WIRING

ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be effectively grounded in accor- dance with the National Electrical Code, NFPA 70.

All electrical wiring must be done by a qualified person in accordance with National Electrical Code (NEC) and meet all state and local regulations.

1.Use heater only at the voltage specified on the nameplate.

2.Branch circuit wire for connection to heater must be at least 90°C wire. Use copper conductors only.

3.The heater connection points are located in the gasketed termi- nal enclosure. To remove cover, remove 4 screws on the cover. Remove the cover to expose wiring connection points.

4.A green ground terminal is provided in the bottom of the enclo- sure. The ground wire should be connected before other con- nections are made.
