3. 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 should be sealed off to prevent air
leakage.
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.
1.
Determine which ceiling 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
.
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 HAS ENOUGH CONTINUOUS INLET
VENTING (AS SHOWN IN SECTION 1.4) TO AVOID BACKDRAFTING COMBUSTION APPLIANCES
IN THE GARAGE.
