lired.

Metal flexible vent

must be fully

extended

and supported

when the

dryer is in its final position. DO NOT

KINK OR CRUSH THE VENT. The metal

flexible

vent must be completely

open to allow adequate

exhaust

air

to flow.

Allow as much room as possible

when

using elbows

or making

turns.

Bend vent gradually

to avoid

kinking.

Remove

excess flexible

vent to avoid

sagging

and kinking that may result in

reduced

Service

Manual,

"Exhausting

Whirlpool

Dryers," Part No. 603197,

available

from your Whirlpool

parts

distributor.

Service

check:

The back pressure in

any exhaust

system must not exceed

0.6 inches of water

column

measured

with an inclined

manometer

at the

point that the exhaust

vent connects

to the dryer.

Exhausting

the electric

dryer outside

is recommended.

A closet installation

must be exhausted

outside. Recessed

installation

that is not exhausted

outside

must use Exhaust Deflector,

Part No. 3391278 (electric

dryer only),

available

from your dealer.

If dryer is installed

in a confined

area,

such as a bedroom,

bathroom

closet, it must be exhausted

to the

outside

and provision

made

for

enough

air for combustion

and

ventilation.

(Check

governing

codes

and ordinances.)

See "Recessed

area and closet installation

instructions"

on Page 11.

An exhaust

hood should cap the

exhaust

vent to prevent

exhausted

air

from returning

into the dryer. The

outlet of the hood must be at least

12 inches from the ground

anything

else that may be in the path

of the exhaust.

Four-inch

outlet hood is preferred.

However,

a 2-l/2-inch

outlet exhaust

hood may be used. A 2-l/2-inch

outlet creates

greater

back pressure

than other hood types. For

permanent

installation,

a stationary

exhaust

system is required.

A main exhaust

vent can be used for

exhausting

a group of dryers. Main

exhaust

vent should be sized to

remove

200 CFM of air per dryer.

Large-capacity

lint screens of proper

design

may be used in the main

exhaust

vent if checked

and

cleaned

frequently.

The room where

the dryers are located

should have

make-up

air equal

to or greater

than

the CFM of all the dryers in the room.

Back-draft

Damper

Kits, Part No.

3391910, are available

from your

Whirlpool

dealer

and should be

installed

in each

dryer's exhaust

vent

to prevent

exhausted

air from

returning

into the dryers and to keep

the exhaust

in balance

within the

main exhaust

vent. Unobstructed

air

openings

are required.
