BURNHAM NEW YORKER 8116321 4" Vent Damper

The BURNHAM NEW YORKER 8116321 4” Vent Damper is an HVAC systems that is used for regulating the amount of airflow. It controls the discharge of combustion by-products from heating parts such as furnaces and boilers. This electrically controlled damper remains open during the operation of the burner to enable the safe release of exhaust gases and closes when the burner is off to avoid heat loss up the chimney or flue. This enhances the heating system by lowering standby losses and hence the energy used. It also assists in avoiding back-drafting, to secure proper functioning of the HVAC equipment.
