INSTALLATION INSTRUCTIONS EXTERIOR-MOUNTED VENT MOTOR CAUTION: To reduce the risk of fire and electrical shock, install the downdraft only with remote blower systems that are sold by Whirlpool Corporation. Model numbers UXI0600DYS (600 cfm) and UXI01200DYS (1200 cfm). NOTE: Exterior-mounted vent motor installations require an approved in-line blower motor system. Model numbers UXI0600DYS (600 cfm) and UXI1200DYS (1200 cfm) are available from your dealer or authorized parts supplier. See "Blower motor system" in the "Accessories" section. Venting Methods Determine which venting method is best for your application. Vent system can terminate through the wall or roof. A wall cap or roof cap is required. NOTES: Built-In Cabinet Locations To attic installed in-line blower motor system ■ Venting through a concrete slab is not recommended. ■ The in-line blower motor system must be placed in an enclosed area and can be located in a utility room, basement, crawl space or attic. Observe all governing codes and ordinances. ■ 10" (25.4 cm) round vent duct is required for connections to the retractable downdraft vent system outlet cover and the in-line blower motor inlet and outlet covers. 10" (25.4 cm) round vent duct is recommended for the retractable downdraft vent system with in-line blower motor system. Transitioning to different size ducting will reduce the efficiency of the retractable downdraft vent system. To basement, crawlspace or utility room installed in-line blower motor system Calculating Vent System Length Island Location-Front Vent To attic installed in-line blower motor system Island Location-Rear Vent It is recommended that you use round vent instead of rectangular vent, especially if elbows are required. If rectangular vent is required, it should be transitioned to 10" (25.4 cm) round vent as soon as possible. Maximum Length of Vent System Vent Length 10" (25.4 cm) round 60 ft (18.3 m) To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system. To basement, crawlspace or utility room installed in-line blower motor system Vent Piece 45° elbow 10" (25.4 cm) Round 2.5 ft (0.8 m) To attic installed in-line blower motor system 90° elbow 5.0 ft (1.5 m) To basement, crawlspace or utility room installed in-line blower motor system The maximum equivalent vent lengths of 10" (25.4 cm) round vents - 60 ft (18.3 m). 2 - 90° elbows = 10.0 ft (3 m) 10 ft (3 m) straight = 10.0 ft (3 m) Length of 10" (25.4 cm) = 20 ft (6 m) system NOTE: The exterior-mounted vent motor requires a separate wiring cable that should be installed at the same time the vent work is installed. 16
