Lochinvar & A.O. Smith 100110727 Conduit Assembly

The Lochinvar & A.O. Smith 100110727 Conduit Assembly is a critical OEM replacement component designed for high-end commercial water heaters and boilers. This ECO/Outlet conduit assembly (which replaces legacy part number 9005911205) provides the necessary structural protection and wire routing for sensitive electrical connections between the Energy Cut-Off (ECO) sensor and the control module. As a veteran technician knows, maintaining the integrity of the water heater electrical conduit is essential for preventing environmental interference and ensuring the ECO sensor assembly communicates accurately with the ignition control board to prevent overheating conditions.

This genuine Lochinvar replacement part is engineered for a precise fit in specific A.O. Smith and Lochinvar commercial units, including many Cyclone and Copper-Fin II models. Utilizing the 100110727 factory-authorized assembly ensures that the wiring remains shielded from moisture and thermal stress, common failure points in mechanical rooms. This kit includes the necessary fittings to secure the run from the outlet sensor to the junction box, maintaining UL-listed safety standards and NPT thread compatibility for a seamless, "drop-in" installation during routine service or emergency repairs.

Key Benefits:

• Precise OEM Compatibility: Engineered specifically for Lochinvar and A.O. Smith commercial water heaters to ensure correct lead lengths and fitting sizes.
• Enhanced Thermal Protection: Shielding prevents lead degradation near the hot water outlet, maintaining consistent signal voltage to the control board.
• Vibration Resistance: Secure conduit fittings prevent connection loosening caused by high-capacity circulating pumps.
• Simplified Service: Replaces worn or brittle ECO conduit assemblies, restoring the safety circuit to factory specifications.

Common Questions:

Which models does the 100110727 assembly fit?
This assembly is primarily used in commercial gas water heaters and high-efficiency boilers. Use your specific model and serial number to verify if this replaces the 9005911205 part number on your unit.

Is the ECO sensor included in this SKU?
Typical for this conduit assembly, the package focuses on the protective housing and necessary wiring leads; always check if your specific repair also requires a standalone ECO sensor or thermistor replacement.

Can I use standard EMT instead of this assembly?
Field-fabricated conduit often lacks the exact multi-pin connectors or moisture seals required for these specific electronic controls. Using the factory 100110727 part ensures code compliance and system reliability.
