The flue damper controls exhaust flow through the vent stack, closing when the burner is off to reduce standby heat loss and improve overall system efficiency. It is installed in the flue outlet of compatible gas water heaters and is typically serviced by licensed plumbers or water heater technicians. The 7-inch diameter matches standard residential and light commercial flue collar sizes used on high-input gas water heaters.\u003c\/p\u003e\n\u003cp\u003eThis flue damper is suited for gas water heater installations where DCG mode operation requires an automatic damper to manage vent airflow. The damper mounts at the flue collar of the water heater and connects into the vertical or B-vent exhaust system. It is appropriate for both new installations and replacement service in residential and light commercial settings where reducing flue standby losses is a system requirement.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-inch diameter flue opening sized for compatible gas water heater flue collars\u003c\/li\u003e\n  \u003cli\u003eDesigned for DCG mode operation, coordinating damper position with burner demand\u003c\/li\u003e\n  \u003cli\u003eReduces standby heat loss by closing the flue when the burner is inactive\u003c\/li\u003e\n  \u003cli\u003eOEM-style replacement for maintaining factory system performance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement flue damper for gas water heaters equipped with a 7-inch flue collar operating in DCG mode.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified water heater technician in accordance with local codes and the appliance manufacturer instructions.
