It includes a Flammable Vapor Sensor (AP13447-3 - 25VS), a Cap Plug, and a Wire Tie. The kit is compatible with Rheem (Ruud, Richmond) FVIR models, and also fits certain AO Smith and Bradford White units.\u003c\/p\u003e\n\u003cp\u003eThe flammable vapor sensor film responds to gasoline vapors by changing its electrical resistance. That signal is read by the water heater's control circuit, helping the system decide whether to continue heating. No external power is required—the sensor relies on the control circuit's power to monitor resistance changes and process the data. This keeps the replacement simple and compact while preserving the original design intent.\u003c\/p\u003e\n\u003cp\u003eWhen the sensor detects vapor, the control module can shut off the gas supply to the water heater to prevent ignition. This behavior aims to reduce safety risks while keeping downtime minimal and hot water available after a quick replacement.\u003c\/p\u003e\n\u003cp\u003eAfter installing the sensor, many users report the water heater returning to normal operation more quickly, with hot water restored as expected.
