WARNING
•This appliance is intended for normal residential use. It is not approved
for commercial use, outdoor installation, or any other application not
specifically allowed by this manual.
•This appliance requires connection to a 3-prong or 4-prong, 240VAC
single-phase (split-phase), 60Hz grounded electrical source. When
installed, appliance must be electrically grounded in accordance with
local codes or, in the absence of local codes, with the National Electrical
Code, NFPA 70 or the Canadian Electric Code, CSA C22.1-02.
•Proper installation is the responsibility of the installer. Any adjustment
and service should be performed only by qualified oven installers or
service technicians.
•Product failure due to improper installation is not covered under
warranty.

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.
•Read all of the installation
manual before installing the
oven.
•Disconnect power before
servicing.
•Remove all packing material
before connecting the electrical
supply.
•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.
•Injuries may result from misuse
of appliance doors such as
stepping, leaning, or sitting on
the doors.
•Maintenance – Keep appliance
area clear and free from
combustible materials, gasoline,
and other flammable vapors
and liquids.
•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 use replacement parts
that have not been
recommended by the
manufacturer (e.g. parts made
at home using a 3D printer).
•Proper Disposal of Your
Appliance – Dispose of or recycle
your appliance in accordance
with Federal and Local
Regulations. Contact your local
authorities for the

•Effective January 1, 1996, the National Electrical Code requires that new
construction (not existing) utilize a 4-conductor connection to an electric
oven. When installing an electric oven in new construction, mobile home,
recreational vehicle, or an area where local codes prohibit grounding
through the neutral conductor, refer to the section on 4-wire connections
•An appropriately sized, UL conduit connector must be used to correctly
attach the conduit to the junction box.
•DO NOT shorten the flexible conduit. A UL listed or CSA approved conduit
connector must be securely attached to the junction box and the flexible
conduit must be securely attached to the connector clamp. If the flexible
conduit will not fit within the clamp, do not install the oven until a clamp
of the proper size is obtained.
