DRYER VENTING REQUIREMENTS
WARNING: To reduce the risk of fire, this dryer MUST BE 
EXHAUSTED OUTDOORS.
IMPORTANT: Observe all governing codes and ordinances.
Dryer exhaust must not be connected into any gas vent, 
chimney, wall, ceiling, attic, crawlspace, or a concealed space 
of a building. Only rigid or flexible metal vent shall be used for 
exhausting.
 
Only a 4" (102 mm) heavy, metal exhaust vent and clamps 
may be used. 
 
Do not use plastic or metal foil vent.
Rigid metal vent:
 
Recommended for best drying performance and to avoid 
crushing and kinking.
Flexible metal vent: (Acceptable only if accessible to clean)
 
Must be fully extended and supported in final dryer location.
 
Remove excess to avoid sagging and kinking that may result 
in reduced airflow and poor performance.
 
Do not install in enclosed walls, ceilings, or floors.
 
The total length should not exceed 7
3
4
 ft. (2.4 m).
NOTE: If using an existing vent system, clean lint from entire 
length of the system and make sure exhaust hood is not 
plugged with lint. Replace plastic or metal foil vents with rigid 
metal or flexible metal vents. Review “Vent System Chart” and, 
if necessary, modify existing vent system to achieve best drying 
performance.
