SECTION 2 - INSTALLATION
NOTE: All aspects of the oven installation, including placement, utility connections, and ventilation requirements, must
conform with any applicable local, national, or international codes. These codes supercede the requirements and
guidelines provided in this manual.
NOTE: In the USA, the oven installation must conform with local codes. In the absence of local codes, gas oven
installations must conform with the National Fuel Gas Code, ANSI Z223.1. Gas and electric ovens, when installed, must
be electrically grounded in accordance with local codes, or in the absence of local codes, with the National Electrical Code
(NEC), or ANSI/NFPA70.
NOTE: In Canada, the oven installation must conform with local codes. In the absence of local codes, gas oven
installations must conform with the Natural Gas Installation Code, CAN/CGA-B149.1, or the Propane Gas Installation
Code, CAN/CGA-B149.2, as applicable. Gas and electric ovens, when installed, must be electrically grounded in
accordance with local codes, or in the absence of local codes, with the Canadian Electrical Code CSA C22.2.
NOTE: In Australia, the oven installation must conform with any requirements of the appropriate statutory authority. Gas
oven installtions must conform with AGA Code, AG601.
WARNING - After any conversions, readjustments, or service work on the oven:
• Perform a gas leak test.
• Test for correct air supply, particularly to the
burner blower.

IMPORTANT - Additional electrical information is provided on the oven's serial plate, and on the wiring diagram inside
the machinery compartment.
• Test for proper combustion and gas supply.
• Check that the ventilation system is in operation.
CAUTION: To reduce the risk of fire, the appliance is to be mounted on floors of noncombustible
construction with noncombustible flooring and surface finish and with no combustible material against the
underside thereof, or on noncombustible slabs or arches having no combustible material against the
underside thereof, such construction shall in all cases extend not less than 12 inches (304.8mm) beyond the
equipment on all sides.
WARNING - Keep the appliance area free and clear of combustibles.
WARNING - The oven must be installed on an even (level) non-flammable flooring and any adjacent walls
must be non-flammable. Recommended minimum clearances are specified in the Description section of
this Manual.
WARNING - Do not obstruct the flow of combustion and ventilation air to and from your oven. There must
be no obstructions around or underneath the oven. Constructional changes to the area where the oven is
installed shall not affect the air supply to the oven.
CAUTION - For additional installation information, contact your local Authorized Service Agent.
NOTE - There must be adequate clearance between the oven and combustible construction. Clearance
must also be provided for servicing and for proper operation.
NOTE - An electrical wiring diagram for the oven is located inside the machinery compartment.
