When locating fans in a home, always pick rooms where people congregate, like the family room or a bedroom.
In rooms with high ceilings, I like to keep the blade height between 8' and 10' off the floor by using an extension pole.
When wiring up a fan in a new home, the standard, code-compliant electrical supply for a light fixture works adequately. It’s always best to install electrical boxes before doing any wiring so that you can cut your cables to exact length.
When setting your mounting block, remember to recess it far enough from the edge of your ceiling framing to allow for the depth of a junction-box and plaster ring. In existing construction, you can install mounting blocking for your ceiling box by accessing the joists from an attic crawlspace or by cutting a 7" square hole through the ceiling cover. If you don’t want to patch the lid afterward, most lighting stores carry medallions from 8" to 26" in diameter that will conceal the opening, even if you’ve gone crazy with the sawzall. After installing a standard single or double-gang switch box to the wall, you’re ready to run cable. The wiring doesn’t change if you use a three-speed motor control switch, except that you’ll find the switch box a little more crowded. When wiring in retrofits, hooking up your ceiling fan gets a little more complicated, not just because it’s harder to run cable through finished walls but because your power supply might be coming from the light fixture down to the switch instead of through the switch to the fixture.
When replacing an existing ceiling light with a fan, I like to avoid the problems of running an extra hot wire by purchasing a fan with a remote control.
If you’re stuck running a third wire to an existing ceiling box, or have to retrofit a new one, here’s a few wiring tips I learned from my electrician: First, determine the power source.
When you’re ready to assemble and install your fan, open the box and read the instructions. With the ball-mount method, your fan will include either a metal mounting bracket called a “crossbar;” or a ceiling plate, which looks like a pancake box.
Next, attach your fan’s extension pole to the fan motor following the manufacturer’s directions.
Tip: Make sure the detachable hatch or the open end of your mounting bracket faces up on a sloped ceiling, to provide your fan with full support. Tip: If your fan motor comes wrapped in plastic, keep this protective wrapping over the motor until you’ve finished handling it.
For fans with a hanger-pin and yoke system, first insert the hanger-pin and rubber bushing into the hanger bracket, then attach the hanger bracket to the ceiling box. Tip: Don’t forget to slip the canopy onto the pole before hanging the fan, or you’ll have to take the whole thing down and start over. For those of you wanting more information, you can read about how ceiling fans and lights kits are rated for energy conservation at the Building Technologies web site of the US Department of Energy, or check out the Ceiling Fans for Consumers section at the EPA’s Energy Star web site. Homebuilder, developer and author Fernando Pages Ruiz builds in the Midwest and Mountain States and consults internationally on how to build high-quality, affordable and energy-efficient homes. B = the lower limit of anthropogenic modification to the bisona€™s caudal groove, which doubles as the right hip of a womana€™s pelvis. H = the 1st and 2nd shifts in contour that cause the area above to be read as a bas-relief of a bison.
The main art panel, which was largely discovered by one of GERSARa€™s founders, Christian Wagneur, in 1981, consists of two walls, divided from the ceiling by deep creases, that meet in a corner.
The only problem was that the bilaterally symmetrical composition had another type of engraving, which was in no way suggested by the cavea€™s topography a€“ a finely incised horse on the right a€?thigha€? - with nothing, as far as we knew from the Museuma€™s photograph, to echo it on the left. Racing from one speculation to another, I also wondered why such a symmetrical composition had been left lop-sided a€“ with an engraved animal on one a€?thigha€? but nothing on the other. I mentioned my concern about the compositiona€™s lack of balance to Laurent, the author of a GERSAR monograph on another important cave 1, and suggested that we should be looking for the remnants of a second animal on the left. I immediately retrieved my friends and showed them the remains of the horsea€™s head and neck.
Another photo, in white diode light, showing the relationship between the cavea€™s identified art panel and the deep, sinuous, nearly vertical incision on the right. In fact, the second horse was almost certainly found by Wagneur shortly after he noticed the complete one. But that does not affect the storya€™s point, which sets the stage for the proposal of another image by showing how the recognition of compositional gaps or inconsistencies can lead to the rediscovery of an obscured element.
