The ground (green) wire or wires from the fan assembly should be attached to
the ground (usually bare, sometimes green) lead from the house wiring. Some
older houses may not have a separate ground lead ( this is what I have ) and
use the metal conduit and electrical boxes as ground. In this case you would
attach the ground wire from the fan to the electrical box (and/or mounting
plate) with the appropriate screw or clip.

i also read something that if i have the fan flush mounted that the fan is
already grounded to the ceiling box. the same page also said that if i use
the extention to lower the fan that it is insolated and then it requires a
ground.



i think i am going to try it.
