Rheem-Ruud SP13846A Gas Valve

The Rheem-Ruud SP13846A Gas Valve is a critical OEM replacement component engineered for residential liquid propane (LP) water heaters. This 120V gas control thermostat features a 1/2" NPT connection and is calibrated for a 10" water column (WC) output, ensuring precise manifold pressure for high-efficiency burner operation. Designed for sealed combustion models, this assembly integrates electronic ignition protocols and sensitive thermostatic feedback to manage tank temperature with professional-grade accuracy. It is a direct physical and functional match for Rheem, Ruud, and Richmond systems, utilizing a 2-3/8" shank length for secure threading into the tank vessel. Technicians can rely on the SP13846A for restoring system integrity during service calls involving ignition failure, sensor drift, or valve body malfunctions. By maintaining the combustion safety and thermal cycles required by the manufacturer, this valve ensures the burner assembly operates within strict OEM parameters without the need for field modifications or generic adapters.

• OEM Precision: Genuine Rheem replacement part ensures exact fitment and avoids the reliability issues common with universal aftermarket valves.
• Electronic Integration: Specifically designed for 120V ignition systems, coordinating flawlessly with direct spark or hot surface igniters.
• Consistent Heat Regulation: Built-in gas control thermostat maintains stable water temperatures and prevents overheating via internal safety limits.
• LP Specific Calibration: Factory-set for liquid propane at 10" WC, eliminating the risk of incorrect manifold pressure during installation.
• Robust Construction: Features a 1/2" inlet/outlet and a 2-3/8" shank length for durable gas line connectivity in residential applications.

• Is the SP13846A compatible with Natural Gas systems? No, this valve is factory-calibrated for Liquid Propane (LP) only. Using this on a Natural Gas unit can cause hazardous combustion conditions.
• Does this valve require an external power source? Yes, this specific model operates on a 120V AC circuit and is intended for water heaters with electronic controls, not standing pilot millivolt systems.
• What are the signs that a gas valve needs replacement? Common symptoms include a pilot that won't stay lit, burner ignition failure, or inaccurate water temperature readings that cannot be resolved through sensor cleaning.
