A close-mount fan is for lower ceilings.
There are a few standard ways to mount a ceiling fan, depending on the configuration of your room. Some models come with extension rods that hold the fan down from a high ceiling. For a lower ceiling, you need a close-mount kit, which puts the fan housing right up on the ceiling and keeps the blades as high as possible. Measure the width of the existing fixture when you buy your fan, and make sure the fan base is wider than the fixture so it will completely cover the area that the old fixture covered, avoiding the need to touch up the paint.
Instructions
1. Turn off power to the existing fixture at the fuse box. Take down the existing fixture by removing the screws at the base, lowering it to expose the wiring, then disconnecting the wiring. Leave the house wires dangling from the exposed electrical box.
