Answer: All household appliances that carry out combustion for operation need proper venting to send the exhaust gases outside the house. After the combustion, the warm combustion gases rise in the flue and go out. These exhaust gases instead of going up the flue to find their way into the surrounding can come down and reach your living space. This is called backdrafting. This happens if the air pressure in the room is quite lower relative to the air pressure where the flue terminates outside.