Once the deeply incised groove and flaking were seen as the bisona€™s rear, truly completing it, it also became obvious how lifelike the bison would have appeared if it had been draped with a pelt or painted with pigments that were abraded away on this ridge of the cave floor. Even though Ia€™ve been to the site many times since and tried to find some other reading that can account for the deep incision, flaking, pecking and polishing, nothing seems quite as reasonable to me as this new interpretation, meaning that there could truly be a vulva with hips and a nearly life-size sculpture of a bison - composed of natural relief, a partially chipped contour, pecked and polished musculature, and a deeply chiseled and smoothed rear incision - sprawled in a cave in the Massif de Fontainebleau.
In the first of two planned articles about aspects of this paper, Andrew Howley of National Geographic reported on the papera€™s revelation of one of the worlda€™s oldest known optical illusions: a sculpture from Canecaude, which has eyes on either side of a crescent. Please click on the following thumbnail photos, which Ia€™ve used as icons, to see the web pages or PDFs described in the captions. The deep incision that forms the outline of the right hip and rear of the postulated bison. Traces of anthropogenic modification in and around the groove include the removal of large flakes around its summit (FN), creating the artificial platform where the top of the deep incision starts, as well as signs of incising (IN) and chipping (Ch) within the groove itself, giving it a stepped morphology with a double bevel and saw-toothed right edge.

Here we discuss the more technical aspects of ceiling fan selection and placement and installation tips and take a look at the most advanced, energy-saving models available today.
In homes with radiant heat sources, such as fireplaces or passive solar heating, a fan can push warm air into the rest of the structure, helping the system to work more efficiently. Generally, longer blades move more air, but blade pitch and design also affect performance. A 36" fan moves 2,500 to 4,000 cubic feet of air; a 48" fan moves 4,000 to 8,000 cubic feet. Fan blades should hang at least 7' from the floor and not less than 18" from an adjacent wall or sloping ceiling.
When using an existing service in an older home, make sure your ceiling box has a grounded electrical supply of 120 volts AC, 60 hertz, on a 15 ampere circuit.
This size hole will allow you to wedge a block between the joists and squeeze in your screw gun to fasten it. However, you can install a ceiling box without overcutting by using an expandable fan-mounting brace.
If you’re going to operate the fan’s motor from its built-in pull-chain control, wire the fan like you would any light fixture. Next, splice together the ground that supplies the switch box with the ground from the ceiling box. So don’t assume that an existing ceiling outlet doesn’t have power just because you turned off the switch.
There’s nothing amateurish about this simple step, which might save you time in the long run.
But generally, fan manufacturers use two basic blueprints: the hanger-ball method, which accommodates sloped ceilings, and the hanger-pin and yoke method, used primarily for flat ceilings.
This rod, which connects to the fan motor, hangs suspended from the bushing resting in a metal hanger like a swivel joint; allowing the fan to hang at any angle.
Both of these fasten into your ceiling box, providing attachments for your fan canopy and a grounding screw. If your fan has a one-piece canopy, insert the downrod through the canopy and feed the fan wires though the rod.


Depending on your hardware, you’ll either suspend the fan off a built-in hook at the ceiling plate, or insert the nylon ball at the end of your extension rod into the hanger bar.
Then, using your screwdriver to keep the blade-holder screw in place, position the flange of the holder against the fan flywheel and snug up the fasteners.

The center of the proposed bisona€™s back is also marked by a series of light parallel incisions, but they are not as clearly anthropogenic as the two motifs marking the dorsal line (E) or the 4 incisions over the ribcage.
During a visit to the cave with my friend, Laurent Valois, a member of GERSAR - the association dedicated to studying the regiona€™s rock art a€“ we examined all the elements that we knew of from a photograph on display at the Regional Museum of Prehistory in Nemours, France. These natural fissures originally tapered downwards into the corner, creating the impression of a vulva between thighs. But the panel also includes a deep incision on the right that has been dismissed until now as a mere framing device. Even though this animal was faint, eroded, and just 32.5 cm long from muzzle to tail, one could just make out its mouth, nostril, eye, mane, graceful back and belly lines, and four legs. Parts of it had exfoliated, destroying the original surface, while the rest was so stippled and pocked from weathering that it was hard to distinguish the rounded trace of a washed-out incision.
