All heater models require constant 120 V 60 Hz 1Ø 
power supply. Check heater(s) 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 or ROBERTS GORDON
®
  
control 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.
9.1.1 Fan Control
The heater’s axial fan can be used during the off-
season for air circulation. A low voltage thermostat 
with fan control must be used. See Page 15, Section 
9.2
 for thermostat connection details.
