Odd Mount: The AFG can also be mounted off center for an

odd shaped louver (as shown in Figure 2.1C).

As stated in the note above, any area of the louver that is not

covered by the AFG must be sealed off in order to prevent air

leakage, which may hinder performance.

While this is not the most ideal way to mount the gable fan, it

is possible. However, since the fan is not completely covering

the vent, maximum airflow will not be achieved.

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.

2.2 Installing GA model fans

VERY IMPORTANT: MINIMUM OF 26” CLEARANCE REQUIRED ABOVE CEILING FOR

INSTALLATION OF GA MODEL FANS. ALWAYS FOLLOW LOCAL BUILDING CODES.

1. Determine in which area you would like to install your QuietCool Garage Attic Fan. Now it’s time to find

the exact location using a stud finder. Locate the ceiling studs and mark the location for the fan to

be installed. (see Figure 2.2A) One side of the cut out should be directly next to a wood member for

proper fan mounting and support.

2. When you find the location, mark a 14 1/4” square using a framing square or template. Make sure you

have 2” of clearance all the way around it. The grille that will be installed later is a 16” square. (see

Figure 2.2B)

3. Starting at one corner of the square using a drywall saw, cut out the opening. Remove the drywall

cutout and clear away insulation (if applicable). (see Figure 2.2C)

4. Take the GA fan model into the attic and place it over the ceiling cut out. Attach the fan using screws

into the ceiling joists. (see Figure 2.2D). Install the ceiling grille. (see Figure 2.3H)

VERY IMPORTANT: CHECK TO MAKE SURE FAN BLADE SPINS FREELY AND THE FIRE DAMPER

CLOSES EASILY. MAKE SURE TO SECURE THE LATCH IN THE OPEN POSITION

AVOID BACKDRAFTS: MAKE SURE THE GARAGE FAN WILL NOT BACKDRAFT COMBUSTION

APPLIANCES IN THE GARAGE. QUIETCOOL GARAGE FANS MOVE LARGE QUANTITIES OF AIR.
