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, #1/#2 diesel/fuel oil, JET A or JP-8 fuels
to avoid risk of fire or explosion. Ne v er use gasoline, naphtha,
paint thinners, alcohol, or other highly flammable fuels.
•Fueling
a)Personnel involv ed with fueling shall be qualif ied and thor -
oughly 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 extin-
guished and the heater allowed to cool, prior to fueling.
d) During fueling, all fuel lines and fuel-line connections shall
be inspected for leaks. An y 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 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 ar-
eas 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 authority hav-
ing jurisdiction.
•Use only the electrical voltage and frequency specified on
model plate.
•Heater must be grounded. Use only a properly grounded threewire extension cord. Plug into grounded outlet only.
•Use only in areas free of flammable vapors or high dust content.
•Minimum clearance from any combustible materials: 8 feet
(244 cm) from hot air outlet; 6 feet (183 cm) from top; and 2
feet (61 cm) from sides and inlet.
•Locate heater on a stable and level surface while hot or operating or a fire may occur.
•Use only in well-vented areas. Before using heater, provide at
least a 2800 square cm (three-square-foot) opening of fresh,
outside air for each 30 kw (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.
•Keep children and animals away from heater at all times.
•Never start heater when combustion chamber is hot or if fuel
has accumulated in combustion chamber.
•When used with thermostat, heater may start at anytime.
•When heater is moved or stored, it must be in a level position
or fuel spillage may occur.
•Use heater only in accordance with local ordinances and codes.
•Never use gasoline, crankcase drainings, naphtha, paint
thinners, alcohol, or other highly flammable fuels.
•Never use heater where gasoline, paint thinner , or other highly
flammable vapors are present.
•Never use heater in living or sleeping areas.
•Never leave a heater plugged in without adult supervision if
children or animals are likely to be present.
•Never move, handle, refuel, or service a hot, operating, or
plugged-in heater.
•Never attach duct work to front or rear of heater.
•Never attach heater to external fuel tank.
•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.
•Unplug heater when not in use.
•Never block air inlet (rear) or air outlet (front) of heater.
•Warning to New York City ResidentsFor Use Only At Construction Sites in accordance with ap-
plicable NYC codes under NYCFD certificate of approval
#4803, #4899, #4908, #4909, or #4934.

UNPACKING
1.Remove all packing items applied to heater for shipment.
2.Remove all items from carton.
3.Check items for any shipping damage. If heater is damaged,
promptly inform dealer where you bought heater.
FUELS
WARNING: Use only kerosene, #1/#2 diesel/fuel
oil, JET A or JP-8 fuels to avoid risk of fire or explosion. Never use gasoline, oil drained from crankcases, naphtha, paint thinners, alcohol or other highly
flammable fuels.
Use only kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels.
Heavier fuels such as No. 2 fuel oil or No. 2 diesel fuel may also be
used but will result in:
• noticeable odor
• additional fuel filter maintenance
• the need for nontoxic, anti-icer additives in very cold weather
Do not use fuels heavier than No. 2 grade or heavy oils such as oil
drained from crankcases. These heavy oils will not ignite properly
and will contaminate the heater.
IMPORTANT:
(yellow) 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 heater. Foreign matter may also require
heater's fuel system to be frequently cleaned.
Use a KEROSENE ONLY (blue) or DIESEL ONLY
Rear Panel
VENTILATION
WARNING: Provide a fresh air opening of at least
three square feet (2,800 square cm) for each 100,000
BTU/HR rating. Provide extra fresh air if more heaters
are being used. The minimum ventilation requirements must be followed to avoid risks associated
with carbon monoxide poisoning. Make certain these
requirements are met prior to operating heater.
Example:
following:
• a two-car garage door [4.88 meter (16 feet) opening] raised
12.7 cm (5 inches)
• a single-car garage door [2.74 meter (9 feet) opening] raised
20.3 cm (8 inches)

ASSEMBLY
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 be lifted
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 control 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.

OPERATION WITH PORTABLE
GENERATOR
WARNING: Before operating heater or any appliance from a portable generator, verify that generator
has been properly connected to earth ground. Improper grounding or failure to ground generator can
result in electrocution if a ground fault occurs. Refer
to owner’s manual supplied by generator manufacturer for proper grounding procedures.
The operating voltage range of the heater is 108 to 132 Volts (120
Volts +/- 10%). Prior to plugging heater into generator the output
voltage should be verified (if generator is equipped with the automatic
idle feature, the output voltage should be measured with the generator
running at full speed). If the voltage does not measure in this range the
heater should not be plugged into the generator.
Refer to Operation for starting, stopping, and resetting heater
procedures.

STORING, TRANSPORTING,
OR SHIPPING
Note:
If shipping, transport companies require fuel tanks to be empty.
1. Remove drain plug from bottom side of fuel tank and drain
all fuel.
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.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:
during next heating season. Using old fuel could damage heater.
Do not store kerosene over summer months for use
