This heater features an over-temperature safety control that will turn off the heater if
it overheats. This control is located on the fan panel assembly between the element
and fan blade and marked “reset”. The red reset button can be seen through the front
grille when the heater is installed. To reset, allow the heater to cool, then push the red
button that is visible through the hole in the fan panel. The heater should immediately
return to normal operation.
