Have an electronic ignition boiler. When the heat cycle starts, the damper opens to trigger the end switch and the ignition process starts. It begins to spark but the pilot never lights. I have removed the site glass and I can light it manually with a match. I did this to prove gas out of the pilot assembly. It does light prove pilot and fire the boiler. The problem once it cycles off it will not relight. It will spark until it locks out. Anybody have any ideas?
Thanks in advance for your help!
