Agree on wire nutting the 120 vac wires. But also turn off the circuit breaker to remove any chance of short due to wire nut working loose.
You could of course remove the offending breaker provided there is no other items on that circuit to be more certain that no power will exist on the unused 120V water heater wiring.. They do make generic block off plates for breaker panels..
Or, just wire nut, wrap a few rounds of black tape around the wire nuts and wire. The black tape will hold the wire nuts even if the nuts get loose..
Many ways to do this but the main key is making sure you do not have any bare exposed wires.
