THEORY OF OPERATION
THE FUEL SYSTEM
The motor turns the fuel pump. The
fuel pump pulls fuel from the fuel
tank. The fuel pump pushes fuel
through a filter and a solenoid valve
and out the burner head nozzle. A fine
mist of fuel is sprayed into the combus-
tion chamber.

Air Out
• Heater must be grounded. Use only a
properly grounded three-wire exten-
sion cord. Plug into grounded outlet
only.
• Never start heater when combustion
chamber is hot or if fuel has accumu-
lated in combustion chamber.
• Never use gasoline, crankcase
drainings, naphtha, paint thinners,
alcohol, or other highly flammable
fuels.
• Never leave a heater plugged in
without adult supervision if children
or animals are likely to be present.
• Heaters used in the vicinity of tarpau-
lins, canvas, or similar enclosure
materials shall be located a safe
distance from such materials. The
recommended minimum safe distance
is 10 feet. It is further recommended
that these enclosure materials be of a
fire retardant nature. These enclosure
materials shall be securely fastened to
prevent them from igniting or from
upsetting the heater due to wind
action.
• Minimum heater clearances from
combustibles:
Outlet: 8 Ft. Sides: 4 Ft.
Top: 4 Ft. Rear: 4 Ft.
• Locate heater on a stable and level
surface while hot or running or a fire
may occur.
• When moving or storing heater, keep
heater in a level position or fuel
spillage may occur.
• Keep children and animals away from
heater.
• Unplug heater when not in use.
• This heater has a built-in thermostat.
Plugged-in heater may start at
anytime.
• Never use heater in living or sleeping
areas.
• Never block air inlet (rear) or air
outlet (front) of heater.
• Never move, handle, refuel, or
service a hot, operating, or plugged-
in heater.
• Never attach duct work to front or
rear of heater.
• Warning to New York City Residents For
Use Only At Construction Sites in accor-
dance with applicable NYC codes under
NYC Board of Standards and appeals

THE AIR SYSTEM
The motor turns the fan. The fan
pushes air into and around the combus-
tion chamber. This air is heated and
provides a stream of clean, hot air.
THE IGNITION SYSTEM
The electronic ignitor sends voltage to
the spark plug. The spark plug ignites
the fuel and air mixture.
THE FLAMEOUT CONTROL SYSTEM
This system causes the heater to shut
down if the flame goes out. It also
allows the fan to continue running
after normal shutdown of heater. This
cools the combustion chamber.
