2. Single Dryer Venting
When possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should
be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns
as possible. It is suggested that the use of 90° turns in the ducting
be avoided; use 30° and/or 45° angles
instead.
Horizontal Venting:
When horizontal dryer venting is used, the length of the ductwork from the dryer to the outside exhaust
outlet, must not exceed 15 feet (4.6 meters). The minimum diameter of this ductwork must be at least
10-inches (25.4 cm). Including basket (tumbler)/dryer elbow connections or elbows used for outside
protection from the weather, no more than one (1) elbow should be used in the exhaust duct run. If more
than one (1) elbow is used, the cross-sectional area of the ductwork must be increased.
Vertical Venting:
When vertical dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet,
must not exceed 20 feet (6.1 meters). The minimum diameter of this ductwork must be at least
12-inches (30.48 cm) even though the dryer exhaust duct connection is only 10-inches (25.4 cm). Including
basket (tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more
than three (3) elbows should be used in the exhaust duct run. If more than three (3) elbows is used, the
cross-sectional area of the ductwork must be increased.
