4. KEROSENE (1-K)
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
the operation of the heater. However, #1 or #2 diesel fuel may also be used if 1-K kerosene is 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.
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 petrol.
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 diesel fuel is an acceptable substitute.)
NEVER use fuel such as petrol, 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.
NOTE : Heater should be inspected before each use, and at least annually by a qualified service person.

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 : The heaters electrical system is protected by a circuit breaker mounted to
the power switch that protects the PCB assembly 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 the burn chamber during normal operation.
It will cause the heater to shut-off should the burner flame extinguish.
6.
DO NOT OVERFILL YOUR HEATER AND BE SURE HEATER IS LEVELED. IMPORTANT
NOTICE 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 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 2,800 sq. cm (3 sq. feet) for each 100,000 BTU rating.
Provide extra fresh air if more heaters are being used.
Example : A IH75000 heater requires one of the following:
•a two-car garage door raised 15.24 cm (six inches)
•a single-car garage door raised 22.86 cm (nine inches)
•two, 76.20 cm (thirty-inch) windows raised 38.1 cm (fifteen inches)
B.) OPERATION
TO START HEATER
1. Fill fuel tank with kerosene or #1 diesel fuel.
2. Attach fuel cap.
3. Plug power cord of heater into three-pin, earth grounded extension cord. Extension cord must be at
least six feet long.
Extension Cord Wire Size Requirements :
•1.8 to 3 meters (6 to 10 feet) long, use 18 AWG conductor.
•3.4 to 30.5 meters (11 to 100 feet) long, use 16 AWG conductor.
•30.8 to 61 meters (101 to 200 feet) long, use 14 AWG conductor.
4. Turn “THERMOSTAT CONTROL KNOB” to desired setting (setting range : 5 ~45 ) and push
power switch to ON” position, power indicator lamp will light and heater will start.
NOTE : Room Temp. display indicates as follows,
* When room temp. is less than 5 : "Lo"
* When room temp. is between 0 and 45 : Indicates room temperature.
* When room temp. is more than 45 : "Hi"
If heater does notstart, the thermostat setting may be too low,turn "THERMOSTAT CONTROLKNOB" to
higher positon to start heater. If heater still does notstart, turn power switch to "OFF" and then to "ON"
position.(See Figure9). If heater still does notstart,see Troubleshooting Guide on page 16.
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.
