Riello Burner F5 40 Need Help

Tonight I cleaned out my boiler and changed the nozzle. In the process I also cracked the electrodes. The supply house had new ones. I has him help me adjust them but now when I put it all back together it doesn't want to fire. It keeps tripping the reset. I even bleed the line. Any advice is apprecisted.

Thanks

Ok. I solved my own problem. On the end of the nozzle there is a small shroud that screws on to the end. I took this off to change the nozzle and was in a rush to make a hair appointment. Anyway, I thought there was only one way to put this one but apprently I had it backwards and that was interfering with the spray of the nozzle. I like simple fixes.
