The NAVIEN TANKLESS WATER HEATERS 30008825A Fan Damper is an essential part that is to be mounted in NPE series tankless water heaters to control the amount of air that goes through the combustion and exhaust units. In HVAC systems, it works by changing the direction of air flowing through the internal combustion fan to ensure that the draft conditions and stable combustion are maintained in the heat exchanger of the heater. It is done by placing the damper in the fan assembly or ducting as per the instructions of the manufacturer and fixing it.
