Hanging ceilling fan from vaulted ceiling
I have a 21 foot ceiling and I want to replace a ceiling fan. I have several questions:
1) the ceilling fan I purchased was from Home Depot, Hampton Bay, 52" Pointe Vecchio model # AC434-WB and in the specifications is says maximum hanging height is 12 feet. What does this mean? Is it 12 feet from the ceiling or 12 feet from the floor or something else?
2) since the height of the ceiling is 21 feet, how long of a down rod do I need for it to be at the proper height? The fan itself is about 2 feet from top to bottom because it has 4 light fixtures that point down from the base.
3) I went to Home Depot to purchase a longer down rod but they did not have one and said you could not use multiple down rods to get the right length or it would wobble and I needed one down rod the correct length. Is this true?
Thanks
