1. Turn off power at the main disconnect panel.
2. Wait for the heater to cool.
3. Remove knob (if any) and grill.
4. Wash grill with hot soapy water and dry.
5. Blow air through the heating element with a hair dryer or shop vacuum
on blow cycle.
Any service other than cleaning should be performed by an authorized service representative.

MAINTAINING YOUR HEATER
Troubleshooting Chart
ELECTRICAL SERVICE PERSONNEL.
1. Verify that supply voltage matches the heater rating.
2. The total amperage of all heaters on a branch circuit must not be more than
80% of the amperage rating of the circuit breaker and supply wire ratings. Use a
lower wattage heater, or reduce the number of heaters on the circuit.
3. Shorted supply or heater wires may be accompanied by severe sparking.
Inspect all supply and heater wiring insulation for damage. Do not reset the circuit
breaker until all electrical shorts have been repaired.
4. Replace the circuit breaker.
1. Allow a few moments for element to reach operating temperature.
2. Verify that supply voltage matches the heater rating.
3. Replace element.
1. Close doors and windows. Provide additional insulation, or install a higher
wattage heater or multiple heaters if necessary. (If your circuit is rated for more
capacity.)
2. Adjust thermostat to its lowest setting. If heater continues to run (allow two
minutes for the thermostat to respond), and room temperature is greater than 50˚;
replace the thermostat.
3. Refer to thermostat documentation and correct wiring.
1. Clean heater (see "Maintenance" section above for instructions).
2. Turn off power at circuit breaker. Inspect all supply and heater wire connections
to make sure nothing is loose or poorly connected. Secure or reconnect all loose
connections. Do not reset circuit breaker until all connections have been checked
and repaired.
1. Heater or fan motor requires replacement.
2. Remove obstruction and press heater manual reset button (see "Operating"
section for instructions).
1. Adjust thermostat to a higher temperature until heater operates (see Problem #6
if the problem persists).
2. Press the manual reset button (see "Operating" section for instructions).
3. Position grill so louvers do not press against manual reset button.
4. Turn on the correct circuit breaker in the main panel.
5. Turn off power at circuit breaker. Check supply wire continuity and proper con-
nection to heater wires.
6. The entire heater, or any of its components may be checked for continuity to
determine the cause of any problems. Repair or replace the heater or thermostat.
1. Clean heater (see "Maintenance" section for instructions).
2. Remove obstruction. Maintain a minimum distance of 6 inches from adjacent
surfaces, 4.5 inches from the floor, and 3 feet from furniture or other objects
placed directly in front of the heater.
3. Remove obstruction, and press heater manual reset button (see "Operating"
section for instructions).
4. Replace heater assembly.
6. Clean the fan with a vacuum cleaner.
7. Replace grill and knob (if any).
8. Turn power back on at the main disconnect panel.
