Master Lock BR150CE owner manual Theory Of, Operation, Fuels

THEORY OF	The Fuel System: The air pump forces air through the air line. The air is then
OPERATION	pushed through the burner head 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 electronic ignitor sends voltage to the spark plug.
	The spark plug ignites the fuel and air mixture.
	The Flame-Out Control System: This system causes the heater to shut down
	if the flame goes out.

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:

•clogged fuel filter and nozzle

•carbon build up on spark plug

•use of non-toxic anti-icer in fuel during very cold weather

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