ATTIC AIR INTAKE AND DISCHARGE

Your Whole House Ventilator will be discharging a large volume of air into the attic every minute. Provisions must be made to allow this air to escape to the outside. The sketches below illustrate several different types of exhaust vents that are in common usage. Of these types, the under-eave and gable methods are the most prevalent. Under-eave is probably the most satisfactory from the standpoint of simplicity and economical installation. Make sure under-eave vents are not blocked with ceiling insulation. The fan requires a given amount of exhaust outlet in order to ensure quiet operation and unrestricted air movement. The table below shows the minimum area required for proper operation of fan. Sufficient ventilation is very important. Unless enough is provided, the fan motor will run hot, activating the thermal protector and shutting off the motor. When it cools, it will restart. Such intermittent operation is usually an indication of too little outlet air or too little intake air through the house.
