FOR COMPLETE INFORMATION, SEE INSTALLATION INSTRUCTIONS PACKED 
WITH YOUR DRYER.
DUCTING MATERIALS: 
For best performance, this dryer should be vented with 4" diameter all rigid metal exhaust 
duct. If rigid metal duct cannot be used, then UL-listed flexible metal (semi-rigid) ducting can 
be used (Kit WX08X10077). 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. Please see installation instruction packed with your dryer 
for complete instructions when using flexible metal (foil type) ducting. 
EXHAUST LENGTH CALCULATION: 
1. Determine the number of 90° turns needed for your installation. If you exhaust to the side 
or bottom of dryer, add one turn.
2.  The maximum length of 4" rigid (aluminum or galvanized) duct which can be tolerated 
is shown in the table. A turn of 45° or less may be ignored. Two 45° turns within the duct 
length should be treated as a 90° elbow. A turn over 45° should be treated as a 90° elbow.
Dryers must be exhausted to the outside.
CAUTION: For personal safety do not terminate exhaust into a chimney, under any enclosed 
house floor (crawl space), or into an attic, since the accumulated lint could create a fire hazard 
or moisture could cause damage. Never terminate the exhaust into a common duct or plenum 
with a kitchen exhaust, since the combination of lint and grease could create a fire hazard.
Exhaust ducts should be terminated in a dampered wall cap to prevent back drafts, bird 
nesting, etc. The wall cap must also be located at least 12" above the ground or any other 
obstruction with the opening pointed down.

For every extra 90° elbow, reduce the allowable vent system 
length by 10 ft.
Two 45° elbows will be treated like one 90° elbow. 
For the side exhaust installations, add one 90° elbow to the chart. 
When calculating the total vent system length, you must add all 
the straight portions and elbows of the system (including the 
transition duct.
