2.The exhaust duct must be four inches (10.2 cm) in diameter with no obstructions. The exhaust duct should be kept as short as possible. Make sure to clean any old ducts before installing your new dryer.
3.Rigid metal duct is recommended. Do not install flexible duct in concealed spaces.
4.DO NOT use sheet metal screws on exhaust pipe joints or other fastening means which extend into the duct that could catch lint and reduce the efficiency of the exhaust system. Secure all joints with duct tape.
5.To maximize operating results, please observe the duct length limitations noted in the chart above.
