall 
stud, preferably 2, using a minimum of 1 lag screw, preferably 2.
1. Using measuring tape, find and clearly mark the vertical 

centerline of the opening.

A. Centerline

2. Align the centerline of the wall template with the centerline on 

the wall, making sure it is level, and that the top of the wall 
template abuts the bottom edge of the upper cabinet. Tape 
the wall template into place.

NOTES:

If the front edge of the upper cabinet is lower than the back 
edge, lower the wall template so that its top is level with the 
front edge of the cabinet.

If the wall template is damaged or unusable, measure and 
mark the wall with the dimensions described in Step 4.

3. Mark both end holes of the mounting plate through the wall 

template.

4. Remove the wall template and check the markings:

The bottom edge line must be 18

⁵⁄₁₆

" (46.5 cm) from the 

bottom of the upper cabinet, and must be level.

The end holes must be 15

¹⁄₂

" (39.4 cm) from the bottom 

edge of the upper cabinet, and must be on a level line with 
each other. They must each be 14

¹⁄₈

" (35.9 cm) from the 

centerline.

5. With the support tabs facing forward (see illustrations in 

“Locate Wall Stud(s)” section), align the mounting plate center 
markers to the centerline on the wall, making sure its bottom 
edge is aligned to the horizontal line drawn in Step 3, and that 
the end holes are properly marked. Make sure the mounting 
plate is level.

6. Holding the mounting plate in place, find the wall stud 

centerline(s) drawn in Step 2 of “Locate Wall Stud(s),” and 
mark at least 1, preferably 2 hole(s) through the mounting 
plate, closest to the wall stud centerline(s). See figures 1, 2 
and/or 3 in “Possible Wall Stud Configurations” in “Locate 
Wall Stud(s)” section. The blackened holes in the shaded 
areas are ideal hole locations.

7. Set the mounting plate aside.

Wall Venting Installation Only

8. Mark the centerline 3/8" (1 cm) down from the bottom edge of 

the upper cabinet.

9. Using measuring tape, measure out 6" (15.2 cm) on both sides 

of the centerline, and mark.

10. Measure down 4" (10.2 cm) from the mark made in Step 8, 

and mark.

11. Using a straightedge, draw the 2 horizontal, level lines through 

the marks made in steps 8 and 10.

12. Draw the 2 vertical, plumb lines down from the marks made in 

Step 9 to complete the 12" x 4" (30.5 x 10.2 cm) rectangle. 
This is the venting cutout area.

13. Cut a 3/4" (19 mm) hole in one corner of the cutout area.
14. Using a keyhole saw, cut out the venting cutout area.

Drill Holes in Rear Wall

In addition to being installed on at least 1 wall stud, the mounting 
plate must attach to the wall at both end holes. If the end holes 
are not over wall studs, use two 1/4-20 x 3" round-head bolts with 
toggle nuts; if 1 end hole is over a wall stud, use 1 lag screw and 
one 1/4-20 x 3" round-head bolt with toggle nut; or if both end 
holes are over wall studs, use 2 lag screws. Following are 
3 installation configurations.

Installation for No Wall Studs at End Holes 
(Figures 1 and 2)

1. Drill 3/4" (19 mm) holes through the wall at both end holes 

marked in Step 3 of “Mark Rear Wall.”

2. Drill 3/16" (5 mm) hole(s) into the wall stud(s) at the hole(s) 

marked in Step 6 of “Mark Rear Wall.” Refer to figures 1 and 2 
in “Possible Wall Stud Configurations” in “Locate Wall Stud(s)” 
section.

Installation for Wall Stud at One End Hole (Figure 3)

1. Drill a 3/16" (5 mm) hole into the wall stud at the end hole 

marked in Step 3 of “Mark Rear Wall.”

2. If installing on a second wall stud, drill a 3/16" (5 mm) hole into 

the wall stud at the other hole marked in Step 6 of “Mark Rear 
Wall.” Refer to Figure 3 in “Possible Wall Stud Configurations” 
in “Locate Wall Stud(s)” section.

3. Drill a 3/4" (19 mm) hole through the wall at the other end hole.

Installation for Wall Studs at Both End Holes (Figure 4)

1. Drill 3/16" (5 mm) holes into the studs at the end holes marked 

in Step 3 of “Mark Rear Wall.”
