The pilot assembly provides the standing or intermittent pilot flame that the control valve monitors to prove ignition and allow main burner operation. This part is classified as a replacement part for the 200 and 201 Series water heater platforms. Installation is typically performed by a licensed plumber or gas appliance service technician as part of a pilot system repair or control valve service call.\u003c\/p\u003e\n\u003cp\u003eThis pilot assembly is used on AO SMITH 200 and 201 Series natural gas water heaters across both 40-gallon and 50-gallon configurations. Compatible model designations include units in the GCV, GCVL, GCVH, XCV, XCVL, GVR, GVRL, XVR, and XGV families.
