EXHAUSTING THE DRYER (cont.)
Installation Instructions
CONNECTING THE DRYER TO HOUSE 
VENT
RIGID METAL TRANSITION DUCT
•
  For best drying performance, a rigid metal transition 
duct is recommended.
•
  Rigid metal transition ducts reduce the risk of crushing 
and kinking.
UL-LISTED FLEXIBLE METAL (SEMI-RIGID) TRANSITION 
DUCT
•
  If rigid metal duct cannot be used, then UL-listed 
flexible metal (semi-rigid) ducting can be used (Kit 
PM08X10085).
•
  Never install flexible metal duct in walls, ceilings, floors 
or other enclosed spaces.
•
  Total length of flexible metal duct should not exceed 7’ 
9” (2.4 m).
•
  For many applications, installing elbows at both 
the dryer and the wall is highly recommended (see 
illustrations at right). Elbows allow the dryer to sit 
close to the wall without kinking and/or crushing the 
transition duct, maximizing drying performance.
•
  Avoid resting the duct on sharp objects.
UL-LISTED FLEXIBLE METAL (FOIL-TYPE) TRANSITION 
DUCT
•
  In special installations, it may be necessary to connect 
the dryer to the house vent using a flexible metal 
(foil-type) duct. A UL-listed flexible metal (foil-type) duct 
may be used ONLY in installations where rigid metal or 
flexible metal (semi-rigid) ducting cannot be used AND 
where a 4
”
 diameter can be maintained throughout 
the entire length of the transition duct.
•
  In Canada and the United States, only the flexible 
metal (foil-type) ducts that comply with the “Outline for 
Clothes Dryer Transition Duct Subject 2158A” shall be 
used.
•
  Never install flexible metal duct in walls, ceilings, floors 
or other enclosed spaces.
•
  Total length of flexible metal duct should not exceed 7’ 
9” (2.4 m).
•
  Avoid resting the duct on sharp objects.
•
  For best drying performance:
  1. Slide one end of the duct over the clothes dryer 
outlet pipe.
  2. Secure the duct with a clamp.
  3. With the dryer in its permanent position, extend 
the duct to its full length. Allow 2
”
 of duct to 
overlap the exhaust pipe. Cut off and remove 
excess duct. Keep the duct as straight as 
possible for maximum airflow.
  4. Secure the duct to the exhaust pipe with the 
other clamp.
FOR TRANSITION VENTING (DRYER TO 
WALL), DO
:
• DO cut duct as 
short as possible 
and install 
straight into wall.
•
 DO use elbows 
when turns are 
necessary.
DO NOT:
Elbows
• DO NOT bend or 
collapse ducting. 
Use elbows 
if turns are 
necessary.
•
 DO NOT use 
excessive 
exhaust length. 
Cut duct as short 
as possible.
• DO NOT crush 
duct against the 
wall.
•
 DO NOT set 
dryer on duct.
