The CPSC says the heater design can fail to prevent ignition of nearby combustible materials that come in contact with the unit, posing a fire hazard.
This recall involves two models of Optimus Infrared Quartz Radiant heaters with model numbers H-5210, produced in 2011 and H-5211, produced in 2012.
The model number and the year of production appear on a label on the back of the heater.
The recalled heaters are white and are approximately 12-inches wide, by 13-inches tall, by 6-inches deep.
"Optimus" is printed on the top left of the heater.
The control knob is located on the top right side of the heater.
