heaters. Studying the instructions first may save you considerable time and money later. Observe the following procedures and cut your installation time to a minimum. To reduce
risk of fire or 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 as
a precaution against possible electric shock.
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.
WARNING
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.

exhaust in any manner. Keep combustible materials, such
as crates, drapes, etc., away from heater. Do not install
behind doors, furniture, towels, or boxes.
7. A heater has hot and arcing (sparking) parts inside. Do
not use it in areas where gasoline, paint, or flammable
liquids are used or stored.

Installation of Heater Assembly and Grille
NOTE: Field wiring to heater is through line voltage
thermostat (supplied by others).
Operation
The heater is intended to be turned on and off by a remote line
voltage thermostat or some other controlling means suitable
for interrupting power to the heater.
1. Turn power to heater on at main switch panel. Turn
remote line voltage thermostat to demand heat. This
should energize the heating elements causing convective
heated air to flow from the air discharge grille on the top
face of the grille. This may take a minute to be noticeable
and will increase in temperature with time.
2. After the discharge air has become warm and room conditions become comfortable, adjust the remote wall thermostat to the desired position to obtain room comfort.
IMPORTANT INFORMATION
Cleaning and Maintenance
The heater should be cleaned annually to remove dust and
other foreign material that has collected during the heating
season. This is a simple operation when performed as follows:
1. Turn off the electric power at main line switch (or remove
all fuses) to disconnect electric power to the heater. THIS
IS IMPORTANT.
2. Remove the grille (Figure 4).
3. With a vacuum cleaner nozzle or dust cloth, remove dust
and other foreign material from the heater and grille.
4. After cleaning, reinstall the grille.
5. Turn on the main line switch (or replace fuses) to restore
power to the heater. The heater is now ready for another
season of operation.
6. The exterior surfaces should be wiped down with clean
damp cloth. Avoid using harsh solvents and products
leaving oil or wax residue.
1. Plug heater assembly into mating socket in back box
wiring cover. The plug and socket are “position sensitive”
so care should be taken regarding orientation. Attach
heater assembly to back box using the four screws used
during removal.
2. Mount front grille by aligning the two grille tabs with the top
slots in the heater frame assembly. Attach the bottom of
the grille to the heater frame assembly using the screw
provided (taped to the front bottom of the heater frame.)
