Dimplex ceiling heaters are designed and tested for safe and
trouble-free operation. All Dimplex ceiling heaters are pro-
14400
tected against overheating by a built-in thermal cutout. Free
airflow throughout the heater is extremely important for the
most efficient operation of the heater. Restricted airflow may
cause the thermal overload protector to cycle the heater "ON
and OFF". A cycling heater will not supply sufficient heat to
the room.
CAUTION: Avoid direct contact of paper, fabric, or furni-
ture with heater.
