Roll-Out Flame

[myairplane]

My roll-out tripped and I was able to see flames coming out from the left of the pipe, after removing everything, cleaning and reinstalling, I watched for flames to come out the same spot and they dont, BUT they now to appear to come out from in front - where there isnt the roll-off switch.

See attached pictures.

Is this normal?

What model heater is it? Raypak what?

Did you remove the jets and clean them as well as the long burner tubes? The gas shoots out the jets and down the burner tube where it ignites. If you are getting a flame there, the jet is partially clogged and gas is just slowly leaking out, and is igniting. If the burner tube was blocked, you would probably get a larger flame there. Take that corresponding jet out and clean it.

Its not impossible to have a jet get clogged again after cleaning.

Thank you. I cleaned all the tubes and poked each jet with a paper clip. Is there something else I should have done.

You need to remove the jet and clean. When you poke the jet without removing, you're just sending the debris back into the header only to be blown back into the jet.

Even if you have thoroughly cleaned the orifices and burners ( inside and out ), which may have been the initial cause of the incomplete combustion you still need a clear path for combustion through the heater from the orifices through the burners and heat exchanger and out through the exhaust port. Incomplete combustion ( indicated by a lazy yellow flame ) produces carbon ( soot ) as a byproduct which can get caught in the heat exchanger and block the path of combustion further with a snowballing effect. You should check the heat exchanger for blockage to ensure the path of combustion is not blocked in any way. Full model number from your heater would be helpful because from the information given, I cannot tell if your heater is natural draft or induced draft or its age. Rollout itself is indicative of a blockage upstream from the burners.
