About 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 below specifications.
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 listed 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.
Avoid resting the duct on sharp objects.
Venting must conform to local building codes.
