Examined Gas Fryer unit, found left side extension rob knob broken and right valve hard to turn. swapped right knob over to left and lit pilot. was able to get right side to light but valve sticks and is difficult to turn. right valve should be replaced. will order parts for right side and return gas shut off is NOT behind fryer. will need to make sure work is performed before 3:30 so Bob can show tech where gas shut off valve is located. 2-1-19 Removed and replaced right side gas valve, thermocouple, and rod extension knob. tested. unit lit and cycled. good to go
