Theory of Operation
Fuel System: This heater is equipped with a high-pres-
sure pump. The pump draws fuel up from the fuel tank to
the nozzle in the burner head. It is sprayed into the
combustion chamber in a fine mist where it is mixed with
air for combustion.
Quick-Fire Ignition: A transformer sends high voltage to a
two-pronged spark plug. The spark ignites the fuel/air
mixture as it is sprayed into the combustion chamber.
Air System: A blower motor assembly forces air around
the combustion chamber, where it is super-heated and
forced out the front of the chamber. A cooling fan blows air
up and around the chamber during operation and also
runs during the cool-down period.
Electrical System Protection: The heater’s 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 (see page
10).
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.
Unpacking Heater
1. Attach handle by lining up holes of handle with the holes
in the upper shell of heater (See figure 4).
2. Insert screws and tighten.
3. Remove the heater and all of the packaging materials
from the shipping carton.
NOTE: Save the box and packaging materials for future
storage.
Fuel (1-K Kerosene)
For optimal performance of this heater, it is strongly
suggested that 1-K kero sene be used. 1-K kerosene has
been refined to virtually eliminate contami nants, such as
sulfur, which can cause a rotten egg odor during the
operation of the heater. However, #1 or #2 fuel oil (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 accommodate any added contaminants
that may be added to the heated space. Using diesel fuel
can cause excess soot production. DO NOT use any fuel
that is not approved above. Do not use Bio-Diesel as this
fuel will damage your heater’s seals and filter.
Kerosene should only be transported or stored in a
blue container that is clearly marked “kerosene”.
Never store kerosene in a red container, because red
containers are associated with gasoline.
Never store kerosene in a living area. Kerosene should
always be stored in a well ventilated area outside of the
living space.
Never store kerosene in direct sunlight or near any
heating source.
Never use kerosene that has been stored from one
season to the next. Kerosene does break down over time.
Old kerosene will not burn properly in this heater.
Use of old or contaminated kerosene can lead to
excessive soot production.
Fueling the Heater
Never fill the fuel tank indoors. Always fill the tank
outdoors. Be sure that the heater is on level ground
when fueling, and never overfill the fuel tank.
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 initial
burn should last at least 10 minutes.
Never use fuels such as gasoline,
benzine, alcohol, white gas, camp stove
fuel, paint thinners or other oil products to fuel this heater.
These are volatile fuels that could cause an explosion or
uncontrolled flame.

Never refuel this heater while it is hot or
operating. Fire or explosion could result.
Never transport this heater in a vehicle while containing
fuel.
