GROUNDING AND OPERATING INSTRUCTIONS
Prior to operating the heater, ensure the electrical receptacle is of the configuration and capacity appropriate
for the heater. See receptacle configuration in OPERATING INSTRUCTIONS. This heater is for use on 240 volts. The cord has a plug as shown in #6 above. The type of receptacle is a 240-volt grounding receptacle (NEMA 6-30R).

YOUR HEATER IS EQUIPPED WITH A THERMOSTAT:
- Turn the unit ON by turning the thermostat dial away from the OFF position.
- For faster heat-up or to increase the heat output, turn the Thermostat Control knob all the way to the right [MAX].
The thermostat function controls the temperature output. To decrease the heat output, turn the knob counterclockwise. - Once the room reaches the desired temperature, slowly turn the Thermostat Control knob counter clockwise until you hear a “click.” This sets the heater to cycle ON/OFF to maintain the desired heating temperature for energy efficiency.
- To completely shut off the unit, turn the thermostat dial to the OFF position and unplug the heater.
