WIRING

WARNING: Hazard of Shock. Any installation involving electric heaters must be effectively grounded in accor- dance with the National Electrical Code.

1.Electric wiring to heater must be installed in accordance with the National Electrical Code and with local codes by a qualified person as defined in the NEC. WARNING: Use copper con- ductors only.

2.When element wattages are not equal, heaters must not be connected in series.

3.Electrical wiring to heater should be contained in rigid con- duit or in sealed flexible hose to keep corrosive vapors and liq- uids out of the terminal housing.

4.If flexible cord is employed, a watertight connector should be used for entry of the cord into the terminal box. Outdoor applica- tions require liquid-tight conduit and connectors.

5.Bring the power line wires through the opening in the terminal box. Connect line wires as shown in the wiring diagram (see Figure 5).
