¦ The vent system must have a damper. If roof or wall cap has a damper, do not use damper supplied with the range hood. ¦ Use caulking to seal exterior wall or roof opening around the cap. Cold Weather Installations An additional back draft damper should be installed to minimize backward cold air flow and a thermal break should be installed to minimize conduction of outside temperatures as part of the vent system. The damper should be on the cold air side of the thermal break. The break should be as close as possible to where the vent system enters the heated portion of the house. Makeup Air Local building codes may require the use of make up air systems when using ventilation systems greater than specified CFM of air movement. The specified CFM varies from locale to locale. Consult your HVAC professional for specific requirements in your area. Venting Methods Vent system can terminate either through the roof or wall. Use 3..." x 10" (8.3 x 25.4 cm) with a maximum vent length of 35 ft (10.7 m) or 6" (15.2 cm) or larger round vent with a maximum length of 50 ft (15.2 m) for vent system. NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that gently reduces performance. Roof Venting A E B C D A. 6" (15.2 cm) or larger round vent or a 3..." x 10" (8.3 x 25.4 cm) rectangular vent through roof B. Round vent: use 6" (15.2 cm) or larger round damper (purchased separately) C. Round vent: use 3..." x 10" (8.3 x 25.4 cm) to 6" (15.2 cm) or larger diameter transition piece (purchased separately) D. 24" (61.0 cm) - 30" (76.2 cm) above cooking surface E. Roof cap Wall Venting A B C D E A. 6" (15.2 cm) or larger round vent or a 3..." x 10" (8.3 x 25.4 cm) rectangular vent through the wall B. Round vent: use 3..." x 10" (8.3 x 25.4 cm) to 6" (15.2 cm) or larger diameter transition piece (purchased separately) C. 3..." x 10" (8.3 x 25.4 cm) through the wall D. 24" (61.0 cm) - 30" (76.2 cm) above cooking surface E. Wall cap Calculating Vent System Length To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system. 6" (15.2 cm) or Larger Round Vent System Vent Piece Round 45° elbow 2.5 ft (0.8 m) 90° elbow 5.0 ft (1.5 m) 6" (15.2 cm) or larger 0.0 ft wall cap (0.0 m) 3..." x 10" (8.3 cm x 25.4 cm) 4.5 ft to 6" (15.2 cm) or larger (1.4 m) 3..." x 10" (8.3 cm x 25.4 cm) 5.0 ft to 6" (15.2 cm) or larger (1.5 m) 90° elbow Example vent system Wall cap 90° elbow 6 ft (1.8 m) 2 ft (0.6 m) Maximum Recommended Length = 50 ft (15.2 m) 1 - 90° elbow = 5.0 ft (1.5 m) 1 - wall cap = 0.0 ft (0.0 m) 8 ft (2.4 m) straight = 8.0 ft (2.4 m) Length of 7" (17.8 cm) system = 13.0 ft (3.9 m) 3..." x 10" (8.3 cm x 25.4 cm) Vent System Vent Piece 3..." x 10" (8.3 cm x 25.4 cm) 5.0 ft 90° elbow (1.5 m) 3..." x 10" (8.3 cm x 25.4 cm) 12.0 ft flat elbow (3.7 m) 3..." x 10" (8.3 cm x 25.4 cm) 0.0 ft wall cap (0.0 m) Example vent system 3..." x 10" (8.3 x 25.4 cm) elbow Wall cap 6 ft (1.8 m) 2 ft (0.6 m) Maximum Recommended Length = 35 ft (10.7 m) 1 - 90° elbow = 5.0 ft (1.5 m) 8 ft (2.4 m) straight = 8.0 ft (2.4 m) 1 - wall cap = 0.0 ft (0.0 m) Length of 3..." x 10" (8.3 cm x 25.4 cm) = 13.0 ft (3.9 m) system Electrical Requirements Observe all governing codes and ordinances. Ensure that the electrical installation is adequate and in conformance with National Electrical Code, ANSI/NFPA 70 (latest edition), or CSA Standards C22.1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 (latest edition) and all local codes and ordinances. If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. A copy of the above code standards can be obtained from: National Fire Protection Association One Batterymarch Park Quincy, MA 02269 CSA International 8501 East Pleasant Valley Road Cleveland, OH 44131-5575 ¦ A 120 Volt, 60 Hz., AC only, 15-amp, fused electrical circuit is required. ¦ If the house has aluminum wiring follow the procedure below: 1. Connect a section of solid copper wire to the pigtail leads. 2. Connect the aluminum wiring to the added section of copper wire using special connectors and/or tools designed and UL listed for joining copper to aluminum. Follow the electrical connector manufacturer's recommended procedure. Aluminum/copper connection must conform with local codes and industry accepted wiring practices. ¦ Wire sizes and connections must conform with the rating of the appliance as specified on the model/serial rating plate. The model/serial plate is located behind the filter on the rear wall of the range hood. ¦ Wire sizes must conform to the requirements of the National Electrical Code, ANSI/NFPA 70 (latest edition), or CSA Standards C22. 1-94, Canadian Electrical Code, Part 1 and C22.2 No. 0-M91 (latest edition) and all local codes and ordinances.
