1 Introduction
1.1 Product Description
This product is specifically designed to assist a single residen-
tial dryer (gas or electric) in overcoming dryer performance loss
caused by long or restrictive duct systems. Dryer Exhaust Duct
Power Ventilators (DEDPVs) are different from the term dryer
booster because this product has to comply with strict safety
requirements.
This product works together with the application’s dryer. It may
be installed in a different location than the dryer, such as an at-
tic, a crawl space, or a basement.
This dryer depends on this product to safely and efficiently op-
erate. Operating this dryer without a functional product will
cause unsatisfactory dryer operation and too much energy con-
sumption, and possibly a dryer fire. See the warning on the in-
dicator panel.
In order to perform recommended maintenance, product loca-
tion should allow sufficient access for service. Refer to section
3.2.3 To Install the Ducts.
This fan has rotating parts and personnel must exercise safety
precautions during installation, operations, and maintenance.

3 Installation
3.1 To Do Before the Installation
Caution
This is a cord-connected product. Do not
try to field wire the product. Tampering with
the electrical enclosure voids the UL mark-
ing and the manufacturer’s warranty.
3.1.1 To Calculate the Duct Run
This product is able to overcome equivalent duct lengths up to 125 feet (38 meters) on duct systems with 4 inch (102mm) diameter
galvanized, steel ducts. It is also able to hold an air velocity of 1200 fpm (6.10 m/s).
To calculate the length of your planned duct system, measure from the dryer to the external release point in the roof or the wall. For
each 45° elbow, add 2–1/2 feet (0.76 meters) to your total duct system calculations. Add 5 feet (1.5 meters) for every 90° elbow.
Use the table below to determine the length of duct this product can be used with at specified elevations:
Elevation in feet (meters) Maximum Equivalent Duct length in feet (meters)
Sea Level 125 (38)
2000 (610) 114 (35)
4000 (1219) 106 (32)
6000 (1829) 98 (30)
8000 (2438) 92 (28)
