Determine vent path:

Select route that will provide straightest and most direct  

 

path outdoors.

Plan installation to use fewest number of elbows and turns.

 

When using elbows or making turns, allow as much room  

 

as possible.

Bend vent gradually to avoid kinking.

 

Use as few 90° turns as possible.

 

Determine vent length and elbows needed for best 

drying performance:

Use following Vent system chart to determine type of vent 

 

material and hood combinations acceptable to use.

noTE:

 Do not use vent runs longer than those specified in 

Vent system chart.
Exhaust systems longer than those specified will:

Shorten life of dryer.

 

Reduce performance, resulting in longer drying times    

 

and increased energy usage.

Attach short hose and  

“Y” connector

2. 

If space permits, attach the brass female end of the “Y” 

connector to the cold water faucet. See figure A.

If “Y” connector cannot be attached directly to the cold water 

faucet, the short hose must be used. See figure B. Attach short 

hose to cold water faucet. Screw on coupling by hand until it is 

seated on faucet. Then attach “Y” connector to brass male end 

of the short hose. Screw on coupling by hand until it is seated  

on connector.

CONNECT INLET HOSE

The dryer must be connected to the cold water faucet using  

the new inlet hoses. Do not use old hoses.

Turn cold water off, remove and 

replace rubber washer

1. 

Turn cold water faucet off and remove washer inlet hose.

Check and see if rubber washer is in the “Y” connector. Remove 

old rubber washer from inlet hose and replace with new rubber 

washer provided. 

Connect vent to exhaust hood

2.

Vent must fit over the exhaust hood. Secure vent to exhaust 

hood with 4” (102 mm) clamp. Run vent to dryer location using 

straightest path possible. Avoid 90° turns. Use clamps to seal all 

joints. Do not use duct tape, screws, or other fastening devices 

that extend into interior of vent to secure vent, because they can 

catch lint.

Install exhaust hood

1.

Install exhaust hood and use caulking compound to seal 

exterior wall opening around exhaust hood.

The Vent system chart provides venting requirements that will 

help achieve best drying performance.

noTE:

 Side and bottom exhaust installation have a 90° turn 

inside the dryer. To determine maximum exhaust length, add on 

90° turn to the chart.

noTE: 

If flexible transition vent is used, the length must be 

subtracted from the total exhaust length in the vent system chart.
