How to calculate the effective duct length
The overall duct length will determine the duct diameter. ^ Measure the actual duct length needed to go from the dryer�s exhaust connection to the vent outlet: 1. Establish the number of elbows or bends necessary, noting the type of bend, angle and radius involved (see Table). 2. Add the additional duct length (as derived by using the values specified in the table) and the actual duct length to get the effective length. Note: Maximum effective duct lengths: 4" (100 mm) diameter 66 ft (20 m) 5" (125 mm) diameter 132 ft (40 m) 6" (150 mm) diameter 328 ft (100 m) Using the ring adapter up to an effective duct length of 33 ft (10 m) and a standard duct diameter of 4" (100 mm) will provide optimal drying times and energy consumption. Do not use the ring adapter if the effective duct length is more than 33 ft (10 m). Effective duct lengths over 66 ft (20 m) require a larger duct diameter. Longer ducts may lead to slight decreases in dryer efficiency if the necessary duct diameter is not employed.

Tips about the ductwork
� Check with your local building code to determine the maximum allowable duct length. � Use flexible metal pipe or rigid metal pipe for venting. Non-metallic flexible hose should not be used, it is a potential fire hazard. � For best drying results avoid extra long ducting with too many bends, angles or tight corners. � The shorter the exhaust ductwork, the more efficient the dryer will be. Expelled air is slowed down in the ducts due to friction against the inner walls. The shorter and smoother the inner walls are, the less friction will be created. � An elbow or bend creates more friction than a straight duct. An additional duct length factor must be added for each elbow or bend (see Table). This factor expresses the resistance of the bend in terms of a straight length of duct. The additional length factor is then added to the existing duct to give the effective length. A larger duct diameter helps reduce friction. Therefore the duct diameter and length should be increased simultaneously.
