Lock Out No flame IGN on Lochinvar Knight Boiler Mod KBN105
Been having trouble getting someone to my house, I guess since the cold season has come, so I tried to fix my boiler myself. When I called the repairman they said the problem was probably the ignitor. So I got a new one and installed it. When I started the system back up I got the same response and no fire. It just goes through the pre purge and then after the ignition fails, the post purge. It does it three times and then locks out. It has to be something really basic. I just had the thing serviced and cleaned by a professional. Can anyone help??
