Have you a manual for it? I have a G/W Micron 40FF & had the same 'ignition Lockout'. I downloaded part of the repair manual from the web, it gives LED fault coding. G/W technical suggested the ignitor fault - check for continuity or it was the PCB - Ouch! turned out neither, i tweeked the gas valve to increase the flame and it was away! I don't understand why the gas pressure dropped(?) in the first place??
If you need a PCB which are damned expensive, try boilerpcb.com Very efficient service & half the price of new.
Good luck!
