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.

INFORMATION

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 federal, state, and local regula-
tions 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 stor age shall be outside the struc-
ture. 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 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 federal, state, or local authority ha v-
ing 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 three-square­foot 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.

1. Remove all packing items applied to heater for shipment.
2. Remove all items from carton.
3. Check items for shipping damage. If heater is damaged, promptly inform dealer where you bought heater.
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.
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.

FUELS
WARNING
Use only kerosene or No. 1 fuel oil to avoid risk of re or explosion. Never use gasoline, naphtha, paint thinners, alcohol, or other highly ammable 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
• the need of non-toxic anti-icer in fuel during very cold weather
IMPORTANT:
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.
Use a KEROSENE ONLY storage container. Be sure storage
VENTILATION
OPERATION
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 50,000 Btu/Hr rating. Provide extra fresh air if more heaters are being used.
Example:
A 50,000 Btu/Hr heater requires one of the following:
• a 16 foot two-car garage door raised two inches
• a 9 foot single-car garage door raised three inches
• two, thirty-inch windows raised five inches
WARNING
Review and understand the warnings in the Safety Informa­tion Section, pages 2 and 3. 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 three-prong, grounded extension cord. Exten­sion cord must be at least six feet long.
Extension Cord Wire Size Requirements
6 to 10 feet long, use 18 AWG rated cord 11 to 100 feet long, use 16 AWG rated cord 101 to 200 feet long, use 14 AWG rated cord
5. Plug extension cord into standard 120 volt/60 hertz, three-hole, grounded outlet.
Note:
Ignitor will preheat for five seconds then heater will start.
102553
To Stop Heater
1. Unplug extension cord from outlet.
To Restart Heater
1. Wait ten seconds after stopping heater.
2. Repeat steps under To Start Heater (see above).

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.
