Secondly, should damper be open or closed? The damper should always be fully open before lighting a fire and when the fireplace is in use. Close it when it's not it use. Operating the fireplace with the damper partially closed will not generate more heat. Instead, blocking the passage through the flue will result in smoke entering the home.
Moreover, is it OK to close HVAC dampers?
Whether closing supply air dampers will cause a problem; if there's not too much static pressure in the system, closing off supply dampers might actually be ok! The only way to know is to measure static pressure and make sure it aligns with HVAC system manufacturer specifications, even when the dampers are closed.
How do I know if my HVAC damper is open?
Put the damper into an open position and check the registers once again to see if the airflow starts. If the damper is closed and you are feeling low airflow, or none at all, it is most likely a bad damper. For the automatic control damper, turn your HVAC system on. Check for airflow in the registers.
