Wood Stove Flue. It is critical to control the air moving in and out of your wood stove. Improper ventilation can cause health issues and be a fire hazard.The wood stove flue helps control this. A flue pipe is a vital part of the exhaust system of the wood stove installation. The flue gases which are released as a result of combustion of wood fuel are hotter than the normal temperature and automatically go upward so it is preferred to install the wood stove flue and chimney in the upward direction.
Cold fireplace f lue. The flue will be cold when you first open the damper. This is especially true in fireplace chimneys built on the outside of the house, rather than up the middle of the house. A tall column of cold air in the flue will tend to sink, causing air to move down the chimney and into the house.oll up a piece of newspaper, light one end, and hold it way up in the damper opening. You might need to burn two rolls of paper. In a minute or so, you will feel the draft reverse, as the warm flue gasses start to move up the flue. Once you have primed the flue, you can light the fire.
