Cecil ware Fmp65 79lbs. 135000 btu 3burners
 Tristar this has 5 burners can't read any MFG tag
Both units have same problems of lazy top half of burners.
We are running 6 Fryers' I disconnected the largest fryer and hooked a problem fryer up to that port , I still have the same problem.
I shut off all of fryers except one of the problem fryer still have the same problem, burner lazy on top. I am leaning more towards bad propane control valve. What is your thoughts
