Heater must be grounded in accordance with applicable codes: United States: refer to National
Electrical Code® NFPA 70 - latest revision Canada: refer to Canadian Electrical Code, CSA C22.1 Part I - latest revision.
If any of the original internal wiring must be replaced, it must be replaced with wiring materials having a temperature rating of at least 105°C and 600 Volts.
10.1 Standard Heater Configuration
From the factory, the heater is configured for zone sensor control. Connect zone sensor to the heater control as shown on Page 39, Figure 22.
If additional heaters are in the same heating zone, control wiring must be installed between the heaters’ controls as shown on Page 39, Figure 22.
For additional details or for use with heat demand control devices other than the zone sensor, see Page 40, Section 10.2 through Page 48, Section 10.4.9.
