Exhaust system requirements, continued

- FIRE HAZARD - A clothes dryer must be

exhausted outdoors. Do not exhaust dryer into a chimney, a

wall, a ceiling, an attic, a crawl space or any concealed space

of a building. A clothes dryer produces combustible lint. If

the dryer is not exhausted outdoors, some ﬁ ne lint will be

expelled into the laundry area. An accumulation of lint in any

area of the home can create a health and ﬁ re hazard.

The dryer must be connected to an exhaust outdoors.

Regularly inspect the outdoor exhaust opening and remove

any accumulation of lint around the outdoor exhaust opening

and in the surrounding area.

- FIRE HAZARD -

•

Do not allow combustible materials (for example: clothing,

draperies/curtains, paper) to come in contact with exhaust

system. The dryer MUST NOT be exhausted into a chim-

ney, a wall, a ceiling, or any concealed space of a building

which can accumulate lint, resulting in a ﬁ re hazard.

•

Do not screen the exhaust ends of the vent system, or use

any screws, rivets or other fasteners that extend into the

duct to assemble the exhaust system. Lint can become

caught in the screen, on the screws or rivets, clogging the

duct work and creating a ﬁ re hazard as well as increasing

drying times. Use an approved vent hood to terminate the

duct outdoors, and seal all joints with duct tape. All male

duct pipe ﬁ ttings MUST be installed downstream with the

ﬂ ow of air.

- FIRE HAZARD - Exceeding the length of

duct pipe or number of elbows allowed in the "MAXIMUM

LENGTH" charts can cause an accumulation of lint in the ex-

haust system. Plugging the system could create a ﬁ re hazard,

as well as increase drying times.

CORRECT

In installations where the exhaust system is not described in

the charts, the following method must be used to determine

if the exhaust system is acceptable:

1. Connect an inclined or digital manometer between the

dryer and the point the exhaust connects to the dryer.

2. Set the dryer timer and temperature to air ﬂ uff (cool

down) and start the dryer.

3. Read the measurement on the manometer.

4. The system back pressure MUST NOT be higher than

0.75 inches of water column. If the system back pressure

is less than 0.75 inches of water column, the system is

acceptable. If the manometer reading is higher than .075

inches of water column, the system is too restrictive and

the installation is unacceptable.

Although vertical orientation of the exhaust system is

acceptable, certain extenuating circumstances could affect

the performance of the dryer:

•

Only the rigid metal duct work should be used.

•

Venting vertically through a roof may expose the exhaust

system to down drafts causing an increase in vent

restriction.

•

Running the exhaust system through an uninsulated area

may cause condensation and faster accumulation of lint.

•

Compression or crimping of the exhaust system will cause

an increase in vent restriction.

•

The exhaust system should be inspected and cleaned a

minimum of every 18 months with normal usage. The

more the dryer is used, the more often you should check

the exhaust system and vent hood for proper operation.
