Burnham Boiler 8116325 Vent Damper

The Burnham Boiler 8116325 Vent Damper is a mission-critical 8-inch automatic vent damper designed specifically for Burnham gas-fired boilers. This GVD-8BN model functions as an electromechanical safety and efficiency device, preventing heated air from escaping through the flue when the burner is off. Built for high-heat environments, the vent damper assembly ensures consistent HVAC efficiency by maintaining the thermal mass within the heat exchanger. For HVAC contractors, this unit is a direct OEM replacement part, engineered for exact fitment and seamless integration with existing 24V control circuits. Proper installation of this power vent damper reduces standby heat loss, significantly improving the overall Annual Fuel Utilization Efficiency (AFUE) of the heating system. When troubleshooting Burnham boiler parts, ensuring the damper signal is correctly interfaced with the gas valve is essential for safe ignition cycles and preventing stack draft cooling.

• Efficiency Optimization: Reduces off-cycle heat loss by sealing the flue when the boiler is not firing.
• OEM Compatibility: Specifically engineered for Burnham series boilers requiring an 8-inch GVD-8BN vent damper.
• Safety Interlock: Features an integrated end switch to confirm the damper is fully open before allowing the burner to ignite.
• Heavy-Duty Construction: Built to withstand commercial and residential flue gas temperatures without warping or binding.

Common Questions

How do I verify if the 8116325 is the correct size for my boiler?
Measure the diameter of your existing flue pipe. This unit is specifically designed for 8-inch flue outlets. Always check the boiler rating plate and parts list for the Burnham 8116325 part number to ensure exact electrical and mechanical compatibility.

What are the symptoms of a failing boiler vent damper?
Common indicators include the burner failing to ignite (due to the end switch not closing), visible soot buildup, or the motor failing to move the blade to the open position during the startup sequence.

Can this damper be installed in any orientation?
It is recommended to install the GVD-8BN in accordance with the manufacturer's specified clearance and positioning to ensure gravity does not interfere with the drive motor or the mechanical linkage.
