Operation
1. Turn power to heater on at main switch panel. Rotate the
thermostat knob fully clockwise. This should energize the
heating elements and the fan, causing air to flow from the
air discharge at the openings in the bottom of the grille.
2. After the discharge air has become warm, rotate the
thermostat knob to the desired postion to obtain room
comfort.
NOTE:
For best results, the heater should be left ON con-
stantly during the heating season since the thermostat, when
properly set, will maintain the desired temperature.
IMPORTANT INFORMATION
Maintenance
TO RESET MANUAL RESET LIMIT
Your heater is equipped with a manual reset safety thermal
limit control that will automatically turn the heater off to pre-
vent a fire if the heater overheats. This control is located on
the fan panel assembly between the element and fan blade
and marked “reset”. The red reset button can be seen
through the front grille when the heater is installed. To reset,
allow the heater to cool, then push the red button that is vis-
ible through the hole in the fan panel. The heater should
immediately return to normal operation.
The heater should be cleaned annually to remove dust and
other foreign material which has collected during the heating
season. This is a simple operation when performed as fol-
lows:
1. Turn off the electric power at main line switch (or
remove all fuses) to disconnect electric power from the
heater. THIS IS IMPORTANT.
2. Remove the grille (Fig. 4).
3. With a vacuum cleaner nozzle or dust cloth, remove
dust and other foreign material.
4. After cleaning reinstall the grille.
5. Turn on the main line switch (or replace fuses) to
restore power to the heater. The heater is now ready
for another season of operation.
