SAFETY
INFORMATION
WARNINGS
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 fuelline 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.

Figure 1 - 55,000 Btu/Hr Model Shown
THEORY OF OPERATION
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.
Combustion Chamber
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.

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
• 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 ignition control assembly
to shut down the heater. Foreign matter may
also require you to clean fuel system often.
Power Cord
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
lift from the tank. A fine mist of fuel is
sprayed into the combustion chamber.
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.
3
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 at least a two-square-foot opening
of fresh, outside air for each 55,000 Btu/Hr
rating. Provide extra fresh air if more heaters are being used.
Example: A 55,000 Btu/Hr heater requires
one of the following:
• a two-car garage door (16-feet-wide
opening) raised 1 1/2 inches
• a single-car garage door (9-feet-wide
opening) raised 2 1/2 inches
• two windows (30-inches-wide opening)
raised 4 1/2 inches

STORING,
TRANSPORTING,
OR SHIPPING
Note: If shipping, transport companies require fuel tanks to be empty.
1. Drain fuel tank. Drain fuel through fuel
cap opening. Be sure all fuel is removed.
2. 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.
3. Replace fuel cap. Properly dispose of old
and dirty fuel. Check with local automotive service stations that recycle oil.
4. 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.
WARNING: Never service
heater while it is plugged in, operating, or hot. Severe burns and
electrical shock can occur.
