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

When the oven burner lights up there should be a low gas rate at first to the oven burner which is the F.S.D. by-pass rate. 3. When the F.S.D. phial has heated up it opens the F.S.D. valve and the main gas stream flows to the burner. 4. After 1 minute check that the flame covers the full width of the burner and is stable. 5. Set the oven control to Mk. 2, close the oven door and check that after about 10 minutes the flame size has reduced. 6. Turn off the control knob and check that the oven flames go out.
