The ductwork 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. Single or independent dryer venting 

is recommended. It is suggested that the use of 90° turns be 

avoided; use 30° and/or 45° bends instead. The radius of the 

elbows should preferably be 1-1/2 times the diameter of the 

duct. All ductwork should be smooth inside with no projections 

from sheet metal screws or other obstructions, which will collect 

lint. When adding ducts, overlap the duct being connected. 

All ductwork joints must be taped to prevent moisture and lint 

from escaping into the building. Inspection doors should be 

installed at strategic points in the exhaust ductwork for periodic 

inspection and cleaning of lint from the ductwork.

IMPORTANT:

 Exhaust back pressure measured by a 

manometer/magnehelic in the exhaust duct must be no less 

than 0 and must not exceed 0.3 in WC (0.75 mb).

NOTE:

 It is recommended that exhaust or booster fans not be 

used in the exhaust ductwork system except where necessary 

to maintain exhaust back pressure (in the exhaust duct) between 

zero and 0.3" water column. Where employed, booster fans 

must not activate the dryer airflow proving switch (sail switch) 

when the dryer is not in operation.

NOTE:

 When the exhaust ductwork passes through a wall, 

ceiling, or roof made of combustible materials, the opening must 

be 2" (5.08 cm) larger than the duct (all the way around). The 

duct must be centered within this opening.
The ductwork for this dryer must be suitable for the appliance 

category in accordance with national installation regulations of 

the country of destination.

Outside Ductwork Protection

To protect the outside end of the horizontal ductwork from the 

weather, a 90° elbow bent downward should be installed where 

the exhaust exits the building. If the ductwork travels vertically 

up through the roof, it should be protected from the weather by 

using a 180° turn to point the opening downward. In either case, 

allow at least twice the diameter of the duct between the duct 

opening and the nearest obstruction (refer to the diagram).

IMPORTANT:

 Do not use screens, louvers, or caps on the 

outside opening of the exhaust ductwork.

Single Dryer Venting (8

"

 Duct)

IMPORTANT:

 A minimum exhaust duct size of 8" (20.3 cm) 

must be used.
For an 8" (20.3 cm) run where a maximum of two elbows are 

used (refer to the illustration below), the ductwork from the dryer 

outlet must not exceed 10' (3.0 m).
This calculation of 10' (3.0 m) compensates or allows for the use 

of a maximum of two elbows. Refer to the illustration below.

If the length of the duct run or quantity of elbows used exceeds 

the above noted specifications, the cross-sectional area of the 

ductwork may need to be increased.

IMPORTANT:

 For extended ductwork runs, the cross section 

area of the ductwork can only be increased to an extent. When 

the ductwork approaches the maximum limits noted in this 

manual, a professional HVAC firm should be consulted for 

proper venting information.

Single Dryer Venting (10

"

 Duct)

IMPORTANT:

 A minimum exhaust duct size of 10" (25.4 cm) 

must be used for extended runs.
For a 10" (25.4 cm) run where a maximum of two elbows are 

used (refer to the illustration below), the ductwork from the dryer 

outlet must not exceed 45' (13.7 m).
This calculation of 45' (13.7 m) compensates or allows for the 

use of a maximum of two elbows. Refer to the illustration below.

If the length of the duct run or quantity of elbows used exceeds 

the above noted specifications, the cross-sectional area of the 

ductwork may need to be increased.

IMPORTANT:

 For extended ductwork runs, the cross section 

area of the ductwork can only be increased to an extent. When 

the ductwork approaches the maximum limits noted in this 

manual, a professional HVAC firm should be consulted for 

proper venting information.

Multiple Dryer (Common) Venting

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 10" (25.4 cm) 

duct (when dryer common exhaust is used) is added.

IMPORTANT:

 No more than four dryers or eight tumblers total 

should be connected to one main common duct.
The main duct may be any shape provided that the minimum 

cross-sectional area is maintained. The illustration below shows 

the minimum cross-sectional area for multiple dryer venting. 

These figures must be increased if the main duct run from the 

last dryer to where it exhausts to the outdoors is unusually long 

(over 30' [9.1 m]) or has numerous elbows (more than one) in it.
