115,000 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 Flame-Out Control System: This system causes the heater to shut down if the flame goes out.

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

Example: A 115,000 Btu/Hr heater re- quires one of the following:

a two-car garage door (16 feet wide open- ing) raised three inches

a single-car garage door (9 feet wide opening) raised five inches

two 30 inch wide windows raised eight inches
