SPECIFICATIONS

General Safety Information

WARNING Read and understand installation and operation instructions and observe all safety instructions.

1. Use copper wire only for supply connections use 10 AWG or larger wires suitable for at least 167°F (75°C).
2. Heater air flow must be directed parallel to, or away from adjacent wall.
3. Observe wall, floor, and ceiling clearance requirements.
4. All wiring must conform to national and local electrical codes in the United States and the heater must be grounded as a precaution against possible electrical shock. Heater circuit must be protected with proper fuses.
5. The Mounting structure and the anchoring hardware must be capable of reliably supporting the weight of the heater and, if used, the mounting bracket.
6. All electrical power must be disconnected and the main service box must be locked before inspection, cleaning or servicing the heater. This is a precaution to prevent serious shock.
7. This heater is not suitable for use in hazardous locations as defined by the national fire protection association (NFPA) in the United States. This heater has hot and arcing (sparking) parts inside. Do not use in areas where gasoline, paint, or flammable liquids are used or stored.
8. This heater is not suitable for use in corrosive atmosphere such as marine, greenhouses or chemical storage areas.
9. Do not install closer than 8 inches to a vertical surface.
   Do not install less than 6 feet from the floor.

WARNING: Improper installation or failure to follow the procedures outlined in this instruction manual can result in serious electrical shock.

LOCATING HEATER

Install heater out of traffic areas maintaining clearances stated in figure 2. The direction of air flow should not be restricted (ie: by columns or machinery) and the air flow should wipe exposed walls, rather than blowing directly at them. When more than one heater is used in an area, the heaters should be arranged so that the air discharge of each heater supports the air flow of the others to provide best circulation of warm air, as indicated in Figure 3.

Installation

MOUNTING THE BRACKET

Refer to Figure 4a and 4b.
1. Locate a stud in the ceiling joist.
2. Remove the mounting bracket from the heating unit by loosening bracket thumb screws.
3. Drill a ¼” pilot hole in ceiling joints. Place a washer on screws before inserting through the holes in the mounting bracket, and screw them securely into a ceiling joist.
NOTE: If you want to swivel the heater either to the right or left, adding a washer to both sides of the bracket is recommended.
A longer Lag bolt may be required to properly secure the unit (see 4a).
4. Tighten screws enough to securely hold heating unit with air flow pointed in proper direction.

HANGING THE HEATER

1. Attach the heating unit to the mounting bracket.
2. Lift the heater up and into the mounting bracket.
3. Align the bracket screws with the keyholes slots in the mounting bracket.
4. If the heater is to be tilted, It must be positioned in the keyholes slots (see Figure 5)
5. Tighten the bracket screws with a wrench so the unit is securely suspended horizontal or vertical level.

CONNECTING THE POWER

1. Remove the screw from the front of the unit to connect the power to the heater.

2. Attach the cable connectors to the unit (See Figure 6) and slide the 10 gauge wire through the cable connector.
   NOTE:

   • This appliance must be grounded.
   • Proper size fuses and circuit breakers in accordance with the National Electric Code must be used.
   • The appliance must connect to a current protection circuit or device at 32-40 Amp before connecting to power supply.
   • For certain applications, conduit may be required (See Figure 6). Check local electrical codes. If you run the wiring in conduit and wish to be able to turn the heater be sure to purchase enough flexible conduit to allow the heater to be turned.

3. Pull enough properly sized wire through cable connector and connect the wire to the power block located in the base of the heater (see Figure 7).

4. Turn on the power at the main service.

Operation

SETTING THE THERMOSTAT

1. Rotate thermostat knob clockwise to high position.
2. After room reaches desired comfort level, rotate thermostat knob counter-clockwise until the thermostat clicks off.

NOTE: Heater will cycle on and off to maintain room temperature. The first time you operate the unit, it may smoke slightly. This is due to residual cleaning agents used to clean the element when the heater is manufactured. This is normal and does not indicate a problem with the unit. This condition will stop after the heater has been in operation for a few minutes.

THERMAL CUTOUT

The heater is equipped with a thermal cutout which will automatically shut off the heater in the event of overheating.
The heater will turn on when the abnormal temperature returns to normal. Should the unit overheat and cause the thermal cutout to cycle, the cause of the overheating should be determined and corrective action taken before further operation.

ADJUSTING AIR FLOW DIRECTION

1. Turning the unit – If the unit has been installed with a single lag bolt, as shown in the Figure 4a, simply turn the entire unit as needed to adjust air flow (see Figure 8).

2. Tilting the unit – Loosen the bracket screws (see Figure 5).
   NOTE: To tilt the heater it must be mounted in bottom keyhole slots of mounting brackets to maintain adequate clearance and prevent possible overheating.

3. Adjusting the louvers to the desired position.
   NOTE: The louvers are designed so they can’t be completely closed. Do not attempt to defeat this feature, damage to the unit can result.

SAFETY INSTRUCTIONS

• This heater is hot when in use. To avoid burns, do not let bare skin touch hot surfaces. If provided, use handles when moving this heater. Keep combustible materials, such as furniture, pillows, bedding, papers, clothes, and curtains at least 3 feet (0.9 m) from the front of the heater and keep them away from the sides and rear.
• This heater is not intended for use in bathrooms, laundry areas and similar indoor locations. Never locate heater where it may fall into a bathtub or other water container.
• This heater is designed to be directly wired to 240 volt electric power. Never use with an extension cord or relocatable power tap (outlet/power strip).

CLEANING THE HEATING ELEMENT

WARNING: To Prevent possible electric shock, all power must be shut off at the main service before inspecting or cleaning.
To clean the heating element, loosen (but do not remove) the four Phillips head screws located behind the louvers in the corners of the louver housing on both sides, lift up, and pull out (see Figure 10). This provides access to the heating element. Remove dust or lint with a soft brush or a vacuum cleaner. Replace the louver housing and tighten the Phillips head screws.

WARNING: Use care to prevent damage to internal heater wiring when cleaning element. make sure all connections remain tight and all wiring is routed away from element fins when reassembling the unit. Allowing wiring to touch the element fins could result in a fire hazard.

CLEANING THE FAN AND MOTOR

WARNING: To prevent possible electric shock, all power must be shut off at the main service before inspecting or cleaning.

Remove the protective grill from the rear of the heater. This provides access to the fan and motor. Wipe off the fan and the motor with a soft cloth or brush. The fan motor does not require lubrication. Replace protective grille (see Figure 11).
