INSTALLATION INSTRUCTIONS
INTERIOR-MOUNTED VENT MOTOR
Venting Methods
Determine which venting method is best for your application.
Vent system can terminate either through the wall or floor.
Island Location
NOTE: For island locations, a front- or rear-mounted blower
motor can also be mounted for right or left venting if needed for
your application. Most island applications would still require the
venting to be directed down through the floor.
