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.

NOTE: Draw a fifth circle inside area E, through

one of the bottom holes to match the location of a
stud.

For wall-vented: The oven requires a rear wall cutout

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 walt cutout
opening and the exhaust adaptor/mounting plate for

wall-vented.

3. Drill holes on the circles. If there is a stud, drill a 3
/ 16" hole for tag screws. If there is no stud, drill a

3 / 4" hole for toggle bolts. Make sure to use at
least 1 lag screw in a stud, and 4 toggle bolts in

the drywall or the plaster.

4. Attach the plate to the wall. To use spring toggle

heads 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.
