INSTALLATION REQUIREMENTS
The first step of the installation is measure the current cutout dimensions and compare them to
the cutout dimensions shown below. Little or no cabinet work may be necessary.
IMPORTANT NOTE
• The cabinet base platform must be able to support 190lbs (86kg) for a Single built-in oven, 325lbs
(147kg) for double built-in oven. If the cabinet does not have a solid bottom, two braces or runners
must be installed level with the bottom of the cutout to support the weight of the oven. Make sure
the base is level and the front of the cabinet is square. If the cabinet base is not level, the oven glides
will tend to slide out when opening the door.
• If marks, blemishes or the cutout opening are visible above the installed oven, it may be necessary
to add wood shims under the runners and front trim until the marks or opening are covered.
• If the cabinet does not have a front frame and the sides are less than 3/4" (1.9 cm) thick, shim both
sides equally to establish the cutout width.
• The junction box must be flush with the rear wall of the cabinet as shown below.
• Allow at least a 23" clearance for the door depth when it is open.
• Kitchen cabinets in contact with the oven must be heat resistant up to 194°F (90°C), and fronts of
nearby units up to at least 158°F (70°C).
