OPERATING
INSTRUCTIONS
1. Heater must be properly installed before operation.
2. Rotate wall thermostat knob counterclockwise until control
stops. This is the minimum heat setting.
3. Turn power supply to heater “ON” at main switch panel.
4. Heater should not operate. If it operates, disconnect power
and re-check wiring.
5. Rotate wall thermostat knob clockwise until it stops (maxi-
mum heat setting) and wait at least 2 minutes. Fan control
will delay fan coming on until element is warm.
6. If heater and fan do not come on, disconnect power and
check wiring.
7. Allow heater to continue to operate until room temperature
reaches desired comfort level. Then rotate wall thermostat
knob counterclockwise slowly until thermostat clicks off. Fan
must continue to operate for a minute or so until element
cools. If fan turns off immediately when thermostat is turned
off, disconnect power and check wiring. (See Fan Delay
Notice).
8. It may be necessary to readjust thermostat a time or so until
exact comfort level is attained. Rotation in the clockwise
direction will increase the amount of time the heater will pro-
duce heat. Rotation in the counterclockwise direction will
reduce the amount of time the heater is on.
NOTE:
For best results, the heater should be left “ON” constant-
ly during the heating season as the thermostat, when properly
set, will maintain the desired temperature. In the full counter-
clockwise position the heater will remain off until the room tem-
perature drops well below freezing.
Operational Notice:
Your heater is equipped with an automatic reset over-tempera-
ture limit control that will automatically turn the heater off to pre-
vent a fire if the heater overheats. If heater cycles off on this con-
trol, a red alarm light will illuminate.
