Safety Information
Indicates an imminently hazardous
Situation which, if not avoided, WILL
result in death or serious injury.
Indicates an potentially hazardous
situation which, if not avoided, COULD
result in death or serious injury.
Indicates an potentially hazardous
Situation which, if not avoided, MAY
result in minor or moderate injury.
This is a Kerosene (1-K Diesel) directed-fire forced air heater. It is
primarily intended for use for temporary heating of buildings
under construction, alteration or repair. Directed-fired means
that all of the combustion products of the heater enter the
heated space. This appliance is rated at 98% combustion
efficiency, but does produce small amounts of carbon monoxide.
Carbon monoxide is toxic.
Carbon Monoxide poisoning may lead
to death!
Humans can tolerate small amounts of carbon monoxide and
precautions should be taken to provide proper ventilation.
Failure to provide proper ventilation according to this manual
can result in death. Early signs of carbon monoxide poisoning
resemble the flu. Symptoms of improper ventilation are:
*Headache *dizziness *burning of the nose and eyes
*nausea *dry mouth *sore throat *
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 sulfur. Which can
cause a rotten egg odor during the operation of the heater,
However, #1 or #2 fuel oil - diesel 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 accommodate any added
contaminants that may be added to the heated space. Use of #1
or #2 fuel oil may result in more periodic maintenance.
Risk of indoor air pollution!
-Use this heater only in well ventilated areas ! Provide at least a
three square foot (2800 sq cm) opening of outside air for every
29KW/hr ) of heater rating
-Carbon Monoxide Poisoning. Early signs of carbon monoxide
poisoning resemble flu-like symptoms such as headaches,
dizziness, and/or nausea. If you have these symptoms, your
heater may not be working properly
-Get fresh air at once ! Have the heater serviced. Some people
are more affected by carbon monoxide than others. These
include pregnant women, those with heart or lung problems,
anemia or those under the influence of alcohol, or at high
altitudes.
R Risk of burns / fire / explosion!
-NEVER use fuels such as gasoline, benzene paint thinners, or
other oil compounds in this heater(RISK OF FIRE OR EXPLOSION)

THEORY OFOPERATION
Fuel System: This heater is equipped with an air pump that
operates off of the electric motor. The pump forces air
through the air line connected to the fuel tank, drawing fuel
to the nozzle in the burner head. Air also passes through the
nozzle where it mixes with the fuel and is sprayed into the
combustion chamber in a fine mist.
Quick-Fire Ignition: A transformer sends high voltage to a
two pronged spark plug. The spark ignition the fuel/air
mixture as it is sprayed into the combustion chamber.
Air System: A fan is turned by the heavy duty motor, which
forces air around and into the combustion chamber, where it
is super-heated and forced out the front of the chamber.
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,
Once the temperature falls below the reset temperature, you
will be able to start your heater.
Electrical System Protection:The heaters’ electrical
system is protected by a circuit breaker that protects the system
components from damage. If the heater fails, check the fuse first,
and replace if necessary
Flame Sensor: The heater uses a photocell to see the flame
in the combustion chamber. Should the flame extinguish, the
sensor will stop electrical current and the heater will shut off.
FUELING THE HEATER
It is always a good idea to fire the heater outdoors for the first
time. This will allow any oils used in the manufacturing process to
be burned off in a safe environment. This is initial burn should
last at least 10minutes.
VENTILATION
Risk of indoor air pollution. Use heater only in well ventilated
areas.
Always provide a fresh air opening in the heated space of at least
three square feet(2800 sq.cm) for each 29KW/hr of heater
output. Provide a larger opening if more heater will require.
TO START THE HEATER
1. Fill the tank with Kerosene (1-K Diesel)) until fuel
gauge point to “F”
2.Be sure fuel cap is secure.
3.Plug power cord into the local correct plug. Grounded
extension cord and plug extension cord into three prong
220-240V grounded outlet. The extension cord should be at least
six feet (1.8 meters) long.
-Extension cord wire size requirements are as follows:
-6 to 10 feet(1.8 to 3 meters),use 18 AWG wire.
-11 to 100 feet(3.4 to 30.4 meters),use 16 AWG wire.
-101 to 200 feet (30.8 to 61 meters ), use 14 AWG wire.
4.Turn thermostat control knob to desired temperature setting
(FAH-K80/K135). The setting range is
