•Use only in well-vented areas. Provide at least three square feet of fresh, outside air for each 100,000 Btu/Hr of rating. This heater pro- duces carbon monoxide, which is listed by the State of California as a reproductive toxin under Proposi- tion 65.

•Use only in places free of flammable vapors or high dust content.

•Use only with the electrical voltage and frequency specified on model plate.

•Use only a three-prong, grounded extension cord.

•Minimum heater clearances from combustibles:

Outlet: 8 Ft.	Sides: 4 Ft.
Top: 4 Ft.	Rear: 4 Ft.

The Fuel System: The air pump forces air through the air line. The air is then 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.

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 buildup on spark plug

•the need of nontoxic 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.

•Locate heater on a stable and level surface while hot or running or a fire may occur.

•When moving or storing heater, keep heater in a level position or fuel spillage may occur.

•Keep children and animals away from heater.

•Unplug heater when not in use.

•When used with thermostat, heater may start anytime.

•Never use heater in living or sleep- ing areas.

•Never block air inlet (rear) or air outlet (front) of heater.

•Never move, handle, refuel, or service a hot, operating, or plugged- in heater.

•Never attach duct work to front or rear of heater.
