Bump for help...
I am also having water heater problems. 1996 Jay 1207 with an atwood heater and white rodgers control. I have been trying to light this thing for a while now and although the pilot sort of lights there is also a flame (bigger than the pilot) coming from the connector through a small hole near the attachment bracket. The hole looks man made as opposed to a crack or something of that nature. I can keep this area lit with the controller on "pilot" for minutes at a time, but the moment I move it towards "on" it extinguishes. As far as I know the lines have been purged, the both inner and outer stovetop connections work fine.

any help would be appreciated.
