See STEP 2: USING THE TEMPLATE for details. 3. EXHAUST DUCT The hood exhaust has been designed to match with a standard 31/4"×10" (8.3 cm × 25.4 cm) rectangular duct. If a round duct is desired, a rectangular-to-round transition adaptor must be used. Note: Round duct elements with a 6" diameter are recommended. MAXIMUM DUCT LENGTH For satisfactory air movement (CFM) the total duct length should not exceed 130 feet (39.6 m) of 31/4"×10" (8.3 cm × 25.4 cm) rectangular duct. This 130 feet maximum can be comprised entirely of straight duct or the total amount of straight duct used plus the equivalent amount in feet of elbows, transitions, wall or roof caps, etc. which were used. The drawings below show approximate measurements for typical round duct elements [with a 6" (15.2 cm) diameter] and rectangular duct elements 31/4"×10" (8.3 cm × 25.4 cm). For example, a 90 degree elbow, equivalent to 10 ft. (3 m), and a transition adaptor, equivalent to 5 ft. (1.5 m), can be used with a maximum of 115 feet of straight duct. Transition Adaptor - 5 ft. (1.5 m) Wall Cap - 40 ft. (12 m) 90O Elbow - 25 ft. (7.8 m) 45O Elbow - 5 ft. (1.5 m) 90O Elbow - 10 ft. (3 m) Roof Cap - 24 ft. (7.3 m) 45O Elbow - 5 ft.
