DESCRIPTION

The heavy-duty electric heater is designed for garages, workshops, and similar locations. It features two heat settings, for maximum heat production of 25,589BTU per hour. It includes horizontal and vertical airflow and a built-in thermostat with overheating safety thermal cutout.

SPECIFICATIONS

GENERAL SAFETY INFORMATION:

WARNING: This heater requires to hardwire installation (no plug). The installation of this product must be carried out by a  certified electrician and in accordance with all local and national electrical codes.
NOTE: Compatible with a 240V line voltage single pole wall thermostat (not included). This heater must be installed by a  certified electrician.

1. Use only copper wires rated for at least 75ºC.
2. Heater airflow must be directed parallel to or away from the adjacent wall.
3. Observe wall, floor, and ceiling clearance requirements.
4. All wiring must be done according to national and local electrical codes in the United States. The heater must be grounded as a precaution against possible electrical shock. The heater circuit must be protected with proper fuses.
5. The mounting structure and the anchoring hardware must be capable of supporting the weight of the heater and the mounting bracket (if used).
6. All electrical power must be disconnected and the main service box, which must be locked before connecting, inspecting,  cleaning, or servicing the heater. This is a precaution to prevent serious electric shock.
7. This heater is not suitable for use in hazardous locations as defined by the national fire protection association (NFPA) in Canada. This heater has hot and arcing sparking parts inside. Do not use it in areas where gasoline paint or flammable liquids are used or stored.

9. The heater must be mounted at least 8 feet above the floor.

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

LOCATING THE HEATER

Install heater out of traffic areas, maintaining clearances stated in figure

1. The direction of airflow should not be restricted by columns or machinery and the airflow should wipe exposed walls rather than blowing directly on them. When more than one heater is used in an area, the heaters should be installed so that the air discharge of each heater supports the airflow of the others, to provide the best circulation of warm air as indicated in figure 2.

INSTALLATION

Hardware needed
You will also need the following hardware, which can be purchased from your local a hardware store or electrical supply store:

• Electric wire in the adequate gauge and length for your application;
• Proper size fuse or breaker for your heater’s amperage;
• Proper wire connectors for your application;
• Fasteners appropriate for your application that are strong enough to hold the unit.

Mounting the bracket

Refer to Figures 3a and 3b.

1. Locate a wood stud in the wood ceiling joist. If you cannot locate a wood stud, you have to install a wood piece on the ceiling as this heater must be securely fastened.
2. Remove the mounting bracket from the heating unit by loosening bracket screws with a wrench and slipping the handle off over the screw heads.
3. 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 Figure 3a.

HANGING THE HEATER

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

Figure 4

ADJUSTING AIRFLOWDIRECTION

1. To turn the unit horizontally when it has been installed with a single lag bolt (as shown in figure 3a), simply turn the entire heater as needed. (as shown in figure 5 – rotate). The unit cannot be turned horizontally if it has been installed with 2 lag bolts.
2. To tilt the unit vertically, loosen the bracket screws (see figure 4) and see figure 6 to view multiple vertical angles.
3.  Adjust louvers to the desired position.

NOTE: The louvers are designed so they cannot be completely closed. Do not attempt to defeat this feature; damage to the unit can result.
NOTE: To prevent possible overheating, please maintain adequate clearance as shown in figure.1.

OPERATING INSTRUCTIONS

Figure 11

WARNING: The heater must be properly installed before it is used.

SETTING THE THERMOSTAT

1. Rotate the thermostat knob clockwise to a high position, the amber POWER INDICATOR light will turn on.
2. After the room reaches desired comfort level, rotate the thermostat knob counterclockwise until a click is heard, then rotate it slightly higher (toward Max).
   NOTE: The heater will cycle on and off to maintain room temperature.

POWER SELECTION SWITCH
Using the POWER SELECTION SWITCH, select the heating output: I for 6250W, II for 7500W.

THERMAL CUT-OUT
The heater will automatically turn off should it overheat. When this happens, the red indicator will turn on. After the unit has cooled back down to a normal level, the heater will turn ON again and the red indicator will turn off, but the reason for the overheating must be determined and corrective action must be taken before further operation.

THE HEATER MUST BE TURNED OFF IMMEDIATELY WHEN THE CAUTION INDICATOR IS GLOWING RED.

NOTE: When the thermal cut-out is activated, the caution indicator will turn red. In this case, immediately turn the heater OFF  and inspect for any objects on or adjacent to the heater that may cause high temperatures.

MAINTENANCE INSTRUCTIONS

1. Before cleaning, make sure the power has been turned off at the circuit breaker panel and the heating element of the heater is completely cool.
2. To maintain the heater’s appearance, it needs only to be wiped over occasionally with a dry duster. During the summer months, or at other times when the appliance is not in use and is completely cold, wipe over with a damp cloth. Never allow water to drip into the heater.
3. Do not use abrasive cleaning powders or furniture polish. Do not use chemical or abrasive products, metallic scourers, and so on, which may deteriorate the surface, to clean the appliance.
4. During the summer months, or at other times when the appliance will not be used for extended periods of time, disconnect the power supply and cover the whole appliance with a dust cloth. Store the heater in a dry and cool place.
5. All other servicing should be performed by qualified service personnel. Do not try to repair the heater yourself.
