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.

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 regulations regarding the safe fu-
eling 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 struc-
ture.
f) All fuel storage shall be located a minimum of 762cm (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 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 304.8cm (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-square-foot) opening of fresh, outside air for each 100,000 Btu/Hr of rating.
• 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: 250 cm (8 Ft.)Sides, Top, and Rear: 125 cm (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.
• Heater is equipped with a thermostat and 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. Using duct work could reduce the
necessary air flow of the heater. Heater would produce excessive carbon monoxide.

• Hammer
1. Slide axle through wheel support frame. Install wheels on axle.
I
MPORTANT:
wheel support frame (see Figure 3).
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 and rear handle on top of fuel tank flange. Insert screws
through handles, fuel tank flange, and wheel support frame. Attach nut finger
tight after each screw is inserted.

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 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
• use of non-toxic anti-icer in fuel during very cold weather
IMPORTANT:
clean. Foreign matter such as rust, dirt, or water will cause the flame-out control to
shut down heater. Foreign matter may also require you to clean fuel system often.

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.
Provide a fresh air opening of at least 2800 square cm (three square feet) for each
100,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.

A 150,000 Btu/Hr heater will require at least 4,200 square cm (4.5
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 standard 220 volt/50 hertz, grounded (earthed)
outlet. Use an extension cord if needed. Use only a three-prong, grounded
(earthed) extension cord.
Extension Cord Wire Size Requirements
Up to 30.5 meters (100 feet) long, use 1.0 mm2 (16 AWG) conductor
30.6 to 61 meters (101 to 200 feet) long, use 1.5 mm2 (14 AWG) conductor
Heater will start when power cord is plugged into outlet. If not, push in flame-
out control reset button (see Figure 5).
5. Adjust thermostat to desired setting. If heater does not start, thermostat may be
set too low. Turn thermostat knob to higher position to start heater. If thermostat is in HIGH position and heater still will not start, push in flame-out
control reset button (see Figure 5).

STORING,
TRANSPORTING,
OR SHIPPING
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, page 7.
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 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.
