For the most efficient and quiet operation: ■ 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 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. 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. Vent System Vent Piece 45° elbow 2.5 ft (0.8 m) Example vent system 90˚ elbow 6 ft (1.8 m) Wall cap 2 ft (0.6 m) 1 - 90° elbow 1 - wall cap 8 ft (2.4 m) straight System length = 5.0 ft (1.5 m) = 0.0 ft (0.0 m) = 8.0 ft (2.4 m) = 13.0 ft (3.9 m) Maximum Recommended Length 7" (17.8 cm) Round Vent 3¹⁄₄" x 10" (8.3 x 25.4 cm) Rectangular Vent = 50 ft (15.2 m) = 35 ft (10.7 m) 90° elbow 5.0 ft (1.5 m) 3¹⁄₄" x 10" (8.3 cm x 25.4 cm) flat elbow 12.0 ft (3.7 m) 7" (17.8 cm) wall cap 0.0 ft (0.0 m) 3¹⁄₄" x 10" (8.3 cm x 4.5 ft 25.4 cm) to 7" (17.8 cm) (1.4 m) 3¹⁄₄" x 10" (8.3 cm x 25.4 cm) to 7" (17.8 cm) 90° elbow 5.0 ft (1.5 m) Electrical Requirements Observe all governing codes and ordinances.
