Calculating Vent System LengthTo calculate the length of the system you need, add theequivalent feet (meters) for each vent piece used in the system.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) 0.0 ftwall cap (0.0 m)31/4"x 10" (8.3 cm x 25.4 cm) 4.5 ftto 6" (15.2 cm) transition (1.4 m)6" (15.2 cm) to 31/4'' x 10" 1 ft(8.3 cm x 25.4 cm) transition (0.3 m)31/4"x 10" (8.3 cm x 25.4 cm) 5.0 ftto 6" (15.2 cm) 90 ° elbow (1.5 m)transition6" (15.2 cm) to 31/4'' x 10" 5.0 ft(8.3 cm x 25.4 cm) 90 ° elbow (1.5 m)transition31/4"x 10" (8.3 cm x 25.4 cm) 5.0 ft90 ° elbow (1.5 m)31/4"x 10" (8.3 cm x 25.4 cm) 12.0 ftflat elbow (3.7 m)31/4'' x 10" (8.3 cm x 25.4 cm) 0.0 ftwall cap (0.0 m)Example vent system90 ° embow1- 90 ° elbow8 ft (2.4 m) straight1 - wall capSystem length6 ft (1.8m)= 5 ft (1.5 m)= 8 ft (2.4 m)= 0 ft (0 m)= 13 ft (3.9 m)wall capUNOTE: Flexible vent is not recommended. Flexible vent createsback pressure and air turbulence that greatly reduceperformance.IMPORTANT: The cooktop must be electrically grounded inaccordance with local codes and ordinances, or in the absenceof local codes, with the National Electrical Code, ANSl/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.
