    Solar Options For Your Attic Ventilation

    Solar Powered Attic Ventilation - Pittsburgh Today - Live KDKA TV

  • Effective attic ventilation requires air to exit at or near the peak of the roof and replacement air to be drawn in under the eaves of the house, via soffit venting. The Home Ventilating Institute (HVI) recommends that powered attic ventilators provide at least 10 air changes per hour to equalize attic temperature.

    I just replaced the motor on my 355F unit, rewiring the same way I removed the old. Now the fan does come on. I have thermostat set for 90 and its well over that today. All was working prior to replacement and the new motor was tested prior to installation.

    I installed this attic fan along with the Broan 72v speed controller, at slower speeds does the motor consume less wattage?

    The original box was damaged in shipping and repackaged. As a result, I do not have a template to use for installation. Is there one I can download or get the size of the hole that needs to be cut in the roof?
