While many factors can affect how long your fan will last, this GAF Master Flow Powered Ventilation Products Limited Warranty covers your Fan in the unlikely event that it contains a manufacturing defect.
Proper attic ventilation consists of a balance between air intake at or near the soffits and air exhaust at or near your roof ridge. The Federal Housing Administration recommends a minimum of at least 1 square foot of attic ventilation evenly split between intake and exhaust for every 300 square feet of attic floor space.
1,450 CFM airflow with thermostat helps exhaust heat and moisture from up to 2,300 sq. ft. of attic space.

The fan should be based on the attic square footage and amount of NFA Intake:
1600 sq. ft. or less - ERV4 - 1000 CFM
2200 sq. ft. or less - ERV5 - 1250 CFM
2800 sq. ft. or less - ERV6 - 1500 CFM
2300 sq. ft. or less - EGV5 - 1450 CFM
3000 sq. ft. or less - EGV6 - 1600 CFM
It is recommended to use 14 gauge wire under 50 ft. and to use 12 gauge wire over 50 ft.
Always check and follow local or state building codes.
CFM = Cubic Feet per Minute. In this case, it is the cubic feet of air that a fan will move in one minute.
NFA - Net Free Area. This is the actual open area of a vent which will allow air passage.
No, the fan is designed to be installed on an Asphalt Shingled roof, with a pitch between 3:12 and 12:12.
Master Flow® Replacement Motors, along with some available parts, can be purchased through Home Depot.
Some vibration may be caused by oversizing of attic fans. These would seem to "bounce" on the roof. Not having the required nails may also cause vibrations. There should ba a nail every 4" on the perimeter of the flashing. A damaged blade may result in an imbalance, thus promoting vibrations.
Master Flow® fans do not have a battery. These only work in direct sunlight.
Master Flow® need a copy of the receipt/serial number along with the homeowner's information and a description of the issue to start the warranty process. Send this information to warrantyllbp@gaf.com or mail to:
