What is the minimum cross sectional area of the flue for a 14 ft tall fireplace with an opening 20 in x 24 in?
As long as there is combustion, the flue should be left open.
You should change the flue if you have ever had a flue fire. you also can remove the base T and use a mirror to look up the flue. If the inside looks warped it should be replaced.
No. The flue must be open to allow the carbon monoxide to escape from the house.
the flue should be opened
It needs to be open when lighting a fire. Close it when not in use. If you have any doubt which is which, look up the flue with a flashlight.

No. Benadyral is used for flue symptoms
if it is instaled corectly, the handle which controlls the flue goes in the same direction as the plate inside the chimney. so if the handle is horizontal, the flue is closed. if the handle is verticle, the flue is open. you shouldn't have to close the flue all the way, at most it should be at a 60degree angle to allow smoke to leave, while retaining heat. open the flue all the way when you open the door to the stove so that the smoke will go out the chimney and not into your face and house. but close the flue back down some to keep in the heat and not waste firewood warmth on the air outside.
