WARNING

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

OBSERVE THE FOLLOWING:

1. 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.

2. Validated performance testing certified for use with BEST, Broan, and Broan Elite

range hoods.

3. This unit is not designed to provide combustion air for fuel-burning appliances.

4. Do not connect the unit directly to a combustion appliance of any type.

5. 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.

6. 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.

7. When performing installation, servicing or cleaning the unit, it is recommended to

wear safety glasses and gloves.

8. During extreme weather events including snow storms, ensure that the intake

area for the outside air duct is not blocked and able to provide a clear pathway for

outside air to enter the system.

9. When cutting or drilling into wall or ceiling, do not damage electrical wiring or other

hidden utilities.

10. When notching or drilling into framing including floor supports, rim joists, and wall

studs, comply with code and manufacturer limitations on allowable modifications

to these structural members.

11. This unit is intended to be installed within the home in a location protected from

moisture.

12. This unit must be in an accessible location which allows for inspection of the unit.

13. Use this unit only in the manner intended by the manufacturer. If you have

questions, contact the manufacturer at the address or telephone number listed in

this document.

14. When federal, provincial or state legislation comprises more restrictive installation

and/or certification requirements, the aforementioned requirements prevail on

those of this document and the installer agrees to conform to these at his own

expense.

AUTOMATIC MAKE-UP AIR DAMPER WITH

TRANSFORMER & PRESSURE SWITCH

READ AND SAVE THESE INSTRUCTIONS

FOR RESIDENTIAL USE ONLY

CAUTION

1. Do not locate outside air inlet near hazardous materials or explosives.

2. Unit shall not be installed to introduce air from crawlspaces, garages, attics,

adjacent dwelling units, or other locations within the building shell. Unit shall be

installed to introduce air directly from outdoors.

3. Do not run the outside air duct directly above or closer than 2 ft to any furnace or

its supply plenum, boiler, or other heat producing appliance.

4. Any ductwork used in conjunction with the Damper must be installed in compliance

with all local and national codes that are applicable.

5. Do not operate the Damper for fresh air introduction until all system filters,

including the central duct system filter, have been installed per the system design.

6. Please read the unit specification label on the product for further information and

requirements.

7. The Damper’s outdoor air intake, ducting, and any filters should be inspected and

maintained on a regular basis.

8. Insulate the duct and damper to prevent build-up of condensation in cold weather

climates. Vapor barriers on both sides of insulation are recommended.

PLAN THE INSTALLATION

Planning the installation first requires selecting the most appropriate installation ap-

proach. The chart below offers suggestions for the most effective installation approach

by considering a few important factors. Further details on the two main types of instal-

lations are provided below.

Yes

• House has central duct work?

Yes

• Return-air side of duct work is

accessible -either the return-air trunk

or return-air plenum?

Damper connected to

return side of central

duct system

Damper ducted directly

to a ceiling, floor, or wall

Outside Air Intake Location

Proper design and location of the outside air intake location is critical in ensuring that

the Damper can safely and reliably provide an opening for fresh air to enter the home.

The following requirements for the location of the outside air intake must be met:

• Outside air intake is located a minimum of 10’ from combustion appliance vents,

chimneys, plumbing stacks, and bathroom or kitchen exhaust vents. If local codes

have more stringent separation requirements, they shall apply.

• Outside air intake is placed high enough above grade to prevent blockage from

snow or other debris such as leaves, and at a minimum of 1’ above grade.

• Make-up air damper should not draw air from crawlspaces, garages, attics, adja-

cent dwelling units, or any enclosed part of the building. The Damper should be

installed to draw air directly from outdoors.

Outside Air Intake Opening Protection

Because the Damper, together with the end cap and outside air duct which are installed

with it, will allow outdoor air into the indoor environment, it is important to meet the

following requirements:

• Model 641FA (6”) and 643FA (8”) fresh air inlet wall caps include protective bird

screens to keep out animals and outside debris. Clean screens often and do not

remove.

• If a protective bird screen other than the screen provided is used, it must cover the

entire opening of the outside air duct. This screen must also have openings of at

least ¼” but no larger than ½”.

• The outdoor air intake opening should meet local code provisions for the protection

of openings in exterior walls, including steps to prevent moisture intrusion around

the opening.

Note that the screen over the outside air opening is not a filter. It is intended to prevent

the intake of leaves, animals, or debris into the outside air duct. A downstream filter is

necessary to remove pollen, dust, and other airborne particles. Potential filter locations

are shown below in the Typical Installations section.

Minimum Return Air Temperature Requirements

HVAC equipment manufacturers may have minimum requirements for the air tempera-

ture in the return air plenum. Introducing outdoor air to the return side of the central

duct system may impact this temperature. The installer should adjust both the size of

the outside air duct and the location of its connection to the return side of the central

duct system in a manner so that minimum air temperature requirements are satisfied

under design conditions.

FREQUENTLY ASKED QUESTIONS (FAQS) 1. What does the Broan Automatic Make-Up Air Damper do? The Broan Automatic Make-Up Air Damper (the “Damper”) provides a pathway for fresh air to enter a home from outdoors when a compatible exhaust device is operating. The Damper opens when a compatible BEST, Broan Elite or Broan range hood is operating, thereby creating a known, controlled point for fresh air to enter the home while air is being exhausted from the building by the range hood.

FOIRE AUX QUESTIONS (FAQ) 1. À quoi sert le Clapet automatique d’air de compensation Broan? Le Clapet automatique d’air de compensation Broan (le « clapet ») permet l’entrée d’air frais dans l’habitation lorsqu’un dispositif d’évacuation compatible est mis en marche. Le clapet s’ouvre lorsqu’une hotte BEST, Broan Elite ou Broan compatible est actionnée, offrant ainsi un point d’entrée contrôlé permettant à de l’air frais de pénétrer dans l’habitation pendant que de l’air est expulsé hors de l’édifice.
