SAFETY
INFORMATION
Carbon Monoxide Poisoning: Early
signs of carbon monoxide poisoning re-
semble the flu, with headaches, dizziness,
and/or nausea. If you have these signs, the
heater may not be working properly. Get
fresh air at once! Have heater serviced.
Some people are more affected by carbon
monoxide than others. These include preg-
nant women, persons with heart or lung
diseaseoranemia,thoseundertheinfluence
of alcohol, and those at high altitudes.
Make certain you read and understand all
Warnings. Keep this manual for reference.
It is your guide to safe and proper operation
of this heater.
• Use only kerosene or No. 1 fuel oil to
avoid risk of fire or explosion. Never
usegasoline,naphtha,paintthinners,al-
cohol, or other highly flammable fuels.
• Fueling
a)Personnelinvolved with fueling shall
be qualified and thoroughly familiar
with the manufacturer’s instructions
and applicable federal, state, and lo-
cal regulations regarding the safe
fueling of heating units.
b)Only the type of fuel specified on the
heater’s data plate shall be used.
c) All flame, including the pilot light, if
any, shall be extinguished and the
heaterallowed tocool, priortofueling.
d) During fueling, all fuel lines and fuel-
lineconnectionsshallbeinspectedfor
leaks. Any leaks shall be repaired
priortoreturningthe heater to service.
e)At no time shall more than one day’s
supply of heater fuel be stored inside
abuilding in the vicinity of the heater.
Bulk fuel storage shall be outside the
structure.
f) All fuel storage shall be located a
minimum of 25 feet from heaters,
torches, welding equipment, and
similar sources of ignition (excep-
tion: the fuel reservoir integral with
the heater unit).
g)Whenever possible, fuel storage shall
beconfined to areas where floor pen-
etrations do not permit fuel to drip
onto or be ignited by a fire at lower
elevation.
h)Fuel storage shall be in accordance
with the federal, state, or local au-
thority having jurisdiction.
• Never use heater where gasoline, paint
thinner, or other highly flammable va-
pors are present.
• Follow all local ordinances and codes
when using heater.
• Heaters used in the vicinity of tarpau-
lins, canvas, or similar enclosure ma-
terials shall be located a safe distance
fromsuch materials.Therecommended
minimum safe distance is 10 feet. It is
further recommended that these enclo-
sure materials be of a fire retardant na-
ture.These enclosure materials shallbe
securely fastened to prevent them from
igniting or from upsetting the heater
due to wind action.
• Use only in well-vented areas. Before
using heater, provide at least a three-
square-foot opening of fresh, outside
air for each 100,000 Btu/Hr of rating.
Thisheaterproducescarbonmonoxide,
which is listed by the State of Califor-
niaas a reproductive toxin under Propo-
sition 65.
• Use only in places free of flammable
vapors or high dust content.
WARNINGS
IMPORTANT: Read this Owner’s
Manual carefully and completely
before trying to assemble, oper-
ate,orservicethisheater.Improper
use of this heater can cause seri-
ous injury or death from burns,
fire, explosion, electrical shock,
and carbon monoxide poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
• Use only the electrical voltage and fre-
quency specified on model plate.
• Use only a three-prong, grounded ex-
tension cord.
• Minimum heater clearances from com-
bustibles:
Outlet: 8 Ft. Sides: 4 Ft.
Top: 4 Ft. Rear: 4 Ft.
• Locate heater on a stable and level sur-
face if heater is hot or running or a fire
may occur.
• When moving or storing heater, keep
heater in a level position or fuel spill-
age may occur.
• Keep children and animals away from
heater.
• Unplug heater when not in use.
• Whenusedwiththermostat,heatermay
start 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.

PRODUCT IDENTIFICATION
The Fuel System: The air pump forces
air through the air line. The air is then
pushed through the nozzle. This air causes
fuel to lift from the tank. A fine mist of fuel
is sprayed into the combustion chamber.
TheAirSystem: Themotorturnsthefan.
The fan pushes air into and around the
combustion chamber. This air is heated and
provides a stream of clean, hot air.
The Ignition System: The ignition con-
trolassemblyprovidespowertotheignitor.
This ignites the fuel/air mixture in the com-
bustion chamber.
The Flame-Out Control System: This
system causes the heater to shut down if the
flame goes out.

TO START HEATER
1. Follow all ventilation and safety
information.
2. Fill fuel tank with kerosene or No. 1
fuel oil.
3. Attach fuel cap.
4. Plug power cord of heater into three-
prong,groundedextensioncord. Exten-
sion cord must be at least six feet long.
STORING,
TRANSPORTING,
OR SHIPPING
Note: If shipping, transport companies re-
quire fuel tanks to be empty.
1. Drain fuel tank. Drain fuel through fuel
capopening. Be sureallfuel is removed.
2. If any debris is noted in old fuel, add 1
or 2 quarts of clean kerosene to tank,
stir, and drain again. This will prevent
excess debris from clogging filters dur-
ing future use.
3. Replace fuelcap. Properlydisposeofold
and dirty fuel. Check with local auto-
motive service stations that recycle oil.
4. If storing, store heater in dry place.
Make sure storage place is free of dust
and corrosive fumes.
IMPORTANT: Do not store kerosene over
summer months for use during next heating
season.Usingoldfuelcoulddamageheater.
Extension CordWire Size
Requirements
• 6 to 10 feet long, use 18 AWG rated
cord
• 11 to 100 feet long, use 16 AWG
rated cord
• 101 to 200 feet long, use 14 AWG
rated cord
5. Plug extension cord into standard 120
volt/60hertz,three-hole, grounded out-
let. Note: Ignitor will preheat for five
seconds then heater will start.
TO STOP HEATER
Unplug extension cord from outlet.
TO RESET HEATER
1. Unplug extension cord from outlet and
wait 10 seconds (two minutes if heater
has been running).
2. Plug extension cord into standard 120
volt/60hertz,three-hole, grounded out-
let. Note: Ignitor will preheat for five
seconds then heater will start.
