VENTILATION THEORY OF OPERATION OPERATION STORING,TRANSPORTING, OR SHIPPING

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 29kw (100,000 Btu/Hr) rating. Provide extra fresh air if more heaters are being used..

Example: A 44kw (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  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 ignition control assembly provides power to the ignitor. This ignites the fuel/air mixture in the combustion chamber.

The Flame-Out Control System: This system causes the heater to shut down if the  ame goes out.

OPERATION
