Some help/advice please.
First a question, If there is no flame established at start up should this burner go into lock out immediately or should it try a few more times.
Now the reason for the question. I went on holiday for a few days and turned off the boiler. On my return I turned it on and called for heat. I walked out of the utility room and went about unpacking etc. I returned to the room after a few mninutes and could smell oil, The boiler was cold but the motor was running and there was quite a bit of oil on the bottom tray.
So no flame but oil spraying from nozzle.
I stripped the burner down and checked the spark---it was very weak so I cleaned the electrodes and also the photo cell. Put it all back again with correct electrode gap settings and pressed the button. No problem this time and boiler fired at once. Fixed or so I thought.
Today ( 6 weeks layter) at first start boiler kept on trying to fire for some ten minutes and once again oil dripping into case. It eventually fired up and ran all day. Just to check lock out I shut off the oil supply and lock out happened at once. So the photo cell circuitry seems to know that the flame has gone out but it seems not to sense that the flame has not started and cause a lock out as I think it should
Any thoughts ?
Thanks
