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

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

⁄

" 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 cut-

through 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

⁄

" clearance on all sides. To accomplish

this, place small marks

⁄

" 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

⁄

". 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

⁄

" 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.
