Grounded 3 prong outlet   VENTING REQUIREMENTS   Roof venting   Wall venting   roof cap   Recommended vent length   Use 3-1/4" x 10" or 6" vent. The total length of the vent system   including straight vent, elbow, transitions, wall or roof caps   must not exceed the equivalent of 140 feet of   wall cap   3-1/4" x 10" rectangular or 6" diameter round vent. For best   performance, use no more than three 90° elbows. To calculate   the length of system you need, add the equivalent feet for   each vent piece used in the system. See examples below.   3-1/4" x 10"   through-the-wall   3-1/4" x 10"   through-the-roof   3-1/4" x 10" vent system   For wall or roof venting methods:   Recommended standard fittings   3-1/4" x 10"   90° elbow   If the wall exhaust method is chosen, be sure that   there is proper clearance within the wall so the vent   fits properly and the damper blade opens fully.   wall cap   6 ft.   Wall and roof caps must have back-draft damper.   We recommend:   ✔ using rigid metal vent.   2 ft.   1 - 3-1/4" x 10"   90° elbow   = 25 ft.   = 40 ft.   3-1/4" x 10"   90° elbow = 25 ft.   3-1/4" x 10"   to 6" = 5 ft.   3-1/4" x 10"   roof cap = 24 ft.   ✔ that length of vent and number of elbows should   be kept to a minimum to provide efficient   performance.   1 - wall cap   8 feet straight   Length of   = 8 ft.   ✔ that size of vent should be uniform.   ✔ using duct tape to seal all joints in the vent   system.   ✔ using caulking compound to seal exterior wall or   roof opening around cap.   ✔ two elbows should not be installed together.   3-1/4" x 10" system   = 73 ft.   6" vent system   90° elbow   3-1/4" x 10"   90° flat   3-1/4" x 10" 45° elbow   90° elbows   6 ft.   6" = 10 ft.   wall cap   5 ft.   = 20 ft.   = 40 ft.   8 ft.   wall cap =   40 ft.   6" = 5 ft.   elbow= 10 ft.   If the existing vent is round, a rectangular-   to-round adapter must be used and a   rectangular 3" extension vent between the   damper assembly and the adapter must be   installed to prevent sticking of the exhaust   damper.   We do NOT recommend:   ✔ flexible metal vent.   1 - transition   2 - 90° elbows   1 - wall cap   = 2 ft.   NOTE: If flexible metal vent must be used, calculate   each foot of flexible metal vent as two feet of rigid   metal vent. Flexible metal elbows count twice as   much as standard elbows.   8 feet straight   = Length of 6" system = 73 ft.   transition   Because Whirlpool Corporation policy includes a continuous commitment to improve   our products, we reserve the right to change materials and specifications without notice.   Dimensions are for planning purposes only. For complete details, see Installation   Instructions packed with product. Specifications subject to change without notice.   Ref. 8206590   04-17-07   Download from Www.Somanuals.com.
