Exhaust requirements
WARNING
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.
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:
•Lint to gather around the dryer where it can be fuel for a fire.
•Moisture damage to woodwork, furniture, paint, wallpaper, carpet, etc.
•Housecleaning problems and health problems.
Dura Safe™ venting products are recommended and are available from your dealer.
Use a heavy metal vent. Do Not use plastic or metal foil vent.
•Do Not use
•Do Not exhaust dryer into a chimney, wall, ceiling, furnace, cold air vent, duct, concealed space, attic or crawl space, or any other vent used for venting.
•Do Not install flexible vent in enclosed walls, ceilings or floors.
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 |
|
rodents and insects from entering |
|
the home. |
|
Exhaust outlet hood must be at |
|
least 12 inches from the ground or |
|
any object that may be in the path |
|
of the exhaust (such as flowers, |
|
rocks or bushes, etc.). | 12" min. |
If using an existing exhaust |
|
system, clean lint from entire |
|
length of system and make sure exhaust hood is not plugged with lint. Replace any plastic or metal foil vent with rigid metal or flexible metal vent.
Use clamps to seal all joints. Do Not use duct tape, screws or other fastening devices that extend into the interior of the vent to secure vent.
Mobile home installation requirements
If codes permit, this appliance is suitable for mobile home installations. The installation of the dryer must conform to Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280 (formerly the Federal Standard for Mobile Homes Construction and Safety, Title 24, HUD Part 280) or latest edition.
The dryer must be exhausted outside.

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. See “Recessed area/closet installation” section, Panel A, for general space requirements.
Typical installations exhaust from the rear of the dryer.

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.
When using elbows or making turns, allow as much room as possible. Bend vent gradually to avoid kinking.
Determine exhaust vent length
The maximum length of the exhaust system depends upon:
•the type of vent (rigid or flexible metal).
•the number of elbows used.
•side or bottom exhaust. Side or bottom exhaust adds a 90° turn inside the dryer. To determine maximum exhaust length, add one 90° turn to the chart.

To convert the dryer, the following kits are available from your dealer:
Exhaust Kit No. 279818 (white)
Exhaust Kit No. 279819 (almond)

Exhaust Kit No. 279969 (silver)
Typical installations for left or right side exhausting.
Typical installations for bottom exhausting.
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.
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.
4.Determine the number of 4" clamps you will need.
