45. Line Voltage Wiring – High Amp Circ Pumps • PureFire main control has a max amp draw of 5 amps including gas valve & other internal loads. • Total amp draw of all operating Circulators must be less than about 4.5 amps. • For example the General Circulator + the CH Circulator or the DHW circulator must be less than 4.5 amps. • If the circulator amp draw is higher than 4.5 amps, it must be isolated using a relay. • A RIB2401B relay may be used for circulator motors up to 1 horsepower. • The wiring schematic below shows how to wire isolation relays to the circulators.
