SAFETY
INFORMATION
,_ 1WARNINGS
IMPORTANT: Read this Owner's
Manual carefully and completely
before trying to assemble, oper-
ate,orservice thisheater. 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!
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
disease or anemia, those under the influence
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
use gasoline, naphtha, paint thinners, al-
cohol, or other highly flammable fuels.
Fueling
a) Personnel involved 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
heater allowed to cool, prior to fueling.
d)During fueling, all fuel lines and fuel-
line connections shall be inspected for
leaks. Any leaks shall be repaired
prior to returning the heater to service.
e) At no time shall more than one day's
supply of heater fuel be stored in-
side a building 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 be confined to areas where
floor penetrations 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
from such materials. The recommended
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 shall be
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.
This heater produces carbon monox-
ide, which is listed by the State of Cali-
fornia as a reproductive toxin under
Proposition 65.
Use only in places free of flammable
vapors or high dust content.
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
combustibles:
Outlet: 8 Ft. Sides: 4 Ft.
Top: 4Ft. 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.
When used with thermostat, heater may
start anytime.
Never use heater in living or sleep-
ing 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.

THEORY OF OPERATION
The Fuel System: The air pump forces
air through the air line. The air is then
pushed through the nozzle. This aircauses
fuel to lift from the tank.A finemist of fuel
is sprayed into the combustion chamber.
The Air System: The motor tarns thefan.
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-
trol assembly provides power to the ignitor.
This ignites the fuel/air mixture inthe com-
bustion chamber.
The Flame-Out Control System: This
system causes the heater to shut down if the
flame goes out.

_WARNING: Use only kerosene
or No. 1 fuel oilto avoid risk offire
or explosion. Never use gasoline,
naphtha, paint thinners, alcohol,
or other highly flammable fuels.
Do not use heavy fuels such as No. 2 fuel oil
or No. 2 Diesel. Using heavy fuels will
result in a clogged fuel filter and/or nozzle.
IMPORTANT: Use a KEROSENE ONLY
storagecontainer. Be sure storagecontainer is
clean. Foreign matter such as rest, dirt, or
water will causethe ignitioncontrol assembly
to shut down the heater. Foreign matter may
also require you to clean fuel system often.
VENTILATION
_[_ WARNING: Follow the mini-
mum fresh, outside air ventila-
tion requirements. Ifproper fresh,
outside air ventilation is not pro-
vided, carbon monoxide poison-
ing can occur. Provide proper
fresh, outside air ventilation be-
fore running heater.
Provide at least a three-square-foot opening
of fresh, outside air for each 100,000 Btu/Hr
rating. Provide extra fresh air if more heat-
ers are being used.
Example: A 60,000 BttffHr heater requires
one of the following:
•atwo-car garage door (16 feet wide open-
ing) raised i th"inches
•a single-car garage door (9 feet wide
opening) raised 2 _/z" inches
•two windows (30 inches wide opening)
raised 4 t/.,- inches

41& WARNING: Review and un-
derstand the warnings in the
Safety Information section, page
2. They are needed to safely op-
erate this heater. Follow all local
codes when uslng this heater.
TO START HEATER
1. Follow all ventilation and safety
information.
2. Fill fue! tank with kerosene or No. 1
fuel oil.
3. Attach fuel cap.
4. Plug power cord of heater into three-
prong, grounded extension cord. Exten-
sion cord must be at least six feet long.
5.
Extension Cord Wire Size
Requirements
•6 to 10 feet long, use i8 AWG rated
cord
• 11 to 100 feet long, use 16 AWG
rated cord
• 101 to 200 feet long, use 14 AWG
rated cord
Plug extension cord into standard 120
volt/60 hertz, 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 fromoutlet and
wait 10 seconds (two minutes if heater
h_t_en running).
2. Plug extension cord into standard 120
volt/60 hertz, three-hole, grounded out-
let. Note: Ignitor will preheat for five
seconds then heater will start.
STORING,
TRANSPORTING,
OR SHIPPING
Note: If shipping, transport companies re-
quire fuel tanks to be empty.
1. Drain fuel tank. Drain fuel through fuel
cap opening. Be sure all fuel 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 fuel cap. Properly dispose of old
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. Using old fuel could damage heater.
