    Steam Boiler Riser location

    I am replacing an old Bryant boiler, which has a single supply riser out the top of the unit with a Utica unit which has a supply out each side. So the recommend piping is to come out each side, rise and connect across the boiler. The riser to the house system would then tee off one side. It would be more convient to place the tee between the two feeds from either side of the boiler so that the connection is centered above the boiler, but I didn't know if that would affect the performance. The several installation manuals I've looked at for steam boilers all show the riser between the boiler suppy and the equalizing loop. What do you think?

    You were smart to notice

    that the manuals showed the takeoff after the risers; the manuals have it right. You don't want the house riser between feeds because you want all the steam travelling in the same direction, not colliding at the tee.

    Also, there should be a slight slope down to the equalizer after the supply risers join. You want the return condensate from the not-yet hot supply pipes coming back down the house riser and going into the equalizer, not backsliding down the supply riser like it would if it were on the wrong side of the slope down to the equalizer.

    Mike, here's a pic

    of what the piping should look like on this type of boiler.
