Hi all, I'm just a residential Dynatherm owner - boiler is from 1957 - with a problem. The issue is NO HEAT this morning. She runs, but has no fire. The emergency push button will fire her up for approx 2 minutes before she shuts down. It's 56 degrees currently in the house - the family is cold! Outside temp is 18 degrees. I wouldn't dream of getting rid of this boiler. She's just got a little cold right now. No pun intended. Anyone have any ideas? Thanks.
