It looks like the valves are now in bypass mode. Flip all 3, and they should be in operating mode (see pic below for a typical 3-valve bypass).
If the hot water tank was not full when you operated the electric element, you may have unfortunately burned it up. But I believe the gas should still work.
If you didn't fill the tank already, you need to remove it from bypass mode. Make sure you water pressure (either city hookup or have the pump turned on). Then I would go outside and allow air to escape using the pressure relief valve. Once it is full, then turn the gas on, and see if you get hot water.
