Is there much difference between the manual ignition version PF13L160 and the electronic ignition version PF13L160EI?
PF13L160EI has an electronic ignition head. It usually takes 3~5 strikes to ignite a flame on the ignition tube end. Once the flame on the ignition tube end ignites the main burner, you will need to turn off the ignition tube flame to avoid damaging the ignition wire. If you stop the main burner between cooking dishes, you will need to repeat the ignition process for each dish.
PF13L160 has a pilot light and requires manual ignition. You would ignite the main burner at low flame first by turning on the left valve. Then turn on the pilot flame by turning on the right valve. Adjust the pilot flame to appropriate flame size (~0.5 to 1″ in length of flame). The pilot flame stays lit between cooking dishes. If you turn off the main burner between cooking dishes, you only need to turn on the main burner for cooking next dish (no need for any more manual ignition). Because of its simplicity PF13L160 offers better reliability.
