Description
Genuine Burnham OEM Replacement — Built to Perform
The Burnham 8116325 GVD-8BN is an 8-inch automatic vent damper engineered specifically for gas-fired boiler applications. As a genuine Burnham OEM replacement part, it delivers the precise fit and dependable performance your system demands — eliminating the guesswork of aftermarket alternatives.
Stop Wasting Heat Up the Flue
Every time your boiler cycles off without a vent damper in place, residual heat escapes up the flue and cold air infiltrates the system — driving up fuel costs and forcing your boiler to work harder. The GVD-8BN automatically closes the flue passage the moment the burner shuts down, sealing in heat and blocking cold air intrusion. The result: measurable reductions in standby energy loss and lower operating costs over the heating season.
Automatic Operation, Zero Guesswork
The GVD-8BN synchronizes directly with your boiler’s burner cycle. When the burner fires, the damper opens to safely exhaust flue gases. When the burner shuts off, the damper closes automatically — no manual intervention required. It’s a simple, proven mechanism that delivers consistent efficiency gains throughout the life of the system.
