The Qmark / Marley ASRV14 attic fan is an economical house fan. It should be installed as close to the center of the roof ridgeline as possible on the rear slope of the roof, with uppermost portion of ventilator dome just below ridge level. 

Make sure that the ASRV14 Attic Fan has sufficient intake area in the attic to assure that the fan will not be overloaded and that it will deliver its rated CFM. This can be accomplished with some type of attic venting such as gable louvers or under eave vents.
