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, electrocution, and carbon monoxide
poisoning.
•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.
•Never use heater where gasoline, paint thinner, or other highly flammable
vapors are present.
•Follow all local ordinances and codes when using heater.
•Use only in well vented areas. Provide at least three square feet (2800 square
cm) of fresh, outside air for each 100,000 BTU/Hr of rating.
•Use only in places free of flammable vapors or high dust content.
•Use only with the electrical voltage and frequency specified on model plate.
•Use only a three-wire, grounded (earthed) extension cord.
•Minimum heater clearances from combustibles:
Outlet: 8 Ft. (250cm) Sides, Top, and Rear: 4 Ft. (125cm)
•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.
•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.
!
DANGER
Carbon monoxide poisoning may lead to death!
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 (such as
pregnant women, persons with heart or lung disease, persons with anemia, those
under the influence of alcohol, and those at high altitudes) are more affected by
carbon monoxide than others.
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.

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.
ASSEMBLY 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: When installing wheels, point extended hub of 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.

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 electronic ignitor sends voltage to the spark plug.
The spark plug ignites the fuel and air mixture.

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.

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
•use of non-toxic anti-icer in fuel during very cold weather
IMPORTANT: Use a KEROSENE ONLY container. Be sure storage container is
clean. Foreign matter such as rust or dirt may require you to clean fuel system
often.

VENTILATION
OPERATION
!
WARNING
Follow the minimum fresh, outside air ventilation require-
ments. 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 (2800 square cm) for each
100,000 BTU/Hr rating. Provide extra fresh air if more heaters are being used.
Example: A 150,000 BTU/Hr heater requires one of the following:
•a two-car garage door raised six inches (15.24cm)
•a single-car garage door raised nine inches (22.86cm)
•two, thirty-inch (76.20cm) windows raised twelve inches (30.48cm)
!
WARNING

outlet. Use an extension cord if needed. Use only a three-wire, grounded
(earthed) extension cord.
Extension Cord Wire Size Requirements
Up to 100 feet (30.5 meters) long, use 16 AWG (1.0mm2) conductor
101 to 200 feet (30.6 to 61 meters) long, use 14 AWG (1.5 mm2) conductor

STORAGE 1. Drain fuel tank.
Note: Locate drain plug on underside of fuel tank. Remove drain plug to drain
all fuel. Be sure all fuel is removed.
2. Replace drain plug.
3. Add one gallon (4 liters) of clean kerosene to fuel tank.
4. Attach fuel cap.
5. Move heater forwards and backwards to stir fuel.
6. Remove drain plug and drain fuel tank. Be sure all fuel is removed.
7. Replace drain plug. Properly dispose of old and dirty fuel.
8. Store heater in dry place. Make sure storage place is free of dust and corrosive
