Installing a Ceiling Fan An easy-to-install ceiling fan can make a genuine difference in your house's climate - both heating and cooling - at a way lower cost and operating cost than nearly any other item. The installation starts with selecting where the fan should be found. In just about all houses, the fan is installed in the middle of the room, replacing a central light fitting. This spot gives a smooth air flow to the majority of the room.
Since a fan draws about the same power as a ceiling fixture, the electric circuit should not be overloaded. But if your fan includes lights, be certain the circuit it's on has enough additional capacity to deal with the load. If not, you should run a new circuit with a new circuit breaker from the house main service panel or subpanel to the fan. If there is not any central light fitting, you will have to make a place to hang the ceiling fan. Then, you will need to bring electric power to it.
You can tap into an existing circuit to do that. Check the Blade Clearance Check the floor-to-ceiling peak of the fan blades. You can do this by measuring the floor-to-ceiling distance and taking away for the part of the fan that will extend below the ceiling down to the lower blade surface. An profound minimum height of 7' is commended. Building codes in your neighborhood may fortify this. If the floor-to-ceiling distance is too small, check into a low-ceiling mount for your fan. With some models, the fan blade height can be increased by as much as 10". Remember, though , you need at least 12" between the ceiling and the tops of the fan blades for correct airflow. Having 18" is better if the space is available. Mounting a Ceiling Fan Step one : switch off the Power Start your installation by turning off the power to the light's circuit breaker or fuse. Only then should you take away the light fitting. Ensure to read all of theelectrical safety tips. Step two : Identify Center If there isn't any central light fitting, snap diagonal chalk lines from opposite corners of the room to find its center. Decide whether the lines cross precisely below a ceiling rafter. If they do, move aside just far enough between the beams to fix the side of the fan's new junction box to the rafter. Step three : Install Junction Box Cut a hole big enough for the junction box to be slipped in. If it is next to the beam, drill holes in its side and screw it to the rafter. Installation between rafters is OK, too. Fasten the box to a 2" x 4" header nailed between the rafters. Occasionally , you can insert a 2" x 4" header thru the junction box's hole, nailing it to each rafter. If not, you might need to open a bigger access hole. Then, patch the hole to shut it again. View the image for a standard fan mounting where there's access above the rafters for header-nailing. Tip : you'll decide to employ a patented fan support unit built to be inserted thru the ordinary junction box hole to protect you from opening a hole in the ceiling. Use only a metal junction box to support a ceiling fan - never hang the fan from a plastic box. Depending on the brand, style, and size of your ceiling fan - and your electric code - you can use a 4" or 3" octagonal junction box. ( Some local codes don't permit the utilization of 3" boxes. ) Caution : the most heavy fan that should be supported by an outlet / junction box is 35 pounds.
If it weighs more, the building structure must support it.
Also, your mounting must be in a position to bear vibration while the fan is running.
Even a balanced fan creates some vibration when it runs. Step four : Mounting to a Beamed Ceiling You may employ a special beam mount when mounting a fan to a beamed ceiling. Use one kind for a horizontal beam, another for a pitched beam. You might need an extender to lower the fan to the right level. Caution : Fan-mounting is especially vital because any failure to make things secure could allow your fan to fall from the ceiling.
Assemble the Fan Fan assembly varies from brand to brand. Be certain to follow the categorical instructions with the unit that you purchase. Without regard for the manufacturer's instructions, if the fan blades are less than a screwdriver's length away from the ceiling, it could be best to install the blades before hanging the fan. Step one : Install the Hanger Pipe The hanger pipe is often placed into its hole on top of the motor. The wires are then drawn up in the middle. A set-screw is tightened safely to make certain the pipe stays in place after it is threaded down.
Some fans have a separate motor hub into which the hanger pipe mounts. In this case, you'll place the actual motor housing over the hub.
If Fan has a Decorative Ceiling Cover
Other fans have a two-piece decorative ceiling cover to hide the hole in the ceiling. It is installed after the fan has been hung on the ceiling.
Tip: Tighten the setscrew well if the fan has a Hook-Style Hanger.
Other models use a hook, with the hanger bracket designed to accept it.
Step 2: Attach the Fan Blades
To attach the fan blades, set the motor unit down where it will be stable. Often, the styrene foam packing for the motor housing makes an excellent stabilizer on your worktable.
Most fan blades have a two-pronged attachment, using screws that come through holes in the blades and into the flanges. These need to be drawn up securely, but not so tightly that the threads are damaged or the laminated blade material is crushed. On many fans you'll find the flanges, or prongs, also need to be mounted to the motor housing. If this is the case, mount them before the flanges are mounted to the blades themselves.
