NOTE:
4. FUEL SELECTION
1. All models can use 7 different fuels: K1 Kerosene, #1 Fuel Oil, #1, Diesel, #2 Fuel Oil, #2 Diesel, Jet A, JP-8
2. K1 Kerosene is recommended for optimal combustion and performance, and for less maintenance. K1 is also
the optimal fuel choice in extremely low temperatures of 15°F or less, as its pour-point/"gel-point" varies
3. Jet A and JP-8 are also excellent choices for clean combustion, reduced maintenance, and temperatures below
15°F, but they are rarely found outside of the aviation industry or the military.
4. #1 Fuel Oil, #1 Diesel, #2 Fuel Oil, #2 Diesel are often selected, as they are readily available. However, the
following:
a. #1 Diesel and #1 Fuel Oil will have some degree of increased smoke/soot during ignition, increased smell,
and increased regular cleaning/maintenance. , burn dirtier than #1 fuels. The
use of #2 fuels will result in a little more smoke/soot during ignition, a greater increase in smell, and will
require more regular cleaning/maintenance than #1 fuels.
c. At temperatures lower than 15°F, most diesel/fuel oil blends will become more viscous (start to gel) as
the diesel falls below its pour point (starts to "gel"), and may pose a challenge igniting the heater and with
continuous operation of the heater. There are troubleshooting steps for this situation, but selecting K1 (or
JP-8/Jet A) is recommended when operating below 15°F. The colder the temperatures the more likely you
could problems you will experience diesel gelling.
temperature drops. At 32°F, the wax in liquid form will crystallize and leave the fuel clouded; this can start
correct which can cause white smoke and performance problems.
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, JETAor 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
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.
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.
“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 HEATERFUEL TANKIN THE LIVING SPACE : FILLTHE TANK OUTDOORS.
DO NOT OVERFILLYOUR HEATER AND BE SURE HEATER IS LEVELED.
IMPORTANT NOTICEREGARDING FIRST IGNITION OF HEATER :
manufacturing the heater to burn off outside.
B.) OPERATION
TO START HEATER
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)
(KFA80/135/180/220DGD Models Only)
5. Push “BTU control Switch” to desired level “High or LOW” (See Figure 8.)
(KFA135/180/220DGD Models 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: (KFA135/180/220DGD 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.
NOTE : User can select to operate theheater on twodifferent BTUlevels(High or Low).
To stabilize heater and prevent ignition delay, select BTU level after turning theheater on,or
while it is in operation by pushing the BTUcontrol switch. If the heater started at low BTU level
in cold weather orlow fuel tank,ignition failure can occur.
NOTE : In cold weather,ignition may be improved by holding a over the end of the relief valve or
block fanguard in half with newspaper etc. until theheater ignites.
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 KFA220DGD 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)
WARNING!! : NEVER REFILLHEATER FUELTANKWHEN HEATER IS OPERATING OR STILLHOT.
NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
1. Fill fuel tank with fuel.
NOTE : Kerosene is recommended when the temperature drops below 0℉(-18℃) to prevent
ignition delay or failure.

NEVER LEAVE THE HEATER
UNATTENDED WHILE BURNING!
NOTICE : The major electrical components of this heater are protected by a safety fuse mounted to the PCB board.
If your heater fails to start, check this fuse first 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.

8. LONG TERM STORAGE OF YOUR HEATER
FUEL TANK DRAIN
1. Drain fuel tank through fuel cap opening.
(For KFA50DGD/80DGD Models Only)
2. Remove fuel drain bolt from rear bottom side of fuel tank using 3/4” socket or adjustable wrench and drain.
(For KFA135DGD/180DGD/220DGD 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.

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’S MANUAL
with the heater.
•Always cover electric outlet when not in use.
•Don’t plug and use an appliance more than 120V/60Hz 5A
