INSTALLATION
Before Installing
Proper Location and Dimensions
CAUTION
-
The cabinet base platform must be able to
support 202 lbs (92 kg) for this appliance. 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 appliance. Make sure the base is level and
the front of the cabinet is square. If the cabinet
base is not level, the oven racks will tend to slide
out when opening the door. -
Make sure the cabinets and wall coverings
around the oven can withstand the temperature
(up to 194 ℉ (90 ℃)) generated by the oven.
Discoloration, delamination or melting may
occur. -
DO NOT remove spacers c on the side walls of
the built-in oven. These spacers center the oven
in the space provided. The oven must be
centered to prevent excess heat buildup that
may result in heat damage or fire. -
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). -
The information in this manual should be
followed exactly. Failure to do so could result in
fire or electrical shock, causing property
damage, personal injury or death. -
DO NOT put any weight on the oven door. Never
allow anyone to climb, sit, stand or hang on the
oven door. The oven could be tipped and injury
might result from contact with hot food or the
oven itself. -
DO NOT block the oven air exhaust located at
the bottom of the oven. Blocking the exhaust
may cause cabinet damage and product
malfunction. -
The junction box a must be flush with the
conduit opening b of the cabinet as shown
below. -
Allow at least a 23″ clearance for the door depth
when it is open. -
Do not remove the gliding racks from the base
packing. Gliding racks are attached separately to
the top and bottom of the oven.
NOTE
-
If marks, blemishes or the cutout opening are
visible above the installed appliance, it may be
necessary to add wood shims under the runners
and front trim until the marks or opening are
