4. FUELS
For optimal performance of this heater, it is strongly suggested that 1-K kerosene be used. 1-K kerosene has
been refined to virtually eliminate contaminants, such as sulpher. Which can cause a rotten egg odor during
is not available. Be advised that these fuels do not burn as clean as 1-K kerosene, and care should be taken to
KEROSENE SHOULD ONLY BE STORED IN A BLUE CONTAINER THAT IS CLEARLY
MARKED “KEROSENE”. NEVER STORE KEROSENE IN A RED CONTAINER.
Red containers are associated with gasoline.
NEVER store kerosene in the living space. Kerosene should be stored in a well ventilated place outside the
living area.
NEVER
NEVER use fuel such as gasoline, benzene, alcohol, white gas, camp stove fuel, paint thinners, or other oil
compounds in this heater. These are volatile fuels that can cause an explosion or uncontrolled flames.
NEVER store kerosene in direct sunlight or near a source of heat.
NEVER use kerosene that has been stored from one season to the next. Kerosene deteriorates over time.
“OLD KEROSENE” WILL NOT BUR N PROPERLY IN THIS HEATER.
the operation of the heater. However, #1/#2 diesel/fuel oil, JET A or JP-8 fuels may also be used if 1-K kerosene
provide more fresh air ventilation to accomodate any added contaminants that may be added to the heated space.
#2 diesel/fuel oil heavier than 1-K kerosene in extreme cold temperatures without nontoxic anti-icer additives
will not ignite properly.
use any fuel other than 1-K kerosene (#1/#2 diesel/fuel oil, JET A or JP-8 fuels are acceptable substitutes)

5. OVERVIEW OF HEATERS DESIGN
Fuel System : This heater is equipped with an electric
air pump that forces air through the air
line connected to the fuel intake and then
through a nozzle in the burner head.
When the air passes in front of the fuel
intake it causes fuel to rise from the tank
and into the burner nozzle. This fuel and
air mixture is then sprayed into the
combustion chamber in a fine mist.
“Sure Fire Ignition” : The electronic ignitor sends voltage to a specially designed spark plug.
The spark plug ignites the fuel and air mixture described above.
The Air System : The heavy duty motor turns a fan that forces air into and around the combustion chamber.
Here the air is heated and then forced out the front of the heater.
The Safety System :
A. Temperature Limit Control : This heater is equipped with a Temperature Limit Control designed to turn
off the heater should the internal temperature rise to an unsafe level. If this
device activates and turns your heater off it may require service.
Once the temperature falls below the reset temperature you will be able to start your heater.
B. Electrical System Protection : This heaters electrical system is protected by a fuse mounted to the PCB
assembly that protects it and other electrical components from damage.
If your heater fails to operate check this fuse first and replace as needed.
C. Flame-Out Sensor : Utilizes a photocell to monitor the flame in burn chamber during normal operation.
It will cause the heater to shut-off should the burner flame extinguish.

