Hi BooBooBear- This is Sue at GE Appliances. Thanks for choosing our GE® 7.2 cu. ft. capacity aluminized alloy drum electric dryer GTD42EASJWW! The minimum clearances other than alcove or closet installation are 0" both sides;1" rear. We suggest to view the Quick Specs at the following link: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=GTD42EASJ_c3.pdf - Also, this model features Auto Dry- For clothes that come out feeling and looking great, this setting monitors air temperature to set the optimal drying time and designed to help prevent clothes from over drying. By continually sensing the temperatures of the air in the dryer drum, the thermostat controls the heat source (heater coils) and the advancement of the dryer timer. When the laundry is wet, the air is cool in the dryer. As the load begins to dry and the drum air is warm, the heat turns off. As the air cools, the control activates the heat to come on again. This off and on cycling may happen a number of times (depending on the fabric, load size, and cycle selector setting). The cycle selector advances (when the heat is off) until it automatically turns off dryer. Since there are many variables, we cannot provide actual dry times. Keep in touch!
