5.
With the support tabs facing forward (see illustrations in
“Locate Wall Stud(s)” section, align the mounting plate center
marker to the centerline on the wall, making sure its top edge
is aligned with the horizontal line drawn in Step 3. Make sure
the mounting plate is level.
6.
Through the mounting plate, mark a hole at each end of the
mounting plate. These are the mounting holes.
7.
Holding the mounting plate in place, and making sure it is
aligned with the top edge line, centerline and the mounting
holes, find the wall stud centerline(s) drawn in Step 2 of
“Locate Wall Stud(s).” Mark at least 1, preferably 2 hole(s)
through the mounting plate, closest to the wall stud
centerline(s). See illustrations in “Locate Wall Stud(s)” section.
The blackened holes in the shaded areas are ideal hole
locations.
8.
Set the mounting plate aside.
Wall Venting Installation Only
9.
Mark the centerline 3/8" (1 cm) down from the bottom edge of
the upper cabinet.
10.
Using measuring tape, measure out 6" (15.2 cm) on both sides
of the centerline, and mark.
11.
Measure down 4" (10.2 cm) from the mark made in Step 9,
and mark.
12.
Using a straightedge, draw the 2 horizontal, level lines through
the marks made in steps 9 and11.
13.
Draw the 2 vertical, plumb lines down from the marks made in
Step 7 to complete the 12" x 4" (30.5 x 10.2 cm) rectangle.
This is the venting cutout area.
14.
Cut a 3/4" (19 mm) hole in one corner of the cutout area.
15.
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 through mounting holes on both
ends. If the mounting holes are not over wall studs, use two 3/16-
20 x 3" hex-head bolts with toggle nuts. If 1 hole is over a wall
stud, use 1 lag screw and one 3/16-20 x 3" hex-head bolt with
toggle nut. If both end mounting holes are over wall studs, use
2 lag screws.
1.
Drill 5/8" (16 mm) hole(s) through the wall at holes marked for
3/16-20 x 3" hex-head bolt(s) with toggle nut(s).
2.
Drill 1/8" (3 mm) hole(s) into the wall stud(s) at the hole(s)
marked in Step 7 of “Mark Rear Wall.” Refer to illustrations in
“Possible Wall Stud Configurations” in “Locate Wall Stud(s)”
section.
Attach Mounting Plate to Wall
NOTE:
Secure the mounting plate to the wall at both end
mounting holes drilled into the wall studs and/or drywall using
either 3/16-20 x 3" hex-head bolts with toggle nuts or 3/16 x 2"
lag screws.
Refer to illustrations in “Locate Wall Stud(s)” section.
1.
With the support tabs of the mounting plate facing forward,
insert 3/16-20 x 3" hex-head bolt(s) through end mounting
hole(s) that is(are) not over wall stud(s). Start toggle nut(s) on
bolt(s) from the back of the mounting plate. Leave enough
space for the toggle nut(s) to go through the wall and to open.
2.
Position mounting plate on the wall.
3.
Push the bolt(s) with toggle nut(s) through the drywall, and
finger tighten the bolt(s) to make sure toggle nut(s) has(have)
opened against drywall.
4.
Insert lag screw(s) into the hole(s) drilled into wall stud(s) in
Step 2 of “Drill Holes in Rear Wall.”
5.
Check alignment of mounting plate, making sure it is level.
6.
Securely tighten all lag screws and bolts.
