I'm having difficulty lighting the gas oven of my Sofia Professional Range

Lighting the Bake or Broil Oven Burners

To light the oven burner, press the thermostat knob all the way in for about one second (you should hear the spark module begin to make a snapping sound). Immediately rotate the knob counter-clockwise to the desired temperature setting (at least past the lowest temperature marking of 275 on the knob).

You will feel a small stop as you begin rotation, back the knob out slightly to rotate past this stop. Once the spark module starts it will continue sparking automatically for about 9 seconds even after you release the knob - this is normal and ensures that the sparker is still active when gas begins to flow and does not mean that the burner is not lit. You may hear a whoosh sound as the flame ignites around the burner. You should be able to see some flame through the holes in the floor of the oven cavity and you adjust the temperature further.

In case the burner is not lit return the knob to the 'OFF' position and repeat the above gas burner ignition procedure.

Ignition of the Broiler is the same procedure except the knob is to be turned clockwise to the Broil position.
