SPECIFICATIONS
Read all instructions before using this heater.
1.
Make certain that the power source conforms to the
electrical requirements of the heater. Disconnect power
before installing or servici
ng. If the power disconnect is out
of sight, lock it in the open position and tag it to prevent
unexpected application of power. Failure to do so could
result in fatal electric shock.
WARNING: DO NOT DEPEND UPON A THERMOSTAT OR
OTHER SWITCH AS THE SOLE
MEANS OF
DISCONNECTING POWER WHEN INSTALLING OR
SERVICING THE HEATER. ALWAYS DISCONNECT THE
POWER AT THE MAIN CIRCUIT BREAKER AS DESCRIBED
ABOVE. FAILURE TO DO SO COULD RESULT IN FATAL
ELECTRIC SHOCK.
2. This heater is intended ONLY for permanent installat

accordance with the National Electric Code (NEC), all
applicable local codes and ordinances, and all sections of
this manual. Any variance voids the warranty and may
create unsafe conditions. All wiring should be done by a
qualified electrician, using copper wire only.
3.
This heater is intended for general heating applications
ONLY. It must NOT be used in potentially dangerous
locations such as flammable, explosive, chemical-

IMPORTANT SAFETY INFORMATION
4.
Special attention must be given to any bonding (grounding)
information pertaining to this heater. To prevent the risk of
electrocution, the heater must be securely and adequately
bonded. This should be accomplished by connecting a
co

screw provided in the heater. To ensure a proper bond, the
bonding means must be tested by a qualified electrician.
5.
Do not insert fingers or foreign objects into the heater. Do not
block or tamper wi

touch heater while it is in operation or just after it has been
turned off, as some parts may be hot enough to cause injury.
6.
Do not attach ductwork to this heater or attempt to use it as a
make-up air heater
. Such use voids the warranty and may
create unsafe conditions.
7.
In cases where property damage may result from malfunction
of the heater, a back-
up system or a temperature alarm
should be used.

at
voltages no higher than the heating elements and the heater are
designed for. (Lower voltages, however, pose no problem other
