MAINTAINING YOUR HEATER
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.
*CONSULT LOCAL ELECTRICAL CODES TO DETERMINE WHAT WORK MUST BE PERFORMED BY QUALIFIED
ELECTRICAL SERVICE PERSONNEL.
Heater is working,
but room does not
reach desired tem
-
perature.
1. Heat loss from room is greater than
heater capacity.*
2. Furniture or other surfaces may be too
close to the heater.
3. Verify if temperature lock has been set.
Thermostat setpoint is 40-90 degrees.
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. Remove furniture or other surfaces to appropriate clearances, so air can flow
freely throughout room. 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. See “Maximum Temperature Lock” on page 6.
Breaker trips
immediately upon
energizing heater.
1. Overloaded circuit.*
2. A short circuit exists in the supply or
heater wiring.*
3. Defective circuit breaker.*
4. Thermostat malfunction.
1. 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.
2. 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.
3. Replace the circuit breaker.
4. Replace heater assembly.
Heater fan oper-
ates, but does not
discharge warm air.
1. Rocker switch is not set to HEAT mode.
2. Element has failed.*
1. Turn rocker switch to HEAT mode.
2. Replace element.
Heater will not shut
off.
1. Heater continues to run at low speed.
2. Heat loss from room is greater than
heater capacity.*
3. Thermostat is not functioning properly.
1. If room temperature is being regulated and maintained, a low fan speed and low
heat output is normal for this energy saving heater.
2. 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.)
3. Replace heater assembly.
Heater discharges
smoke or emits a
burnt odor.
1. Dust, lint or other matter has accumu
-
lated inside heater.
2. Poor or loose electrical connections.
1. Clean heater (See “Maintaining Your Heater” section for instructions).
2.Turn off power at circuit breaker. Inspect all supply and heater wires for loose or
poor connections. Secure or reconnect all loose connections. Do not reset circuit
breaker until all connections have been checked or repaired.
Element heats for
a moment without
the fan turning, then
immediately stops
heating.
1. Defective motor or internal connection.*
2. Fan is jammed.
1. Heater or fan motor requires replacement.
2. Remove obstruction and confirm that fan is spinning freely. Press reset button
per the “Maintaining Your Heater” section.
Heater does not
run.
1. Thermostat is set too low.
2. Rocker switch is set to “NO HEAT”.
3. Heater has tripped the manual
high-temperature reset switch.
4. Power not on at the circuit breaker.
5. Broken or poorly connected wire(s) to
heater.
6. Defective thermostat.
7. Circuit breaker not installed correctly.
1. Adjust thermostat to a higher temperature until heater operates (See Problem
#6 if the problem persists).
2. Switch rocker switch to “HEAT” mode.
3. Press the manual reset button (See “Maintaining Your Heater” section for
instructions).
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. Repair or replace the heater assembly.
7. Correct the circuit breaker installation.
Heater continually
trips the manual
reset temperature
limit control.
1. Dust, lint or other matter has accumu
-
lated inside heater.
2. Airflow is blocked.
3. Fan or motor is jammed.
4. None of the above.
1. Clean heater (See “Maintaining Your Heater” 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 “Maintaining
Your Heater” section for instructions).
4. Replace heater assembly.
Maintenance As Needed, or every six months minimum.
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 screws and take off grill.
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.
9. Turn thermostat to desired setting.
10. Turn power back on at the electrical panel board.
