110,000 Btu/Hr H.S.I. Series
PORTABLE FORCED AIR HEATER
FUELS
WARNING: Use only kerosene or No. 1 fuel oil to avoid risk of fire or explosion. Never use gasoline, naphtha, paint thinners, alcohol, or other highly flammable fuels.
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.
THEORY OF
OPERATION
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
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
Follow the minimum fresh, outside air ventilation require- ments. If proper fresh, outside air ventilation is not provided, car- bon monoxide poisoning can oc- cur. Provide proper fresh, out- side air ventilation before run- ning heater.
Provide at least a
