NOTE 1
Opening must be 2-inches (5.08 cm) larger than the duct (all the
way around). The duct must be centered within this opening.
NOTE 2
Distance should be 2 times the diameter of the duct to the nearest
obstruction.
Multiple Dryer (Common) Venting
IMPORTANT:
For extended ductwork runs, the cross-
sectional area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
If it is not feasible to provide separate exhaust ducts for each
dryer, ducts from individual dryers may be channeled into a
“common main duct.” The individual ducts should enter the
bottom or side of the main duct at an angle not more than
45° in the direction of airflow. The main duct should be
tapered, with the diameter increasing before each individual
duct is added. The minimum diameter of the individual
ductwork must be at least 16-inches (40.64 cm).
IMPORTANT:
No more than 4 dryers should be connected
to 1 main common duct.
The illustration below shows the minimum cross-sectional
area for multiple dryer round or square venting. These figures
must be increased if the main duct run from the last dryer to
where it exhausts to the outdoors is longer than 20 feet (6.096
meters) or has more than 1 elbow in it.

Electrical Information _________________
Electrical Requirements
All electrical connections must be made by a properly
licensed and competent electrician. This is to ensure that
the electrical installation is adequate and conforms to local
and state regulations or codes. In the absence of such
codes, all electrical connections, materials, and
workmanship must conform to the applicable requirements
of the National Electrical Code ANSI/NFPA NO. 70-LATEST
EDITION or in Canada, the Canadian Electrical Codes Parts
1 & 2 CSA C22.1-1990 or LATEST EDITION.
For personal safety, the dryer, when installed must be
electrically grounded in accordance with local codes or, in
the absence of local codes, with the National Electrical
Code, ANSI/NFPA 70, or the Canadian Electrical Code, CSA
C22.1.
IMPORTANT:
Failure to comply with these codes or
ordinances, and/or the requirements stipulated in this
manual can result in personal injury or component failure.
NOTE:
Component failure due to improper installation will
void the warranty.
Each dryer should be connected to an independently
protected branch circuit. The dryer must be connected with
copper wire only. Do not use aluminum wire, which could
cause a fire hazard. The copper conductor wire/cable must
be of proper ampacity and insulation in accordance with
electric codes for making all service connections.
NOTE:
The use of aluminum wire will void the warranty.
An individual ground circuit must be provided to each
dryer, do not daisy chain.
Component failure due to improper voltage application will
void the warranty.
The manufacturer reserves the right to make changes in
specifications at any time without notice or obligation.
Wiring diagrams are affixed to the inside at the top front
control door and the rear upper back guard/panel.
IMPORTANT:
A separate protected circuit must be
provided to each dryer.
The dryer must be connected to the electric supply shown
on the data label. The supply voltage must match the
electric service specifications of the data label exactly.
The wire size must be properly sized to handle the related
current.
A = 16-inches (40.64 cm)
B = 20 feet (6.096 meters)
!
WARNING
208 VAC and 240 VAC are not the same. Any damage
done to dryer components due to improper voltage
connections will automatically void the warranty.
