Operation
1. Rotate the thermostat fully clockwise. This should
energize the heating elements and cause warm air to
flow from the hot air discharge at the openings in the bot-
tom of the grille.
NOTE: This heater is provided with a fan delay control that
allows the heating element to warm prior to the fan coming
on. This delay will also allow the fan to operate for a short
period after the heating element has been turned off to
remove the residual heat from the heater.
2. After the operation check, rotate the thermostat to
the desired position to obtain room comfort.
3. For continuous fan only operation (elements will not be
energized) rotate thermostat knob where indicator dot on
knob is aligned with "FAN".
NOTE: For best results, the heater should be left "ON"
constantly during the heating season because the thermo-
stat, when properly set, will maintain the desired tempera-
ture.

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.

SUBJECTED TO SOME ABNORMAL CONDITION. IT IS RECOM-
MENDED THAT THE HEATER BE CHECKED BY A REPUTABLE
