A damper restricts the air flow. In a fireplace, the damper is closed to prevent air from going up the chimney, with a resulting loss of heat in the house, when the fire is not going. When a fire is to be started, the damper is opened to create a draft to vent the smoke. In a wood or coal burning stove, the damper is variable and can be used to regulate the draft. The more widely open the damper is, the greater the draft, and the hotter to fire burns. This sort of damper cannot be closed all the way, because it is necessary to vent slow fires. Sometimes, a stove will have multiple dampers for different purposes. For example, a wood cook stove will have typically a damper on the flue, to regulate the heat of the fire, and a separate damper so the cook can choose to vent the gasses from the fire directly into to chimney, which would be how a fire is started, or around the oven, so the oven can heat nicely once a good draft is established. In other systems where air is moved, dampers can be used to stop the motion of the air. A fire damper is one such system, where the damper is used as a safety device to prevent a fire from spreading. There are links below.
A barometric damper is a device typically installed in a chimney to control the draft or airflow. It uses a weighted flap that opens or closes based on the pressure in the chimney. When the draft is too strong, the flap opens to reduce the airflow, and when the draft is too weak, the flap closes to increase the airflow.
A Barometric Damper when used properly will help regulate the draft. This in return will allow for better combustion, longer burns and less fuel to be used. One problem with a Barometric Damper is the chimney will run a little cooler due to the introduction of room air. If the unit isn't being burned correctly, this can cause creosote to accumulate in the chimney. The Barometric Damper and flue must be checked periodically and cleaned when necessary.
When you press the pedals on a piano, you control the damper on the strings.
The First Known/Recorded Use Of Damper Was In 1707, it was mostly eaten by Stockmen.
Some good wood stoves accessories include stove thermometer, fan, ash scoop, catalytic combustor, back draft damper, heat shield, hearth pad and kettle.

will snow cause my fireplace to have a back draft?
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.

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.
