Determining
vent length
The maximum length of the exhaust system depends
upon:
• The type of vent (heavy or flexible metal).
• The number of elbows (90 ° turns) used.
• Hood type.
To determine maximum vent length:
1. See the Exhaust Hood Type chart that matches your
type hood for the maximum vent lengths you can use.
Do not use vent runs longer than
specified
in exhaust
vent length chart.
Exhaust systems longer than specified will:
• Shorten the life of the dryer.
• Reduce performance, resulting in longer drying
times and increased energy usage.
2. Determine the number of elbows you will need.
3. In the column listing the type of metal vent you are
using (heavy or flexible), find the maximum length of
metal vent on the same line as the number of elbows.

NOTE: Check periodically to ensure that the outside
exhaust hood is not blocked.
1. Exhaust individual dryers to the central exhaust vent
system with proper sized venting to assure adequate
performance of each dryer. (Dryer has 4-inch exhaust
vent connection.)
2. Install backdraft dampers on each individual dryer
exhaust vent. These dampers may be used for bal-
ancing out the overall vent system. Dampers may be
secured or built locally from a sheet metal fabricator.
NOTE: Check code requirements. Some codes limit or
do not permit installation of clothes dryers in garages,
closets, mobile homes, or sleeping quarters. Contact
your local building inspector.
• Refer to the chart below for recommended installation
requirements. This will ensure you have an adequate
clearance for service and proper operation including
flow of combustion and ventilation air, and that you
have a sufficient distance from combustible
construction.
• Be sure your location allows for a proper exhaust
installation. See "Exhaust requirements."
• Unobstructed air openings are required for coin-
operated stacked dryers when door is installed. Door
must have two centered openings as illustrated. Both
openings must provide a minimum of 72 square inches
of unobstructed airflow.
NOTE: No other fuel-burning appliances may be installed
in the same closet as a dryer.

Multiple
dryer exhausting
guide
Many multiple-family dwellings are furnished with
provisions in the building for washing and drying laundry
with automatic washers and dryers. The exhausting of
the individual clothes dryers can be accomplished with
a central exhaust vent system. The following is a list of
factors for possible consideration
in the design of a
central vent system for this type of installation.
Each room where dryers are located should have
make-up air equal to or greater than the CFM of all
dryers in the room. This dryer requires makeup air of at
least 400 CFM.
This information is intended for general guide purposes
only and does not necessarily include all factors which
may be required for consideration
in a given situation.
If specific information on multiple exhausting is required,
contact a local sheet metal contractor.
