If a pilot such as with the Suburban oven in my trailer than the knob will say pilot or pilot on or something like that (I'm not at my trailer and can't check).
To light the pilot light in the oven ...
Turn knob to the pilot position and push in and hold knob.
Immediately light pilot with a match. Hold knob in at least 5 to 7 seconds for this allows gas to flow to pilot and to heat thermocouple.
Release knob, pilot should stay on.
If the oven has not been operated for a long period of time, a longer waiting period for ignition of the pilot may be due to air in the pilot and gas lines.
Good to bleed the lines through the stove top first.
