A:Answer Hello there. We understand your inquiry about the ventilation requirements for the LG WashTower in your closet installation. While the unit's dryer is vented, a closet installation requires sufficient airflow to the washer and dryer to operate correctly. The owner's manual for this unit specifies that "louvered doors with equivalent ventilation openings are also acceptable" for this type of installation.
Even with a direct vent to the outside, a louvered door is needed to allow for proper air intake and to prevent heat and moisture from building up inside the closet, which could affect the performance of the unit.
