INSTALLATION INSTRUCTIONS
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
INSTALLATION
(A) Installation work and electrical wiring must be done by
qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction.
(B) Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent back drafting. Follow
the heating equipment manufacturer’s guideline and
safety standards such as those published by the
National Fire Protection Association (NFPA), and the
American Society for Heating, Refrigeration, and Air
Conditioning Engineers (ASHRAE), and the local
code authorities.
(C) When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities.
(D) Ducted fans must always be vented to the outdoors.
(E) If this unit is to be installed over a tub or shower, it
must be marked as appropriate for the application.
(F) NEVER place a switch where it can be reached from
a tub or shower.
Refer to Figure 1.
1. Decide upon desired location in central hallway.
2. Remove attic insulation from area where the Whole-House
Ventilator will be installed. Make sure the attic floor is free
of electrical wiring or plumbing pipes. There should be
approximately 36" of clearance between the top of ceiling
joists and the roof. This will prevent back pressure which
can reduce efficiency and increase noise level.
3. Using the template provided on the louver carton,
determine the desired location and orientation of the
louver. Drive a small nail up through the ceiling at one
corner of the template.
4. Locate nail from above. Using this point as a reference,
layout louver cutout.

WIRING
• CAUTION: Electrical connections and all wiring should be
in accordance with the National Electrical Code and all local
codes that may apply.
• WARNING: To avoid possible injury or electrical shock,
disconnect power at fuse or circuit breaker box before
attempting to wire this fan.
• Incorrect wiring may cause motor failure and possible fire.
If necessary, engage the services of a qualified electrician
to wire fan.
Connect electrical wiring from wall switch to motor leads
in motor junction box. If two speed switch is not used, make
sure red lead of motor (low speed) is capped with a wire nut.
IMPORTANT: Be sure to ground fan by connecting ground
wire to ground screw of junction box.
OPERATING FAN
FIGURE 7
Before turning fan on, open windows and interior doors to
insure proper air intake through rooms to be ventilated. If you
have a fireplace, be certain the flue damper is closed to
prevent chimney dirt and soot from being brought into the
house by the fan. Always start fan on high speed and allow
louver to open fully before switching to low speed.
