NOTE: The AFG can be mounted on many other types of louvers, including triangle
vents, round vents, half-round vents, etc. If the vent is smaller than the area of the
fan, we recommend constructing a chamber that surrounds the vent, and then mount
the AFG to the chamber to ensure maximum airflow and performance.
2.1.2 Installing AFG (Attic Fan Gable) Vent Covers
Included with your QuietCool Attic Gable Fan are four vent covers that
are designed to be installed around the attic fan housing to block any air
backdrafting into the attic through a gable vent that is larger than the attic
fan cylinder, causing air to cycle in and out around the vent.
1. Take the vent cover and match it to one of the sides around the attic
fan housing.
2. Using the two provided wood screws, attach each corner to the wood
framing around your gable vent. (See picture for screw locations)
3. Repeat step 1 and 2 for the three additional covers.
READ BEFORE ATTEMPTING TO INSTALL AN AFR OR RM FAN
Getting Started
Always follow Local Building Codes because the fan may require specific fasteners or anchoring systems
not discussed in this installation guide. Installation should be done by a licensed roofing contractor.
Safety Information
Safety precautions should be taken when performing the roofing work described in this installation
guide. You can significantly reduce your risk of danger by following the below recommendations:
• Do not install the fan in wet or windy conditions
• Tie-off both yourself and your equipment when working on steep pitched roofs to avoid falls
• Wear safety glasses and protective gloves when using power tools
• Always wear slip-resistant shoes when working on the roof
• Do not cut through any rafters or structural members of the roof during installation
Ventilation Requirements
If the fan is being installed as an attic fan, in order for it to operate at maximum performance, your
attic must have enough intake ventilation (net free area) to support the amount of air that your fan is
moving. We always recommend 1 SQFT of attic venting per 750 CFM in the system.
