I just got a 160 propane w electronic ignition. How does the electronic ignition work? No documentation. All can light and adjust it manually. It also looks like it is mounted too far back from the burner.
Attached is the user installation guide. Basically when you turn the right knob, you should hear gas coming out of the ignition tube. When you turn the knob further, a spark should strike the gas. Usually it takes 3~4 strikes to get the flame shooting out the ignition tube to reach the main burner.
