SAFETY INFORMATION

! WARNINGS

IMPORTANT: Read this owner’s manual carefully and completely before trying to assemble, operate, or service this heater. Improper use of this heater can cause serious injury or death from burns, fire, explosion, electrical shock, and carbon monoxide poisoning.

! DANGER

Carbon monoxide poisoning may lead to death!

Carbon Monoxide Poisoning: Early signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness, or nausea. If you have these signs, the heater may not be working properly. Get fresh air at once! Have heater serviced. Some people are more affected by carbon monoxide than others. These include pregnant women, persons with heart or lung disease or anemia, those under the influence of alcohol, and those at high altitudes.

Make certain you read and understand all warnings. Keep this manual for reference. It is your guide to safe and proper operation of this heater.

•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.

•Never use heater where gasoline, paint thinner, or other highly flammable vapors are present.

•Follow all local ordinances and codes when using heater.

•Use only in well-vented areas. Provide at least a 2800 square cm opening of fresh, outside air for each 100,000 BTU/Hr of rating.

•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-wire, grounded (earthed) extension cord.

•Minimum heater clearances from combustibles:

Outlet: 250 cm

Sides, Top, and Rear: 125 cm

•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 sleeping areas.

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

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 fi re or explosion. Never use gasoline, naphtha, paint thinners, alcohol or other highly fl ammable 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.

VENTILATION	! WARNING

Follow the minimum fresh, outside air ventilation requirements. If proper fresh, outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper fresh, outside air ventilation before running heater.

Provide a fresh air opening of at least 2800 square cm for each 100,000 BTU/Hr rating. Provide extra fresh air if more heaters are being used.

Example: A 150,000 BTU/Hr heater requires one of the following:

•a two-car garage door raised 15.24 cm

•a single-car garage door raised 22.86 cm

•two, 76.20 cm windows raised 30.48 cm

OPERATION	! WARNING

2.Fill fuel tank with kerosene or No. 1 fuel oil.

3.Attach fuel cap.

4.Plug power cord of heater into standard 230 volt/50 hertz, grounded (earthed) outlet. Use an extension cord if needed. Use only a three-wire, grounded (earthed) extension cord.

Extension Cord Wire Size Requirements

Up to 30.5 meters long, use 16 AWG (1.0 mm2) conductor 30.6 to 61 meters long, use 14 AWG (1.5 mm2) conductor

Heater will start when power cord is plugged into outlet. If not, push in flameout control reset button (see Figures 6 thru 8).

2.Repeat steps under To Start Heater, page 7.

	STORAGE 1.	Drain fuel tank.
		Note: Some models have drain plug on underside of fuel tank. If so, remove
		drain plug to drain all fuel. If heater does not have drain plug, drain fuel
		through fuel cap opening. Be sure all fuel is removed.
2.		Replace drain plug if used.
3.		Add 4 liters of clean kerosene to fuel tank.
4.		Attach fuel cap.
5.		Move heater forwards and backwards to stir fuel.
