Ducting Materials: For best performance, this dryer
should be vented with 4” diameter all-rigid metal
exhaust duct.
Exhaust Length Calculation:
1. Determine the number of 90º turns needed for
your installation.
2. The maximum length of 4’ rigid (aluminum or
galvanized) duct which can be tolerated is shown
in the table.
A turn of 45º or less may be ignored. Two 45º
turns within the duct length should be treated
as a 90º elbow.
A turn over 45º should be treated as a 90º elbow.
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.
Other terminations, such as louvered wall boxes,
are acceptable provided they are equivalent to
a 4” opening dampered wall cap.
For more information on venting kits and
accessories, please call 1.800.GE.CARES.
