You did good research. I doubt 1 out of 10,000 RV'ers would even know to inspect the Baffle to be there. IF they even knew they had one. The critical point since you seem to have done almost everything. EXCEPT-The LP pressure. THAT is critical to LP operation on a refer. Low LP pressure will still yield a blue flame. Also, Did you pull the baffle and did you clean out the flue tube the baffle is in? ANY rust or blockage around that spiral baffle will hinder flue temp operation. You need to state how old the RV/Refer is. Is it possible the baffle has rusted/corroded and is not as long as it needs to be? Doug
