Most people would not calculate the wire size, but would calculate the current value and chose a wire size from a table. Your country's electrical code will tell you the wire size needed for the current necessary to supply the stove. This will be around 13.5 amperes. In the US this would require #14 conductors.

Use Ohms Law, compute the (Current + Future Load + allowance), 10% would be enough if it is a direct cable to your stove, but if you want to add more load, then you have to consider them in the calculation, and when you consider the size of wire look at the manufacturers table for the correct size.
Below is the formula:
P=Power in Watts
I=Current in Amps
E=Volts
R=Resistance in Ohms
E=I*R
P=I*E
I=P/E
Always put a separate circuit breaker when your add something this big to your line.
