Welcome to the gang Aspro, enjoy here and out in the playground.

Now, I don't have that brand fridge so at a guess the left hand dial would be 240v and numbers would be temp setting, green switch-on and red- off. The left dial on right side looks like turn to the gas symbol and right dial with numbers would be temp setting on gas. The orange switch maybe to light the gas as it says electric ignition.

All a guess of course and I have been known to be wrong so willingly stand corrected.

Hope it works out for you.

Edit....Maybe google the fridge and see what Mr Google has got to say for himself.
