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

Adaptation to different types of gas
FInjectors replacement
Remove the pan supports. Remove the burner's caps and crowns. With a socket spanner 7 unscrew and remove the injectors (Fig. 7), and replace them with the ones required for the type of gas in use (see table 2). � Reassemble the parts, following the same procedure backwards. � Replace the rating label (placed near the gas supply pipe) with the relevant one for the new type of gas supply. You can find this label in the package of the injectors supplied with the appliance. Should the feeding gas pressure be different or variable compared with the required pressure, an appropriate pressure adjuster must be fitted on the gas supply pipe, in compliance with the rules in force. � � �

Light the burner. Turn the knob on the minimum position. Remove the knob. With a thin screwdriver, adjust the by-pass screw (see Fig. 8). If changing from natural gas to LPG, completely tighten clockwise the screw, until a small regular flame is obtained. If changing from LPG to natural gas unscrew about 1/4 turn the by-pass screw, until a small regular flame is obtained.

turning the knob from the maximum position to the minimum position. This procedure can easily be carried out, anyhow the hob has been positioned or built in the working top.
