Lochinvar & A.O. Smith 100110275 Gas Control

The Lochinvar & A.O. Smith 100110275 Intellivent Gas Control is a high-performance natural gas control valve engineered for residential power vented water heaters and select commercial boilers. As the direct OEM replacement for part number 9005110005, this Intellivent thermostat gas control features an integrated silicon nitride ignitor driver and an advanced FVIR (Flammable Vapor Ignition Resistant) safety system. It utilizes a 1.5-inch cavity design and a modulating control interface to regulate gas flow based on precise thermal demand, significantly improving fuel efficiency and reducing standby heat loss. For technicians in the field, the digital display provides real-time diagnostic error codes (such as Error Code 4 for open ignitor circuits or Error Code 15 for flammable vapor lockout), allowing for rapid troubleshooting and decreased downtime. This genuine A.O. Smith gas valve ensures factory-spec ignition timing and consistent hot water delivery across diverse hydronic applications.

• Direct Cross-Reference: Seamlessly replaces obsolete part 9005110005 with updated Intellivent technology.
• Advanced Diagnostics: Built-in microprocessor monitors system parameters and identifies flame failure or grounding issues via the LED interface.
• Integrated Safety: Features an automatic ECO (Energy Cut-Off) switch and flammable vapor sensor logic to protect against hazardous operating conditions.
• Optimized Performance: Facilitates precise gas pressure regulation and HSI (Hot Surface Ignition) control for reliable burner cycles in power vent models.

How do I reset the 100110275 after a flammable vapor lockout?

To perform a manual reset on the Intellivent control, cycle the power off for 10 seconds. Within 10 seconds of restoring power, press the two temperature adjustment buttons simultaneously until the "Vacation" LED flashes, then repeat the button press until the status light remains solid.

Is the 100110275 compatible with LP (Propane) systems?

This specific Lochinvar gas control is calibrated for Natural Gas (NG). Using this valve in Liquid Propane (LP) applications requires a specific conversion kit or a dedicated LP valve to ensure safe manifold pressure.

What does a flashing LED status light indicate?

The Intellivent LED flash codes provide specific troubleshooting data. A single flash typically signals normal operation, while multiple flashes indicate hardware issues such as a defective pressure switch, grounding polarity errors, or a faulty flame sensor.
