The stovetop burners on ours have the electric spark ignitors, but the oven does not. You need to light a pilot light which is located on the end of the main oven burner. The oven temp knob has "pilot" as the lowest setting. You need to put the dial on "pilot", push and hold that knob in to start the pilot light gas flow while using a long lighter to get the pilot light flame lit, hold the knob in for several more seconds after lit so the thermocouple gets heated up by the flame, then you can release the knob and the pilot should stay lit. Then turn the oven temp knob to the desired temp and the main oven burner should light off of the pilot. If you turn the oven temp knob back down to pilot, then the main burner shuts off but the pilot light stays on and you can fire the oven back up as needed. If you turn the oven temp knob all the way to off, then the pilot light goes out and you'll have to repeat the lighting process before the oven will fire up again.
The exhaust for the oven burner is from the vents at the rear of the stove top. Don't put anything on the vents to obstruct the exhaust. That exhaust is also very hot. Use the exhaust fan while operating the oven.
