VENTILATION
WARNING: Follow the minimum fresh, outside air
ventilation requirements. If proper fresh, outside air
ventilation is not provided, carbon monoxide poison-
ing can occur. Provide proper fresh, outside air ven-
tilation before running heater.
Provide a fresh air opening of at least 2800 square cm (three square
feet) 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 15 cm (six inches)
• a single-car garage door raised 23 cm (nine inches)
• two, 76 cm (thirty-inch) windows raised 31 cm (twelve 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 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.

ASSEMBLY
(FOR 100,000 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.

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.
