SECTION 10: WIRING
DANGER
Electrical Shock Hazard
Disconnect electric before service.
Heater must be properly grounded.
Failure to follow these instructions can result in death or electrical shock.
Heaters can be controlled using several methods. Normally thermostats are used to control the heaters but they can also be controlled by an Energy
Management System. Section 10.1 below illustrates the connection for heaters controlled by a line voltage thermostat. NOTE: In order to use line voltage ther- mostats, the low voltage terminal located at the back of each burner must be connected as shown in the detail. For a single heater on a low voltage thermo- stat, See Section 10.2 below. To control multiple heaters on one low voltage thermostat, See Page 43, Section 10.3. NOTE: In order to control multiple heat- ers on one low voltage thermostat, the low voltage terminals on each heater must be connected as shown in detail. Heater must be grounded in accor- dance 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 V.
