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 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 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 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.
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
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.
Important-when using Model 332H with the Broan Eclipse
Downdraft Models 2830-A or 2836-A: Purchase a
#97011927 Speed Control Kit from your Broan distributor
to replace the speed control in your downdraft.
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 3¼" x 10" discharge.
Transitions are available to connect it to the 10" round inlet
on this exterior-mounted blower.

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.
