Intermittent Boiler Heating
I encountered a no heating situation last night with my Burnham boiler and Effikal vent damper. Upon approaching the boiler I noticed that my burners weren't firing but my circulator was running, the pilot was lit, and I had a command for heating. I noticed that the damper wasn't opening, so I flipped the manual operation switch and opened it. After doing this, the burners still did not kick on. I inspected the flame roll out and blocked vent switch and found these components to be functioning correctly.
I figured my next step was to jumper pins 2&3 on the damper vent with the damper in the open position to see if the burners would kick on this way, but it was 2am and this was my garage boiler so I decided to wait for the morning to do more troubleshooting. This morning I woke up to find my boiler functioning perfectly. Great, I fixed it!
Given that I might run into this issue again, what would have been your next steps? Have you run into a situation when burners still don't kick on with the vent manually rotated into the open position? Thanks in advance.
