THEORY OF OPERATION

Do not use heavy fuels such as No. 2 fuel oil or No. 2 Diesel. Using heavy fuels will result in a clogged fuel filter and/or nozzle.

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

VENTILATION

WARNING: Follow the mini- mum fresh, outside air ventila- tion requirements. If proper fresh,

The Fuel System: The air pump forces air through the air line. The air is then pushed through the 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 ignition con- trol assembly provides power to the ignitor. This ignites the fuel/air mixture in the com- bustion chamber.

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

outside air ventilation is not pro- vided, carbon monoxide poison- ing can occur. Provide proper fresh, outside air ventilation be- fore running heater.

Provide at least a three-square-foot opening of fresh, outside air for each 100,000 Btu/Hr rating. Provide extra fresh air if more heat- ers are being used.

Example: A 60,000 Btu/Hr heater requires one of the following:

•a two-car garage door (16 feet wide open- ing) raised 1 1/2"inches

•a single-car garage door (9 feet wide opening) raised 2 1/2" inches

•two windows (30 inches wide opening) raised 4 1/2" inches
