I want to turn off my water main to repair an outside faucet. Do I have to
shutdown the water heater first? And after I turn the water back on, do I
have to do something to "reboot" the water heater?

In addition to all of the other posting in reply, if you have a hot
water tank heated by NG, you can just turn the control to PILOT for
the time being while doing the repair. After the repair , just turn it
back to the original setting.
