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.

WARNINGS
• 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 regula-
tions 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 stor age shall be outside the struc-
ture.
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 penetra-
tions 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 hav-
ing 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 three-squarefoot 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.

1. Remove all packing items applied to heater for shipment.
2. Remove all items from carton.
3. Check items for shipping damage. If heater is damaged, promptly inform
dealer where you bought heater.
The Fuel System: The air pump forces air through the air line. The air is then
pushed through the burner head 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 electronic ignitor sends voltage to the spark plug.
The spark plug ignites the fuel and air mixture.
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 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:
• clogged fuel filter and nozzle
• carbon build up on spark plug
• the need of non-toxic anti-icer in fuel during very cold weather
VENTILATION
IMPORTANT:
container is clean. Foreign matter such as rust, dirt, or water will cause the flameout control to shut down heater. Foreign matter may also require you to clean fuel
system often.
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:
• a two-car garage door (sixteen foot width) raised at least two inches
• a single-car garage door (nine foot width) raised at least three inches
• two, thirty-inch windows raised at least four inches
Use a KEROSENE ONLY storage container. Be sure storage

WARNING
Review and understand the warnings in the Safety
Information Section, pages 2 and 3. They are needed to
safely operate this heater. Follow all local codes when
using this heater.
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, grounded extension cord. Exten-
sion cord must be at least six feet long.
Extension Cord Wire 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/60 hertz, three-hole, grounded
outlet. Heater will start when extension cord is plugged into outlet. If not,
push in flame-out control reset button (see Figure 3).

STORING,
TRANSPORTING,
OR SHIPPING
Note:
If shipping, transport companies require fuel tanks to be empty.
1. Drain fuel tank.
Note:
Some models have drain plug on underside of fuel tank. If so, remove
drain plug to drain all fuel. If heater does not have drain plug, drain fuel
through fuel cap opening. Be sure all fuel is removed.
2. Replace drain plug if provided.
3. 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
during future use.
4. Replace fuel cap or drain plug. Properly dispose of old and dirty fuel. Check
with local automotive service stations that recycle oil.
5. If storing, store heater in dry place. Make sure storage place is free of dust and
corrosive fumes.
