Lochinvar & A.O. Smith 100284489 Kit

Ensure the safe and efficient operation of high-performance water heating systems with the Lochinvar & A.O. Smith 100284489 Kit. This genuine OEM flame sense rod assembly is specifically engineered for precision monitoring of the burner flame in Polaris gas-fired water heaters and commercial boilers. As a critical safety component, this rod utilizes flame rectification to send a microamp signal to the control board, verifying ignition and continuous combustion. If the flame sensor fails to detect a presence, it triggers an immediate shutdown of the gas valve to prevent hazardous fuel accumulation. Designed to withstand the high-temperature environment of the combustion chamber, this replacement flame rod features durable construction to minimize carbon buildup and prevent nuisance lockouts. Whether you are performing routine maintenance or troubleshooting an ignition failure, utilizing authentic Lochinvar parts ensures perfect fitment and maintains the factory-certified safety standards of the equipment.

Key Benefits:

• Precise Flame Detection: Communicates directly with the ignition control board to ensure the burner is firing safely.
• Optimized Performance: Prevents irregular cycling and equipment downtime by providing consistent flame rectification.
• Reliable OEM Fitment: Designed as a direct replacement for A.O. Smith Polaris water heaters and specific Lochinvar models.
• Enhanced Safety: Acts as a primary fail-safe to prevent unburned gas from entering the flue or mechanical room.

Common Questions:

What are the symptoms of a faulty flame sense rod?
Common indicators include the burner igniting for a few seconds and then shutting off (shortholding), or the unit throwing a specific "no flame" or "ignition failure" fault code.

Can I clean the 100284489 flame rod instead of replacing it?
While light oxidation can sometimes be cleaned with a non-conductive abrasive pad, a rod with cracked ceramic insulation or significant pitting must be replaced to ensure reliable conductivity.

Is this part compatible with all Lochinvar boilers?
No, this kit is specifically designed for certain Polaris series units and high-efficiency models. Always verify the part number against your specific burner assembly and serial number.
