Which end of boiler do circulators go

Posted by Paul from NH (homeowner) on November 20, 2001 at 22:09:10:

On a home gas forced water boiler, should the circulators go on the return side(pushing cooled water into boiler), or on the output of the boiler(pulling heated water out of boiler and pumping it to the baseboards)?
