Venting Requirements (Vented Models Only) ■ Vent system must terminate to the outdoors, except for nonvented (recirculating) installations. ■ Do not terminate the vent system in an attic or other enclosed area. ■ Do not use a 4" (10.2 cm) laundry-type wall cap. ■ Use a 6" (15.2 cm) or larger round metal vent or a 3¹⁄₄" x 10" (8.3 x 25.4 cm) rectangular metal vent. Rigid metal vent is recommended. Plastic or metal foil vent is not recommended. Roof Venting A E B C Wall Venting A B C E ■ The length of vent system and number of elbows should be kept to a minimum to provide efficient performance. For the most efficient and quiet operation: D D ■ Use no more than three 90° elbows. ■ Make sure there is a minimum of 24" (61 cm) of straight vent between the elbows if more than 1 elbow is used. ■ Do not install 2 elbows together. ■ Use clamps to seal all joints in the vent system. ■ 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. A. 6" (15.2 cm) or larger round vent or a 3¹⁄₄" 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 3¹⁄₄" 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 electric cooking surface 27" (68.6 cm) - 30" (76.2 cm) above gas cooking surface E. Roof cap A. 6" (15.2 cm) or larger round vent or a 3¹⁄₄" x 10" (8.3 x 25.4 cm) rectangular vent through the wall B. Round vent: use 3¹⁄₄" x 10" (8.3 x 25.4 cm) to 6" (15.2 cm) or larger diameter transition piece (purchased separately) C. 3¹⁄₄" x 10" (8.3 x 25.4 cm) through the wall D. 24" (61.0 cm) - 30" (76.2 cm) above electric cooking surface 27" (68.6 cm) - 30" (76.2 cm) above gas 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. Makeup Air Local building codes may require the use of makeup 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. 6" (15.2 cm) or Larger Round Vent System Vent Piece Round 45° elbow 2.5 ft (0.8 m) Venting Methods Vent system can terminate either through the roof or wall. Use 3¹⁄₄" 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. 90° elbow 6" (15.2 cm) or larger wall cap 5.0 ft (1.5 m) 0.0 ft (0.0 m) 3¹⁄₄" x 10" (8.3 cm x 25.4 cm) 4.5 ft to 6" (15.2 cm) or larger (1.4 m) 3¹⁄₄" x 10" (8.3 cm x 25.4 cm) to 6" (15.2 cm) or larger 90° elbow 5.0 ft (1.5 m) 5
