Heater 240 wiring question
That upside-down diagram seems to indicate you need a 60A circuit to run this heater, but a typical electric clothes dryer (in the US) only has a 30A circuit.  I say circuit because you can't just change the fuse/breaker without increasing the size of the wires.

You will have to look closer at the specifications for this heater to determine the electrical requirements and then make sure that the wire size and breaker are correct for it.
