I'll agree to disagree. I work on those all the time and if the vegetation is not up against it and you can walk around it then that is not your problem. Take the removable cover off the top and look if there's debris on the top of the heat exchanger but it can also be sooted up from age and need to be cleaned out so there should be reason for the updraft to happen. Very carefully you can use a airgun with lower pressure and work it up and down all the rows to clear the spaces between the fins. Don't let the airgun touch nor the pressure be too high. That has worked for me time and again. My last raypak also had a roll out issue and besides changing the complete burner tray I also did the heat exchanger cleaning. All works like brand new now.OK, 2 votes for the stack.... I'll keep y'all posted!
I appreciate the additional input. Unfortunately I have already cleaned the heat exchanger and the main burners work great - it's just the pilot that is rolling out.I'll agree to disagree.

And I have had RayPak atmospheric heaters on commercial properties that were in an area with high walls that you could easily walk around that the stack solved a rollout issue.I'll agree to disagree.

Are we talking real walls here then that's a different issue where I see your point.that were in an area with high walls
Walls/solid fencing so the equipment wasn't seen, even from the balconies of the apartments. That's what I was told when asked why they were so high. I didn't install the heaters, but the service company couldn't figure why the rollout.Are we talking real walls here then that's a different issue where I see your point.
