Evening. I've got a new job as maintenance engineer and I was asked to look at an industrial gas oven. Huge thing. Anyway after resetting burner lock out 6 times and it still locked out, my shift partner opened up the burner which is fitted on slide rails, removed the combustion tube and cleaned off the soot from spark electrode and flame detector probe. Simple enough job. Put all back together and tried to start oven. Burner lockout again. Long and short of it, I said we shouldn't be doing this as we are not gas trained let alone gas safe. He said it's ok as we are not touching the gas valve. Can someone clarify this as I'm not happy doing this although what he did was easy enough. It will be alright, we always do it is not a good defence in court in my opinion. Can someone link me to gas safe laws for industrial gas works please.
TIA.
