Is the electronic ignition option a separate tool? https://outdoorstirfry.com/product/powerflamer-propane-160-long-lead-time/
The right knob on the valve assembly of the EI option controls the electronic ignition. It is built into the valve assembly, not separate. The left knob controls the main burner flame. After the main burner flame is lit, the electronic ignition flame needs to be turned off.
