Safety Messages
Your safety and the safety of others are very important.
We have provided many important safety messages in this manual and on your appliance. Always read and
follow all safety messages.
All safety messages will tell you what the potential hazard is, tell you how to reduce the chance of injury,
and tell you what may happen if the instructions are not followed.
WARNING
WARNING
• To reduce the risk of explosion, fire, death, electric shock, injury or scalding to persons when using this
product, follow basic precautions, including the following:
Installation
• Never allow anyone to climb, sit, stand or hang on the oven door. Injury might result from contact with
hot food or the oven itself.
• Do not line the oven walls, racks, bottom, or any other part of the oven with aluminum foil or any other
material. Doing so will disrupt heat distribution, produce poor baking results and cause permanent
damage to the oven interior (aluminum foil will melt to the interior surface of the oven).
• Do not use aluminum foil or any other material to line the oven bottom. Improper installation of oven
liners may result in a risk of electric shock or fire.
• Make sure your appliance is properly installed and grounded by a qualified installer, according to the
installation instructions. Any adjustment and service should be performed only by qualified installers or
service technicians.
• Be certain that all packing materials are removed from the appliance before operating. Keep plastic,
clothes, paper, and other flammable materials away from parts of the appliance that may become hot.
• The electrical power must be shut off while the electrical connections are being made.
• Improper connection of aluminum house wiring to copper leads can result in an electrical hazard or fire.
Use only connectors designed for joining copper to aluminum and follow the manufacturer’s
recommended procedure closely.
This is the safety alert symbol.
This symbol alerts you to potential hazards that can kill or injure you and others. All safety messages
will follow the safety alert symbol and either the word WARNING or CAUTION.
These words mean:
WARNING
You may be killed or seriously injured if you do not follow instructions.
CAUTION
You may be injured or cause damage to the product if you do not follow instructions.

Before Installing
Proper Location and Dimensions
CAUTION
• The cabinet base platform must be able to
support 190 lbs (86 kg) for single built-in oven,
325 lbs (147 kg) 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 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.
• 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).
• DO NOT remove spacers con 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.
• 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.
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
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 amust be flush with the
conduit opening bof the cabinet as shown.
• 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.
