Could use some help from the heater experts on this issue.
Any idea what is causing flame rollout issue with my recently installed used Raypak R-336A natural gas heater? Seems to be burning below the burners and then roll out to front. I removed top layers until the exchanger and cleaned a pile of dead leaves and now less flame out but still there and won’t stay on. I also cleaned the burner tubes woth a coat hanger wire and they weren’t clogged.
Videos taken after vacuumed.
should I remove gas like and pull out the burner tray to take a look for what is possibly still blocking gas mix from going up and out the top?
i also tried to peek through the burners from bottom and saw something like a layer of white ceramic in the middle of the heater above the burners and below the heat exchanger. What does this do?
