Bring Power to the Attic
Before tapping into a
receptacle or junction box for power, check the amperage on your attic fan,
and make sure you will not overload the circuit. Shut off power to the
circuit. Check with local codes to see whether you need to use armored cable
instead of NM cable.
Mount the Fan
At a louvered opening in the attic,
secure the fan by driving screws through its mounting brackets and into studs.
If the studs do not allow you to center the fan in the opening, attach
horizontal 2x4s that span between the studs. Attach the fan to the studs. You
may choose to install louvers that close when the fan is not operating.
Make the Electrical Connections
The fan has its own
thermostat switch. Mount the thermostat box to a framing member. Follow the
manufacturer's instructions for connecting wires. Restore power and adjust the
temperature control. Or you can control the fan with a pilot-light switch
located in the hallway.
