INSTALLATION INSTRUCTIONS
WARNING: TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK, OR INJURY TO PERSONS, OBSERVE THE
FOLLOWING:
(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.
WARNING: To reduce the risk of fire or shock, do not use with solid state speed controls. This fan is intended for installation facing an unoccupied space only.
IMPORTANT: Read each step completely before beginning your installation.

INSTALLATION
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.

INSTALLATION (continued)
5. After layout is complete, drill a small hole down through ceiling at each corner of cutout. From below, connect these four holes with straight lines to mark cutout on ceiling. Using sabre saw or keyhole saw, cut and remove sheetrock.
6. Refer to Figures 2 and 3. Before cutting joists, lay a
2" x 4" across joists to be cut and adjacent joists, approximately 8" from end of opening. Nail 2 x 4's securely to joists. Cut and remove joist(s) 1 1 ⁄
2
" back from opening.
NOTE: Use caution not to cut sheetrock when you cut joists.
7. Refer to Figure 4. Using lumber the same height as joists, insert two brace back pieces that tie into cutthrough joists and fasten to intact joists at either end of opening. Install headers of same size lumber between the two braces as necessary to complete framing of opening.
8. Refer to Figure 5. Nail 2" x 6" lumber laid flat, around the framed opening to form a platform for the fan. If ceiling joists are 2" x 6" or larger, 1" x 6" lumber can be used.
9. Refer to Figure 6. Install louver at this time. Louver must be installed with 1 ⁄
2
" clearance on all sides. To accomplish this, place small marks 3 ⁄
4
" from edge of cutout in ceiling.
Use these marks to locate shutter and secure with hardware provided with the louver. Install louver opening assist springs. Springs should extend approximately 6" at a 30° angle above louver connecting bar (See illustration). Install nails in frame to hold springs. Allow nail head to protrude 1 ⁄
2
". Install springs between nails and holes in connecting rods.
10. Center fan over opening in attic floor. Align fan so that air through louvers flows toward motor. This will extend the life of the motor.
NOTE: For added quietness, you may attach 1 ⁄
2
" thick rubber stripping to bottom of fan frame.
11. Refer to Figure 7. Capture the fan frame on all four sides by nailing wooden blocks to platform. Rubber padding can be used between block and frame to eliminate any possible vibration.
12. Unbolt the motor carriage from the fan struts. Flip the motor up and rebolt to fan struts. Attach fan belt and slide the motor carriage as necessary to achieve proper belt tension.
CAUTION: Too much belt tension can cause motor to overheat.

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
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.
