INSTALLATION INSTRUCTIONS

HEATER LOCATION:

Install heater out of traffic areas maintaining clearances stated in Figure 1. The direction of air flow should not be restricted (i.e.: 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 2.

MOUNTING THE BRACKET:
Refer to Figure 3a and 3b.

• Locate a stud in the ceiling joist.
• Remove the mounting bracket from the heating unit by loosening bracket thumb screws.
• Drill a 1/4″ 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 3a).
• Tighten screws enough to securely hold heating unit with air flow pointed in proper direction.
  

HANGING THE HEATER:

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

CONNECTING THE POWER:

• 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 5) and slide the 8-guage wire through the cable connector.
• NOTE: This appliance must be grounded.
• NOTE: Proper size fuses and circuit breakers in accordance with the National Electric Code must be used.
• NOTE: The appliance must connect to a current protection circuit or device at 50A or more before connecting to power supply. Higher protection limits may be required by code. Check your local electrical codes.
• NOTE: For certain applications, conduit may be required (See Figure 5). 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.

CONNECTING THE POWER (continued):

• 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 6).
