We just got a hampton bay ceiling fan(the one with the hand carved wood leaflook blades) . We have the fan up and running and the light kit hooked up and it works but the golbe that comes with the light kit will not go on right. When we put the globe on it touches the blades causing the light to turn too which I know isn't right. THe problem is there is not enough thread to make the dlobe come down any farther on the finial. Could this simply be fixed by buying a longer finial(thread tube)? Or could something be wrong in the initial installation?
