Read Carefully - These instructions are written to help you prevent
difficulties that might arise during installation of 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 AND ELECTRIC SHOCK:
1. To prevent electrical shock, 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.
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. To prevent a possible fire, do not block air intakes or exhaust in
any manner. Keep combustible materials, such as crates,
drapes, etc., away from heater. Do not install behind doors, furniture, towels, or boxes. Do not install in ceiling.
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.
8. 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.
9. This heater is not approved for use in hazardous or corrosive
atmospheres, such as marine, green house, or chemical storage
areas.

• Supply may enter heater back box from wall through back
knockout or through top knockout when surface type conduit is provided. When surface conduit system is used, the
“U” shaped knockout in the surface frame must be removed
to allow clearance over conduit.
a. Remove the disconnect switch bracket from back box by
removing the two screws.
b. Remove desired knockout in rear or top of back box and run
supply cable to heater location and into upper right corner of
back box, leaving at least 6” of wire inside box for connection.
Cable arrangement must be in accordance with the National
and Local Electric Codes and cable must be properly protected by use of appropriate cable clamp or conduit fittings.
c. Referring to the appropriate wiring diagram make the follow-
ing connections:
1. Connect the supply ground conductor to the back box by
attaching to the grounding lug marked “Ground.”
2. Connect each supply power lead wire to one of the blue
lead wires from the disconnect switch using wire nuts or
approved wire connectors.
3. If black leads from disconnect switch are not already
attached to terminal block attach as shown in the wiring
diagram. Check to make sure connections are tight.
4. Secure disconnect switch and bracket to back box with the
screws removed earlier.
3. Carefully fit surface frame over back box making sure back
edges of frame are flush with finished wall. See fig. 3. Secure
frame in place with two screws as shown.
Installation of Heater Assembly and Grille
After back box is completely installed and no further construction
dirt is expected, clean debris from back box. Heater fan panels
were shipped mounted to back box and were removed to mount
back box.
1. Insert the heater assemblies (fan panels) into back box, placing the four mounting holes (with key-hole slots) over the
screws in the back box. Tighten all screws securely.
2. If surface-mounting frame is used, ensure that the
frame is even with all four heater assembly tabs before
tightening screws.
3. Connect the two disconnected black switch wires to the
heater terminal block (see wiring diagram). Connect red, blue
and black wires from both fan panels to heater terminal
block (see wiring diagram). Check that all wiring connections are tight.
4. Turn thermostat(s) to the extreme counterclockwise position.
5. Turn disconnect switch “ON”.
6. Mount the grille using the six (6) long screws provided.
The screws thread into holes located in the flanges of the
back box.
Operation
NOTE: The operation instructions apply to 208, 240 and 277V
heaters with one thermostat. Units operating at 347V, 480V and
600V have
two thermostats.

1. Rotate the thermostat(s) fully clockwise. This should energize
the heating elements and, after a short delay, engage the
fan causing warm air to flow from the hot air discharge at the
openings in the bottom of the grille.
2. After the operation check, rotate the thermostat(s) by inserting
a small screw driver through the grille to the desired position
to obtain room comfort. For units with two thermostats, it is
recommended that both should be set at approximately the
same setting.
NOTE: For best results, the heater should be left “ON” constantly
during the heating season because the thermostat, when properly
set, will maintain the desired temperature.
TO RESET MANUAL RESET LIMITS
Y our heater is equipped with two manual reset safety thermal limit
controls that will automatically turn the heater off to prevent a fire if
the heater overheats. These controls are located on the fan panel
assemblies between the elements and fan blades and marked
“reset”. The red reset buttons can be seen through the front grille
when the heater is installed. T o reset, allow the heater to cool, then
push the red buttons that are visible through the hole in the fan
panels. The heater should immediately return to normal operation.
Determine why manual reset tripped! (See Caution note)
Maintenance
Once each year the heater should be cleaned to remove dust
and other foreign material which 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 from the heater. THIS IS
IMPORTANT.
2. Remove the grille and turn the disconnect switch to the OFF
position.
3. With a vacuum cleaner nozzle or dust cloth, remove dust
and other foreign material.
4. After cleaning, turn disconnect switch to ON position and
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.
OPERATION OF THE MANUALRESET SAFETY THERMALLIMIT CONTROL IS AN INDICATION THAT THE HEATER HAS BEEN SUBJECTED
TO SOME ABNORMALCONDITION. IT IS RECOMMENDED THATTHE
HEATER BE CHECKED BY A REPUTABLE ELECTRICIAN OR REPAIR
SERVICE TO ENSURE THE HEATER HAS NOT BEEN DAMAGED.
DO NOT USE WATER OR DAMP CLOTH FOR CLEANING AND DO
NOT DISTURB THE HEATING ELEMENT.
