SAFETY
INFORMATION
WARNINGS
IMPORTANT: Read this Owner’s
Manual carefully and completely
before trying to assemble, operate, or service this heater. Improper
use of this heater can cause serious 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 resemble 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 pregnant 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, alcohol, 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 local 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 inside
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 (exception: 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 authority having jurisdiction.
• Never use heater where gasoline, paint
thinner, or other highly flammable vapors are present.
• Follow all local ordinances and codes
when using heater.
• Heaters used in the vicinity of tarpaulins, 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.
• Use only in well-vented areas. Before
using heater, provide at least a threesquare-foot opening of fresh, outside air
for each 100,000 Btu/Hr of rating. This
heater produces carbon monoxide,
which is listed by the State of California 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 frequency specified on model plate.
• Use only a three-prong, grounded extension cord.
• 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 if heater is 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.
• When used with thermostat, heater may
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.

WARNING: Use only kerosene
or No. 1 fuel oil to avoid risk of fire
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:
storage container. Be sure storage container is
clean. Foreign matter such as rust, dirt, or
water will cause the ignition control assembly
to shut down the heater. Foreign matter may
also require you to clean fuel system often.
Use a KEROSENE ONLY
VENTILATION
Follow the minimum fresh,
outside air ventilation requirements. If proper fresh, outside air
ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before 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 heaters
are being used.
Example:
quires one of the following:
• a two-car garage door (16 feet wide opening) raised three inches
• a single-car garage door (9 feet wide
opening) raised five inches
• two 30 inch wide windows raised eight
inches

THEORY OF
OPERATION
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.
The Air System: The motor turns the fan.
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 in the combustion chamber.
The Flame-Out Control System: This
system causes the heater to shut down if the
flame goes out.
