12.1 Discharge Damper
Discharge dampers are shipped loose. Discharge dampers are designed to be mounted downstream of the
air handler in ductwork. A qualified contractor/installer must make appropriate allowances for duct
connections.
To install the discharge damper on an interior wall, drill holes every 8" (20.5 cm) in the flanges on all four
sides of the discharge damper to accommodate lag bolts (provided by others).
Discharge dampers are not recommended to be mounted directly to the air handler.
