ELECTRICAL HAZARDS
Danger:The electrical installation and wiring of this fan
must be done by a qualified electrician in accordance 
with all local codes and standards, including fire-rated 
construction. Failure to do the installation properly can
result in fire or even death. 
NOTE: A few hours of operation without apparent prob-
lems does not necessarily imply that the installation is safe. 
Danger:Do not substitute a solid-state speed control for
the thermostatically controlled on-off switch that comes
with this fan. Use of a solid-state speed control can result
in a fire causing injury or death. 
Danger:Watch out for existing electrical wiring and other
utility wires or pipes when selecting a location for the fan.
Do not install the fan where there is electrical wiring in the
way. Select another location or have a qualified electrician
move the wiring to a different location. 
Danger:Make sure the circuit breaker powering the circuit
on which the fan will operate is turned OFF before wiring
the thermostat. You can be shocked or electrocuted if the
breaker is not off. 
LACERATION HAZARDS 
Danger:This fan has an unguarded fan blade. Do not 
use in locations which are readily accessible to people or
animals. Do not let children play in an attic where this fan
has been installed. Contact with this fan while in operation
can result in injury or even death. 
Danger:Switch the power off at the service panel and
lock the service panel before servicing the motor. This fan
is thermostatically controlledÑit may start at any time if the
power is not switched off at the service panel. Contact
with the fan blades while the fan is operating can result in
serious injury.
Warning:This product has sharp metal edges that can
cut your hands. Wear canvas work gloves while handling
the fan during installation. OTHER HAZARDS
Danger:For general ventilating use only. Do not use to
exhaust hazardous or explosive materials or vapors. Use 
of this fan to exhaust hazardous, explosive or flammable
materials may result in a fire or explosion, causing injury 
or death.
CARBON MONOXIDE HAZARD
Danger:Carbon monoxide is a colorless, odorless gas
that can kill. Carbon monoxide may be drawn into the
house by the operation of this fan if your fuel-burning
equipment is not properly maintained and vented orif 
you lack adequate attic venting.
You should check the flue of your hot water heater and 
furnace to see that the pipes are intact and sealed.
Request an inspection from your fuel supplier (gas comp-
any or heating oil company) or from a municipal building
inspector if you have any questions about the safety of
your fuel-burning exhaust system.
You must also check the number and size of your soffit
vents. A total of at least 4.4 square feet (for Model BR28)
or 3.9 square feet (for Model BR26) of unobstructed soffit
venting must be available for safe operation of this venti-
lator. If you have less than the amount specified above,
STOP and install additional vents before proceeding.
TOOLS NEEDED
Electric drill, tape measure, hammer and nails, utility 
knife and pencil, jig or sabre saw, roofing nails, Phillips
screwdriver, adjustable wrench, wire cutter, work gloves
and safety glasses.
1. POSITIONING THE POWER ATTIC VENTILATOR 
ON THE  ROOF:Set the unit approximately in the 
center of the roof close to the ridgeline (as shown
below). Position the ventilator so that the unit can only
be seen from one side of the house.
¨ 
						

							2. DRILLING THE GUIDE HOLE:Measure the distance
to the ridgeline and to one end of the roof. Transfer
these exterior dimensions to inside the attic. Next,
locate a center position between two rafters (inside 
the attic) as near as possible to the outside measure-
ments. Drill a guide hole through the roof from inside
that is equal distance from the two rafters. Place a
marker through the roof for quick identification while 
on the roof.
3. CUTTING THE  HOLE:Draw a circle 14
1/2 in 
diameter using the guidehole as the center. A template 
is provided on the back of the carton for drawing 
the circle.
4. CUTTING THE HOLE IN THE ROOF:Using a sabre
saw, cut and remove all roof shingles (and deck) inside
the 14
1/2-diameter circle. Next, cut an extra 1 off the
top half of the hole (shingles only) to allow room for
placing and positioning the flange. Do not cut through
any rafters. Cutting a rafter may cause your roof to sag. 5. SECURING THE  BASE:Make sure the base flange
parallels the ridgeline of the roof. The embossed arrow
and word UP should be pointing toward the ridgeline.
Slip the upper half of the flange under the shingles. 
Center unit over the hole. Attach flange securely to roof
using roofing nails around the perimeter of the unit
(underneath shingles at the top). A non-hardening caulk
can be used as a seal between the flange and shingles.
6. INSTALLING THE THERMOSTAT:Inside the attic,
separate the thermostat cover from the mounting plate.
Secure the plate to a rafter. See Step 7 to connect 
the thermostat.
7. WIRING THE THERMOSTAT:Wire the thermostat 
as shown below. Attach your ground wire to the 
thermostat box.
Danger:The electrical installation and wiring of this fan
must be done by a qualified electrician in accordance 
with all local codes and standards, including fire-rated 
construction. Failure to do the installation properly can
result in fire or even death. 
NOTE: A few hours of operation without apparent 
problems does not necessarily imply that the installation 
is safe.

							Danger:Do not substitute a solid-state speed control for
the thermostatically controlled on-off switch that comes
with this fan. Use of a solid-state speed control can result
in a fire causing injury or death. 
Danger:Make sure the circuit breaker powering the circuit
on which the fan will operate is turned OFF before wiring
the thermostat. You can be shocked or electrocuted if the
breaker is not off. 
8. THERMOSTAT OPERATION:The thermostat operates
on a temperature setting. Set the temperature dial to a
100 -110 degrees Fahrenheit setting. When the power
ventilator is operational, the fan should start automati-
cally when the attic temperature rises above the preset
setting and cut off when the attic is cooled down to
approximately 10% below the thermostat setting. 
Danger:Switch the power off at the service panel and
lock the service panel before servicing the motor. This fan
is thermostatically controlledÑit may start at any time if the
power is not switched off at the service panel. Contact
with the fan blades while the fan is operating can result 
in serious injury.FIVE-YEAR LIMITED WARRANTY

ment part and will extend for the balance of the warranty
