4. FUELS
For optimal performance of this heater, it is strongly suggested that 1-K kerosene be used. 1-K kerosene has
been rened to virtually eliminate contaminants, such as sulpher. Which can cause a rotten egg odor during
the operation of the heater. However, #1/#2 diesel/fuel oil, JET A or JP-8 fuels may also be used if 1-K
keroseneis not available. Be advised that these fuels do not burn as clean as 1-K kerosene, and care should
be taken to 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 non
toxic anti-icer additives will not ignite properly.
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 use any fuel other than 1-K kerosene (#1/#2 diesel/fuel oil, JET A or JP-8 fuels are acceptable substitutes)
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
ames.
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 BURN PROPERLY IN THIS HEATER.

5. OVERVIEW OF HEATER’S 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 ne 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.

B. Electrical System Protection : This heater’s 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 rst and replace as needed.
C. Flame-Out Sensor : Utilizes a photocell to monitor the ame in burn chamber during normal operation.
It will cause the heater to shut-off should the burner ame extinguish.

6. FUELING YOUR HEATER
NEVER FILL THE HEATER FUEL TANK IN THE LIVING SPACE : FILL THE TANK OUTDOORS.
DO NOT OVERFILL YOUR HEATER AND BE SURE HEATER IS LEVELED.
IMPORTANT NOTICE REGARDING FIRST IGNITION OF HEATER :
The rst 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 TANK WHEN HEATER IS OPERATING OR 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 KFA220H 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 fteen inches (38.1 cm)
B.) OPERATION
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)
(KFA80H/135H/220H Models Only)
5. Push “BTU control Switch” to “High” level. (See Figure 8.) (KFA220H Model Only)
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: (KFA135H/KFA220H Models only)
• Whentheroomtemperatureisless0℉,theLEDdisplaywillshow“Lo”
• Whenroomtempisbetween0℉and99℉,thenumbershownonthedisplayisthecurrent
room temperature.
• Whenroomtemperatureisgreaterthan99℉,theLEDdisplaywillshow“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.
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 is started at low BTU level in cold weather or low fuel
tank, ignition failure can occur.
NOTE:Incoldweather,ignitionmaybeimprovedbyholdingangerovertheendofthereliefvalveorblock
