IMPORTANT SAFETY INSTRUCTIONS
WARNING: To reduce the risk of fire, electrical shock, injury to persons, or
damage when using the appliance, follow basic precautions, including the
following:
•Proper Installation – The
appliance, when installed, must
be electrically grounded in
accordance with local codes, or
in the absence of local codes,
with the National Electrical
Code, ANSI/NFPA 70 or the
Canadian Electrical Code, CSA
C22.1-02. In Canada, the
appliance must be electrically
grounded in accordance with
Canadian Electrical Code. Be
sure your appliance is properly
installed and grounded by a
qualified technician.
•WARNING: Never use this
appliance for warming or
heating the room.
•WARNING: Never cover any
slots, holes or passages in the
oven bottom or cover an entire
rack with materials such as
aluminum foil. Doing so blocks
airflow through the oven and
may cause carbon monoxide
poisoning. Aluminum foil linings
may also trap heat, causing a
fire hazard.
•CAUTION: Do not store items of
interest to children in cabinets
above an oven – children
climbing on the oven to reach
items could be seriously injured.
•Do Not Leave Children Alone –
Children should not be left alone
or unattended in area where
appliance is in use. They should
never be allowed to sit or stand
on any part of the appliance.
•Wear Proper Apparel – Loose-
fitting or hanging garments
should never be worn while
using the appliance.
•User Servicing – Do not repair or
replace any part of the
appliance unless specifically
recommended in the manual. All
other servicing should be
referred to a qualified
technician.
•Do not store or use flammable
materials in or near an oven,
including paper, plastic, pot
holders, linens, wall coverings,
curtains, drapes and gasoline or
other flammable vapors and
liquids.
•Use this appliance only for its
intended purpose as described
in this manual. This appliance is
not intended for storage.
•Do Not Use Water on Grease
Fires – Smother fire or flame or
use dry chemical or foam-type
extinguisher.

IMPORTANT SAFETY INSTRUCTIONS
•Use Only Dry Potholders – Moist
or damp potholders on hot
surfaces may result in burns
from steam. Do not let potholder
touch hot heating elements. Do
not use a towel or other bulky
cloth.
•Use Care When Opening Door –
Let hot air or steam escape
before removing or replacing
food.
•DO NOT TOUCH HEATING
ELEMENTS OR INTERIOR
SURFACES OF OVEN – Heating
elements may be hot even
though they are dark in color.
Interior surfaces of an oven
become hot enough to cause
burns. During and after use, do
not touch, or let clothing or other
flammable materials contact
heating elements or interior
surfaces of oven until they have
had sufficient time to cool. Other
surfaces of the appliance may
become hot enough to cause
burns – among these surfaces
are oven vent openings, surfaces
near these openings, oven
doors, windows of oven doors,
and crevices around the oven
doors.
•Care must be taken to prevent
aluminum foil and meat probes
from contacting heating
elements.
•Do Not Heat Unopened Food
Containers – Build-up of
pressure may cause container to
burst and result in injury.
•Keep Oven Vent Ducts
Unobstructed.
•Never broil with door open.
Open-door broiling is not
permitted due to overheating of
control panel.
•Avoid scratching or impacting
glass doors or control panels.
Doing so may lead to glass
breakage. Do no cook on a
product with broken glass.
Shock, fire or cuts may occur.
•Placement of Oven Racks –
Always place oven racks in
desired location while oven is
cool. If rack must be moved
while oven is hot, do not let
potholder contact hot heating
element in oven.
•Disconnect power before
servicing.
•Do not use replacement parts
that have not been
recommended by the
manufacturer (e.g. parts made
at home using a 3D printer).
•Injuries may result from misuse
of appliance doors such as
stepping, leaning, or sitting on
the doors.

area clear and free from
combustible materials, gasoline,
and other flammable vapors
and liquids.
•Clean Only Parts Listed in
Manual.
•Do Not Clean Door Gasket – The
door gasket is essential for a
good seal. Care should be taken
not to rub, damage, or move the
gasket.
•Do Not Soak Removable

elements should never be
immersed in water.
•Do not let cooking grease or
other flammable materials

cleaning oven.
•In the event of ignition inside the
oven during self-clean, turn off
the oven and wait for the fire to
extinguish. DO NOT FORCE THE
