Risers

in THE MAIN WALL
My boiler has two 2" supply tappings.
Can I run a 2" off set riser bushed into a 3" header or does the off set riser have to be 3" also.

    You can do it

    the way you suggest. The steam will slow as it reaches the header and that will help to dry it out.

    Be sure

    the top of your riser is at least 24-inches (or whatever the boiler manufacturer specifies) above the highest possible water level in the boiler. This will also help keep the steam dry since water can't usually rise that far.

    If you run out of headroom, a "drop header" is the solution. Here's one that Noel built. See how tall the risers are?
