The other end of the duct can be vented into an existing hood, or to the outside in a manner consistent with local
building codes.
The exhaust duct must not be less than 4" (101.5 mm) in diameter, and a recommended maximum length of 4
to 6 feet (1219-1829 mm) , depending on operating conditions. The duct should be made of metal suitable for
high temperature use. Be sure there are no bends in the duct that will restrict air flow. Depending on the
length of the duct required, it may be necessary to have a supplementary exhaust system to ensure adequate
air flow.
The exhaust system must support 135 cfm.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE APPLICABLE
PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL ELECTRICAL CODES.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY AND PLACE A TAG AT THE DISCONNECT
SWITCH TO INDICATE YOU ARE WORKING ON THE CIRCUIT.
WARNING: APPLIANCES EQUIPPED WITH A FLEXIBLE ELECTRIC SUPPLY CORD ARE PROVIDED WITH
A FOUR-PRONG GROUNDING PLUG. IT IS IMPERATIVE THAT THIS PLUG BE CONNECTED INTO A
PROPERLY GROUNDED FOUR-PRONG RECEPTACLE. IF THE RECEPTACLE IS NOT THE PROPER
GROUNDING TYPE, CONTACT AN ELECTRICIAN. DO NOT REMOVE THE GROUNDING PRONG FROM
THIS PLUG.
Measure the incoming power supply with a volt ohmmeter. The supply MUST measure 197 volts with no load
as a minimum.
For Cord-Connected Ovens
Plug the oven into a dedicated circuit outlet of the appropriate NEMA style and rating.
For Hard-Wired Ovens
Have a qualified electrician wire the oven into a properly rated dedicated circuit, connecting to the pigtails in the
junction box on the rear of the oven. Use the appropriate conduit, wire and connectors.
For a Single-Phase 240 Volt Oven
Both "hot legs" must read 120 volts to ground. The "stinger" leg must not be attached to a single-phase oven.
For a 3-Phase 240 Volt Oven Only (Does not apply to 208 Volt Oven)
When connecting a 3-phase 240 volt oven, the "stinger" leg of the supply circuit MUST be connected as follows:
For a hard-wired oven, connect the stinger to the blue pigtail. The blue wire is marked with a label indicating
the stinger connection.
For a cord-connected oven, the stinger must be wired to the receptacle at the pin location opposite the ground
lug (Fig. 2).
The "stinger" leg of a 240 volt, 3-phase system can be easily identified using a voltmeter. The line-to-ground
voltage of the stinger will read approximately 210 volts. The line-to-ground voltage of the other two legs will read
approximately 120 volts.
