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, fresh outdoor air enters the home through the Damper and is 
then routed and distributed through the home’s ducts. More information on this 
installation approach can be found in the Typical Installations section of this Guide 
(section 8). 
 
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 or other exhaust fans. An installation illustration for 
this situation is included in the Typical Installations section of this Guide (section 8).  
 
9.  What happens after a power outage? 
The Damper system and the associated exhaust devices will not lose their settings 
following a power outage. The system will resume its normal operation following a power 
outage, based on the settings it used prior to the outage.
