Do NOT attempt to connect this fan to this ceiling box!
In the USA, a color code is employed to quickly alert the electrician about the voltages found in circuits. Black, red & blue insulated wires with a white colored neutral wire indicates a standard residential 120 / 240 volt system. Brown, orange and yellow wires with a gray colored neutral on the other hand, indicates a common commercial or industrial 277 / 480 volt system.
Since I don't know where you live, but it could be the USA (or other country that also observes this color scheme for system voltage identification), I urge you to contact a qualified electrician. If you insist of checking it out yourself, please exercise EXTREME caution. Accidental contact with 277 volts will burn and most likely kill in an instant.
If it is determined to in fact be a 277 / 480 volt system, the fan you selected will not be able to be connected to this circuit as it is a 120 volt fixture. Connection will result in damage, fire or worse.
I hope this helps. Please rate my reply - thank you!
Continuing from above - You're probably on a 120 / 240 system, and the electricians in Chicago used a color code used to indicate the 277 / 480 system for whatever reason. You need to use a meter (or wiggy) to check though. A test light won't tell you the voltage, and could blow up if not rated for the higher voltage system. Your connections would be between the gray and either the orange or yellow wires to yield a 120 volt circuit. It is also possible that one of those wires is on constantly while the other turns on and off with a switch in the room. But again, you must check with a meter or wiggy, first between the gray to the other two with the wall switch on then off.Continuing from above - You're probably on a 120 / 240 system, and the electricians in Chicago used a color code used to indicate the 277 / 480 system for whatever reason.

If the wires are determined to be set up as one on constantly, the other controlled by a switch - you could connect the "switched wire" to the fixture light wire (blue), the fan wire (black) to the "always on" wire and the white to the gray wire. You could replace the wall switch with a dimmer if you wanted, too. Make sure the switch or pull chain for the light on the fixture is "on" (and then removed to prevent accidentally turning off) otherwise it will never come on with the wall switch. The fan would be controlled solely by the pull chain for on / offIf the wires are determined to be set up as one on constantly, the other controlled by a switch - you could connect the "switched wire" to the fixture light wire (blue), the fan wire (black) to the "always on" wire and the white to the gray wire.
