Lochinvar & A.O. Smith 100110668 Flue Baffle

The Lochinvar & A.O. Smith 100110668 Flue Baffle is a critical OEM component designed to optimize heat transfer and maintain atmospheric pressure within the combustion chamber. As a veteran technician knows, a high-performance gas water heater flue baffle is essential for slowing the escape of hot combustion gases, forcing them into a helical path that maximizes contact with the tank walls. This OEM water heater part is a direct replacement for legacy part number 9005815205, ensuring seamless integration into commercial and residential venting systems without the need for field modifications. In high-demand environments, HVAC system diagnostics often reveal that a degraded or dislodged baffle leads to excessive stack temperatures and reduced thermal efficiency. By installing this precision-engineered Lochinvar replacement part, contractors can restore the factory-spec annual fuel utilization efficiency and prevent common issues like harmonic rattling or combustion instability. Designed for durability in high-temperature environments, this baffle is built to withstand the corrosive nature of flue gas condensates while maintaining structural integrity over long-term operation.

• Enhanced Thermal Efficiency: Maximizes heat absorption by slowing exhaust velocity, reducing energy consumption in standard atmospheric and power-vented units.
• OEM Compatibility: Replaces A.O. Smith 100110668 and 9005815205, guaranteeing a precise fit for specific Lochinvar and A.O. Smith models.
• Venting Stability: Helps stabilize the draft and prevent backdrafting issues by maintaining consistent flue pipe pressure.
• Industrial-Grade Construction: Fabricated from heavy-duty materials to resist oxidation and heat-related warping in consistent firing cycles.

What are the signs that a flue baffle needs to be replaced?
Technicians should look for soot buildup, visible corrosion, or "clattering" noises. If the baffle has dropped to the burner plate or warped, it will obstruct the exhaust path and significantly lower the unit's efficiency.

Is this baffle compatible with power-vented models?
Yes, this commercial water heater baffle is designed for use in various atmospheric, power vent, and damper-equipped gas models. Always verify your specific model number against the 100110668 specification to ensure proper length and diameter.

How does this part affect combustion safety?
A correctly seated flue baffle ensures that flue gases are directed into the venting system at the correct rate. This prevents the buildup of carbon monoxide and protects internal components from overheating due to excessive stack heat.
