SECTION 10: WIRING
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 46,
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. Heaters must be grounded in accor-
dance with applicable codes: United States: refer to
National Electrical Code
®
ANSI/NFPA 70 - latest revi-
sion Canada: refer to Canadian Electrical Code CSA
C22.1 Part I - latest rev ision.
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.
