old Atwood water heater help

Thanks all for the help. The label is helpful but doesn't address actually lighting the pilot. The books the previous owner gave me said it had an electronic ignition but after looking at it I knew that wasn't the case. Since this is my first trailer I wanted to be sure I had it right before trying for the first time. I'm not trying to spend $$ fixing things that I break. A new battery and 2 tanks of propane is enough $$ for now.
