WIRING

WARNING: Hazard of Shock. Disconnect all power before working on boiler. Boilers must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

WARNING: Use 90˚copper conductors only.

1.Select proper wire gauge and type for supply conductors in accor- dance with the National Electrical Code and local wiring codes fol- lowing wiring diagram supplied (See recommendations for dis- connect switches and fusing).

2.The unit is completely wired and pre-tested before shipment. No internal wiring is required. Check all electrical connections for tightness and retighten if necessary before energizing.

If a separate control circuit is used, the control circuit should be connected to the control terminal block, inside access door (not required with transformer).

3.Safety Switches — WARNING: Purchaser should use a safety switch employing circuit breakers or fuses between his main power source and the boiler.

4.Because of their water lines, boilers are susceptible to lightning

damage. Industrial type lightning protectors should be installed per manufacturer’s recommendations at your service entrance. Check your contractor or electrical dealer for recommended type for your system.

5.Be sure all electrical connections are sufficiently tightened.

6.WARNING: Substitution of components or modifica- tion of wiring system voids the warranty and may lead to dangerous operating conditions.

7.SPECIAL INSTRUCTIONS FOR CUSTOMERS SUPPLY- ING THEIR OWN CONDENSATE OR PUMP SYSTEMS.

A.Check the voltage of the motor before making the wiring con- nection. Some Chromalox boilers are supplied with dual volt- age systems. The motor should always match the voltage of the control circuit.

B.The motor circuit should be wired into the pump control as shown in wiring diagram (float type pump control). If boiler is equipped with solid state pump control, refer to wiring diagram and use terminals 5 and 2.
