Wiring
Heaters are normally controlled by thermostats. Line voltage
thermostats are wired directly (see Figure 15), 24V thermostats
are wired directly by finding and removing the jumper wire on the
back of the burner box and wiring the thermostat to the terminals
(see Figure 16). Heaters must be grounded in accordance with the
National Electric Code ANSI/NFPA- 70 or current Canadian Electrical
Code, CSA C22.1. Heaters may also be controlled with a manual line
voltage switch or timer switch in place of the thermostat.
