Found not the correct gas valve in unit and high limit was bypassed due to limit was faulty. Will order new limit and correct valve. 04-25-18 Removed faulty valve and high limit, installed new oem parts (TRS300228, TRS300188). Tested for leaks and operation found no leaks. Also checked gas pressure, it was 3.2 [factory calls for 4] Set to 4 in wc. 04-27-18 Found correct mv on t pile When knob is released pilot will not stay lit but if turned slightly off of pilot position and released with correct mv it will stay lit. Cycled fryer at 350 temp is slightly high at 350 but they needed fryer so I did not calibrate at this time.
