CAUTION - TO REDUCE RISK OF FIRE AND
ELECTRIC SHOCK:
1. Disconnect all power coming to heater at main service panel
before wiring or servicing.
2. All wiring must be in accordance with the National and Local
Electrical Codes and the heater must be grounded.
3. Verify the power supply voltage coming to heater matches the
ratings printed on the heater nameplate before energizing.
4. This heater is hot when in use. To avoid burns, do not let bare
skin touch hot surfaces.
5. Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock, fire, or
damage to the heater.
6. Grille and discharge air are hot when in use. Do not install or use
heater in any area where airflow from heater may be blocked or
obstructed. Do not install behind doors, furniture, towel racks,
curtains, or boxes. Hot air may damage certain fabrics and plas-
tics. Always keep electrical cords, beddings, crates, drapes, and
other combustibles away from heater. Do not install heater in

7. A heater has hot and arcing or sparking parts inside. Do not use
it in areas where gasoline, paint, or flammable liquids are used
or stored.

not recommended by the manufacturer may cause fire, electric
shock, or injury to persons.
