yes
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.
In general, open. Doors may be closed when fire has burned down. Even tempered glass may shatter during very hot burns.
because it can harm you or your clothes so you should never play around with half open burners they let out blue flame which is very dangerous because it is the dirtiest falme
u should prefer National Institute Of Open Schooling (NIOS) not this....... coz NIOS is a National open board promoted by CBSE..... & Bse gwalior is a state open board.......

When the fire is burning, until the ashes are cold. The damper should be open at these times.
The purpose of the fireplace damper is to keep the outside elements, outside. The damper is opened only when there is a fire in the fireplace.
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 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.
If the damper should close while a fire is burning, all of the smoke will be coming out in the house- NOT a good thing. Most dampers have a hold-open device held in place by gravity.
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.
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 there is a fire in the fireplace, the flue should be all the way open. Otherwise, some smoke and unhealthful gases will come out into the room. The damper should be all the way closed to keep out wind or cold air when there is no fire in the fireplace.
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.
Shut and Open
Damper is a food that was created in Australia. Damper is made of flour, salt and water kneaded into a thick bread-like mixture. It was cooked over an open fire then eaten. It was commonly made by stockmen and swagmen and others who spent a lot of time travelling in the outback and bush, as it was a simple but filling food that required little preparation time. It is especially tasty with butter and honey.
By flue, I believe you mean the damper in the chimney, which has the effect of closing off the flue. Close the damper any time you are not using the fireplace. Remember -heat rises -so heated air will also rise up and out the flue in the winter. In the summer it is also good to keep the flue closed because heat and humidity will activate the smelly properties of the ash and creosote in the firepalce chimney and create a bad odor in the home. In order for a damper to do its job it must seal tightly/ If your existing mechanical damper is broken, missing or in a bad state you can repair it or replace it with a chimney top damper or a chimney balloon. But, open the damper before lighting a a fire, or it will rapidly get quite smokey in the house.
