When installing a dryer, there are several things to be mindful of before tossing in your first damp load of laundry. Generally, a good rule of thumb is to have between 5 and 6 inches of clearance between the dryer and the wall. In the case that your dryer wobbles when doing a load, this prevents it from ramming into its surroundings and causing damage. Additionally, the dryer hose needs the extra room to ventilate properly. This can lead to some pretty major consequences if not installed properly.
