LOCATING HEATER
Install heater out of traffic areas, maintaining clearances stated in Figure 1. The direction of airflow should not be restricted is by columns or machinery and the airflow should avoid exposed walls rather than blowing directly on 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 airflow of the others to provide the best circulation of warm air as indicated in Figure 2.

INSTALLATION INSTRUCTIONS
HARDWARE NEEDEDYou will need the following hardware, which can be purchased from your local hardware store or electrical supply house:
- Adequate gauge and length of wire for your application.
- Proper size fuse or breaker to handle the amperage.
- Proper wire connectors for your application.
- Fasteners are appropriate for an application that are strong enough to hold the unit.
MOUNTING THE HEATER ON THE CEILING
- 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.
- Remove the mounting bracket from the heating unit by loosening bracket screws with a wrench and slipping the handle off over the screw heads.
- 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
- Lift the heater up and into the mounting bracket.
- Align the bracket screws with the keyhole slots in the mounting bracket.
- If the heater is to be tilted it must be positioned in the keyhole slots — see Figure 4.
- Tighten the bracket screws with a wrench so the unit is securely suspended at a horizontal or vertical level.
ADJUSTING AIRFLOW DIRECTION
- To turn the unit when it has been installed with a single lag bolt (as shown in Figure 3a), simply turn the entire heater as needed. The unit cannot be turned horizontally if it has been installed with 2 lag bolts.
- To tilt the unit vertically, loosen the bracket screws (see Figure 4).
- Adjust louvers to the desired position.NOTE: To prevent possible overheating, please maintain adequate clearance as shown in Figure 5.
NOTE: The louvers are designed so they cannot be completely closed. Do not attempt to defeat this feature; damage to the unit can result.
MULTIPLE VERTICAL ANGLES
WARNING:To prevent possible electric shock, disconnect power to the heater at the main service box before attempting to adjust the heat output of this unit.CONNECTING THE POWER

TO PROTECT THE HEATING ELEMENTThe heater includes a fan delay function to prevent the risk of overheating. When turning the heater off, the unit will close the heating element first and then the fan will continue working for 60 seconds to dissipate residual heat.
- Remove the screw from the front of the unit to connect the power to the heater.
- Attach the cable connectors to the unit (see Figure 8) and slide the 8-gauge wire through the cable connector.
NOTE: All wiring must be carried out by a certified electrician and must be in accordance with applicable national and local electrical codes. For certain applications, the conduit may be required. 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 conduits to allow the heater to be turned. - Connect the wire to the power block located at the base of the heater. (Figure 9)
- Turn on the power at the main electrical panel.
