required hardware, one filter, and complete installation
instructions. Replacement Filter Part Number W10177003 is

Calculating Vent System Length
To calculate the length of the system you need, add the equivalent
feet (meters) for each vent piece used in the system.

Example vent system
1- 90° elbow = 5 ft (1.5 m)
8 ft (2.4 m) straight = 8 ft (2.4 m)
1 - wall cap = 0 ft (0 m)
System length = 13 ft (3.9 m)
NOTE: Flexible vent is not recommended. Flexible vent creates
back pressure and air turbulence that greatly reduce performance.
