DNCD450EA/GA – GE Super 7.0 Cu. Ft. Capacity Commercial Dryer
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 “all rigid metal”
duct cannot be used, then “flexible all metal” venting can be used, but it will reduce the maximum recommended
duct length.
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.
The maximum length for flexible ducts are less than for rigid duct.
2. 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.
Exhausting the dryer to the outside is strongly recommended to prevent large amounts of moisture and lint
from being blown into the room. Gas dryers or any dryer located in a closet 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.
Other terminations, such as louvered wall boxes, are acceptable provided they are equivalent to a 4" opening
dampered wall cap.
