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

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.
