Lochinvar & A.O. Smith 100278106 Vent Damper
The Lochinvar & A.O. Smith 100278106 Vent Damper is a critical OEM replacement component designed specifically for 7-inch flue applications. Engineered for compatibility with RB/RW225-270 boiler and water heater models, this automatic vent damper enhances system efficiency by preventing standby heat loss through the stack. When the burner cycle completes, the motorized actuator closes the baffle, trapping residual heat within the heat exchanger to maintain water temperature and reduce fuel consumption.
This 7" flue damper features a robust mechanical design built to withstand the high-temperature environment of an atmospheric vent system. As an HVAC replacement part, it ensures seamless integration with the existing control board, facilitating proper end-switch proving before ignition. Maintaining a functional flue baffle assembly is essential for meeting modern energy standards and ensuring the equipment operates within its intended performance parameters. Rely on this genuine Lochinvar replacement part to restore domestic hot water and hydronic heating systems to peak operational status.
Key Benefits- Optimized Efficiency: Minimizes thermal energy loss during standby periods by sealing the 7-inch flue.
- OEM Compatibility: Exact fit for Lochinvar and A.O. Smith RB and RW series models 225 through 270.
- Failsafe Operation: Integrates with the appliance's safety circuit to verify the damper is fully open before allowing the main burner to fire.
- Durable Construction: Heavy-gauge materials resist corrosion and deformation under constant thermal cycling.
How do I verify if my 100278106 vent damper is failing?
Technicians should check for a call for heat at the actuator; if the motor does not rotate the shaft or the end-switch fails to close (preventing the 24V signal from reaching the gas valve), the unit typically requires replacement.
Can this damper be used on other 7-inch vent systems?
This specific model is calibrated for the wiring harnesses and control logic of Lochinvar and A.O. Smith units. Always verify the part number against the appliance’s technical data sheet to ensure a proper match.
Does this kit include the wiring harness?
This item typically consists of the vent damper assembly. If the existing harness is brittle or damaged, it should be inspected and replaced separately to ensure a reliable electrical connection.
