5. Run 10” round steel duct to installation location.
6. Install 10” damper (Model 421, included) inside the vertical

install in a horizontal ductwork or directly on top of the adapter
or it will not open and close properly.
Remove shipping tape if present. Secure the damper to the
duct with 3 - #8 sheet metal screws (not provided). Ensure
the damper opens and closes freely. Seal all joints with metal
foil duct tape to eliminate air leaks.
NOTE: To optimize airflow and reduce noise, position the
damper at least 17” above the top of the rough-in plate - or
as far as the duct run will allow.
