INSTALLATION & MAINTENANCE MANUAL
Model: KBP2406 240V-1phase Unit Heater
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. 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
Unpack & Inspect Your New Heater
Remove heater from box and inspect it for any damage. Verify
you have received the mounting bracket and accessories.
codes. Heater circuit must be properly protected.
Mounting Heater
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).
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)

* 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.
