About the Manual Reset Temperature Limit Control 
The heater is protected by a temperature-limiting control. The 
manual reset temperature limit control is designed to open the 
heater circuit and stop the electrical current ow when exces-
sive operating temperatures are detected. The problem must be 
assessed and the limit must be reset to resume operation.
Resetting the Manual Reset Temperature Limit Control
If the manual reset limit control has opened the heater circuit due to excessive operating temperatures, the heater will not work until 
the manual reset limit button is pressed. After allowing the unit to cool for at least 10 minutes and resolving the problem causing the 
limit to trip (typically the heater is blocked or needs cleaning-see “MAINTAINING YOUR HEATER”); use a narrow object such as a 
ball-point pen to access the manual reset button through the lower-right center section of the heater grill. Press FIRMLY and be sure to 
listen and feel for a click, indicating it has been reset.
How to operate your heater
The room temperature is controlled by a line voltage thermostat 
located either on the wall or built-in to the heater.
1. Once installation is complete and power has been restored, 
turn the thermostat knob fully clockwise.
2. When the room reaches your comfort level, turn the thermo-
stat knob counterclockwise until the heater turns off. The heater 
will automatically cycle around this preset temperature.
3. To reduce the room temperature, turn the knob counterclock-
wise. To increase the room temperature, turn the knob clockwise.
 WARNING Risk of Electrical Shock and Fire.
The heater must be properly installed before it is 
used.
1. Do not operate without grill.
2. Keep electrical cords, drapery, furnishings and 
other combustibles at least 3 feet away from the 
front of the heater and 6 inches away from the 
sides.
3. Do not tamper with the over temperature limit 
control.
4. If the heater over temperature limit trips more 
than once per day, the heater must be replaced.
5. Clean heater at least every six months.
6. After allowing the heater to cool, turn power off 
at circuit breaker panel before removing grill.
7. Use a hair dryer or vacuum on blow cycle to 
blow debris through the top element (do not touch 
element).
8. Install the grill before turning on power.
    WARNING:  Any other service not detailed in 
this Owner’s Guide should be performed by an 
authorized service representative.
