always be followed to reduce risk of fire, electrical shock and
injury to persons or property, including the following:
Please read all instructions before using this heater.
NOTE: This product must be installed by a certified electrician
in accordance with local codes.
Traces of smoke or odor when unit is initiated indicates that small
amounts of oil leaked on heating coil during manufacturing. It will
evaporate quickly and should not re-occur. Make sure the appli-
ance location is well ventilated during operation. It is normal for the
unit to emit sounds when turned on for the first time.
Make sure that the room in which the appliance is located is well
ventilated during this operation.
1.Read all instructions before using this heater.
2.This heater is hot when in use. To avoid burns, do not let
bare skin touch hot surfaces. Keep combustible materials,
such as furniture, pillows, bedding, papers, clothes and
curtains at least 3 ft. (0.9 meters) from the front and top of the
heater and keep them away from the sides and rear.
3.Extreme caution and reasonable supervision is necessary
when any heater is used by or near children, invalids or pets
and whenever the heater is left operating and unattended.

been dropped or damaged in any manner. Disconnect power
at service panel and have heater inspected by a qualified
electrician before reusing.
6. Do not use outdoors.
7. To disconnect heater, turn off power to heater circuit at main
disconnect panel.
8.Do not install less than 6 feet (1.8 m) high from the floor.
9.Do not insert or allow foreign objects to enter any ventilation or
exhaust opening as this may cause an electric shock or fire, or
damage the heater.
10.To prevent a possible fire, do not block air intakes or exhaust
in any manner.
11.A heater has hot and arcing or sparking parts inside. To reduce
the risk of fire, do not use it in areas where gasoline, paint, or
flammable vapors and liquids are used or stored.
12.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.
13. Do not install closer than 1 foot (0.3 m) from both sides and
rear of heater to any adjacent surface/wall.
High temperature, risk of fire, keep electrical
cords, drapery, furnishings, and other
combustibles at least 3 feet (0.9 m) from the
front of the heater and away from the side
and rear.

INSTALLING INSTRUCTIONS
All wiring must be installed by a certified electrician
according to the local electrical codes. The ceiling
heater must be grounded in accordance with all
national and local building codes.
High temperature, risk of fire, keep electrical
cords, drapery, furnishings, and other
combustibles at least 3 feet (0.9 m) from the front
of the heater and away from the side and rear.
To reduce the risk of fire, do not store or use
gasoline or other flammable vapors and
liquids in the vicinity of the heater.
All wiring procedures and connections shall be in accordance
with the national and local codes having jurisdiction.
Before installation:
Disconnect the main supply connection.
The heater must be connected to individual branch circuit.
Installation location:
1.Arrange units so their discharge air streams are subjected to a
minimum of interference from columns and partitions.
2.Direct air stream away from room occupants.
3.Do not blow air steam directly at wall.
4.Direct air stream along the windward side of a room when
installed in a building exposed to a prevailing wind.
5.If using a remote thermostat, locate thermostat approximately 5
feet above partition walls or posts away from cold drafts, internal
heat sources, and away from heater discharge air streams.
6.Large rooms require multi-unit installations. Arrange units to
provide perimeter air circulation where each unit supports the air
stream from another.
Mount the heater at least 6 feet above the floor
to prevent accidental contact with the fan blade
which could cause injury.
To prevent possible over heating or damage due
to overheating, keep at least a 5 feet clearance
in front of the heater. Refer to Table 1 for side,
top and back clearance requirements.

BRANCH CIRCUIT (POWER)
1. Connect heater only to the voltage, amperage and
frequency specified on the nameplate.
2. Field wiring must be properly sized to carry the amperage
in accordance with the NEC.
3. The access door is hinged. There are either one or two
screws accessible from the bottom that must be removed
to gain access.
4. A knockout is provided in the back of the heater close to
the power terminal board. The control terminal board
knockout is 1/2 inch conduit size. The power terminal
block knockout is multiple diameter. Use the diameter that
fits the required conduit size.
5. A ground terminal is provided near the power terminal
board. The ground wire should be connected before other
connections are made. The ground wire of model as
below.

Vertical or Horizontal Downflow Unit Heater
7. Each heater has a wiring diagram affixed to the inside of
the access door. Consult this diagram before making any
field connections.
8. Electrical Accessories, either kits or factory-installed
options, are shown connected by a dashed line on the
heater wiring diagram.
9. Single or three-phase connections may be used with
heater models 246132 and 246133. These units are
factory wired for single phase operation. If these heaters
are for use with three-phase power, reconnect the wires
as indicated in the wiring diagram attached to the heater.
CONTROL WIRING OF OPTIONAL
EQUIPMENT
Line voltage is present on some of the
terminals on the control terminal board.
Always disconnect the power from the heater
before making any connections to the control
board to prevent hazards.
1. Use min. 600 volt, NEC Class 1 insulated wire for all control
circuit wiring.
2. Use a crimp-on type fork terminal on the wire ends that
attach to the control terminal board if more than one
connection is to be made under the terminal screw.
3. Control wiring must be rated minimum 18 AWG.
NOTE: Thermostat and control circuit wiring must be
suitable to handle the full load of the heater

11.For model 246132 and 246133, the heaters are wired for
240V from factory. When heater is to be connected to
208V supply, the transformer leads have to be inter
changed. Inter change transformer red and black primary
leads (see wiring diagram on heater door). The color lead
is the COMMON for the 40VA control transformer
provided with these heaters.
How to install Wall Thermostat. (246110 Not

TROUBLE SHOOTING
If the heater fails to operate, please follow these procedures:
This heater has thermal cut-off protection. If the thermal cut-off
protection trips, turn off the power and switch off the circuit
breaker.
The unit should reset automatically after 10-30 minutes. If the
thermal cut-off protection trips again, consult a certified/licensed
electrician to determine the reason for overheating.
Unit is not
heating.
Overheat protection has temporarily deactivated the
heater.
Turn the heater OFF. Switch off the circuit breaker.
Wait 10-30 minutes before turning back on.
Breaker/Fuse has been tripped. Check your electrical box to confirm the breaker has
not been blown. This may occur if the receptacle is
shared with other high consumption appliances.
The heater is
producing a
burning smell.
Check & ensure there are no combustible materials
within 3ft. (0.9 meters) surrounding the heater. Remove any combustible items from the vicinity of
the heater.
A small amount of oil fell on the heating coil during
the manufacturing process. It will quickly evaporate
and should not occur again.
Ensure room in which heater is situated is well
ventilated.
Ensure a minimum clearance of 1 foot (0.3 m) from
both sides and rear of heater to any adjacent
surface/wall.
Reposition the heater so there is enough space
between the heater and any adjacent surface/wall.
Problem Probable Cause Solution
PLEASE DO NOT ATTEMPT TO OPEN OR REPAIR THE HEATER YOURSELF.
DOING SO COULD CAUSE DAMAGE TO THE HEATER OR PERSONAL INJURY.