Although the incision and flaked zone above it have been previously dismissed as a framing device, as we look to the right, wea€™ll see that they are actually the caudal groove and sculpted contour of a largely a€?readymadea€? sculpture of a 190 cm long reclining bison, which appears to be life-size in the small chamber. In 1984, Georges Nelh recorded that one could a€?distinguish another, very effaced curvilinear line belonging to the head of a second equinea€? a€?to the left of the fissuresa€? (Nehl 1984 p. The same approach that led me to re-find the horse head applies to a third, much bigger animal that I missed that very same day a€“ even though one of its elements - a long sinuous line to the right of the clearer horse - also bothered me from the start. If the same artist had also produced the vulva, which used the same method and technique, then the image a€“ quite possibly of an animal - that would be suggested by the adjacent contours would be captured with the same succinctness a€“ a concision typical of Upper Paleolithic art. The furrowa€™s stepped cross-section and saw-tooth right edge indicate that the groove was incised on two occasions, giving it a double bevel, and finally scraped along the right edge, knocking off a succession of chips.
First, it was obvious that the sinuous line was the mirror image of the edge of the left wall, so that the two formed the naturalistic contours of a womana€™s two hips. Oddly enough, the much later prehistoric art in a cavity just two meters away is unusual in having representations of 2 quadrupeds on a similarly raised section of the floor.

The dark rivulet formed by water dripping through the ceiling of this more elevated tunnel can be seen here flowing from the right into the hollow at center left, where the water sinks a€?mysteriouslya€? into a porous or fissured section of the floor, from which the water reappears on the opposite side of the partition on the left, through the vulvar incisions.
Jean Clottes for publication and presentation at the International Federation of Rock Art Organizations (IFRAO) Congress on Pleistocene art in the World, which was held in France fromA  September 6-11, 2010.

A fan makes it possible to adjust comfort in the trouble spots only, without cooling down the whole house. In either case, your ceiling outlet must be rated “for ceiling fan use” and attach to your framing firmly enough to support 50 pounds. Metal boxes install easily with a screw gun and cost less than the plastic boxes designed for ceiling fan use. This box won’t allow much room to tuck wires when you mount the fixture, but there’s always a little extra space in the canopy.
Because you can’t get on either side of the joists, you’ll have to toenail the screws into the mounting block as shown in the illustration. To work the motor and light separately from a wall switch, you will need to run an extra wire from wall to ceiling. If you’re using a metal box on the wall, clip a pigtail from this splice to the box, grounding it. Before you get up on a ladder and start working, make sure the power’s off at the circuit breaker. The control mounts on a holster affixed next to the switch on the wall, or it can lay on your night stand. If so, you’ll still use a three-wire cable, but one of the white wires will become a switch leg. Even my electrician, who has installed thousands of fans, takes a quick glance through the manufacturer’s instructions before putting up a style that he’s unfamiliar with. The first step in hanging your fan will be to secure either crossbar or plate to your ceiling outlet and a ground.
Next, connect the fan wires to the ceiling box wires; white-to-white, black-to-black, and green-to-green (ground).
So make sure your wires come into the ceiling box from above, or parallel with the bracket, to keep them from tangling on the hook.
