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.
Remove the existing flue pipe. 1  Set the water-heater thermostat to its lowest setting, typically the vacation setting. This will prevent the water heater from turning on and burning you with exhaust gases. 2  Remove the anchoring screw from the base of the flue pipe. 3  Remove the flue pipe.
