Looks like a severe case of 'flame roll-out' to me. Try this for an explanation: http://www.fsti.com/rollout.htm

I think you are referring to the evidence of flashback or flame roll out caused by delayed light of the gas stream at the burner. Caused by pilot improperly adjusted or dirty pilopt orifivce or spark assembly misadjusted if electronic ignition which I don't see in your picture.

Was the inner metal "door" in place or missing?

Flame rollout. Typically caused by insufficient combustion air or blocked exhaust venting.

Absent access panel, absent burner cover, rust, debris, flame roll out, and melted drain valve escutcheon. Looks like it's time to replace and make certain access to proper combustion and draft air is upgraded along with the installation.

I looked at this photo 3 times,call me nuts but I think this guy used newspaper and matches to light this heater up.

Ashes,match sticks? I'm still thinking newspapers,mini fire caused the damage.

O.K. now call me nuts!!

Keen eye Mario!!! I didnt even notice that and had to look again. Maybe the cause maybe not,.. I'd still call it out as "indications of roll out, recommend a qualified contractor review further for determination, repair/ replacemnt options or cost for safety"

Becareful about making asumptions to your clients,... may bite you in the ARSE!

Look at the picture file in the first post again.
I just noticed the plastic on the drain valve is melted. I would suggest that this water heater not be used until its been checked by a qualified person. That plastic didn't melt suddenly! There had to be flame outside the burner area for a fair amount on time to cause that. It's lucky it didn't burn the house down.

Matches are from lighting the pilot. Scorching is either from backdrafting (rerverse flow direction of combustion gases) or from pre-ignition (delayed ignition) although I don't see how you could have pre-ignition in a water heater burn chamber with an open-flame pilot.
Backdrafting can be caused by poor drafting as result of poor vent termination location or by negitive air pressure inside the home cause by fans or doors and windows left open on a windy day.

I think the "official" term for this problem is TOAST!
