ventilated during this operation. It is normal for the appliance to emit
small crackling sounds when you turn it on for the first time. Do not
be alarmed.

OPERATING INSTRUCTIONS
HAZARD OF ELECTRIC SHOCK, EXPLOSION
OR ARC FLASH:
Apply appropriate personal protective equipment (PPE)
and follow safe electrical work practices. See NFPA 70.
A circuit breaker must be installed and serviced only by a
certified electrician.
Always use a properly rated voltage sensing device to
confirm that the power is OFF.
The HIGH/LOW switch on the heater is only for setting
selection. Use the circuit breaker as the Power
ON/OFF switch for the heater. The circuit breaker is
to be installed by a certified electrician and should be
located in line-of-sight from the heater location, or it
should be capable of being locked in the open
position. Follow the operating instructions to reduce
the risk of fire, electric shock, injury, or death.
To turn on the heater, switch on the circuit breaker.
Then turn the thermostat to the farthest clockwise position. The
fan should start, the unit will begin heating the room, and the
lamp will light.After the room reaches a comfortable level, turn
the thermostat counterclockwise until the heater shuts off. The
heater will cycle automatically around this preset temperature.
To increase the temperature, turn the thermostat knob
clockwise. To lower the temperature, turn the thermostat
counterclockwise.
Toggle the HIGH/LOW switch to change the heat setting.
HIGH: 6000W
LOW: 3000W
Select a thermostat setting.
12
Ambient temperature is regulated by adjusting the thermostat to a
desired position. Allow the unit to operate and warm up the room.
When the desired temperature is reached, turn the control knob
counterclockwise until the heater turns off. This is your ideal setting.
The heater will start automatically when the room temperature
drops below this set point, and will turn off when the set point is
reached.
To turn off the heater, switch off the circuit breaker. The
circuit breaker serves as the only means of disconnecting
power from the heater.
This heater includes a visual alarm to warn that parts of the
heater are becoming excessively hot. If the alarm flashes,
immediately turn the heater OFF and inspect for any objects on,
in, or adjacent to the heater that may cause high temperatures.
DO NOT OPERATE THE HEATER WITH THE ALARM
FLASHING. To reset the heater, switch the circuit breaker OFF,
and wait five to ten minutes for the unit to cool down before
turning the heater on again.
