/8" (1 cm) down from the bottom edge
of the upper cabinet.
Using measuring tape, measure out 6"
(15.2 cm) on both
sides of the centerline, and mark.
Measure down 4" (10.2 cm) from the mark made in step 8
and mark.
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
3
/
16-24 x 3" round head bolts with
toggle nuts; if 1 end hole is over a wall stud, use 1 lag screw and
one
3
/16-24 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
5
/8" (16 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 the “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 the “Locate Wall Stud(s)” section.
3. Drill a
5
/8" (16 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)
hole into the wall stud at the end hole
marked in Step 3 of “Mark Rear Wall.
No Wall Studs at End Holes (Figures 1 and 2)
NOTE: The mounting plate must be secured to the wall on
atleast 1 wall stud as well as at both ends.
1. With the support tabs of the mounting plate facing forward,
insert
3
/16
-24 x 3" round-head bolts through both end holes of
mounting plate.
2. Start toggle nuts on bolts from the back of the mounting
plate. Leave enough space for the toggle nuts to go
through the wall and to open.
3. Position mounting plate on the wall.
4. Push the 2 bolts with toggle nuts through the drywall and
finger tighten the bolts to make sure toggle nuts have
opened against drywall.
5. Insert lag screw(s) into the hole(s) drilled into wall stud(s) in
Step 2 of “Installation for No Wall Studs at End Holes” in the
“Drill Holes in Rear Wall” section.
6. Check alignment of mounting plate, making sure it is level.
7. Securely tighten all lag screws and bolts.
