TO RESET MANUAL RESET LIMIT:
Your heater is equipped with a manual reset safety thermal limit control
that will automatically turn the heater off to prevent a fire if the heater over-
heats. This control is located on the fan panel assembly between the ele-
ment 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.
