Loading and using the Dryer.
Venting the Dryer
For the best drying performance, the dryer needs to be properly vented. The dryer will use more energy
and run longer if it is not vented to the specifications below. Carefully follow the details on Exhausting in the
Installation Instructions.
Use only rigid metal 4" diameter ductwork inside the
dryer cabinet. Use only rigid metal or UL approved
flexible metal 4" diameter ductwork for exhausting
to the outside.
Do not use plastic or other combustible ductwork.
Use the shortest length possible.
Do not crush or collapse ductwork.
Avoid resting the duct on sharp objects.
Venting must conform to local building codes.
