WARNING CAUTION

EXTERIOR MOUNTEDBLOWER

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 manufac-
turer. If you have questions, contact the manufacturer at the

address or telephone number listed in the warranty.

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

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

ing of gases through the flue (chimney) of fuel burning
equipment to prevent backdrafting. Follow the heating equip-
ment 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.

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.

PLAN THE INSTALLATION

1.

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

Please note = when using blower with the Broan Eclipse
Downdraft: The downdraft has a 31A'' x 10" discharge.

Transitions are available to connect it to the 10" round

inlet on this exterior=mounted blower.

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

unit.

3. Please read specification label on product for further informa-

tion and requirements.

4. Electrical circuit, including speed control, (if used), must be
rated 6 AMPS minimum for Model 332H or 3 AMPS minimum

for Model 331H.

2. Where possible, blower should be centered between wall

studs or roof rafters.

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

through the wall.

4. Be sure that there is enough space for any transitions that may

be needed between the blower and the connecting ductwork.

5. For best performance, locate transitions nearest to ventilator
(i.e. downdraft).

NOTE: Horizontal discharge requires relocation of the duct open-
ing cover plate. See hood manual for instructions.

PREPARE THE INSTALLATION

LOCATION

.

Locate the blower 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.). Bear in mind, if the blower 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.

PREPARE THE INSTALLATION 2
LOCATION

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

opening area.

From inside the attic space:

2. Drill a PILOT HOLE up through the roof, 81/2"
from the inside edge of a ROOF RAFTER.

From outside - on the roof:

3. Measure and mark the 203A" x 201/2" rectangle.
Cut and remove only the shingles inside this

rectangle.

4. Measure and mark the 11" DIAMETER HOLE
and the 11A" DIAMETER HOLE. Cut these holes

all the way through the roof.

From inside the wall:

2. Drill a PILOT HOLE through the wall, 81/2" from
the inside edge of a WALL STUD.

From outside - on the wall:

3. Measure and mark the 25" x 291/2" rectangle. Cut
and remove only the siding inside this rectangle.

4. Measure and mark the 11" DIAMETER HOLE
and the 11A'' DIAMETER HOLE. Cut these holes

all the way through the wall.

PREPARE THE BLOWER

1. Unpack the blower assembly.

2. Remove the cover and screws.

. For flat roof installations, build a curb that will

mount the blower at a minimum pitch of 2/12. See
Figure 2. Discharge end of the blower should be
pointed away from prevailing winds.

3. Remove and discard cardboard from blowerwheel.

4. Remove the wiring box cover and screws.

5. Attach an appropriate CSA approved cable con-

nector in the hole at the rear of the wiring box.

iNSTALL THE BLOWER

INSTALL THE BLOWER 3

1. Remove roofing nails from the upper 2/3 of the
shingles around the cutout area and carefully lift the

shingles to allow the back flashing sheet on the

blower housing to fit under them.

2. Center the blower ring in the 11" diameter hole,
making sure that the 1-1/4" diameter electrical

wiring hole aligns with the hole in the wiring box.

3. Attach the blower to the roof with the six screws
provided. All six holes in the back panel must be

filled, or any moisture that may get inside the

housing could leak into the house.

4. 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.

5. Bring electrical wiring through the hole in the wiring
box and secure it according to local codes.

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

2. Center the blower ring in the 11" diameter hole,
making sure that the 1-1/4" diameter electrical

wiring hole aligns with the hole in the wiring box.

. Attach blower to the wall with the six screws

provided. All six holes in the back panel must be
filled, or any moisture that may get inside the

housing could leak into the house.

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

5. Bring electrical wiring th rough the hole in the wiring
box and secure it according to local codes.
