OPERATION
Figure 9 – Overview of Heater Design
OVERVIEW OF HEATER DESIGN
Fuel System: This heater is equipped with a fuel pump (Gear) that
pulls fuel through the fuel line connected to the fuel tank and then
pushes fuel through a filter and a solenoid valve and out the burner
head nozzle.
This fuel is sprayed into the combustion chamber in a fine mist.
SureFire Ignition: The electronic ignitor sends voltage to a
specially designed spark plug. The spark plug ignites the fuel
and air mixture.
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.

Electrical System Protection:
protected by a circuit breaker mounted to the power switch that
protects PCB assembly and other electrical components from damage.
Flame-Out Sensor: Utilizes a photocell to monitor the flame in
burn chamber during normal operation. It will cause the heater
to shut off should the burner flame extinguish.
FUEL SPECIFICATIONS
KEROSENE (1-K)
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.
■
Kerosene should only be stored in a blue container that is
clearly mark ed "kerosene". Never store kero sene in a red
container. Red is associ ated with gasoline.
■
NEVER store kerosene in the living space. Kerosene should
be stored in a well ventilated area outside the living area.
■
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 A FIRE OR EXPLOSION).
■
NEVER store kerosene in direct sunlight or near a source of
heat.

season to the next. Kerosene deteriorates over time. OLD
KEROSENE WILL NOT BURN PROPERLY IN THIS HEATER.
■
Use 1-K kerosene in this heater. #1 fuel is a suitable
substitute.
