CIRCULATOR PUMP SPECIFICATIONS

1.Maximum operating pressure for the pump must exceed system operating pressure.

2.Maximum water temperature should not exceed nameplate rating.

3.Cast iron circulators may be used for closed loop systems.

4.A properly sized expansion tank must be installed near the boiler and located on the suction side of the pump.

CIRCULATOR PUMP OPERATION

(Heating Boilers Only)

Boilers are equipped with a relay for controlling the circulation pump for the hot water loop. The relay turns ON and OFF in response to the “W” input from the wall thermostat or zone control.

The field installed boiler pump MUST NOT exceed 1 h.p. For continuous pump operation, wire the system pump to the 120V supply. The pump should be connected at the junction box as shown in Figure 41.

PUMP INSTALLATION AND MAINTENANCE: The boiler circulating pump must be purchased locally. For installation and maintenance information on the circulator pump, refer to the pump manufacturers instruction package included with the pump.

BYPASS PUMP 45,000 - 260,000 Btu/hr

(Heating Boilers Only)

These units are equipped with an integral bypass pump, which is designed to provide efficiency optimization by maintaining a constant flow through the unit’s heat exchanger loop when building system flow is reduced. The bypass pump assembly is standard equipment and is NOT to be used as a system pump.

NOTE:

The bypass pump is dedicated to the unit and does not affect the building’s system or primary/secondary flow characteristics and will not circulate the building.
