Best Of

I wanted to take a moment to thank all of you for your feedback and insight. I can honestly say that I would not have been able to do the work that I did without it. I was turned on to the heating help site and this forum by a local service tech and I am grateful for that chance encounter as well. I know there are probably companies here (Southeast Michigan) that can work on steam boilers but they are few and far between. I had several of the local companies out and all of them proved almost immediately their lack of experience. Their screwdrivers only turned clockwise. Many of them were also quick to offer up a replacement of the steam system with something more in their comfort zone. Maybe that would have been the way to go but there is something about steam that I find romantic and nostalgic.

I still have some work to do (skimming, skimming, skimming, adding the valve near the return and insulation) and I will likely have many additional questions. I will do some research first and then start those off in another fresh thread. For now though, my sincerest thank you.

" An improvement would be a solution in which the MV breaks, triggering a timer which holds open the Limit or Thermostat circuit. This would prevent the damper from sitting open during the holding period. But this would likely mean adding another relay into the mix. "

This circuit would basically do that without connection to the MV wiring.

There is nothing in the Burnham Manuals that state anything about the equalizer except:

1. Specify minimum size, no maximum size is given
2. Specify that any size reduction must be in the vertical portion of the equalizer

And this in the attached found in the Steam Max manual.
