    I like it!

    What size is the boiler? I really like the look of the bushings instead of reducers on the drops.

    Looks good

    but are those Hoffman #75 vents adequate? Those 2-1/2" mains would have to be rather short for the #75s to vent them quickly......

    Main vents

    No not even close, but had to talk customer into

    Adding these two

    After they see results we can add more

    Probably three Gordon's # 2 on each end
