Looking for someone who has worked on Hytech gas boilers

Jim Robinson

I have a customer with one of these so c~~~ed Hytech boiler that is now out of the picture and it is a funny thing it seems to have a mind of its own. It will run for 1 to 10 days and then will not light for a couple of days or sometimes hours then desides to run again for 1 to 10 days again. ~~~ the safety's are working and the flow switch and the ignitor is sparking but will not light. I have rewired the boiler because I found a short. It did not matter it did it again. Any help?????????????????
