Lochinvar & A.O. Smith 100110799 Damper Drive

The Lochinvar & A.O. Smith 100110799 Damper Drive is a critical flue damper actuator designed for 6-inch venting systems on high-efficiency commercial boilers and water heaters. Engineered as the direct 192957-004 replacement part, this 24V motorized drive ensures precise control of the combustion air path, preventing standby heat loss during off-cycles. It features a high-torque internal motor assembly and integrated end switches that provide necessary feedback to the ignition control module, ensuring the system only fires when the damper is in the fully open position. This OEM Lochinvar part is built to withstand high-ambient temperatures near the vent collar and maintains timing sequences essential for preventing flue gas spillage. Technical compatibility includes several series of Copper-Fin II and Power-Fin units where reliable automatic vent damper operation is required for HVAC mechanical code compliance and overall thermal efficiency.

• Ensures precise vent damper positioning to maintain safe combustion sequences.
• Direct 100110799 cross-reference for legacy 192957-004 components, simplifying field installation.
• Reduces standby heat loss by sealing the flue when the burner is idle.
• Robust internal limit switches provide accurate status signals to the main controller.
• Designed for long-term reliability in high-cycle commercial HVACR applications.

Is this damper drive compatible with older Lochinvar Power-Fin models?
Yes, this motorized flue damper replaces part number 192957-004, which was widely used in older Power-Fin and Copper-Fin II configurations. Always verify your specific model's wiring schematic before installation.

Does this unit include the 6-inch damper blade?
This part is the replacement damper motor (drive) assembly specifically. While it interfaces with the 6-inch damper housing, the mechanical blade and vent pipe section are usually sold separately or reused from the existing assembly.

What are the symptoms of a failing 100110799 damper drive?
Common indicators include the boiler getting stuck in the pre-purge cycle, "damper stuck" error codes on the diagnostic display, or the burner failing to ignite because the end switch signal is not being sent to the control board.
