Plan Vent System - Whirlpool 3RLEC8600 Installation Instructions Manual

Hide thumbs


Flexible metal vent must be fully extended and supported when
the dryer is in its final position. Remove excess flexible metal vent
to avoid sagging and kinking that may result in reduced airflow
and poor performance.
An exhaust hood should cap the vent to prevent rodents and
insects from entering the home.
Exhaust hood must be at least 305 mm (12") from the ground
or any object that may be in the path of the exhaust (such as
flowers, rocks, or bushes, etc.).
If using an existing vent system, clean lint from the entire length
of the system and make sure the exhaust hood is not plugged
with lint. Replace any plastic or metal foil vent with rigid metal
or flexible metal vent.

Plan Vent System

Route the Vent
The exhaust outlet is located at the center of the rear of the dryer.
The exhaust vent can be routed up, down, left, right, or straight
out the back of the dryer.
The design of the flue system should ensure that any condensate
formed when operating the appliance from cold, is either retained
and subsequently evaporated or discharged. Following these
installation instructions should adequately meet this requirement.
Vent System Length
1. Select the route that will provide the straightest and most
direct path outdoors. Plan the installation to use the fewest
number of elbows and turns. Avoid making 90° turns. When
using elbows or making turns, allow as much room as
possible. Bend vent gradually to avoid kinking.

A. Good
B. Better
2. Determine vent length.
The maximum length of the exhaust system depends upon:
The type of vent (rigid metal or flexible metal).
The number of elbows used.
Type of hood.
Recommended hood styles
102 mm
102 mm
A. Louvered hood style
B. Box hood style
See the exhaust vent length chart that matches your hood type
for the maximum vent lengths you can use.
Exhaust systems longer than specified will:
Shorten the life of the dryer.
Reduce performance, resulting in longer drying times
and increased energy usage.
3. Determine the number of elbows needed.
NOTE: Do not use vent runs longer than specied in the Vent
Length Chart.
The following chart helps you determine your maximum vent
length based on the number of 90° turns or elbows you will
need and the type of vent (rigid or flexible metal) and hood
that you will use.

NOTE: Side and bottom exhaust installations have a 90º turn

rectangular vent with 2 elbows and a 64 mm (2
is 2.4 m (8 ft.).

(such as multiple unit hookups, plenums, and power-assist fans),
contact your local authorised service company.
