Lochinvar & A.O. Smith 100276287 Thermostat
The Lochinvar & A.O. Smith 100276287 Thermostat is a high-precision K Gas Thermostat MFG-H CONV designed for professional-grade temperature regulation in commercial and residential water heating systems. Engineered as a direct OEM replacement part, this manual reset gas thermostat effectively manages heat levels by modulating the gas supply based on real-time fluid temperatures. It operates within a precise 40°F to 120°F temperature range, ensuring accurate thermal control and system safety. This unit is specifically built for gas conversion kits and conventional heating applications where maintaining a consistent setpoint is critical for operational efficiency. Contractors often utilize the 100276287 when upgrading older Honeywell L6 series controls or performing a water heater gas valve replacement. The rugged construction and factory-calibrated sensors mitigate common issues like temperature overshoot and erratic cycling, providing the reliability required in high-demand environments.
Key Benefits
- OEM Compatibility: Precision-engineered for seamless integration with Lochinvar and A.O. Smith gas-fired equipment.
- Manual Reset Feature: Enhances system safety by requiring a physical intervention if high-limit thresholds are exceeded.
- Broad Operating Range: Supports a variety of heating applications with a verified 40°F to 120°F thermal band.
- Accurate Calibration: Reduces energy consumption by preventing over-firing and maintaining tighter temperature differentials.
- Standardized Fitment: Designed as a drop-in replacement for legacy Honeywell L6 controls, streamlining the installation process for technicians.
Common Questions
Is the 100276287 compatible with propane (LP) units?
This thermostat is primarily designed for MFG-H conversion in natural gas configurations. Always verify your specific manifold pressure requirements and orifice sizes before installation, as gas types require different regulation settings.
Can this part replace a digital gas control valve?
The 100276287 is a mechanical K Series gas thermostat. It is intended for systems designed for manual reset and mechanical sensing rather than those requiring integrated electronic ignition or digital communication protocols.
What are the symptoms of a failing gas thermostat?
Common indicators include fluctuating water temperatures, a recurring "no hot water" condition due to a tripped ECO, or a burner that fails to cycle off once the desired setpoint is reached.
