Dayton® Portable
Forced Air Heater
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 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 flame goes out.
Fuels
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:
•clogged fuel filter and nozzle
•the need of nontoxic
IMPORTANT: Use a KEROSENE ONLY container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the flameout control to shut down heater. Foreign matter may also require you to clean fuel system often.
