MAKING THE ELECTRICAL CONNECTIONS

Refer to Fig. #9227 Wiring Connection, and Fig. #9233 or Fig. #9234 Wiring Diagram.

1.Verify circuit breaker is properly sized by referring to boiler rating plate. A dedicated circuit breaker should be provided.

2.Turn off all power to the boiler. Verify that power has been turned off by testing with a volt-ohm meter prior to working with any electrical connections or components.

3.Observe proper wire colors while making electrical connections. Many electronic controls are polarity sensitive. Components damaged by improper electrical installation are not covered by warranty.

4.Provide an external surge suppressor capable of maintaining system integrity.

5.Provide overload protection and a disconnect means for equipment serviceability as required by local and state code.

6.Install boiler controls, thermostats, or building management systems in accordance with the applicable manufacturer’s instructions.

7.Conduit should not be used as the ground. There must be a solidly wired ground.

NOTICE:

A grounding electrode conductor shall be used to connect the equipment grounding conductors, the equipment enclosures, and the grounded service conductor to the grounding electrode.
