EXHAUST SYSTEM REQUIREMENTS
WARNING
This section describes the requirements for a safe and efficient exhaust
system. Failure to follow these instructions can result in poor dryer
performance, damage to the dryer, and a fire hazard.
DUCTING
•
If your current exhaust system is constructed of plastic or metal foil
ß
exible
ducting, replace it with rigid metal ducting.
•
Use only 4” (10.2 cm) diameter rigid metal ducting.
•
When making turns in the ductwork, use 45° elbows rather than 90° elbows. This
provides better air
ß
ow and can reduce the accumulation of lint in the exhaust
system.
90° - Good 45° - Better
