Lochinvar & A.O. Smith 100141552 Damper
The Lochinvar & A.O. Smith 100141552 6 Inch Vent Damper Assembly is a critical component for maintaining high combustion efficiency in atmospheric gas-fired boilers and water heaters. This automatic vent damper is engineered to prevent standby heat loss by sealing the flue during the off-cycle, preserving the residual heat within the heat exchanger and reducing fuel consumption across residential and light commercial applications. Built for rugged field reliability, the 100141552 is a direct OEM replacement part that ensures the safety of the exhaust system by utilizing an integrated proving switch—this end switch verifies the damper blade is in the fully open position before allowing the burner to ignite, preventing flue gas spillage.
Designed for 6-inch venting systems, this motorized assembly is compatible with a wide range of Lochinvar and A.O. Smith equipment, including select series of the Lochinvar Knight and residential water heater models. It serves as the authorized successor to legacy part numbers such as the Lochinvar DRH2936. When troubleshooting HVAC vent dampers, veteran technicians should check for 24V power at the actuator; if the motor fails to drive the shaft to a vertical position or the proving switch fails to close, this assembly provides a drop-in solution to restore system operation without the need for complex rewiring or bypass modifications.
Key Benefits- Enhanced Fuel Efficiency: Minimizes heat loss during standby cycles, providing immediate improvements in boiler energy efficiency.
- Safety Interlock System: Features a high-reliability end switch to ensure proper water heater venting and prevent burner operation if the flue is obstructed.
- Direct OEM Fit: Guaranteed compatibility for 6-inch exhaust runs on Lochinvar and A.O. Smith units, replacing obsolete models like the DRH2936.
- Simplified Installation: Standard 24VAC wiring and bolt-on 6" collar design allow for rapid field replacement by contractors.
What are the signs that my 6-inch vent damper needs replacement?
Common failure points include a seized actuator motor or a faulty proving switch. If your boiler has power but the burner won't cycle, check if the damper blade is stuck. A stuck closed damper will prevent the system from getting the "all clear" to fire.
Is the 100141552 compatible with other brands?
While designed primarily for Lochinvar and A.O. Smith, this 6-inch HVAC damper follows standard industry specifications for 24V atmospheric systems. Always verify the connector pinout and diameter before attempting installation on non-specified brands.
Can I manually override the damper if the motor fails?
Most technicians advise against permanent overrides as it bypasses critical safety protocols and reduces efficiency. This assembly is the professional choice to restore automatic operation and maintain code compliance.
