Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Thank´s for your help, I already recived these manual from you

ELECTRIC SPARK IGNITION
To light the burner you have to rotate the knob corresponding to the specific burner to the maximum flame position (large flame symbol) and press the ignition button marked by the symbol (fig. 3.3). The sparks produced by the electrodes situated next to the burner will light the selected burner. If conditions of the local gas supply makes it difficult to light the gas burner with the knob set to the high flame position, rotate the knob to the lower flame position and repeat the ignition. If the burner flame should go out accidentally wait for at last 1 minute before re-light the burner.
CHOICE OF THE BURNER
On the control panel, near every knob, there is a diagram that indicates which burner is controlled by that knob. The suitable burner must be chosen according to the diameter and the capacity used. As an indication, the burners and the pots must be used in the following way: BURNERS Auxiliary Semi-rapid Rapid Double-ring POT DIAMETER 12 - 16 cm 16 - 22 cm 20 - 24 cm up to 30 cm
do not use pans with concave or convex bases

Fig. 3.2
It is important that the diameter of the pot be suitable to the potentiality of the burner so as not to compromise the high output of the burners and therefore energy waste. A small pot on a large burner does not give you a boiling point in a shorten amount of time since the capacity of heat absorption of a liquid mass depends on the volume and the surface of the pot. N.B. When the cooker top is not being used, set the gas knobs to their closed positions and also close the cock valve on the gas bottle or the main gas supply line. 7
