Dryer Exhausting Information – Metal Duct Only
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.
The total vent system length includes all the straight portions and elbows of the system (transition
duct included).
Laundry Center length includes factory-installed elbow that does not impact vent length.