Sometimes a fan wobbles, but rarely will you have to balance a set of blades after installation. Most fans come with a balancing kit, which includes balancing clips and adhesive lead weights. In 2006, the Department of Housing and Urban Development's PATH project chose him to build America's first PATH Concept Home, a home that is affordable to purchase and to maintain while meeting the criteria of LEED for Homes, ENERGY STAR, MASCO Environments for Living, and the NAHB's Green Building standards. There was even a vertical gully eroded down the center, creating the impression of a vaginal slit. In one of its two figurative readings, it is a kind of frame, since its curve forms a right hip, which mirrors the line formed by the visual limit of the wall to the left of the vulva, which naturally becomes the left hip, with the vulva in the middle. Like the rest of the elongated animal, the legs were so naturalistic, despite their spindly stylization, that they had fine details like hocks and were even shown in perspective. The empty a€?thigha€? was so eroded, though, because of its greater proximity to the closest entrance and elements, that a lightly incised motif might have been largely erased. The line, which took the path of another existing crack, is just as deeply incised as the ones forming the vulva, making it an important compositional element in a figurative ensemble. The hammered and flaked zone at the top of the incision was done to remove stone that reached the ceiling, breaking the desired contour of a bisona€™s rump. The bestial odalisque was naturalistic down to a bearded chin, hump in the right place behind the head, perfect sway in the back, concave ventral line, and, of course, the deeply incised groove that now made sense either as the back of the rear leg or as the bisona€™s tail.
The ventral line of the proposed bison is similar, since it is suggested by a concretionary line and change in relief rather than the a€?overkilla€? of an additional incision. The contour of the proposed back that is highlighted in red does not require any highlighting on-site because the rock seen above the contour in a photo is actually 2 to 3 meters farther away, a fact picked up in the cave by our stereoscopic vision. This feature, which is reported here for the first time and reminds one of a€?miraculousa€? statues of our own period that seem to sweat or bleed, may link the vulva thematically to water despite the cavea€™s distance from the nearest stream or river.
Don’t think of a fan as a chandelier and place it over the dining room table – this common error results in cold food and a fan rarely used, because it’s uncomfortable to have a wind blowing down on you while eating or doing your taxes. In new construction, where the framing is exposed and readily accessible, I cut a length of 2" x 6" mounting block to fit snugly between ceiling joists, providing a stable support to attach my outlet.
Here a screw gun with a magnetic tip is indispensable, so you can hold the mounting block with one hand while fastening it with the other. Both armored and non-metallic cables come in three-phase wire versions, with ground, neutral, and two hots.


Then splice together the common (white wires) from the switch box supply to the fixture run. While convenient for a bedroom, the device requires batteries and it can be a pain to find in the dark. For proper identification, mark both ends of this white wire with black electrical tape, indicating hot.
If your fan wobbles, check the hanger ball on your down rod to make sure it’s properly set into the hanger-pin.
The vulva was a a€?readymadea€? with such a suggestive mineral concretion over the incised triangle that there had been no need to illustrate pubic hair. Another notable feature is the fact that water dripping from the ceiling in the tunnel beyond the engraved wall forms a rivulet that runs two meters down into a small hollow, where it disappears oddly instead of forming a pool. I couldna€™t help but wonder whether some Upper Paleolithic women had such elegant horses tattooed on the inside of their legs.
On close inspection, the area one third of the way down the picture on the right shows signs of pecking and polishing to make the haunch curve in the manner of a living bisona€™s. The top of its rump had been enhanced by the removal of a visually disruptive extension to the ceiling (see the detail) that had broken the otherwise perfect line of its back. There are many cases where it can be shown that the addition of an artificial line where a feature was already suggested by a natural contour was avoided by the makers of Paleolithic imagery, apparently because they felt that the artifice was superfluous and wanted their works to grow from and merge with the surrounding rock. Furthermore, when the dorsal line was traced onto a clear plastic sheet laid directly over the rock from the perspective a person in front of the vulva, it was noted by an observer in the upper chamber, beyond the a€?backa€?, that the person marking the backa€™s ridge had placed it unknowingly directly at the tip of an incised line and adjacent to an incised a€?Xa€? that are out-of-sight behind the a€?backa€?, suggesting that these abstract marks just outside the a€?bisona€? mark its contour or are otherwise related to it.
I find it easier to attach the mounting block by using a battery-powered screw gun rather than nails. Tuck the ground wire splice deep into a corner of the box and tuck the commons into another corner, getting these out of your way. Some manufacturers make devices that operate your fan and light separately from a standard single-pole switch, without adding an extra wire. Run power from the ceiling through this white wire to the wall, splice on two leads--one for each switch. Slide the nylon ball onto the downrod and insert the hanger-pin through the hole in the rod.
