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.
