Burnham Boiler 8116327 Damper

The Burnham Boiler 8116327 is a 10-inch automatic vent damper designed to improve the thermal efficiency of atmospheric gas-fired boilers. This motorized flue damper prevents standby heat loss by closing the chimney vent when the burner is off, effectively trapping residual heat within the heat exchanger. Engineered for precise integration with Burnham heating systems, this component features a robust internal motor and a multi-pin wiring harness for seamless communication with the boiler control circuit. The 10-inch damper assembly is critical for reducing fuel consumption and maintaining consistent system pressure. Technicians must ensure proper alignment and clearance within the flue pipe to allow the safety interlock switch to verify the open position before ignition. This HVAC replacement part is built to withstand high flue gas temperatures and frequent cycling, ensuring reliable draft control and peak seasonal efficiency in heavy-duty hydronic applications.

• Mechanical Heat Retention: Dramatically reduces off-cycle heat loss by sealing the flue pipe during standby modes.
• Safety Interlock Integration: Features a built-in end switch to ensure the vent damper is fully open before the gas valve energizes.
• Direct OEM Fit: Designed specifically for Burnham 10-inch flue diameters, reducing field modification time and ensuring a tight seal.
• Improved AFUE Ratings: Enhances the Annual Fuel Utilization Efficiency by preventing the "chimney effect" from drawing conditioned air out of the mechanical room.

Is the 8116327 compatible with other boiler brands?
While sized at 10 inches, this unit is specifically designed for Burnham boiler wiring harnesses. Verify your pin configuration and voltage requirements before attempting to install on non-Burnham equipment.

What causes a vent damper to fail to open?
Most failures result from carbon buildup on the blade pivot points or a faulty internal timing motor. Ensure the flue damper blade has 360-degree clearance and that the wiring harness is seated securely.

Can this damper be installed horizontally?
Yes, the Burnham 8116327 can be installed in vertical or horizontal flue runs, provided the actuator motor stays accessible for service and the orientation complies with local mechanical codes.
