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 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. 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 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 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 authority hav-
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
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.
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.
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: 250 cm (8 Ft.) Sides, Top, and Rear: 125 cm (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.

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 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
• use of non-toxic anti-icer in fuel during very cold weather
IMPORTANT:
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.
Use a KEROSENE ONLY container. Be sure

VENTILATION THEORY OF OPERATION
ASSEMBLY
(FOR BY100CEH AND BY150CEH MODELS ONLY)
These models are furnished with wheels and handles. Wheels, handles, 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:
wheels toward wheel support frame (see Figure 3).
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 on top of fuel tank flange. Insert screws through handles, 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.

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 a fresh air opening of at least 2800 square cm (three square feet) for each 30kw (100,000 Btu/Hr) rating. Provide extra fresh air if more heaters are being used.
Example:
A 44kw (150,000 Btu/Hr) heater requires one of the
following:
• a two-car garage door [4.9 meter (16 feet) opening] raised 9 cm (3.5 inches)
• a single-car garage door [2.75 meter (9 feet) opening] raised 15.25 cm (6 inches)
• two, 76 cm (30 inch) windows raised 28 cm (11 inches)

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 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.

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 standard 240 volt/50 hertz,
EXTENSION CORD WIRE SIZE REQUIREMENTS
Up to 30.5 meters (100 feet) long, use 1.0 mm2 (16 AWG) conductor
30.6 to 61 meters (101 to 200 feet) long, use 1.5 mm2 (14 AWG) conductor
Push ON/OFF switch to ON (|) position and heater should start in 5 seconds. If ON/OFF switch light does not come on or heater does not start, see Troubleshooting (pages 6 and 7).

STORING, TRANSPORTING, OR SHIPPING
Note:
If shipping, transport companies require fuel tanks to be
empty.
1. Drain fuel tank.
Note:
Some models have drain plug on underside of fuel tank. If so, remove drain plug to drain all fuel. If heater does not have drain plug, drain fuel through fuel cap opening. Be sure all fuel is removed.
2. Replace drain plug if provided.
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 or 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:
during next heating season. Using old fuel could damage heater.
Do not store kerosene over summer months for use
TO STOP HEATER
Push ON/OFF switch to OFF (O)position.
TO RESET HEATER
1. Push ON/OFF switch to OFF (O) position and wait 10 sec­onds (2 minutes if heater has been running).
2. Repeat steps under To Start Heater, above.