When using an extension rod that’s over four feet long, you might need to lengthen fan wires by splicing additional leads.
Then make sure all blades are secured firmly into their holders, and the holders secured tightly to the flywheel. Then stop the fan, chose a blade at random, and place a balancing clip at the midpoint of this blade. The engraver only had to reinforce the cavea€™s features to mark the fact that he had seen a being a€?incarnatea€? in the cavea€™s natural forms - and did so by incising the central and righthand cracks to make them more regular. This natural drain is directly behind and connected to the vulva by a flaw in the rock, causing the vulvar slits to a€?sweata€? profusely.
So the cavea€™s inventory description written by Laurent will have to be revised to cite the horsea€™s original discoverer. This turns out to be true, but perhaps not in the way he thought, since Paleolithic art is rarely if ever framed by artificial borders. Finally, note the sudden color change from pale gray on the incisiona€™s left to brown on its right. Below the flaked rump, a concave zone showed signs of pecking and polishing to improve the swale between the bisona€™s back and haunch. Finally, a tight fan of lines is incised into the ceiling directly above the possible bisona€™s abdomen. Finally, note the sudden color change from pale gray on the incisiona€™s left to brown on its right.A  Although possibly natural, the color change may have influenced the positioning of the incision or be the last remnant of pigment applied to the bison.
Manufacturers often label their product’s actual cubic feet per minute capacity (ACFM) on the packaging, making it easy to do air volume calculations. A set of three 3" screws driven through each joist into either end of the block provides adequate support. I like to use metal connectors because you can loosen them easily and move a cable when needed. A little added torque with an adjustable wrench buries glazing point-like spikes into the joists firmly. Splice two pigtails to the hot (black wire) supply, then attach each pigtail to one of the switches. You control the fan functions by flipping the toggle once for the light, twice for the fan, and three times for both. Make sure to align the hanger-pin with the slot on the nylon bushing or your fan will wobble and spin off the ceiling. Connect the power supply to the leads designated “lights” in the switch housing: black to colored, white to white.
Needless-to-say, this trait, which probably accounts for the pubic concretion as well, may have made the panel more suggestive and life-like. More troubling still, the long sinuous groove had the organic flow usually associated with Paleolithic portrayals of humans and animals. Just as Ia€™d reasoned, the rest of the image was largely a€“ if not entirely - composed of natural relief that almost perfectly reflected the mounds and hollows of a sleeping or dead bisona€™s bones and musculature. Once your cable’s locked in a plastic connector you’ve got to destroy the connector to move it.
Finally, attach the black hot wire from the ceiling run to one switch and the red hot wire to the other. Some high-end remotes attach at the switch box, require two wires only, and control all of the fan functions. Don’t forget to tighten the set screw in the hanger-pin, or your fan will fall off the ceiling.
Do this by placing a yardstick vertically against the ceiling at the tip of a blade, then rotate the fan manually, seeing that every blade tracks at the same distance. At the ceiling box you’ll be attaching the black wire to the motor’s black lead and the red wire to the light’s colored lead. These remotes don’t need batteries and won’t disappear under the couch; but these devices require a canopy and many don’t work on sloped ceiling applications. Check all the blades until you discover the blade on which the balancing clip makes the greatest improvement. Most don’t work on flush-mount fans either, the type of fan you’ll need on most eight-foot ceilings.
Then, slide the clip inward and outward along this blade, testing the fan each time you move the clip, until you find the point of greatest improvement. On some multi-bulb light kits, you’ll feed wires through a lamp ring, and then attach the switch housing cap underneath the ring. Turn the power on at the breakers, flip the fan switches back on, test the fan and light, and then pat yourself on the back for a job well done. The author is participating in the description of the assemblage from the Upper Paleolithic site near Cambrai, which has only been reported in a cursory fashion until now, most notably in Archeologia (March 1992).
