Lowered Max firing rate down On Mod /Con?
I lowered the max firing rate on my Weil Mclain WM97. Down to 5200 from 5430 and it seems like it is running better. It doesn't Modulate up past the target Temp then come down. It reaches the water set-point nice and slow . What are the pros and cons of doing this. It should be running more efficiently at this rate? What do those numbers actually mean. thanks Dan
