INSTALLATION & MAINTENANCE MANUAL

WARNING

Model: KBP2406 is 240 volt. It is important that you

verify the 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 will operate at 208 volt but will produce

25% less wattage and draw 13% less Amps. 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

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

with 3/8" x 1" wingnut & lock washer supplied. Install the lock washer

between the bracket and heater. Do not put lock washer on the plastic

wingnut. After desired air discharge position has been determined

tighten wingnut so heater will not pivot.

Location of Heater

The heater should be installed out-of-reach of persons. 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

should be arranged so that the air discharge of each heater supports

the airflow of the others to provide best circulation of warm air. (see

airflow chart)

1. Remove wiring compartment cover.

2. Remove one of the knockouts from back of unit.

It is not necessary to remove grill covers.

3. Size service wire to adequately handle Amp load

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.

WARNING - Before proceeding further

with the installation of this heater, turn off

the power and lock the supply line for the

heater at the main service box.

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 20 Amp heating circuit can not have more than 16 Amps of load connected. If heater is

operated at 208V it will draw 13% less Amps 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.
