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 to New York City Residents
For Use Only At Construction Sites
in accordance with applicable NYC codes
under NYCFD certificate of approval
#4803, #4899, #4908, #4909, or #4934.

ASSEMBLY
These models are furnished with wheels and
a front handle. Some models are furnished
with a rear handle also. Wheels, handle(s),
and the mounting hardware are found in the
shipping carton.
Tools Needed
• Medium Phillips Screwdriver
• 3/8" Open or Adjustable Wrench
• Hammer
1. Slide axle through wheel support
frame. Install wheels on axle.
IMPORTANT:
point extended hub of wheels toward
wheel support frame (see Figure 2).
When installing wheels,
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 if
provided) on top of fuel tank flange.
Insert screws through handle(s), 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.

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:
storage container. Be sure storage container
is 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.

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 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 (16 feet wide opening) raised five inches
• a single-car garage door (9 feet wide
opening) raised eight inches
• two windows (30 inches wide opening)

OWNER’S MANUAL
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.

STORING,
TRANSPORTING,
OR SHIPPING
Note:
If shipping, transport companies re-
quire fuel tanks to be empty.
1. Drain fuel tank.
Note:
This model has a drain plug on
underside of fuel tank. Remove drain
plug to drain all fuel. Be sure all fuel is
removed.
2. Replace drain plug.
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 and 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:
summer months for use during next heating
season. Using old fuel could damage heater.
Do not store kerosene over
