This combination valve regulates gas flow and water temperature in one integrated unit, serving as a core safety and control component in the water heater's gas train. Licensed plumbers and water heater service technicians install this part during routine valve replacement or system troubleshooting. The lead wire configuration supports direct connection to the HSI control circuit without requiring additional wire splicing at the valve body.\u003c\/p\u003e\n\u003cp\u003eThis valve is a direct replacement for AO SMITH Series 200 and 201 water heaters equipped with natural gas burner assemblies. It is compatible with both 40-gallon and 50-gallon model variants across the GVR, XVR, XGV, and GVRL product lines. Typical installation scenarios include valve failure replacement, thermostat drift correction, or gas shutoff malfunction service on residential storage-type gas water heaters. The included lead wires simplify reconnection to the existing HSI ignition board harness during swap-out service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNatural gas (NG) configuration for residential water heater applications\u003c\/li\u003e\n  \u003cli\u003eIntegrated gas valve and thermostat in a single assembly\u003c\/li\u003e\n  \u003cli\u003eIncludes pre-attached lead wires for HSI control board connection\u003c\/li\u003e\n  \u003cli\u003eDesigned for Series 200 and 201 water heater platforms\u003c\/li\u003e\n  \u003cli\u003eDirect OEM-style replacement reduces diagnostic and installation time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with AO SMITH Series 200 and 201 water heaters.
