7Calculating Vent System LengthTo calculate the length of the system you need, add theequivalent feet (meters) for each vent piece used in the system.Example vent systemNOTE: Flexible vent is not recommended. Flexible vent createsback pressure and air turbulence that greatly reduceperformance.Electrical RequirementsIMPORTANT: The cooktop must be electrically grounded inaccordance with local codes and ordinances, or in the absenceof local codes, with the National Electrical Code, ANSI/NFPA 70or Canadian Electrical Code, CSA C22.1.This cooktop is equipped with an electronic ignition system thatwill not operate if plugged into an outlet that is not properlypolarized.If codes permit and a separate ground wire is used, it isrecommended that a qualified electrical installer determine thatthe ground path is adequate.A copy of the above code standards can be obtained from:National Fire Protection Association1 Batterymarch ParkQuincy, MA 02169-7471CSA International8501 East Pleasant Valley RoadCleveland, Ohio 44131-5575■ A 120 volt, 60 Hz, AC only, 15-amp, fused electrical circuit isrequired. A time-delay fuse or circuit breaker is alsorecommended. It is recommended that a separate circuitserving only this cooktop be provided.■ Electronic ignition systems operate within wide voltage limits,but proper grounding and polarity are necessary. Check thatthe outlet provides 120-volt power and is correctly grounded.■ The wiring diagrams are provided with this cooktop. See“Wiring Diagrams” on a separate sheet. The wiring diagramsare located on the left underside of the cooktop base.Vent Piece 6" (15.2 cm) Round45° elbow 2.5 ft(0.8 m)90° elbow 5.0 ft(1.5 m)6" (15.2 cm)wall cap0.0 ft(0.0 m)3¹⁄₄" x 10" (8.3 cm x 25.4 cm)to 6" (15.2 cm) transition4.5 ft(1.4 m)6" (15.2 cm) to 3¹⁄₄" x 10"(8.3 cm x 25.4 cm) transition1 ft(0.3 m)3¹⁄₄" x 10" (8.3 cm x 25.4 cm)to 6" (15.2 cm) 90° elbowtransition5.0 ft(1.5 m)6" (15.2 cm) to 3¹⁄₄" x 10"(8.3 cm x 25.4 cm) 90° elbowtransition5.0 ft(1.5 m)3¹⁄₄" x 10" (8.3 cm x 25.4 cm)90° elbow5.0 ft(1.5 m)3¹⁄₄" x 10" (8.3 cm x 25.4 cm)flat elbow12.0 ft(3.7 m)3¹⁄₄" x 10" (8.3 cm x 25.4 cm)wall cap0.0 ft(0.0 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 cap
