    ChrisJ, you might be right. I don't know what the operating characteristics of the boiler are when derated by manifold pressure. I know that the LGB series is available with a 2-stage valve and I have been told that it remains very efficient on low fire. So, for the EG, I don't know. Did you do any efficiency testing on yours in an underfire operation? I was told by one of the pros that my old Pennco, which was firing at a reduced rate would have a high amount of excess air and a significant loss of efficiency. The huge improvement when the boiler was replaced seemed to substantiate that.

    No testing on mine in that regard as I don't plan in underfiring it. When it gets cooler out Jstar will be coming out to set things out so maybe he'll be interesting in trying that, I don't know.

    What's up with that connection into the chimney?

    The chimney was just lined, thats the bricks just shoved back into place, it all needs to be cemented. The boiler is fully connected to the flue.
