Every forced hot water system requires a circulator. A
separate circulator or zone valve is required for each
zone, if there are two or more zones.
The circulator must
have the capacity to provide the circulation required by
the heating system. The circulator should be connected
to the supply main and must be wired into the boiler’s
electrical system. See the
“System Piping”
section for
piping configurations with the circulator located on the
supply main piping using zone circulators or zone valves.
When the piping is arranged with zone circulators and no
bypass piping, the circulator provided with the boiler may
be used as a zone circulator. Both piping arrangements
allow the circulator to pump away from the expansion
tank and show how the piping should be arranged to
allow the heating system to be easily purged of air. The
circulator can be installed on the return side of the
boiler, if preferred.
