• A heater has hot and arching or sparking parts inside. Do not use by or near children or invalids and whenever the heater is left operating and unattended.
• Do not operate any heater after it malfunctions. Disconnect power at the service panel and have the heater inspected by a qualified electrician for repair before reusing.
• Do not use outdoors. use it in areas where gasoline, paint, or flammable vapors or liquids are used or stored.
• Use this heater only as described in this manual. Any other use is not recommended by the manufacturer and may cause fire, electric shock, explosion or injury to people and or property.

SELECTING HEATER LOCATION

DO NOT install less than 6″ (15cm) from vertical side walls or open edge of door. This heater must have unrestricted airflow. DO NOT select a location where it is likely to be blocked by furniture, curtains, etc. Be sure the location selected allows sufficient space for the heater DO NOT locate this heater in an area where combustible vapors, gases liquids, or excessive lint, dust or moisture is present

INSTALLATION

The wire and breaker sizing chart will give a general rule of installation size. Consult an electrician if you are not knowledgeable about wiring codes

Total Amps

| Minimum AWG. Wire Size (Copper| Circuit Breaker or Fuse Size
---|---|---
0 thru 12| #14| 15 amp
12.1 thru 16| #12| 20 amp
16.1 thru 24| #10| 30 amp

INSTALLATION STEPS

• Connect the heater only to the voltage, amperage, and frequency specified on the nameplate.
• Wiring procedures and connections shall be in accordance with all National and local codes having jurisdiction.
• Sst the bag containing the grill and packet with two (2) grill screws aside.
• Loosen mounting screw and remove fan heater assembly.
• A knockout of 1/2 inch conduit size (7/8 inch/ 2.2cm) is pro
• Install a wall box a minimum of 6″ from vertical sidewalls and 4″ above the floor.
• The front edge of the wall can extend 1/2″ beyond the finished wall surface.
• Secure wall box to the 2 x 4 studs using the two (2) holes on the side of the wall box. Secure to a wall stud on the opposite side if required.
• Connect supply wires, and attach ground feed wire to the green ground wire with wire nuts.
• Reinstall the heater assembly into wall box with a screw at top of the interior.
• Install the grill securely with the screws provided in the packet. Do not over-tighten.
• Test the unit by turning the thermostat up past room temperature. You will see a puff of smoke as the elements are energized and the fan turns on.
• This is a normal burn-off of manufacturing lubricants and will dissipate in 5 minutes.
• Heater will continue to run until the room temperature you set is reached and then turn itself off until the temperature drops again.

OPERATING INSTRUCTIONS

This heater is equipped with a thermal overload Smart Limit Protection which disconnects elements and motor in the event normal operating temperatures are exceeded. If thermal overload PROTECTION trips due to abnormal operating temperatures, thermal overload shall remain open until manually reset by turning the heater OFF for fifteen minutes. Inspect for any objects on or adjacent to the heater that may cause high temperatures. After inspecting the heater, keep the power to the heater off for 10 minutes to reset the SLP thermal protector. If the SLP thermal protector shuts the heater off again, immediately turn the heater OFF at the circuit breaker and inspect the heater for possible fan motor failure or dirt and lint on the heating element. Repeat the starting procedure.

General information and Guidelines:
This heater must be properly installed before it is used. DO NOT tamper with or change the operating of this heater. All services should be performed by a authorized service representative. Only replace components with King-approved replacement parts

• This heater must be properly installed in accordance with the National Electrical Codes (NEC) & local electrical codes before it is used.
• After the electric heater has been completely installed, all thermostats should be turned to LOW or NO HEAT.
• Turn ON breakers, wait 3 to 5 minutes and check to see that the heaters are not operating.
• If operating, disconnect power and check for improper wiring. If none are operating then turn thermostats to highest position and wait 3 to 5 minutes.
• Check to see that all heaters are operating. Should any not be operating, disconnect power and check wiring.
• Allow entire system to operate steadily for 1 /2 hour. This should remove oily residue from manufacturing. (Some smoking may occur).
• Select the setting for comfort on all thermostats.
• A safety limit control is provided to turn off the heater automatically if it is blocked or otherwise overheats due to an abnormal condition.
• DO NOT bypass or remove this safety device from the electrical circuit-see Warning Figure 4 on page 2.
• During normal use, this safety control should not operate.
• If you find that this control is operating, make sure the heater is not being blocked.
• If it continues to cycle the heater off, disconnect power to heater and have it checked and repaired by a qualified electrician

Maintenance & Cleaning

Basic maintenance is listed below and should be performed annually. When necessary, any required servicing should be performed by qualified service personnel. Your heater will give you years of service and comfort with only minimum care. To assure efficient operation follow the simple instructions below.

• Before removing the grill, turn the electrical power OFF and the elements to cool.
• Circuit breakers are often not marked correctly and turning the wrong breaker off could mean electricity is flowing to the heater, even if the heater does not appear to be working.
• If you are uncomfortable working with electrical appliances, unable to follow these guidelines, or do not have the necessary equipment, consult a qualified electrician.
• Once you verify the power is off completely and element is cool, proceed to the next step.
