The EFC 211 is a draft controller that is used with wood-fired appliances such as fireplaces, stoves and pizza ovens.
It consists of a control box and a speed control unit. The control box is typically installed on the outside of the chimney or inside an attic, while the speed control unit is installed in the room where the heating appliance is located. When used with a solid-fuel fired appliance a smoke detector and an audible alarm shall be installed in accordance with NFPA 72, National Fire Alarm Code.