6. FUELING YOUR HEATER
NEVER FILL THE HEATER FUEL TANKIN THE LIVING SPACE: FILL THE TANK OUTDOORS.
DO NOT OVERFILL YOUR HEATER AND BE SURE HEATER IS LEVELED.
IMPORTANTNOTICEREGARDING FIRSTIGNITION OF HEATER :
The first time you light the heater, it should be done outdoors. This allows the oils, etc. used in
manufacturing the heater to burn off outside.
WARNING!! : NEVER REFILL HEATER FUEL TANKWHEN HEATER IS OPERATINGOR STILL HOT.
7. OPERATION
A.) VENTILATION
RISK OF INDOOR AIR POLLUTION/USE HEATER ONLY IN WELL VENTILATED AREAS.
Provide a fresh air opening of at least three square feet (2,800 sq. cm) for each 100,000 BTU/Hr.
rating. Provide extra fresh air if more heaters are being used.
Example : A KFA220C heater requires one of the following:
• a two-car garage door raised six inches (15.24 cm)
• a single-car garage door raised nine inches (22.86 cm)
• two, thirty-inch (76.20 cm) windows raised fifteen inches (38.1 cm)
B.) OPERATION
TO START HEATER
1. Fill fuel tank with fuel.
NOTE : Kerosene is recommended when the temperature drops below 0℉(-18℃) to prevent ignition
delay or failure.
2. Attach fuel cap.
3. Plug power cord of heater into three-prong, grounded extension cord. Extension cord must be at
least six feet long.
Extension Cord Wire Size Requirements
• 6 to 100 feet (1.8 to 30.5 meters) long, use 16 AWG conductor.
• 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.
4. Turn “THERMOSTAT CONTROL knob” to desired setting (setting range : 40˚F ~ 110˚F)
5. Push “BTU control Switch” to “High” level.(See Figure 8.)
6. Push Power Switch to “ON” position, Power lndicator Lamp will light and heater will start.
7. After startup, push “BTU control switch” to desired level “High or Low”
NOTE : Room Temperature display explanations are as follows: (KFA135C/220C Models only)
•When the room temperature is less 0℉, the LED display will show “Lo”
When room temp is between 0℉ and 99℉, the number shown on the display is the current
room temperature.
When room temperature is greater than 99℉, the LED display will show “Hi”
•
•If heater does not start, the thermostat setting may be too low, turn “thermostat Control Knob” to
higher position to start heater. If heater still does not start, turn power switch to “OFF” and then to
“ON” position. If heater still does not start, see Troubleshootiong Guide on page15.
NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
NOTE : User can select to operate the heater on two different BTU levels(High or Low).
To stabilize heater and prevent ignition delay, select BTU level after turning the heater on, or
while it is in operation by pushing the BTU control switch. If the heater started at low BTU level
in cold weather or low fuel tank, ignition failure can occur.
NOTE : In cold weather, ignition may be improved by holding a finger over the end of the relief valve or
block fanguard in half with newspaper etc. until the heater ignites.

NOTICE : The major electrical components of this heater are protected by a safety fuse mounted to the PCBboard.
If your heater fails to start, check this fusefirst and replace as necessary. You should also check your
power source to insure that proper voltage and frequency are being supplied to the heater.
TO STOP HEATER
1. Turn switch to “OFF” and unplug power cord.
TO RESTART HEATER
1.Wait 10 seconds after stopping heater.
2. Repeat steps under to start heater.

WARNING : SHOCK HAZARD!
8. LONG TERM STORAGE OF YOUR HEATER
FUEL TANK DRAIN
1. Drain fuel tank through fuel cap opening.
(For KFA80C Model Only)
2. Remove fuel drain bolt from rear bottom side of fuel tank using 3/4” socket or adjustable wrench and drain.
(For KFA135C /220C Models Only. See Figure 10)
3. Using a small amount of kerosene, swirl and rinse the inside of the tank.
NEVER mix water with the kerosene as it will cause rust inside the tank.
Pour the kerosene out making sure that you remove it all.
IMPORTANT : Do not store kerosene over summer months for use during next heating season.
Using old fuel could damage heater.
4. Reinstall fuel cap. Properly dispose of old and dirty fuel.
(For KFA80C Models Only)
5. Reinstall fuel drain bolt to Fuel tank and tighten firmly using 3/4” socket
or adjustable wrench. (For KFA135C /220C Models Only. See Figure 10)
IMPORTANT : Before reinstalling the fuel drain bolt, make sure the
seal is on the bolt. If the seal is not used the bolt cannot
be installed correctly and the fuel tank will leak.
6. Store heater in dry well ventilated area. Make sure storage place is free
of dust and corrosive fumes.
7. Store the heater in the original box with the original packing material and keep the USER’SMANUAL
with the heater.
•Always cover electric outlet when not in use.
•Don’t plug and use a appliance more than 120V/60Hz 5A
current in this outlet.
