most important thing u need is a gas pipe :wink: if u r fitting a standard oven&gass hob (up to 3kw) all u need is a socket outllet in yr kitchen,preferably a double(u will have an igniter 2 plug in 4 yr hob)
icant really c the point of a double pole switch on this fan/light(the fan :idea: ) however if the manufact. spec.says so nothing wrong with putting it on yr lighting circuit.
if we assume this cooker is pulling just over 4kw,then your looking at 20a mcb at your c.u.,20a double pole switch,and 2.5 flex to yr cooker....id check this cable feed and its origin though :?:
