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?
Sounds like there is a damper closed somewhere.
Put on a pair of safety glasses or goggles (you ARE going to get stuff in your face) get a good flashlight, and get a look at the damper. Most are hinged, and will swing UP the chimney. Most have a bracket and support the holds it open or closed. With the light to help you see, move the support so that it is free of the bracket, and try to swing it open (up). If it does not move, you may have foreign material in the chimney (especially if your chimney does not have a cap). If that is the case, you need the services of a chimney sweep.
closed.
closed curves.

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.
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.
Most dampers are designed to close DOWN, and are kept closed by the weight of the damper. Get a pair of safety glasses and a flashlight, check for foreign material or mortar that may be keeping the damper from seating, and that the metal of the damper plate is not warped.
It is important that you KEEP THE FIREPLACE VENT DAMPER OPEN when you are using it. FAILURE TO DO SO CAN LEAD TO CARBON MONOXIDE POISONING AND DEATH.
yes, it is an open skill i would know bcause i play netball for magikz
Damper is not operating according to flame (high/low) OR Diesel accumulated in Combustion chamber /Ehaust damper may be closed
Closed (I think. All vertebrates I know of have a closed system)

In the event of fire, the fusible link melts and the shutter gets closed. This helps in blocking the fire from spreading through the duct ----- If you are asking about a damper on a stove or chimney, that is not called a fire damper, but just a damper. There is a link to a question on that below.
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.
The damper controls the air flow across the fin-tube. Depending on the heat-exchanging capacity of the tube, which is affected by things like system capacity, pipe size and condition, throttling valves, pump condition, etc., a damper more closed should exchange less heat into the space and a damper more open should exchange more heat into the space.
If points on the circumference are excluded from the locus then an open circle, else a closed one.
