Is there a "Pilot" marking on the knob? Try moving the knob 1/2 way between on and off and depress the knob. If you are in the correct location, the knob should depress in about 3/8 of an inch. Once you find the location where you can depress the knob, there should be a red sparker button that you can snap to light the pilot. Depress the pilot knob and snap the button a few times. There may be a small viewing port at the pilot. It may be covered by a small metal shield held on by a thumb screw. You can remove the shield to view the flame. OK so now you can depress the pilot knob, snap the sparker, look for the flame while still holding down the pilot knob and count to 30. Slowly release the pilot knob and check to see if the pilot is still on. Once it stays lit, rotate the knob to the "ON" position.
