Hi,
As the title says I’m new at this. I have a problem which I’ve sort of worked thru. Up to a point anyway. We have. Weil-Mac boiler. The vent damper a johnson controls unit is stuck in the open position(which is OK for now). But the burner is not venting properly... there are some blue flames coming out from under the front of the burner. How do I adjust to reduce/eliminate these?
Sorry I don’t know all the proper terms to ask this directly.
THANKS SO MUCH FOR YOUR HELP
