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
resembletheflu,with headaches, dizziness, or nausea. If youhavethesesigns,the
heater may not be working properly. Getfresh air atonce!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.

petrol, naphtha, paint thinners, alcohol, or other highly flammable fuels.
•Never use heater where petrol, 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 a three-square foot (2800
square cm) opening 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-prong, grounded (earthed) extension cord.
•Minimum heater clearances from combustibles:
Outlet: 8 Ft. (250 cm) Sides, Top, and Rear: 4 Ft. (125 cm)
•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.

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
(For 90,000 and 150,000
BTU/Hr 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: When installing wheels, point extended hub of wheels toward
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 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.
The Flame-Out Control System (Optional Extra): This system causes the
heater to shut down if the flame goes out.

FUELS
Do not use heavy fuels such as 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 or PARAFFIN container. Be sure storage
container is clean. Foreign matter such as rust, dirt, or water will cause the flame-
out control to shut down heater (optional extra). Foreign matter may also require
you to clean fuel system often.
!
WARNING
Use only kerosene or paraffin to avoid risk of fire or explo-
sion. Never use petrol, naphtha, paint thinners, alcohol or
other highly flammable fuels.

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 (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 (15.24 cm)
•a single-car garage door raised nine inches (22.86 cm)
•two, thirty-inch (76.20 cm) windows raised twelve inches (30.48 cm)

To Start Heater
1. Follow all ventilation and safety information.
2. Fill fuel tank with kerosene or paraffin.
3. Attach fuel cap.
4. Plug power cord of heater into standard 240 volt/50 hertz, grounded (earthed)
outlet. Use an extension cord if needed. Use only a three-prong, grounded
(earthed) extension cord.
Extension Cord Wire Size Requirements
Up to 100 feet (30.5 meters) long, use 16 AWG (1.0 mm2) conductor
101 to 200 feet (30.6 to 61 meters) long, use 14 AWG (1.5 mm2) conductor
Heater will start when power cord is plugged into outlet. If not, push in flame-
out control reset button (optional extra; see Figures 6 through 8).
