Lochinvar & A.O. Smith 100110277 Thermostat

As a seasoned technician, you know that maintaining precise temperature control in propane systems is non-negotiable for system longevity. The Lochinvar & A.O. Smith 100110277 Thermostat is a high-grade White Rodgers Intellivent gas control valve engineered specifically for LP water heater applications. This propane gas thermostat features a 1.25-inch shank and is a direct replacement for the 184768-001, commonly found in A.O. Smith GPSH 40/50 Series 201 models. By regulating gas flow supply based on real-time water temperature, it optimizes energy density and prevents the erratic cycling that stresses tank integrity. The Intellivent control logic includes a 100% gas shutoff safety mechanism that triggers if the pilot flame is lost, ensuring the gas water heater remains stable under load. When diagnosing a water heater not heating, verifying the millivolt output and thermal well integrity of this replacement gas valve is your first step to restoring HVACR performance.

• Direct OEM Compatibility: Specifically designed for A.O. Smith and Lochinvar propane water heaters, eliminating the need for field modifications.
• Integrated Safety Diagnostics: The Intellivent thermostat provides reliable gas shutoff and safe lighting features to prevent main burner engagement without a confirmed pilot.
• Precision Temperature Regulation: High-accuracy sensors maintain consistent setpoints, reducing thermal expansion stress on the storage tank.
• Durable Construction: Features a 1.25" shank for robust mechanical mounting and long-term HVACR system reliability.

What are the signs that a 100110277 gas control needs replacement?
If you encounter a pilot that won't stay lit despite a clean orifice, or if the water temperature is significantly deviating from the dial setting, the internal sensors or the electromagnetic valve are likely failing.

Can this thermostat be used in natural gas systems?
No. This is a dedicated propane gas thermostat. Using an LP valve on a natural gas line will lead to improper combustion and hazardous operating conditions due to the difference in pressure settings and orifice sizing.

Is the 100110277 compatible with all A.O. Smith models?
It is primarily utilized on the GPSH 40 and 50 Series 201. Always verify the cross-reference part number (184768-001) on the existing housing before installation to ensure a proper fit with the 1.25" shank.
