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.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness, 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 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 (7.62 m) 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 pen-
etrations do not permit fuel to drip onto or be ignited by a fire at lower eleva-
tion.
h) Fuel storage shall be in accordance with the 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 materi-
als shall be located a safe distance from such materials. The recommended
minimum safe distance is 10 feet (3.048 m). It is further recommended that
these enclosure materials be of a fire retardant nature. These enclosure mate-
rials shall be securely fastened to prevent them from igniting or from upset-
ting the heater due to wind action.
•Use only in well-vented areas. Provide at least a 4 1/2-square-foot (4,180 square
cm) opening of fresh outside air.
•Use only in places free of flammable vapors or high dust content.
•Use only with 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. (244 cm) Sides, Top, and Rear: 4 Ft. (122 cm)
•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.
•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.

Tools Needed
•Medium Phillips Screwdriver
•3/8" Open or Adjustable Wrench
•Hammer
1. Slide axle through wheel support frame. Install wheels on axle.
IMPORTANT: When installing wheels, point extended hub of wheels toward
wheel support frame (see Figure 2).
2. Place cap nuts on axle ends. Gently tap with hammer to secure.
3. Place heater on wheel support frame. Make sure air inlet end (rear) of heater is
over wheels. Line up holes on fuel tank flange with holes on wheel support
frame.
4. Place front handle on top of fuel tank flange. Insert screws through handle,
fuel tank flange, and wheel support frame. Attach nut finger tight after each
screw is inserted.
5. After all screws are inserted, tighten nuts firmly.

THEORY OF
OPERATION 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 Burner Control System: This system causes the heater to shut down if
the flame goes out.

VENTILATION
!
WARNING
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.
FUELS
!
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 nontoxic anti-icer in fuel during very cold weather
IMPORTANT: Use a KEROSENE ONLY storage container. Be sure storage
container is clean. Foreign matter such as rust, dirt, or water will cause the burner
control to shut down heater. Foreign matter may also require you to clean fuel
system often.
Provide a fresh air opening of at least 4 1/2 square feet (4,180 square cm). Provide
extra fresh air if more heaters are being used.
Example: A 150,000 Btu/Hr heater requires one of the following:
•a two-car garage door [16 feet (5 meter) wide opening] raised 3.5 inches
(8.9 cm)
•a single-car garage door [9 feet (2.75 meter) wide opening] raised 6 inches
(15.25 cm)
•two, thirty-inch (76.2 cm) wide opening windows raised 11 inches (28 cm)

OPERATION
!
WARNING
Review and understand the warnings in the Safety
Information Section. 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 220 volt/60 hertz grounded outlet. Use an
extension cord if needed. Use only a three-prong, grounded (earthed) exten-
sion cord.
Extension Cord Wire Size Requirements
Up to 100 feet (30.5 meters) long, use 16 AWG (1.0 mm2) rated cord
101 to 200 feet (30.8 to 61 meters) long, use 14 AWG (1.5 mm2) rated cord
Heater will start when power cord is plugged into outlet. If not, push in burner
control reset button (see Figure 4).

To Stop Heater
1. Unplug power cord from outlet.
To Restart Heater
1. Wait 2 minutes after stopping heater.
2. Repeat steps under To Start Heater, above.

103252
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 (1 or 2 liters) 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.
IMPORTANT: Do not store kerosene over summer months for use during next
heating season. Using old fuel could damage heater.
