It could sometimes be a thermocouple that is not properly mounted against the flame or is just defective, these thermocouples are mounted for safety because it would not be good if gas flows out of gas for a long time without flame in professional gas equipment, the gas flow is often Many times higher, by the way a nice device and good brand. I think the damage is very common here. By hand, you might also be able to take it yourself if there is technical knowledge and with the proper attention on gas sealing. look a few examples of your problem from of the link about this.

my smeg oven has always never worked properly, the temperature is faulty etc i now want to remove this oven and have bought a new electrical oven but cannot seem to get the smeg oven out. How do i remove this smeg oven?
This problem is caused by one of two components, depending on the model, there is a thermal cut in thermostat that keeps the fan running until the unit has cooled down and on some models there is a four wire timing device that keeps the fan running for a specific time after the temperature drops, the fault can only be casued by one of these components.

You can get a full manual and installation instructions: http://kitchen.manualsonline.com/manuals/mfg/smeg/a12.html But even though it is a gas range, for the ignition to work correctly, it has to be wired properly. You also have to turn the control on the burner all the way up, to the light position.
two possible causes
first, element is breaking down when hot. one way to check is to put a multi-meter across element and see if it stays powered up.
second, stat is faulty. check if element power cycles with stat
HI ,I have just managed to remove hinges from a smeg a1.1 range. to get hinge out you have tohook up a small holding catch on the bottom bar and thenforce open the hinge, the topbar thencatches on the small catch which then holds the complete hinge open .The whole assembly can then be pulled out. The holding catch is only about 1" long but is easily flicked up with a screw driver Paul 07776 438 408
Mostly when you can light up the pits without the clicker, then that means that there is no power on the stove at all. Check the power cord running to it (which generate the sparks) and see if there is any damage to it.
