Installing fresh air damper, ducting,
and control…
1. Disconnect power from HVAC system.
2. Install the weather hood, ducting, and damper follow-
ing local practices. Be sure all duct and insulation
seams are tightly sealed.
3. Mount the transformer and control.
TIPS:
• In general, larger ducting allows higher airflow,
minimizes additional fan run time and may be needed
for larger homes.
• Installing a damper directly to the return duct may be
convenient to support the damper and reduce ducting.
• Fresh air connection should be downstream of sensors
(such as a humidistat) in return air plenum.
• The EARD6TZ end stops can be used to reduce the
amount of airflow in the duct. To prevent complete
opening, move the red tab to the desired range stop
location.
