Burnham Boiler 8116324 Vent Damper

The Burnham Boiler 8116324 7" Vent Damper is a critical automatic fuel-saving component designed for atmospheric gas-fired boilers. This motorized vent damper functions by closing the flue pipe during the furnace's off-cycle, preventing residual heat from escaping through the chimney. Engineered for seamless integration with Burnham heating systems, this unit features a redundant safety switch to ensure the burner only fires when the damper is in the fully open position. The 7-inch vent pipe diameter is industry-standard for commercial and residential hydronic applications. For technicians, this replacement flue damper simplifies the installation process with its standardized plug-in wiring harness. Utilizing this thermal efficiency upgrade reduces standby heat loss, significantly lowering annual energy consumption. When performing maintenance or a system retrofit, verifying the B11.21-M8 damper assembly compatibility ensures reliable operation and draft control within the combustion vent system.

• Enhanced Thermal Retention: Minimizes standby heat loss by sealing the vent when the burner is idle.
• Plug-and-Play Integration: Features a factory-wired harness for direct connection to existing Burnham control boards.
• Safety Interlock: Verified end-switch ensures the damper is open before ignition to prevent flue gas spillage.
• Robust Actuator: High-torque motor designed for reliable cycling in high-temperature environments.
• Heavy-Duty Construction: Built to withstand commercial-grade flue gas temperatures without warping.

Is the wiring harness included with the 8116324 damper?
Yes, this assembly typically includes the standard multi-pin plug-in harness for modern Burnham electronic ignition systems.

Can this damper be installed in any orientation?
While designed for horizontal or vertical flue runs, it must be installed according to the flow direction arrows and local mechanical codes to ensure proper draft.

What is the primary indicator of a damper failure?
The most common symptom is the boiler failing to spark or fire because the end-switch has not cleared the safety circuit.
