e 75% making the
heater feel barely warm. Connecting a 120 Volt heater to a 240 Volt circuit will
destroy the heater, voids all warranties and could cause re damage.
WARNING: Turn off power source to the heater before attempting installa-
tion, maintenance or repairs. Lock, tape or tag circuit breaker or fuse so that
power cannot be turned on by accident. Failure to do so could result in serious
electrical shock, personal injury, property damage or death.
PLACEMENT: When possible baseboard heaters should be placed on an
outside perimeter wall under a window. This is due to the fact that the out-
side wall is usually the spot of greatest heat loss. A baseboard heater may
sit directly on any oor surface including carpet. Do not allow carpet to block
air intake at bottom.
GENERAL SAFETY INFORMATION: Keep electrical cords, any bulky fur-
niture or other household items that could restrict air ow away from heater.
Refer to clearance diagram for drapes. Do not install heater below an electri-
cal outlet or against vinyl wallpaper, paperboard or low density berboard
surfaces. Do not recess mount heater. Do not mount heater vertically. Do not
store ammable liquids in vicinity of the heater. Installation must comply with
applicable national and local electrical codes. Protect electrical supply wire
from nicks, sharp objects, oil, grease or other chemicals that could damage
the insulation.
INSTALLATION INSTRUCTIONS:
1. Make sure heater is positioned on the wall with the Bottom label facing
the
oor. Mounting the heater upside down could be a hazard.
2. Remove junction box cover from left or right end. The heater can be
wired from either end.
3. Remove knockout and pull supply wires through. Use a cable tting to
secure the power wires.
4. Locate wall studs and secure heater to wall with a nail or screw. Use the
mounting dimples in the back can to position the fastener. The dimples
will prevent the fastener from slipping when applying pressure to pierce
the metal back can. The cover or re ector to do not need to be removed
to mount the heater.
5. Connect electrical wires and groundwire to the heater per the appropri
ate wiring diagram on following pages.

2007 K series.indd : 6/07 COMMONLY ASKED QUESTIONS
Q. Will the room heat up faster with the thermostat turned up to 90
degrees?
A. No. The heater is always on full wattage when the thermostat is
below the pre-set temperature. The thermostat shuts off when the
pre-set temperature is reached so set the thermostat to the desired
comfort level, not above.
Q. Will the electricity bill be lower using 240 Volt heaters?
A. No. Electricity is billed by kilowatt hours - voltage makes no dif-
ference. Typically, baseboard heaters are 240V because of wiring
capacity, i.e. 240V heaters draw less Amps than 120V heaters.
Q. What is the difference between a two pole and a single pole
thermostat?
A. A 1-P thermostat has no positive off position. That means when
the knob is turned all the way to the left (counterclockwise) it has a
Maintenance: The high quality and superior design of this heater will provide years of trouble-free performance. Each year the heater should
be checked and cleaned for lint and dust accumulation. King recommends using a soft bristle brush to knock off contaminates, then vacuum
out remaining debris.
Warranty: King Electrical Mfg. Co. will repair or replace, without charge to the original owner, any baseboard heater found to be defective or
malfunctioning for 12 months from the date of purchase. If the product becomes defective within the warranty period contact King at 800-603-
5464 for instructions on how to repair or replace heater. Do not return the heater to the store. All returned goods require a Returned Goods
Authorization (RGA). Products returned without proper authorization will be refused.
low setting. A 2-P thermostat breaks an additional line when the knob
is turned to the off position. The heater will not turn on with the knob
in the off position.
Q. Can the baseboard heater be painted?
A. It is not recommended. The factory paint is a special high tem-
perature paint. A standard home wall paint will burn off and discolor.
A high temperature stove paint will work, but be careful to not get any
paint on the element or limit.
Q. How much heat do I need?
A. A general rule of thumb is 10 Watts for every square foot of oor
space. For example: A 10' x 10' room is 100 ft² (10 w/ft² x 100 ft²)
and would require 1000 Watts of heat. If you live in a cold climate or
if the room has a ceiling height above 8ft. use up to 15 w/ft².

1. Find source of short. Trace heater circuit and verify the heater is wired
properly.
2. Reduce wattage in circuit. Refer to circuit sizing table for maximum
wattage.
3. Verify the heater voltage matches the supply voltage.
1. Turn breaker on. Turn thermostat on. Check that the breaker is positioned
properly on panel bus-bar. A 2-Pole breaker must be connected
to both bus-bars (A & B phase) to produce 240V power.
2. Tighten wire connections.
3. By-pass the limit to test. If heater works, replace the limit.
1. It is normal for the element to burn off some light nishing oil used in
the manufacturing process when rst energized. Open windows and
allow room to vent until it stops, usually within a few minutes.
2. Remove any dust or dirt accumulation.
1. Sunlight or other heat sources can affect the thermostat. Move the
