A:Answer Hi Fred. To ensure sufficient clearance for water inlet hoses, drain hose and airflow, for the ENERGY STAR® Qualified LG Single Unit Front Load LG WashTower™ with Center Control™ 4.5 cu. ft. Washer and 7.4 cu. ft. Electric Dryer, Model # WKE100HVA you need to allow minimum clearances of at least 1'' (2.5 cm) at the sides and 4'' (10 cm) behind the appliance. Be sure to allow for wall, door, or floor moldings that may increase the required clearances...^Ivan
