vapors are present.
• Follow all local ordinances and codes when using heater.
• Never use heater without properly installed vent piping and regulator.
• This heater must have fresh air for proper operation. If not, poor fuel
combustion and improper venting of flue gases will result. Carbon monoxide poisoning from backed-up flue gases could occur.
• 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. (188 cm)

1. Slide axle through wheel support frame. Install wheels on axle.
IMPORTANT:
wheel support frame (see Figure 2).
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.

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.
Exhaust gases are ducted out of the heater through a vent pipe. The user must
supply the vent pipe.
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: This system causes the heater to shut down
if the flame goes out.

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:
Use a KEROSENE ONLY storage container. Be sure storage
container is clean. Foreign matter such as rust, dirt, or water will cause the flameout control to shut down heater. Foreign matter may also require you to clean fuel
