Description
The BURNHAM NEW YORKER 8116325 Vent Damper is a mechanical airflow control component designed to regulate flue gas passage in heating equipment by opening and closing the vent pathway. It features an 8-inch diameter damper assembly with model designation GVD-8BN, intended for integration with compatible boiler venting setups. In HVAC systems it is used within gas-fired boilers to reduce heat loss during standby operation by limiting chimney draft when the burner is off. It is typically fitted into the vent pipe section, where it responds to system demand and assists in maintaining stable combustion efficiency.
