SAFETY
INFORMATION

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.
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.

SAFETY
INFORMATION
Continued
• 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 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 25 feet from heaters, torches,
welding equipment, and similar sources of ignition (exception: the fuel reser-
voir integral with the heater unit).
g) Whenever possible, fuel storage shall be confined t o 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
having jurisdiction.
• Never use heater where gasoline, paint thinner, or other highly flammable
vapors are present. Never use heater in areas with high dust content.
• Minimum heater clearances from combustibles:
Outlet: 8 Ft. Sides: 4 Ft. Top: 4 Ft. Rear: 4 Ft.
• 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. Provide at least three square feet 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 a three-prong, grounded extension cord. Use only with the electrical
voltage and frequency specified on model plate.
• Unplug heater when not in use.
• Never block air inlet (rear) or air outlet (front) of heater. Never attach duct
work to front or rear of heater.
• Locate heater on a stable and level surface while hot or running or a fire may occur.
• When moving or storing heater, keep heater in a level position or fuel spillage
may occur.
• Never move, handle, refuel, or service a hot, operating, or plugged-in heater.
• When used with thermostat, heater may start anytime.
• Keep children and animals away from heater.
• Never use heater in living or sleeping areas.
• Follow all local ordinances and codes when using heater.

UNPACKING
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.
ASSEMBLY
(For 110,000 and 150,000
BTU/Hr Models Only)
These models are furnished with wheels and a front handle. Some models are
furnished with a rear handle also. Wheels, handle(s), 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:
wheel support frame (see Figure 4).
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 if provided) on top of fuel tank flange.
Insert screws through handle(s), 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.
When installing wheels, point extended hub of wheels toward

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 system (part of the flame control) sends
voltage to the spark plug. The spark plug ignites the fuel and air mixture.
The Flame Control System: This system monitors the combustion process
inside the heater. The flame control will shut down the heater when it is out of
fuel or when flame is unstable.

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
• carbon build up on spark plug
• 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 flame
control to shut down heater. Foreign matter may also require you to clean fuel
system often.

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 three square feet for each 100,000 BTU/Hr
rating. Provide extra fresh air if more heaters are being used.
Example:
• a two-car garage door raised six inches
• a single-car garage door raised nine inches
• two, thirty-inch windows raised twelve inches
A 150,000 BTU/Hr heater requires one of the following:
