cold weather climates. Vapor barriers on both sides of insulation are recommended.MODELS G6MD • G8MD • G10MD Page 2

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:

pliance vents, chimneys, plumbing stacks, and bathroom or kitchen exhaust vents. If local codes have more stringent separation re- quirements, they shall apply.

blockage from snow or other debris such as leaves, and at a mini- mum of 1’ above grade.

rages, attics, adjacent 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 environ- ment, it is important to meet the following requirements:

animals and outside debris. Clean screens often and do not remove.

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”.

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 out- side 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 temperature 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.

PLAN THE INSTALLATION

Planning the installation first requires selecting the most appropriate installation approach. 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 installations are provided below.

Turn off the hood and check to see if the damper closes. A qualified HVAC contractor should also ensure the proper operation and venting of all combustion equipment in the home. Wire the system as shown. FALSE TRIPPING Under certain extreme conditions there could be false tripping of the damper (opening when the range hood blower is off). If false tripping is encountered, place an in-line backdraft damper (not included) between the probe and the roof or wall cap. 24V 20V 24V CONTACTS TRANSFORMER WIRINGMODELS G6MD • G8MD • G10MD Page 8 FREQUENTLY ASKED QUESTIONS (FAQS)

1. What does the Automatic Make-Up Air

pathway for fresh air to enter a home from outdoors when a compatible exhaust device is operating. The Damper opens when a 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. By operating in this manner, the Damper provides two key benefits for the home:

allow fresh air into the home to replace air which is exhausted out of the home.

is on, the Damper helps to avoid negative pressure conditions within the home which may interfere with the proper operation of combustion equipment within the home.

and without interfering with the proper operation of other home systems.

2. Does the “Damper” provide combustion air for combustion

appliances like a water heater or a furnace? No. The Damper helps to replace air which is exhausted by a compatible

indoors by a combustion appliance like a natural gas water heater, and it

this restriction is that the Damper is only open when the range hood that it’s connected to is operating. So there is no assurance that the Damper would be open when other appliances, like a water heater, are operating.

3. How do I know if I need make-up air for my

range hood? In some cases the local building code may tell you that make-up air is necessary. For example, some codes specify that range hoods with

mechanical system to introduce make-up air. In other cases, make-up air for a range hood is desirable regardless of whether code requires it. This is especially true for:

easily find its way into the home through cracks, to replace air which is exhausted out.

(i.e. a water heater or natural draft fireplace), which are more susceptible to improper venting if depressurization occurs in the home. In homes with any one of these factors make-up air is advised. And in homes with more than one of these conditions make-up air for the range hood is strongly advised.

4. What are the benefits of providing make-up air to replace air

which is exhausted out of the home by a range hood? Range hoods are designed to pull out pollutants like cooking odors or moisture at the source, so they don’t linger in the home. Because these

from outdoors. Normally this make-up air enters the home through cracks

much more thoroughly so there are not as many cracks and openings. Plus some exhaust fans like range hoods exhaust a lot more air than can be replaced through normal cracks in the building shell. By providing an intentionally designed opening for fresh air to replace air which is exhausted out by the range hood, several important benefits result:

a home without being replaced by new fresh air, are prevented

replacement air is drawn into the home, improving ventilation

5. Does ASHRAE 62.2-2007 – “Ventilation and Acceptable Indoor

Air Quality in Low-Rise Residential Buildings” – require the use of a make-up air damper? ASHRAE 62.2-2007 does not specifically require make-up air dampers. In a few limited circumstances, this standard does require that net exhaust flows from a house be limited. For example, Section 6.4 of the standard limits the net exhaust flow from a home’s two largest exhaust appliances if the home has atmospherically vented or solid-fuel burning appliances located within the pressure boundary of the house. This standard is available at www.ashrae.org.

6. Can I use the Automatic Make-Up Air Damper with other

equipment in my home?

7. What are the different ways that the Damper can be installed in

my home? The most common way to install the Damper is to connect it to a home’s central duct system. In this application, outside fresh air enters the home through the Damper and is then routed and distributed through the home’s ducts.

8. What if my home doesn’t have ducts?

Homes without ducts can still utilize the Damper to help replace air which is exhausted from the home by the range hood.

9. What happens after a power outage?

The Damper system and the associated exhaust devices will not lose their settings following a power outage. So the system will resume its normal operation following a power outage, based on the settings it used prior to the outage. 99045116A Regular maintenance is necessary to ensure the proper operation of the Damper system. Failure to conduct such routine maintenance can jeopardize the ability of the Damper to introduce fresh air into the home. Regular maintenance should include the following activities:

open to allow fresh air to enter.

before it enters the home.

venting the buildup of snow, leaves, or vegetation at the end cap.
