Determine vent path
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.
Use the fewest 90° turns possible.
Determine vent length and elbows needed for best drying performance
Use the Vent system chart below to determine type of vent material and hood
combinations acceptable to use.
NOTE: Do not use vent runs longer than those specified in the Vent system chart. Exhaust
systems longer than those specified will:
Shorten the life of the dryer.
Reduce performance, resulting in longer drying times and increased energy usage.
The Vent system chart provides venting requirements that will help to achieve the best drying
performance.
Vent systems charts
When using only one type of metal vent:
Use the following chart to help you determine your maximum vent length based on the
number of 90° turns or elbows you will need and the type of vent (rigid and/or flexible
metal) you will use.
Vent system chart
Number of 90º turns or Rigid metal vent
elbows
0 120 ft (36.6 m)
1 110 ft (33.5 m)
2 100 ft (30.5 m)
3 90 ft (27.4 m)
4 80 ft (24.4 m)
5 70 ft (21.3 m)
When using a combination of rigid and flexible metal vent:
Use the following charts to help you determine your maximum vent length based on the
number of 90° turns or elbows you will need.
Determine the number of elbows or turns you will need.
Determine the length of the fully extended flexible metal vent you will use. Find the
column that has the nearest number of feet to what you will be using.
