   careful, do not over-tighten.

8. Push the thermostat knob onto the thermostat shaft.

OPERATING INSTRUCTIONS

1. The heater must be properly installed before operation.
2. Rotate the thermostat knob fully clockwise. This should energize the heating elements and fan causing warm air to flow from the hot air discharge at the openings in the bottom of the grille. (see note 5)
3. After the operation check, rotate the thermostat knob to the desired position to obtain room comfort.
4. For continuous fan-only operation (heating elements will not be energized), slowly rotate the thermostat knob clockwise until you hear the fan operate (about 30 degrees from the OFF point).
5. There will be a short delay from the time the unit is turned on until the fan engages. This is to allow the elements time to warm up. The fan will also continue to run once the unit is turned off to allow the elements time to cool.

NOTE: For best results, the heater should be left “ON” constantly during the heating season because the thermostat, when properly set, will maintain the desired temperature.

How To Reset Manual Thermal Overheat Protector Control:
Your heater is equipped with a manual reset thermal overheat protector control that will automatically turn the heater off to prevent a fire if the heater 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.

WARNING
CAUTION – DO NOT CONTINUE TO ATTEMPT TO USE THE HEATER IF THE SAFETY CONTROL REPEATEDLY OPERATES AFTER BEING RESET. TO DO SO COULD PERMANENTLY DAMAGE THE HEATER OR CREATE A FIRE OR SAFETY HAzARD.

CAUTION
DO NOT TAMPER WITH OR BYPASS ANY SAFETY LIMITS INSIDE THE HEATER.
