Fire Hazard

Use a heavy metal vent. Do not use a plastic vent. Do not use a metal foil vent.

Failure to do so can result in death or fire.

l Do Not use non-metal flexible vent, metal vent that is smaller than four inches

(10.2 cm) in diameter or exhaust hoods with magnetic latches.

l	Do	Not	exhaust		dryer	into	a	chimney,
	furnace		cold	air	vent,	attic	or	crawl space,
	or	any	other	vent	used	for	venting.
l	Do	Not	install	flexible		vent	in	enclosed
	walls,		ceilings	or	floors.

Important: Observe all governing codes and ordinances.

It is recommended that you exhaust your dryer to the outside for best performance. Moisture and lint indoors may cause:

l Lint to gather around the dryer where it can be fuel for a fire.

l Moisture damage to woodwork, furniture, paint, wallpaper, carpet, etc.

l Housecleaning problems and health problems.

Four-inch (10.2 cm) diameter vent is required for best performance.

Rigid or flexible metal exhaust vent must be

used. Do Not use plastic or foil-covered vent. Rigid metal vent is recommended to prevent crushing and kinking.

Flexible metal vent must be fully extended and supported when the dryer is in its final position. Remove excess flexible vent to avoid sagging and kinking that may result in reduced air flow.

An exhaust hood should cap

the exhaust vent to prevent

exhausted

air

from

returning

to the

dryer.

at least 12 inches (30.5 cm)

(such

Mobile homeinstallation requirements

Four-wire power supply cord or cable must be used in a mobile home installation.

The dryer must be exhausted outside.

I$- outside

If dryer is exhausted through the floor and the area under the mobile home is enclosed, the exhaust system must terminate outside. Extension beyond the enclosure is

recommended to prevent lint and moisture buildup under the mobile home.

Plan the exhaust vent installation

Route the vent

The exhaust outlet is located at the center of the rear of the dryer.

The exhaust vent can be routed up, down, left, right or straight out the back of the dryer.

Determine vent length

The maximum length of the exhaust system depends upon:

-the type of vent (rigid or flexible metal)

-the number of elbows used.

1.See the exhaust vent length 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 charts.

Exhaust systems longer than specified will:

-Accumulate lint creating a potential fire hazard.

-Shorten the life of the dryer.

-Reduce performance, resulting in longer drying times and increased energy usage.

Select the route that will provide the

straightest and most direct path outdoors.

Plan the installation to use the fewest number of elbows and turns. Avoid making 90” turns.

When using elbows or making turns, allow as much room as possible. Bend vent gradually to avoid kinking.

1)2. Determine the number of elbows you will need.

3.In the column listing the type of metal vent you are using (rigid or flexible), find the maximum length of metal vent on the same line as the number of elbows.

The maximum length using a 2” x 6” (5.1 cm x 15.2 cm) rectan ular vent with 2 elbows and a 2-l/2” (6.4 cm) ex7l aust hood is 8 ft (244 cm).

For exhaust systems not covered by exhaust vent length charts check with your dealer or distributor for information.
