WARNING
USE ONLY METAL DUCT 4
″ DIAMETER (102 mm
FOR CANADA). DO NOT USE DUCT LONGER THAN
SPECIFIED IN THE EXHAUST LENGTH TABLE.
Dryer Exhausting Information—Metal Duct Only
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.
