Installation Instructions EXHAUSTING THE DRYER (cont.) WARNING USE ONLY METAL 4″ DUCT. DO NOT USE DUCT LONGER THAN SPECIFIED IN THE EXHAUST LENGTH TABLE. Ducting longer than 90 equivalent feet will: • Increase the drying times and the energy cost. • Reduce the dryer life. • Accumulate lint, creating a potential fire hazard. EXAMPLE ONLY The following chart describes an example of one possible ductwork installation. The correct exhaust installation is your responsibility. Problems due to incorrect installation are not covered by the warranty. The length of the exhaust system depends upon the type of duct, number of turns and the type of exhaust hood (wall cap), and all conditions noted below. For satisfactory air movement, the total duct length should not exceed 90 equivalent feet. DUCT PIECES EQUIVALENT RIGID NUMBER EQUIVALENT LENGTH X USED = LENGTH Rigid Metal 1 Ft. X (4) = 4 Ft.
