For a fireplace, you should have a flashlight, and a pair of safety glasses (you WILL get soot in your face the first time). Kneel, lean over, shine the light up the chimney. You should see a rectangular metal plate- that is the damper. Usually has a handle that has notches on one side. Move the handle so that the notches are clear of the frame, and push up on the handle- damper should swing open. Hook the notches on the frame so that the damper STAYS open. Now use the flashlight to check for any foreign material (leaves, dead birds, animal nests) that may have been sitting there- they need to be removed before using the fireplace. A metal chimney cap will keep that stuff out. Now go wash your hands. And probably, your face.
To open a fireplace damper, locate the handle or lever usually located inside the fireplace or on the chimney. Pull or push the handle to open the damper fully, allowing for proper ventilation and airflow in the fireplace.
On mine if you turn the nob clockwise, that openes the damper. If you trun the now counter clockwise that closes the damper. Yours may be different. Let me think. Did you have anything in your stocking this morning?
The HVAC damper in the current system is closed.
The furnace damper should be open in winter to ensure efficient heating.
A top damper or cap damper is a metal spring door placed at the top of the chimney with a long metal chain that allows one to open and close the damper from the fire place.
There should be a lever somewhere on the duct near the furnace. If it is open, the lever will be parallel to the duct. If the damper is closed, it will be perpendicular to the duct.
Shut and Open
When you use the fireplace, the damper should be open all the way. If not, you probably will not get enough updraft and your house will fill up with smoke...not a good thing. When it is not in use, the damper should be closed...otherwise you will lose a lot of heat up the chimney.
When the fire is burning, until the ashes are cold. The damper should be open at these times.
Your chimney damper is open
yes
In most cases, the fireplace damper is open when the chain is up and closed when the chain is down. Pulling the chain up usually opens the damper to allow smoke and gases to escape, while pulling it down closes the damper when the fireplace is not in use.
