Although draft control has always been an important part of the boiler room, its function has changed with burner technology. Today's energy efficient and low NOx burners are sensitive to draft conditions (and ambient temperature, stack oxygen, etc.) Too much draft can cause the burner to run lean, become unstable, and flame out. Too little draft can cause the burner to burn back into the burner internals and damage equipment. In addition, most burner manufacturers require draft controls be installed with their burners for optimal performance.
