Looking at the picture of your hot water tank, it appears that somebody (maybe an RV technician at the dealer) has had hte burner tube out of the tank before and didn't do a very good job of re-installing it. Why do I think this? The self tapping screw that holds the burner tube into the main tube is too long, it should not be resting on the electrode bracket. Also the bracket holding the burner by the gas valve is not straight and the gas shutter appears to have been adjusted more open than what is typically expected. Does this have anything to do with your issue? Maybe ... the igniter has been pushed out of position by the too long screw in the burner tube ... it is also possible that whoever disassembled and reassembled this heater altered the gap on the igniter (should be 1/8" gap between the igniter and the ground rod). The igniter also must be centered in the flame. I would also check that the black wire coming off of the igniter is firmly plugged into the circuit board, if this wire is loose the igniter will not spark. You should hear the igniter sparking when the heater is turned on as it tries to ignite the flame. This is a good troubleshooting book if you want to learn more: Atwood/Dometic Troubleshooting Manual
VERY Observant!!!
And right on point-----
gas valve must direct gas flow thru orifice down center of burner tube so air/fuel ratio is achieved
air shuttle is typically on open 1/4 of the way
sparke electrode should not be pressing against burner tube
spark electrode will not spark if gap to narrow or wide(1/8" - 3/16")
