l A heater has hot arcing or sparking parts inside. Do not use in areas where gasoline, paint,
flammable vapors, or liquids are used or stored.
l Use this heater only as described in this manual. Any other use not recommended by the
manufacturer may cause fire, electric shock, or injury to persons.
l This heater may include an audible or visual alarm to warn that parts of the heater are getting
excessively hot. If the alarm sounds (or illuminates), immediately turn the heater off and inspect
for any objects on or adjacent to the heater that may have blocked the airflow or otherwise
caused high temperatures to have occurred. DO NOT OPERATE THE HEATER WITH THE
ALARM SOUNDING (OR ILLUMINATING).
l ALWAYS plug heaters directly into a wall outlet/receptacle. NEVER use with an extension
cord or relocatable power tap (outlet/power strip).
l NEVER use this heater in bathrooms, laundry rooms, or any other location where the heater
could fall into a bathtub, pool, become damp, or come in contact with water.
