  22. Caution – Before cleaning, or storage, or when not in use, turn the product’s controls to the OFF position and unplug the heater from the electrical outlet and allow to cool.
  23. Caution – Place the heater on a firm, level, open surface free from obstructions and at least 3 feet (0.9 m) away from any combustible materials. DO NOT use on an unstable surface such as bedding or deep carpeting. Be sure the heater is not in a position where it may be a tripping hazard.
  24. Caution – If your home has aluminum wiring have a licensed electrician check your receptacle’s connections. When using a 1500 watt heater, aluminum wire connections can cause a safety issue.


Ceramic heaters generate heat by passing electricity through heating wires embedded in ceramic plates. This type of heating technology provides fast, even heating.
The Thermawave™ 6 Heater was designed for maximum heat output.


This heater requires simple, no tool assembly. Unpack Main Body and Mounting Base (Fig. 1). Place Mounting Base on a firm surface. Place ThermaWaveTM 6 Heater Main Body on Mounting Base so Mounting Tabs are aligned with Base Slots. Press Main Body onto the Base until Tabs snaps secure into the Slots (Fig. 2).


Place the heater on a firm, level, open surface free from obstructions and at least 3 feet (0.9 m) away from any wall or combustible material. DO NOT use on an unstable surface such as bedding or deep carpeting.
For best result, place heater on the floor to create warming room convection and allow heater to run for 5-10 minutes to reach maximum heat output.


  • Turn off the heater.
  • Allow it to cool for ten (10) minutes.
  • Unplug heater and move. This heater is equipped with a Cool Touch Handle for your convenience.


NOTE: NEVER LEAVE AN OPERATING UNIT UNATTENDED With the Power Button in the OFF position, plug the heater into a polarized 120V outlet. DO NOT FORCE THE POLARIZED PLUG INTO THE OUTLET; it will only fit one way. The ThermaWaveTM 6 Heater is versatile and designed to be placed in the center of the room or closer to the wall (at least 3 feet away) for maximum convection room heating. ThermaWaveTM 6 Heater Operation Turn heater on by pressing ON  button. The heater will default to the low setting. Adjust Louver to give directional heat control. To turn the unit off, press the power until none of the heat settings are illuminated and the red power light is off.

The Settings Button is equipped with three settings: Fan Only . The to accommodate your comfort level with the Settings Button ( ). Press the button until the setting you want is illuminated. The Low heat setting does not require as much electricity to operate, it is more energy-efficient and may be a better option if you are concerned about amperage draw on a circuit when the heater is on the High setting. The Adjustable Thermostat  button is equipped with 4 pre-set Heat Levels. To set Thermostat to one of these levels, press the Thermostat button until the temperature desired is illuminated. The heater will operate at the High setting until the room reaches the desired temperature. The heater fan will run for 60 seconds and turn off until the room temperature goes below desired temperature it will then turn back on.
The Timer Button is equipped with three settings: two hours (2h) four hours (4h) ) and eight hours (8h). The timer option will illuminate once selected. The timer is not on if none of those three (3) timer settings are illuminated.


The ThermaWave™ 6 Heater is equipped with several devices and features for added protection:

  • A 360º tip-over switch that disables the heater if it is tipped in any direction.
  • Two high-temperature safety sensors prevent overheating. If activated, unplug the device and wait at least 20 minutes or allow the unit to cool completely. Make sure the operating conditions are safe and then plug the heater back in and follow the OPERATION instructions.
  • Thermally insulated wiring for heat resistance and reinforced wire connections to help protect against loose connections.
  • Built using a high-temperature plastic and has a cool-to-touch housing and handle.

If your ThermaWave™ 6 Heater shuts off unexpectedly or fails to operate, one of your heater safety features may have been activated to prevent overheating.

  • Be sure it is plugged in and that the electrical outlet is working.
  • Check for any obstructions. If you find an obstruction, turn the heater OFF and unplug it. Allow the heater to cool completely, then remove the obstruction. Wait at least 20 minutes, then plug the heater back in and follow the OPERATION instructions. Make sure the heater is on a flat level surface so that the tip over switch is not engaged.

Operation Cost*
To estimate the cost to operate this heater, multiply the watts used by 0.001 to convert into kilowatts then multiply the kilowatts used by your local kilowatt-hour electric rate for however long you run the heater. For example, if your electric rate is $0.1326** per kilowatt-hour and you ran this heater in constant high mode (1500 watts) for 4 hours, it would cost you $0.80 cents to run the heater (1500 watts x 4 hours x 0.001) x $0.1326 kwp = $0.80 cents).
NOTE: The Low setting does not require as much electricity to operate, it is more energy-efficient and may be a better option if you are concerned about the higher power consumption when the heater is on the High setting.
