All heater models require constant 120 V/1Ø/ 60 Hz
power supply. Check heater rating plate for electrical
rating for proper circuit sizing. For servicing, a
disconnect switch of proper electrical rating should
be installed in the vicinity of the heater.

All heaters are equipped with thermostat
connections suitable to power a 24 V thermostat.
Heater must be wired and electrically grounded in
accordance with local codes. In the absence of local
codes in accordance with: United States: refer to
National Electrical Code

NFPA 70 - latest revision;

Canada: refer to Canadian Electrical Code CSA
C22.1 Part I - latest revision.

9.1 Positioning Thermostats
A room thermostat should be mounted on a
vibration-free wall or column at a height of
approximately 5' (1.5 m) from the floor to measure
the ambient temperature. It should be clear of both
cold drafts and the direct path of warm air from the
heater.
Avoid mounting thermostat on outside walls or in
areas directly exposed to radiant heat or sunlight.
Install wall tag in a visible location near thermostat.
See Page 2, Section 2.1 for wall tag details.
