POSITIONING AND SECURING THE FAN HOUSING
Slide the fan into place with the side of the housing set against
header B and the right-hand
ceiling joist.
Secure the housing to
header B and the ceiling joist using four (4) screws. [1 1⁄2”screws]
Slide and secure
header A between the two ceiling beams with the side of the header set
against the fan housing.
Secure the housing to
header A using two (2) screws. [1 1⁄2”screws]
N.B. You must screw in at an angle in order to ensure proper anchoring.

ELECTRICAL WIRING
Your exhaust fan offers 2 wiring possibilities either using a standard wall switch (SPST) or a 2
position selector switch.
WARNING
A) Before installing, switch off the appropriate circuit breaker in the electrical service panel.
B) Installation must comply with local and national electrical codes.
C) Must be installed by a certified electrician.
D) Unit must be properly grounded.
STANDARD WALL SWITCH (SPST)
The standard wall switch enables you to control the fan and the heat lamp at the same time.
1- Unscrew and remove the wiring compartment cover and pry out one of the knock-outs. The
cable clamp (included) must be inserted through the knock-out hole. (Fig. 6.1)
2- Using the cable clamp, run a cable from the wall switch (not included) into the fan wiring
compartment
3- Using connectors, attach green wires coming from the fan and the heat lamp to the bare
wire (ground) coming from the wall switch.
4- Using connectors, attach the fan and the heat lamp wires located inside the fan wiring com-
partment to the matching wires coming from the wall switch; black to black (hot); white to
white (neutral). (Fig. 6.2)
5- Replace the wiring compartment cover and secure it.
DOUBLE SWITCH
A double switch (not included) allows independent control of the fan and the heat
lamp.
For double switch wiring, please refer to the switch installation guide.

CONNECTING THE DUCTWORK
Connect the duct to the adaptor and secure the junction with duct tape or a duct clamp (not
included). Slant the duct away from the fan to avoid condensation running back into the fan
housing. For attic installations, we recommend the use of insulated ducts to reduce condensa-
tion.
IMPORTANT
• Ductwork must comply with local building codes.
• Ductwork from the fan should always vent to the outdoors through either an exterior wall or
roof.
• To maximize airflow, keep duct length and the use of elbows to a minimum.
