Maintenance As Needed, or every six months minimum.
WARNING! Before removing grill, turn the electrical power off at the electrical panel
board (circuit breaker or fuse box). Lock or tag the panel board door to prevent someone
from accidentally turning the power on while you are working on the heater. Failure to do
so could result in serious electrical shock, burns, or possible death.
WARNING: Any other service not detailed in this Owner's Guide should be performed by an autho-
rized service representative.
1. It is important that you verify power has been turned off and no
power is going to the heater before proceeding. Circuit breakers
are often not marked correctly and turning the wrong breaker off
could mean electricity is flowing to the heater, even if the heater
does not appear to be working. If you are uncomfortable working
with electrical appliances, unable to follow these guidelines, or do
not have the necessary equipment, consult a qualified electrician.
2. Once you verify the power has been turned off correctly, pro-
ceed to the next step.
3. Remove thermostat knob (if any), screws and take off grill.

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.
4. Wash grill with hot soapy water and dry immediately.
5. While holding fan (to avoid damage or bending), use a hair dryer
or vacuum on blow cycle to blow debris through the top element
(do not touch element).
6. Vacuum fan area without touching the elements.
7. Do not lubricate motor.
8. Replace grill and secure with screws. Replace thermostat knob.
9. Turn thermostat to desired setting.
10. Turn power back on at the electrical panel board.
