Installed a new water heater last night (Rheem Performance Plus Model #XG50T09HE40U0). All went well with installation (including gas line bubble test), but this morning I could detect a faint smell of gas.
I had re-used the existing gas line last night (except for a new male threaded adapter), but after smelling it today I replaced the line with a fresh one (and reused the new male threaded adapter from last night). All threads were well sealed with thread tape. However, after replacing the line today, I can still detect the smell.
It smells like it's coming from where it is connected in the control unit.

You have used the wrong type of teflon tape - for gas the thicker yellow teflon tape should be used. Another option which many prefer is to use a pipe sealant like RectorSeal.
If after replacing the white teflon the smell persists I would check the other end of the gas line. It's possible that when removing the old gas line an existing fitting was loosened and is now leaking slightly.
