7Example vent systemNOTE: For external venting, flexible vent is not recommended.Flexible vent creates back pressure and air turbulence thatgreatly reduce performance.Electrical Requirements - U.S.A. OnlyIf codes permit and a separate ground wire is used, it isrecommended that a qualified electrical installer determine thatthe ground path and wire gauge are in accordance with localcodes.Do not use an extension cord.Be sure that the electrical connection and wire size are adequateand in conformance with the National Electrical Code, ANSI/NFPA 70-latest edition and all local codes and ordinances.A copy of the above code standards can be obtained from:National Fire Protection Association1 Batterymarch ParkQuincy, MA 02169-7471WARNING: Improper connection of the equipment-groundingconductor can result in a risk of electric shock. Check with aqualified electrician or service technician if you are in doubt as towhether the appliance is properly grounded. Do not modify thepower supply cord plug. If it will not fit the outlet, have a properoutlet installed by a qualified electrician.Electrical ConnectionTo properly install your range, you must determine the type ofelectrical connection you will be using and follow the instructionsprovided for it here.■ Range must be connected to the proper electrical voltageand frequency as specified on the model/serial number ratingplate. The model/serial number rating plate is located behindthe control panel or on the oven frame behind the storagedrawer panel. Refer to the figures in the “ProductDimensions” section of the “Location Requirements” section.■ This range is manufactured with the neutral terminalconnected to the cabinet. Use a 3-wire, UL listed, 40- or50-amp power supply cord (pigtail) (see following RangeRating chart). If local codes do not permit ground through theneutral, use a 4-wire power supply cord rated at 250 volts,40 or 50 amps and investigated for use with ranges.*The NEC calculated load is less than the total connected loadlisted on the model/serial rating plate.**If connecting to a 50-amp circuit, use a 50-amp rated cord withkit. For 50-amp rated cord kits, use kits that specify use with anominal 1³⁄₈" (34.9 mm) diameter connection opening.■ A circuit breaker is recommended.■ The range can be connected directly to the circuit breakerbox (or fused disconnect) through flexible or nonmetallicsheathed, copper or aluminum cable. See “ElectricalConnection.”■ Allow 2 to 3 ft (61.0 cm to 91.4 cm) of slack in the line so thatthe range can be moved if servicing is ever necessary.■ A UL listed conduit connector must be provided at each endof the power supply cable (at the range and at the junctionbox).■ Wire sizes and connections must conform with the rating ofthe range.■ The wiring diagram is located on the back of the accesspanel in a plastic bag.If connecting to a 4-wire system:This range is manufactured with the ground connected to theneutral by a link. The ground must be revised so the greenground wire of the 4-wire power supply cord is connected to thecabinet. See “Electrical Connection.”Grounding through the neutral conductor is prohibited for newbranch-circuit installations (1996 NEC); mobile homes; andrecreational vehicles, or an area where local codes prohibitgrounding through the neutral conductor.When a 4-wire receptacle of NEMA Type 14-50R is used, amatching UL listed, 4-wire, 250-volt, 40- or 50-amp, range powersupply cord (pigtail) must be used. This cord contains 4 copperconductors with ring terminals or open-end spade terminals withupturned ends, terminating in a NEMA Type 14-50P plug on thesupply end.The fourth (grounding) conductor must be identified by a green orgreen/yellow cover and the neutral conductor by a white cover.Cord should be Type SRD or SRDT with a UL listed strain reliefand be at least 4 ft (1.22 m) long.The minimum conductor sized for the copper 4-wire powercord are:40-amp circuit2 No.-8 conductors1 No.-10 white neutral1 No.-8 green groundingMaximum length = 60 ft (18.3 m)1- 90° elbow = 5 ft (1.5 m)8 ft (2.4 m) straight = 8 ft (2.4 m)1 - wall cap = 0 ft (0 m)System length = 13 ft (3.9 m)90˚ elbow2 ft(0.6 m)6 ft (1.8 m)wall capRange Rating* Specified Rating ofPower Supply Cord Kitand Circuit Protection120/240 Volts 120/208 Volts Amps8.8 - 16.5 KW16.6 - 22.5 KW7.8 - 12.5 KW12.6 - 18.5 KW40 or 50**504-wire receptacle (14-50R)
