Sloped Ceiling Installations
When to Use an Extension Downrod
For optimum performance and appearance, use
an extension downrod with your Casablanca
fan when installing on high (cathedral) ceilings
or sloped ceilings. Casablanca offers accessory
downrods in increments of 6" up to 5’. See your
Authorized Casablanca Dealer for details.
Calculation of Ceiling Angle
Use the tear-off Ceiling Angle Template card inserted
in this manual. It provides you with a simple “go” or
“no go” for installing your fan on a sloped ceiling.
NOTE: The fan may wobble or vibrate if the
downrod length is not long enough and the
inside blade is too close to the downslope or
side wall. Extending the downrod length will
usually solve this problem.
