From what I can make out of the label - gas? Looks like the left side is a table of gas regulation parameters for LPG ("GLP"), natural gas and "ciudad" (appears to be another name for natural gas.)
Mine is a 220v that's equipped for gas, but it's a lever/piston machine, and the boiler is pretty huge, so you could go for a while with no electricity. If you're really tied to that 220v line, I wonder why you'd bother with gas.
