INSTALLATION
VI. ELECTRICAL SUPPLY
WARNING
Authorized supplier personnel normally accomplish the connections for the ventilation system, electric supply, and gas supply, as arranged by the customer. Following these connections, the
NOTE: The electric supply installation must satisfy the requirements of the appropriate statutory authority, such as the National Electrical Code (NEC), ANSI/NFPA70, (U.S.A.); the Canadian Electrical Code, CSA C22.2; the Australian Code AG601; or other applicable regulations.
NOTE: The electric supply connection must meet all national and local electrical code requirements.
Check the oven data plate before making any electric supply connections. Electric supply connections must agree with data on the oven data plate. See Figure
A fused disconnect switch or a main circuit breaker (customer furnished) MUST be installed in the electric supply line for each oven. It is recommended that this switch/circuit breaker have lockout/tagout capability.
The supply conductors must be of the size (#14 AWG, copper) recommended. Refer to the wiring diagrams in Section 5 of this manual.
All gas oven electric supply connections are made via the electrical junction box on the rear of the oven, shown in Figure

Oven Data Plate
CAUTION
Before connecting incoming power to the oven, measure the voltage of each input leg to neutral. The expected voltage is approximately 120V. ANY voltage reading exceeding 130V indicates that the supply has a “high” leg.
CONNECTING A “HIGH” LEG TO THE OVEN VOIDS ALL OVEN WARRANTIES. Connecting a “high” leg to the black lead of the oven can severely damage the oven’s electrical and electronic components.
CAUTION
DO NOT CONNECT BLACK WIRE TO HIGH LEG. VOLTAGE OF THE BLACK AND WHITE WIRES MUST BE NO HIGHER THAN 130 VAC
FOR DOMESTIC OVENS (WITHOUT EXTERNAL TRANSFORMERS):
In the junction box on the rear of the oven, connect one 208 - 240V supply line to the black wire and the other 208 - 240V supply line to the red wire. Connect the electric supply ground wire to the oven ground screw located in the junction box. If necessary, have the electrician supply the ground wire. Do NOT use the wiring conduit or other piping for ground connections!
FOR EXPORT OVENS (WITH EXTERNAL TRANSFORMERS):
First, position the transformer on the LEFT REAR wall of the oven (as space permits), and fasten it in place using the supplied mounting hardware.
Then, refer to the appropriate wiring diagram in Section 5 of this manual to determine the correct transformer connections for the supply lines. Connect the electric supply ground wire to the oven ground screw located in the junction box. If necessary, have the electrician supply the ground wire. Do NOT use the wiring conduit or other piping for ground connections!
