WARNING

TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, OR
INJURY TO PERSONS, OBSERVE THE FOLLOWING:

1. Use this unit only in the manner intended by the manu­facturer. If you have questions, contact the manufacturer
or your distributor.

2. Before servicing or cleaning unit, switch power off at

to prevent power from being switched on accidentally.
When the service disconnecting means cannot be
locked, securely fasten a prominent warning device,
such as a tag, to the service panel.

3. Installation work and electrical wiring must be done by
a qualified person(s) in accordance with all applicable
codes and standards, including fire-rated construction
codes and standards.

4. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) of fuel
burning equipment to prevent backdrafting. 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.

WARNING

5. When cutting or drilling into wall, or ceiling, do not dam­age electrical wiring or other hidden utilities.

6. Ducted fans must always be vented to the outdoors.

7. To reduce risk of fire, use only metal ductwork.

8. This unit must be grounded.

CAUTION

1. For general ventilating use only. Do not use to exhaust haz­ardous or explosive material and vapors.

2. To avoid motor bearing damage and noisy and/or unbalanced
impellers, keep drywall spray, construction dust, etc. off power

PLAN THE
INSTALLATION

ALL INSTALLATIONS

1. Locate the ventilator so
the length of the duct run
and number of elbows
needed are kept to a
minimum.

2. Where possible, ventila­tor should be centered
between wall studs or roof
rafters.

3. Avoid pipes, wires, or
other ductwork that may
be running through the
wall.

LOCATION

ROOF INSTALLATIONS

1. Locate the ventilator on the rear slope of the roof. Place
it in a location to minimize duct run. The location should
be free of obstacles (T.V. leads, electrical lines, etc.). If
the ventilator top is level with the roof peak, it will not
be seen from the street. Keep this approximate location
in mind as you work from within the attic.

2. Mark and drill a guide hole centered between roof

rafters.

WALL INSTALLATIONS

1. Choose a position on the outside wall. Make sure that
no wall studs, pipes or wires run through the opening
area.

2. From inside, mark and drill a guide hole centered
between wall studs.

3. From the outside, use the guide hole as a starting point
to lay out the installation:
A. Use a T-square to measure 913/16" to the left of the

guide hole, then up 1211/16" to locate the top-left
corner of the layout.

B. Starting from the top-left corner, mark the rectan-

gular cutout (18" W x 20½" H) and remove only the
shingles in this area.

C. Mark an 11" diameter hole centered on the guide

hole. Cut this hole through the roof board(s).

D. Mark and cut a 1¼" diameter hole through the roof

board(s) where shown.

4. For flat roof installations, build a curb that will mount the
ventilator at a minimum pitch of 2/12. Discharge end of
the ventilator should be pointed away from prevailing
winds.

3. From the outside, use the guide hole as a starting point
to lay out the installation:
A. Use a T-square to measure 1113/16" to the left of the

guide hole, then up 1411/16" to locate the top-left
corner of the layout.

B. Starting from the top-left corner, mark the rectangular

cutout (22" W x 29½" H) and remove only the siding
in this area.

C. Mark an 11" diameter hole centered on the guide

hole. Cut this hole through the roof board(s).

D. Mark and cut a 1¼" diameter hole through the roof

board(s) where shown.

ROOF INSTALLATIONS

1. Remove the cover and screws.

2. Attach an appropriate U.L. approved cable connector
in the hole at the rear of the wiring box.

3. Remove roofing nails from shingles around the TOP and

SIDES of the cutout area only. Carefully lift the shingles
to allow the back flashing sheet on the ventilator housing
to fit under them.

4. Center the ventilator ring in the 11" diameter hole, making

sure that the 1¼" diameter electrical wiring hole aligns
with the hole in the wiring box.

5. Attach the ventilator to the roof with six (6) screws pro-

vided. It is recommended that the screws be located inside
the ventilator housing. Drill pilot holes if necessary.

6. Using a good grade of roofing cement, seal all of the

shingles around the housing and flashing sheet as well
as the mounting screw heads.

7. Bring electrical wiring through the hole in the wiring box

and secure it according to local codes.

WALL INSTALLATIONS

1. Place a large bead of caulk on the back side of the
housing all along the outer edges.

2. Center the ventilator ring in the 11" diameter hole, making
sure that the 1¼" diameter electrical wiring hole aligns
with the hole in the wiring box.

3. Attach ventilator to the wall with the six (6) screws pro­vided. It is recommended that the screws be located
inside the ventilator housing. Drill pilot holes if neces­sary.

4. Using a good grade of caulk, seal all around the mount­ing screw heads.

5. Bring electrical wiring through the hole in the wiring box

8. Make sure damper opens and closes freely.

9. Top and side flanges of the back plate may be covered
with trim strips. Do not block grille opening at bottom
with trim. It will adversely affect performance of the
ventilator.

INSTALL THE ROUGH-IN PLATE USE AND CARE

1. Run 10" round steel ductwork, from exterior ventilator to
the installation location. For best performance, use the
straightest possible duct run and the fewest number of
elbows. Tape all joints.

2. Run 120 VAC electrical power cable from service panel
and from remote ventilator to installation location.

3. Remove wiring box cover. Remove knockouts from the
wiring box. Feed 6" of power cable through openings
and attach cables to wiring box with appropriate connec­tors.

4. Wire black to black, white to white, and green or bare
wire beneath green ground screw. Replace wiring box
cover.

Disconnect electrical power supply and lock out service
panel before cleaning or servicing this unit.

CLEANING

Remove cover and carefully vacuum ventilator and inside
of housing. Be careful not to bend or otherwise damage
ventilator wheel.
