4.1 Ignition

1. Ensure the gas supply is open.
2. Push down the desired burner knob and rotate it counter-clockwise to the "High" flame position.
3. Hold the knob down for a few seconds (approximately 3-5 seconds) to allow the thermocouple to heat up and engage the gas flow.
4. Release the knob. The burner should now be lit. If it does not light, repeat the process.
