Connected for 120/240 should be fine as long as there is a few hundred Watts on each leg. You might see minor voltage differences between the legs. Just don't expect to draw more than half the rated kW off one 120 volt leg.

Unbalanced loads are a problem because the rotating field is excited to match the loaded windings. The windings which are not loaded experience higher voltage which can break down the insulation varnish.
