Part 8 EXHAUST REQUIREMENTS AND MAINTENANCE

Following are important instructions and information concerning the exhaust requirements for your dryer.

!Important Warning: To reduce the risk of fire, combustion, or accumulation of combustible gases, DO NOT exhaust dryer air into an enclosed and unventilated area, such as an attic, wall, ceiling, crawl space, chimney, gas vent, or concealed space of a building. To reduce the risk of fire, DO NOT exhaust the dryer with plastic or thin foil ducting.

NOTE : Deduct 6 feet (1.8 m) for each additional elbow.

It is not recommended to use more than 4 90° elbows.

Exhaust Requirements and Instructions:

1.Venting materials are not provided with the dryer and you should obtain the necessary venting materials locally. For example, the outer end of exhaust pipe must have a weather hood with hinged dampers to prevent back-draft when the dryer is not in use.

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. Non-combustible flexible metal duct is acceptable. Do not use plastic or thin foil ducting.

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.
