Questions about this item

Will the 7.95 in length and 1.625 in diameter fit my existing Rheem water heater bracket?

The sensor kit measures 7.95 in overall length and 1.625 in outside diameter; compare those dimensions to the bracket opening on your unit before installing.

How can I verify the FV sensor is functioning after I install it?

After installation the burner should ignite normally and the status light on the gas valve will show a steady or blinking pattern described in the heater’s service manual, confirming the sensor is communicating.

Does the kit include the cap plug and wire tie, or do I need to buy them separately?

The kit ships with both the cap plug and the wire tie included, so no extra parts are required for a standard installation.
