Part 8 EXHAUST REQUIREMENTS AND MAINTENANCE

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

!Warning: 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. Failure to do so can result in death, explosion, or fire.

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 or semi-rigid metal ducting is recommended for use as transition ducting between the dryer and and the wall. In special installations when it is impossible to make a connection with the above recommendations, then a UL-listed flexible metal transition duct may be used between the dryer and wall connection only. The use of this ducting will affect dry time.

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.
