For maximum cooling, it is most efficient to
have the blades 8 to 9 feet above the floor. It
is recommended to use an Hunter Ceiling Fan Extension
Down Rod which lowers your ceiling fan to this level
above the floor.
Hunter ceiling fans use our 3/4” Extension
Down Rods for maximum Stability and Wobble-Free
performance. Most other brands of ceiling fans use
1/2” down rods.
A general formula for calculating
down rod length for your Hunter Ceiling Fan is: ceiling
height in feet minus 9' = down rod length. This formula
is based on the fan-to-floor distance of 8 feet plus
1 foot for the dimension of the fan. So if your ceiling
height is 12 feet, you need a 3 foot down rod for
your ceiling fan in order to properly position the
ceiling fan 8 feet from the floor.
Most Hunter Ceiling Fans have unique Three Position
Mounting Systems. This
canopy may be described as Installer’s Choice®,
WobbleFree™, EasyHang, and HandsFree™
or Three Position Mounting System.
This allows you to mount your Hunter Ceiling
Fan flush-to-ceiling for extra clearance, standard
ceiling fan hanging, or with a ceiling fan extension
down rod on Vaulted Ceilings
with a angle up to 34°!
See illustration below of the Hunter Fan Three
Position Mounting System:

In most cases, the canopy which comes
with your fan will be all that you need if you are
mounting your fan on the Slope of your Vault.
However, if your ceiling angle is especially steep
and exceeds 34° , you should
purchase a Hunter Ceiling Fan Angle Mount
Accessory which will accommodate up to 45°
angles.The angle will increase as your installation
moves closer to the Peak of your vault.
