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
authorized service representative.

or lint particles.
4. Overheating due to location elevation
above 7500 feet.
5. Power outages or interruptions.
1. Check all clearance requirements.
2. Discontinue use of breaker to control heater, or replace time delay
relay. Push both manual reset limit buttons in front (See “Operating”

5. Power to heater needs to be constant. Push both manual reset limit
buttons in front (See “Operating” section for instructions).
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 owing 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 qualied electrician.
2. Once you verify the power has been turned off correctly, pro-
ceed to the next step.
3. Remove front diffuser grill or 3 of the center louvers in front of
fan area.
4. Using a compressor, blow air through the outer cabinet louvers
and nned element areas. (Do not touch sharp surfaces on
elements). While holding fan blade (to avoid damage or bending)
carefully blow inside the fan motor area.
5. Carefully wipe off the fan blade without damaging or bending it.
6. Reinstall front diffuser grill or 3 of the center louvers.
7. Turn thermostat to desired setting.
8. Turn power back on at the electrical panel board.
