Question About A.O. Smith Water Heater GPSH 40/50
Hot water propane sometimes doesn't lite....

I sometimes get a "System in lockout". I look into the fire chamber while attempting to start. Everything looks clean and the HSI heats up (red yellow). If I turn the gas valve with an allan wrench, it seems to help. What is the proper setting for these two set screws.
