INSTALLATION & MAINTENANCE MANUAL
WARNING
Model: KBP2406 is 240 volt. It is important that you
verify the power supply voltage is the same as the
nameplatevoltageofthe heater. Improperinstallation
or failure to follow the procedures as outlined in this
manualcanresult in damagetothe heater. Note that
theKBP2406will operate at 208 voltbutwillproduce
25%less wattage anddraw13% lessAmps. Discon-
nect all power from the heater at the main service
panel before attempting to install or service this unit.
All electrical wiring must conform to local electrical
codes. Heater circuit must be properly protected.
Unpack & Inspect Your New Heater
Remove heater from box and inspect it for any damage. Verify
you have received the mounting bracket and accessories.
Tools Needed
You will need the following tools to install your unit heater:
-Screwdriver - (Phillips & Slotted)
-Wire Cutters
-Pliers
-Adjustable Wrench
-Electric Drill
Hardware Needed
Y ou will need the following hardware:
-Adequate gauge & length of wire for your application
-Proper size fuses or breakers to handle amperage
-Proper wire connectors for your application
-Appropriate size fasteners to mount heater.
In certain applications conduit may be required by code.
Check local electrical codes. If you want to be able to turn the
heater be sure to use flexible conduit.
Mounting Height
When the air flow of the heater is directed vertically or
horizontally the minimum mounting height is 6 feet in USA
and 8 feet in Canada. Mounting heights depend upon building
utilization and heater kW capacity.
Distance From Walls
Maintain 6" minimum clearance to side walls and 2" to ceiling
in back of the heater (air intake side). Maintain 18" clearance in
front of the heater (discharge side).
Mounting Heater
Locate a stud in ceiling or wall and securely fasten bracket with a
minimum of two #12 fasteners 1-1/4" long. Attach heater to bracket
with3/8"x1" wingnut& lockwasher supplied.Install thelock washer
betweenthebracket andheater. Donotput lockwasheron theplastic
wingnut. After desired air discharge position has been determined
tighten wingnut so heater will not pivot.
Location of Heater
Theheater shouldbeinstalled out-of-reachofpersons. The direction
of airflow should not be restricted by machinery, beams, etc. and
the airflow should wipe exposed walls, rather than blowing directly
at them. When more than one heater is used in an area the heaters
shouldbe arrangedso thatthe airdischarge ofeach heatersupports
the airflow of the others to provide best circulation of warm air. (see
airflow chart)

of heater. Refer to the Circuit Sizing Table for
proper wire size and circuit protection.
4. Connect supply wire to L1 & L2 as shown in the
diagram below.
5. Secure power supply cable with clamps.
6. Connect groundwire to the green pigtail.
7. Reinstall wiring compartment cover.
8. Adjust the heater to the desired position.

INSTALLATION INSTRUCTIONS
This heater is shipped from the factory wired for
maximum wattage of 5700 Watts at 240 Volts.
To reduce the wattage unplug (disconnect) an
insulated push on terminal and wrap with electrical
tape to prevent the possibility of electrical contact
with other parts.

Maintenance & Warranty Information:
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. We recommend using a soft bristle-
brush such as a paint brush to assist in removing contaminants from the heater. The motor is permanently lu-
bricated and does not need servicing. King Mfg. Company will repair or replace without charge any KBP2406
heater found to be defective or malfunctioning for five years after purchase to the original owner.

CIRCUIT SIZING TABLE
* Per the National Electric Code heating circuits are considered a continuous load and therefore must be derated
by 20%. For example: a 20Amp heating circuit can not have more than 16Amps of load connected. If heater is
operated at 208V it will draw 13% lessAmps and produce 25% less wattage.
**Assumes an 8 ft. high ceiling; Use cubic feet to estimate wattage requirement when ceiling is not 8 ft.
*** If area is larger than 720 sq. ft. / 5,760 cubic feet use more than one heater.

INSTALLATION & MAINTENANCE MANUAL
WARNING
This KBP2406-3MP is 240 Volt and the KBP2006-3MP is 208
Volt. It is important you verify your power supply voltage is
the same as the nameplate voltage of the heater. Improper
installation or failure to follow the procedures as outlined in
this manual can result in damage to the heater. Note that the
KBP2406-3MP will operate at 208 Volt but will produce 25%
less wattage and draw 13% less Amps. Both these models
can be field-wired for 1-Phase or 3-Phase (refer to the wir-
ing diagram on back page). Disconnect all power from the
heater at the main service panel before attempting to install
or service this unit. All electrical wiring must conform to local
electrical codes. Heater circuit must be properly protected.

Mounting Heater
Locate a stud in ceiling or wall and securely fasten bracket with
a minimum of two #12 fasteners 1-1/4" long. Attach heater to
bracket with 3/8" x 1" wing nut & lock washer supplied. Install
the lock washer between the bracket and heater, do not put
lock washer on the plastic wing nut. After desired air discharge
position has been determined, tighten wing nut so that heater
will not pivot.
Location of Heater
The heater should be installed out of the reach of persons.
The direction of air flow should not be restricted by machinery,
beams, etc., 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. (See Air Flow Chart)
