Operator’s Manual 5
CARBON MONOXIDE - POISONOUS GAS
DANGER: CARBON MONOXIDE POISONING MAY LEAD TO
DEATH!
Space heaters exhaust contains carbon monoxide - a poisonous gas
that can kill you. You CAN NOT smell or see this gas.
Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning
resemble the flu, with headaches, dizziness, and/or nausea. If you have
these signs, the space heater may not be working properly. Get fresh air at
once! Have space 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.
Never use a space heater in enclosed or partially-enclosed spaces without
proper ventilation. Use only in well-vented areas. Before using space heater,
provide at least a three-square-foot (2800 square cm) opening of fresh,
outside air for each 100,000 Btu / Hr (30 kw) of rating. Space heaters can
produce high levels of carbon monoxide very quickly. When you use a space
heater, remember that you cannot smell or see carbon monoxide. Even if you
can’t smell exhaust fumes, you may still be exposed to carbon monoxide.
If you start to feel sick, dizzy, or weak while using a space heater, get to fresh
air RIGHT AWAY. DO NOT DELAY. The carbon monoxide from space heaters
can rapidly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immediately.
Inform medical staff that carbon monoxide poisoning is suspected. If you
experienced symptoms while indoors, have someone call the re department
to determine when it is safe to re-enter the building.
NEVER operate the space heater in an explosive atmosphere, near
combustible materials or where ventilation is not sufcient to carry away
exhaust fumes. Exhaust fumes can cause serious injury or death.
NEVER run space heaters inside homes, garages, sheds, or other semi-
enclosed spaces without proper ventilation. These spaces can trap poisonous
gases EVEN IF you run a fan or open doors and windows. Use only in well-
vented areas. Before using space heater, provide at least a three-square-foot
(2800 square cm) opening of fresh, outside air for each 100,000 Btu / Hr (30
kw) of rating.
If you start to feel sick, dizzy, or weak while using the space heater, shut
if off and get fresh air RIGHT AWAY. See a doctor. You may have carbon
monoxide poisoning.
Install battery-operated carbon monoxide alarms or plug-in carbon monoxide
alarms with battery back-up in your home, according to the manufacturer’s
installation instructions. The carbon monoxide alarms should be certied to
the requirements of the latest safety standards for carbon monoxide alarms.
(UL 2034, IAS 6-96, or CSA 6.19.01).
Test your carbon monoxide alarm frequently and replace dead batteries.
6 Operator’s Manual
SAFETY WARNING WHEN REFUELING
Use only kerosene, #1#2 diesel / fuel oil, JET A or JP-8 fuels to
avoid risk of re or explosion. Never use gasoline, naphtha, paint
thinners, alcohol, or other highly flammable fuels.
Personnel involved with fueling shall be qualied and thoroughly
familiar with the manufacturer’s instructions and applicable
regulations regarding the safe fueling of heating units.
Only the type of fuel specied on the space heater’s data plate
shall be used.
All flame, including the pilot light, if any, shall be extinguished and
the space heater allowed to cool, prior to fueling.
During fueling, all fuel lines and fuel-line connections shall be
inspected for leaks. Any leaks shall be repaired prior to returning
the space heater to service.
At no time shall more than one day’s supply of space heater fuel
be stored inside a building in the vicinity of the space heater. Bulk
fuel storage shall be outside the structure.
All fuel storage shall be located a minimum of 25 feet (762cm) from
space heaters, torches, welding equipment, and similar sources
of ignition (exception: the fuel reservoir integral with the space
heater unit).
Whenever possible, fuel storage shall be conned to areas where
floor penetrations do not permit fuel to drip onto or be ignited by
a re at lower elevation.
Fuel storage shall be in accordance with the authority having
jurisdiction.
Observe all safety regulations for the safe handling of fuel.
Handle fuel in safety containers. If the container does not have a
spout, use a funnel.
Do not overll the fuel tank, leave room for the fuel to expand.
Do not rell fuel tank while the unit is running. Before refueling
the space heater, turn it off and let it cool down.
Fill the tank only on an area of bare ground. While fueling the
tank, keep heat, sparks and open flame away. Carefully clean
up any spilled fuel before starting the unit.
Always ll fuel tank in an area with plenty of ventilation to avoid
inhaling dangerous fumes.
NEVER store fuel for your space heater in the home. Gasoline,
propane, kerosene, and other flammable liquids should be stored
outside of living areas in properly-labeled, non-glass safety
containers. Do not store them near a fuel-burning appliance, such
as a natural gas water heater in a garage. If the fuel is spilled or
the container is not sealed properly, invisible vapors from the fuel
can travel along the ground and can be ignited by the appliance’s
pilot light or by arcs from electric switches in the appliance.
Operator’s Manual 7
ELECTRICAL HAZARDS
DANGER- IMPROPER CONNECTION OF THE
EQUIPMENT-GROUNDING CONDUCTOR CAN
RESULT IN A RISK OF ELECTROCUTION. CHECK
WITH A QUALIFIED ELECTRICIAN OR SERVICE
PERSON IF YOU ARE IN DOUBT AS TO WHETHER
THE UNIT IS PROPERLY GROUNDED.
Use only the electrical voltage and frequency specied on
model plate.
Space heater must be grounded. Use only a properly
grounded three-wire extension cord. Plug into grounded
outlet only. If it should malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock.
The space heater is a potential source of electrical shock if
not kept dry. Keep the space heater dry and do not use in
rain or wet conditions. To protect from moisture, operate it
on a dry surface under an open, canopy-like structure. Dry
your hands if wet before touching the space heater.
Check that the entire cord is free of cuts or tears and that
the plug has all three prongs, especially a grounding pin.

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
SPACE 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 SPACE HEATER.
Example: A 200,000 Btu / Hr (58.6kw) space heater
requires one of the following:
• a two-car garage door [16 feet (4.88 meter) opening]
raised 5 inches (12.7 cm)
• a single-car garage door [9 feet (2.74 meter) opening]
raised 8 inches (20.3 cm)
• two, 30 inch (76.2 cm) windows raised 15 inches
(38.1 cm)
FUELS
WARNING: USE ONLY KEROSENE, #1/#2 DIESEL/
FUEL OIL, JET A OR JP8 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 lter 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 space heater.
IMPORTANT: Use a KEROSENE ONLY (blue) or DIESEL
ONLY (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 space heater.
Foreign matter may also require space heater’s fuel system
to be frequently cleaned.
Preparation
Operator’s Manual 13
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 ne 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 space heater to shut down if the flame goes out.
