Rigid metal vent is recommended. ■ 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: ■ Use no more than three 90° elbows. ■ Make sure there is a minimum of 24" (61.0 cm) of straight vent between the elbows if more than 1 elbow is used. ■ Do not install 2 elbows together. ■ Use clamps or duct tape 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. ■ The size of the vent should be uniform. 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 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. Venting Methods This canopy hood is factory set for venting through the roof or wall. A 3¹⁄₄" x 10" (8.3 x 25.4 cm) rectangular vent system is needed for installation (not included). The hood exhaust opening is 3¹⁄₄" x 10" (8.3 x 25.4 cm). Vent system can terminate either through the roof or wall. To vent out of the top of the range hood and through a wall, a 90° elbow is needed. See "Install Range Hood" section for details for installing the damper. NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that gently reduce performance. A. For installations with canopy only. 70" (177.8 cm) minimum above electric cooking surface. 76" (193.0 cm) minimum above gas cooking surface. B. For installations with optional duct cover. 82" (208.3 cm) minimum above electric cooking surface. 88" (223.5 cm) minimum above gas cooking surface. IMPORTANT: Minimum distance "X" : 24" (61.0 cm) to electric cooking surface and 30" (76.2 cm) to gas cooking surface. Suggested maximum distance "X" : 36" (91.4 cm) 5
