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 2800 square cm (three
square feet) for each 30kw (100,000 Btu/Hr) rating. Provide
extra fresh air if more heaters are being used..
Example: A 43kw (150,000 Btu/Hr) heater requires one of the
following:
• a two-car garage door [4.9 meter (16 feet) opening] raised 9
cm (3.5 inches).
• a single-car garage door [2.75 meter (9 feet) opening] raised
15.25 cm (6 inches).
• two, 76 cm (30 inch) windows raised 28 cm (11 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 fi ne 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
thespark 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 fl ame goes out.

Note: If shipping, transport companies require fuel tanks to be
empty.
1. Drain fuel tank.
