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.

4. Always switch off the heater when not in use.

5. Do not operate any heater after the heater malfunctions, has 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.

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.

User’s Manual

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.

6. The power terminal board is equipped with box terminals sized to accept the correct size power supply wire. Wire rated at 600V and 194°F is satisfactory for the heater branch circuit. Copper wire is satisfactory for connection to the heater power terminal board box terminal.

User’s Manual

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

Ground Wire

10. Connect the red live wire to L1, black live wire to L2 and white live wire to L3 of the connector. Connect ground wire to .

L1: red live wire L2: black live wire L3: white live wire

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 Included.)

1.Install Thermostat Outlet Box to the wall. Open the knock-out on the right. Run line voltage wires to the thermostat location via the knock-out.

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 T

O THE HEATER OR PERSONAL INJURY.
