I have a bathroom with a cathedral ceiling sloped at about 45 degrees. Will the damper operate properly if the discharge is aimed down the slope of the ceiling? If not, are there other options for a damper in this configuration?
The flap on the vent opening of this unit is not spring loaded, but rather it operates on gravity and airflow from the unit itself. Therefore, if you install it with the vent opening oriented upward, it will stay partially open all the time. You might be able to rig a weak spring that would keep it closed when not in use, but allow it to open when the fan is running.
