Figure 6 - Overview of Heater Design
OVERVIEW OF HEATER 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 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
SureFire 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
Temperature Limit Control: This heater is equipped with
a Temperature Limit Control designed to turn the heater
off 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.
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
Flame-Out Sensor:
bun chamber during normal operation. It will cause the heater

1. All models can use 7 different fuels: K1 Kerosene, #1 Fuel
Oil, #1, Diesel, #2 Fuel Oil, #2 Diesel, Jet A, JP-82.
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 depend-ing on the
refinery, but it is always far below the lowest temperatures
reached North America.
3. Jet A and JP-8 are also excellent choices for clean combus-
tion, 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 uwer
must under-stand that Fuel Oil and Diesel are less refined,
and therefore the user should be aware of 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/mainte-nance.
b. #2 Diesel and #2 Fuel Oil will, generally depending on the
regional refinery, 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/-mainte-nance 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 continu-ous 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.
d. Diesel fuel gelling happens when the paraffin usually present
in diesel starts to solidify when the temperature drops. At
32°F, the wax in liquid form will crystallize and leave the fuel
clouded; this can start to have an effect on the fuel filter and
the nozzle. If the nozzle is getting coated the spray pattern
willnot be correct which can cause white smoke and
perfor-mance problems.

OPERATION (cont.)
Figure 7.1 - Controls
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 the heater is level,
IMPORTANT:REGARDING FIRST IGNITION OF HEATER.
The first time you light the heater, it should be done
OUTDOORS. This allows the oils, etc., used in
manufacturing heater to be burned off outside.
TO START HEATER
1.Fill fuel tank with fuel.
NOTE : Kerosene is recommended when the
temperature drops below 0˚F(-18˚C) to
prevent ignition delay or failure.
2.Attach fuel cap.
3.Plug power cord 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 30.53 meters) long, use 16
AWG conductor.
- 101 to 200 feet (30.8 to 61 meters) long, use 14
AWG conductor.
NO THERMOSTAT ON 50
4.Turn thermostat control knob to desired setting and
push power switch to “ON” position. Power lamp will
light and heater will start.
NOTE:Room Temp. display indicates as following:
- When room temp. is less than 0˚F: “lo”.
- When room temp. is between 0˚F and 99˚F:
“Temp. is Displayed”
- When room temp is greater than 99˚F : “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
(See Figure 7.1 &7.2). If heater still does not start, see
Troubleshooting on page 18.
NOTE: 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.
NOTE: In cold weather, ignition may be improved by holding
a finger over the end of the relief valve or block fan guard in
half with newspaper etc. until the heater ignites.
TO SHUT DOWN HEATER
Turn switch to “OFF” and unplug power cord.

KEROSENE SHOULD ONLY BE STORED IN A BLUE
CONTAINER THAT IS CLEARLYMARKED
“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 substi-
tutes)
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 BURN PROPERLY IN
THIS HEATER.
