Exhaust Requirements for Gas and Electric Dryers
Do Not use nonmetal, flexible duct. Do Not use metal duct smaller that four inches in diameter. Do
Not use exhaust hoods with magnetic latches. Improper air supply for exhausting may result in a
fire. Check that exhaust system is not longer than specified. Exhaust systems longer than specified
will:
•
Accumulate lint
•
Shorten the life of the product
•
Reduce performance and result in longer drying times and increased energy usage.
Failure to follow these specifications may result in a fire.
Do Not exhaust dryer into a chimney, furnace cold air duct, attic or crawl space, or any other duct
used for venting. Clean the exhaust system every other year. Do Not install flexible duct under
wall, ceiling or floor materials. Accumulated lint could result in a fire or cause moisture damage.
Four inch Rigid Metal Duct is preferred. Four-inch flexible metal duct may be used.
Metal flexible duct must be fully extended and supported when the dryer is in its final position. DO
NOT KINK OR CRUSH THE DUCT. The metal flexible duct must be completely open to allow adequate
exhaust air to flow.
Plan installation to use the fewest number of elbows and turns. Allow as much room as possible when
using elbows or making turns. Bend duct gradually to avoid kinking. Remove excess flexible duct to
avoid sagging and kinking that may result in reduced air flow.
Use duct tape to seal all joints.
The Exhaust duct can be routed down, left, right, or straight out the back of the dryer. Space
requirements are provided in the Installation Instructions.
Minimum length of rear exhaust system depends upon the type of duct used, number of elbows and
the type of exhaust hood. The maximum length for both rigid and flexible ducts is shown in chart.
Side or bottom exhaust maximum length is 16 feet with two external elbows.
Exhausting the dryer outside is preferred.
Four inch Rigid Metal Duct is preferred. Four-inch flexible metal duct may be used.
Metal flexible duct must be fully extended and supported when the dryer is in its final position. DO
NOT KINK OR CRUSH THE DUCT. The metal flexible duct must be completely open to allow adequate
exhaust air to flow.
